Half Baked Garratt

Hi,

I hope everybody's New Year started well.

I have not made as much progress with my Garratt as I would have liked. The front engine unit is painted and re-assembled, and it actually runs nicely. I was a little nervous as I had completely dismantled it. The plunger pickups seem to be working nicely.

The real reason for the lack in progress has come about due to sound file testing. The AD60 slipping sound file has really had me thinking. The slipping method was quite easy to achieve. In contrast the engine units re-syncing (speed wise) with each other as proven to be very difficult to get right. I am getting there and the project is fairly easy to control now.

I have included two short videos, taken on my phone. Quality is not so good, sorry!

The locomotive is made up of two Garratt models. The front engine unit is freshly painted, the unpainted boiler section is from my second model as I don't want to handle the freshly painted boiler unit. The rear engine unit is about to be stripped of its old paint.

The decoders and speakers are just sitting there for testing purposes. This will be installed in the boiler section, mounted on a machined Delrin mount.

The front engine unit will slip. This happens with a large increase in throttle position. The locomotive is running at approximately speed step 6-8. The throttle is rapidly increased up to around speed step 18. The locomotive slips and the throttle is closed to arrest the slip. After the throttle has been closed, it is slowly opened once again and the model accelerates.

There is still some work to go in regards to the project but thought some may find it interesting at this early stage. Before anybody tells me, I know the chuff timing is not right. This will be sorted once finished ha ha.



Thanks for looking,

I am Slipping


G’day,

Well as the title suggests, I have been slipping when it comes to updating my blog. As Bob Stack mentioned in his Blog a few months ago, the Russians seem to have taken a keen interest in NSW modelling. I have had hundreds of blog hits coming from Russia! I have not received my new Russian mail order bride yet, as I am sure Australia Post have been quite busy between sorting Christmas deliveries and throwing everybody's Ixion 32 class models around!
Danielle and I are now feeling more at home in our new house so a little bit has been happening on the modelling front.
While on the subject of slipping, I purchased a Mansfield AD60 Garratt off a mate a few month ago. I have stripped the model of all its paint and have begun the long process of repainting and re-assembling everything. There are a bloody lot of parts to the Garratt, I hope I can get it back together!
Anyway while disassembling the chassis I noticed that there were four Delrin bushes fitted to the chassis rails. To me they looked like plunger pickup bushes. On closer inspection I discovered that they lined up perfectly with the driving wheel rims. The Mansfield Garratt was built from the factory with phosphor type wipers on the leading and trailing insulated driving wheels. While these tend to be ok, I prefer plunger type pickups due to their robustness. I find it interesting that the plunger bushes were fitted, without the actual plunger pick up from the factory? Lucky I guess, as drilling the holes in the chassis (like I did for my Trax Z13) is tricky work.

I turned up a few little brass bushes which locate the spring on the plunger. A trial fit to the chassis and they seem to work nicely. I am not sure why Mansfield ended up steering away from this type of pickup method. I hope I don’t find out once the model is all put back together.








The forward driver plunger pickup fitted

While my engineering brain was in gear, I wanted to come up with a neat way of attaching one side of the DCC connectors – the ones that will link the decoders to the engine units. I didn’t want the connector flapping about and I thought if the female side of the connector was fixed, it would be much easier to make the connections.
I ended up fabricating a little keeper which is soldered onto the inboard pony truck nut. The whole lot seems to screw together nicely and will keep the connectors out of sight, yet accessible.



AD60 Sound Project
The Garratt would not be complete without a new sound project. I have taken quite a few sound recordings of 6029 and have been filtering through and editing my little heart out.
Sometimes I have brain waves. Sometimes, well most of the time I don’t think about things enough. The Garratt however opened up a new opportunity in regards to DCC and realism. When it comes to realism, particularly for a Garratt, one thing that is so important is to have the exhaust of the two engine units falling in and out of synchronisation. While this effect can be done with only one ESU decoder, using two decoders (Yes it’s costing a fortune in decoders!) gives me the ability to induce a proper wheel slip in one engine unit.
It has taken me around three months to perfect the Loksound V4 slipping template however I now have a reliable and responsive project. I have designed the project so both decoders are using the same DCC address. As with all my projects, the throttle will once again control the sound flow – none of that ESU ‘Full Throttle’ function button pressing rubbish in my models thanks ha ha! When accelerating the Garratt, in the lower speed step region, if you open the throttle too much, one engine unit will slip. The wheels slip instantly and obviously the chuff rate rises to match. To arrest the slip the throttle must be closed slightly. Once the slip stops the engine units match their speeds and the locomotive will continue, as long as the throttle is not abused! This feature will allow the chuff synchronisation to be actually put out by a real slip. While typing this I have been testing it on the bench. It is not installed in the locomotive yet. It is looking promising however will most likely need tweaking once the locomotive is running. ESU V4 decoders are simply amazing when it comes to producing a realistic driving experience. If you can imagine it, there is most likely a way to build a template to achieve it.
Layout
Layout news, well there isn’t too much. The layout is still safely tucked away in Moss Vale. While I do have the room here, I will wait until the layout room is lined before I relocate it. I think I previously mentioned that I was changing my layout modelling location. I have been building bits and pieces for Picton now for many years. While a little sad to make a change, I have decided that I need to do something much simpler and concentrate on the quality. I have decided to build Fish River, I railway location on the Main South between Goulburn and Gunning. This location is quite interesting with it having two dead end refuges and a sand siding. The bridge over the river is fairly substantial and is located close enough to the station for me to model the whole location to scale. One of the biggest drivers for my change is model visibility and sound project staging. The mainline track at Fish River climbs steadily at both ends away from the station area with the refuges remaining level. This split and track elevation will stage models visually and aurally really well. I felt Picton was going to hide the models in the cutting a little too much.
I have drawn the entire track plan in Templot and have printed a full ten metre section and a four metre section out. The four metre section (pictured) will be used to build all the points on. The points have been drawn to NSWGR practise in OO-SF.
The sand siding ran very steeply into the river. I have plans for a sand loading platform however can find no information on whether the platform was actually built, what type of wagons were used and how the wagons were shunted. If anybody has any information I would love to hear from you.


Other

On sound news, once the Garratt is running, I will set up a Facebook site which will outline my projects and how they are controlled. I feel this will make managing peoples requests easier and give me the ability to monetise my work. Look out for Llewot Digital soon.

Well I hope everyone had a great Christmas, I had a good time at the Illawarra clubs Chrissy party. It was great to catch up with so many people.

This year Santa bought me a motorcycle rather than coal which was nice. The coal would have actually been quite handy as my 57 is still running around with no fuel.
Well that's it. Happy New Year and stay safe,
Linton

Trying to Build Realistic Sound Templates

Hi,

It has been far too long since my last update. Unfortunately I don't have much to report. My spare days are mainly being used to build fences and gates at this point in time. I have not been buying much in the way of trains lately however I did buy a Sound Devices MM-1 pre-amplifier to supplement my Rode NGT-3 microphone. I am hoping that this little device will help record better audio.

This post is purely to show case a few of my latest projects. While the actual audio sounds have progressed also, the main thing I have been working on is dialling in my Templates. I am trying to build templates and sound flows that help create more realistic operation. It has been a steep learning curve however I am enjoying staying up at night going over and over sound flow problems in my head ha ha.

Anyway, below are a few videos of my latest exploits.

A Post From Wichita Kansas

G'day,

It has been quite a while since I updated my blog. For some reason I have not been concentrating on it much lately.

Danielle and I have recently moved into our new house and it is basically taking up most of our time. I hoping to have a modelling space soon.

Meanwhile, I have been doing some work on ESU diesel templates and built up a new D57 class project. As most reader would be aware, ESU released their 'Full Throttle' feature recently. In my opinion, the new feature is just a new method of manual notching. They have added a speed hold function, coast function, eight notch function and a brake. The speed hold function locks the electric motor to the selected speed and allows the throttle to adjust the prime mover sounds. The coast function allows the user to force the locomotive prime mover sound into notch one/idle at any speed. The eight notch function does the opposite and forces the prime mover sound into notch eight and the brake function stops the locomotive (momentum settings are best set high) with any speed step selected.

I don't want to sound negative however ESUs concept is kind of ridiculous. Sure this has resolved the issue of separating prime mover speed from track speed however it is a messy solution. Like I said, in my opinion.

Here are the reasons I do not like it:

1. After having pressed the 'Hold' function and after having used the throttle to change the prime mover sound - once the 'Hold' function is released, the locomotive will accelerate or decelerate to the selected speed. To prevent a change in speed, it means that you must remember the speed at which you started. Some may not care about the speed change. Its a personal thing.

2. Pressing a function button to hold a speed, manipulate the prime mover noise, then deselect the speed hold to be able to slow down again is really quite stupid. For one, when shunting this is dumb.

3. Function buttons are prime real estate, particularly if you are a NCE user. Who wants to continually look at function buttons when shunting?

4. Consisting will be impossible with any other decoder or non 'Full Throttle' Loksound decoder.

5. The coast and eight notch ability can be done without function buttons.

I get the feeling that someone discovered a few check boxes that were not really used (they have been there for a long time), worked out that if you use a second sound slot as a control slot, that they could create a new method for manual notching. It seems the firmware update was used to add new function terms.

The one great thing that came out of this is the 'brake' function. While this has/is available on other decoders manufactured by others, it is a welcome addition to ESU.

When I built my XPT project, I built it with the ability for the prime mover notches to be selectable on the way down. This allows you to coast at speed or select notches at will. Having tried to create a better diesel ESU project, (I have never been satisfied with any diesel sound files due to the way they
drive) I was very interested to see what ESU had come up with regarding 'Full Throttle'.

Well as you can probably tell, I was disappointed ha ha. I decided to go back to the drawing boards and build a full eight notch diesel project that was completely driveable, sound and loco speed by the throttle. No function buttons.

As I have not recorded an eight notch diesel locomotive, I had no sound files to use in my new template. I ended up using ESUs EMD 645 project, deleted all the sound flow slots, substituted my new template and loaded the file into my Auscision 422 for testing. Last week I was able to run the 422 on Ray Pilgrims Bylong (thanks Ray). Rays layout is beautiful as most of us know but the main challenge was to convince Ray that a Loksound decoder, with a diesel file was useable without having to play the thing like a piano. It was great to see Ray find the project easy enough to drive. I have to admit, although in Candy, the locomotive looked great slugging up the 1 in 40 grades with it's prime mover sound adjusted to suit.

Anyway without banging on about it, I hope to modify my whole diesel fleet. This will most likely mean having to record quite a few locomotives so I have audio files to use. The 48, 45 and 43 are high on my priority list.

I have attached  two videos of the 422 and a video of my latest 57 file. I am sorry for the poor narration on the 422 videos. In regards to the 57 file, I have to make one small timing change.

I am currently in Wichita, Kansas and have attached two photos from the trip so far. One is the SR71, no more needs to be said about that and the other is a steam locomotive that I have no idea about.




Thanks for taking a look.

Andian Models LWW

G'day,

Just  quick post while I wait for a decoder to load.

My LWW is one of those projects that has been hanging around for years. I found it a challenging little kit, however it all went together ok.

One of the main reasons for the delay has been me figuring out how to mount the couplers and also how to add the brake detail. I had a few photos of the brake gear sent to me but it has taken me ages to figure out what I was going to build it out of.

Anyway, I turned up the air reservoir tanks on the lathe and modified bits and pieces I had laying around for the brake cylinder and triple valve. All in all it came out ok.

The couplers are the Sergent variety, mounted on a threaded brass spigot with a 10ba screw.

The brake shoes are Ian Lindsay castings, I do need to tidy these up a bit as the photos show some unevenness.

The timber platform was made by laminating timber to brass, milling the ends so it sits at the correct level and weathering.

Still to go is a general tidy up, adding the rest of the hand brake/ brake detail, painting and then just maybe, just maybe it will be finished! Finally!






Thanks for looking,

A revamped Z13, Longest EHO project ever and Most of a house


G'day,

I hope everybody is well. After a nice three week break over Christmas, I am now back at work and loving every moment - umm not.

It's not all doom and gloom though. Last weekend I took a trip to the Auscision shop. Not a bad shop, it's very nicely presented and has a lot of models on display.

While on the subject of shops I have to make mention of the outstanding service provided by Hobbyland.

http://www.hobbylandaustralia.com.au/.

These guys really know how to treat customers. I am looking forward to the release of their X200 rail tractors. Should be a good model.

On the sound front, my XPT file is now being distributed by Mike Walters at DCC Sound. I have been contemplating building a Paxman Valenta engine XPT project version also. This would cover XPT power cars up until Paxman VP185 engines were fitted during the 2000's. There is really only one place to now record a Paxman Valenta engine in a working locomotive that I am aware of. This place exists in the UK and the locomotive is the prototype HST power car 41001 which has been restored to operational status. There are a couple of obvious problems with recording 41001. One is that it's on the other side of the world and the other is that although it has a Paxman Valenta engine, the exhaust system is probably very different to that fitted to XPTs.

The first problem is probably the easiest to solve. I have a contact in the UK that may be able to help with quality recordings. I could also just go on a holiday!

The second problem is where my dilemma really lies. According to documents on the XPT, the power car exhaust systems were modified (attenuated) from those fitted to the HSTs. For model train engine sounds, I believe that the locomotive should be recorded from the outside, not engine noise specifically but the noise produced by the exhaust. If you have watched any HST videos you may have noticed that they have a very predominant turbo whine. I have read the term 'scream' to describe the sound of Valenta equipped HSTs. After talking to a few people and watching early videos of XPTs running, I don't think the turbo noise is apparent from the outside. The XPT most certainly didn't seem to scream along. This brings me to the point of decision. Do I bother building a Valenta project where I will have to mostly edit the turbo scream out or just use my VP185 engine recordings? Both are technically incorrect for a pre-2000's XPT. Just because 41001 has a Vallenta engine does not mean that it sounds anything like the Aussie XPT on delivery. I asked my Uncle the other day (as he lives on the main southern line) if he could recall any sound differences in XPTs over the years. For him, he thinks they sound the same powering up the bank into Moss Vale,

I would love to hear some other opinions. I can most certainly build a pre-2002 project however it may not be worth the time and effort.

Still on sound, I have revamped my Z13 project. I have cleaned up whistle transitions and added a few new features such as a function operated brake. I have included a video to show these recent changes. Sounds such as random compressor, injector, coal shovelling and safety valve are automatically played at random intervals. Some of these can be heard in the video while others did not play during filming.



Modelling - My EHO project continues. I have finished the basic underframe which includes a method for sprung buffers. I need to build some battery boxes and then add all the underfloor detail components. Still some work to go.




House - Our house is only a couple of months away from being finished, fingers crossed. Modelling will really take a back seat once we move in as I have about 100 years of landscaping work to do. Operation line my layout room will commence in the next month or so. This should create a nice area for the building of track work. Let’s see hey!

Thanks for reading my ramblings.

Until next time,

Linton

XPT Sound - Part 2


I hope everyone had a great Christmas. Danielle and myself had a good time however are happy to be back home after a fair amount of travelling.
Before Christmas I embarked on another XPT recording session. Blacktown railway station was a real eye opener. Never before have I seen so many ankle trackers in one place. Glad to be alive still!
I now have better XPT horn recordings. Still, these recordings have been by far the most challenging recordings to edit. For the XPT project, if the applicable function button is held the corresponding horn (there are three horns) will play a full 4 second burst and fall silent. If you only want a short horn burst you simply deselect the function quicker. No function room on this project for three separate long and short horns.
As the XPT project is really my first full blown attempt at a diesel project, I thought I would try and modify how the general diesel sound flow works. While I am sure there are third party sound developers out there that have already paved this path, I personally have not come across anything that suited me.
What didn’t suit me:
Generally when you accelerate an ESU diesel project, the model accelerates at a set momentum rate and the sound flow increases as per set thresholds. These thresholds can comprise of multiple factors. This all works well.
It was decelerating that bugged me a little. When a locomotive comes up to speed and no more power is required, say cresting a hill, accelerating up to track speed, drifting down a hill, the throttle is generally shut off an amount that suits the conditions. This could mean the throttle is simply backed off one or two notches or placed back into one notch (I won’t say placed into idle here as I will have a flurry of people tell me how a diesel locomotive should be driven). What I am trying to say here is that the throttle directly effects the prime mover engine revs. Track speed is a product of environmental and power requirement factors.
When it comes to models fitted with sound, generally the locomotive speed needs to be decreased so the sound flow transitions into lower notches. This in a way creates the sense that the locomotive is being braked by the throttle.
ESU have ways of detaching the engine sound to driving speed in the form of manual notching. This however can be a little cumbersome and I really wanted a method of doing all of this by throttle manipulation rather than function button playing.
Some may not agree with this thinking.
The XPT project:
Here is another badly filmed movie! It's a shame that the function buttons did not show up better in the video. You can just make out the selected function button by the border that appears around the box.


My XPT project now has the ability to let you travel at track speed and ‘coast’ with the engine in any notch, all selected with the throttle.
If accelerated up to speed step (SS) 22 (I always use 28 speed steps), the XPT engine will accelerate up to throttle notch 5 (max throttle setting for an XPT) and track speed will build as per momentum settings. I have used speed step 20 as one of the thresholds for the diesel engine sound being at maximum revs. This was to help simulate a hard working XPT while traveling at two thirds max track speed.
Once the XPT is up to speed (SS 22) and the throttle is decreased down one SS to 21, the XPT engine will progressively come back to notch 1. As the throttle is still selected at SS 21 the models track speed remains relatively constant. The XPT will maintain notch one and track speed 21 for good if no change is made.
Once the engine sound has settled to notch 1, by increasing the throttle one SS, back to 22 the engine sound will progress back up to five notch.
If for instance we are travelling at SS 22 again and we want to decrease the throttle to four notch without effecting track speed, you simply move the throttle to SS21, listen for the decrease in engine sound and then reselect SS22 and the XPT will remain in four notch. If three notch is then required move the throttle to SS21 again, listen for a decrease in engine speed and then reselect SS22 on the throttle. The engine sound will then remain in three notch however track speed is still set at SS22.
Once again if the throttle is increased one SS, to SS23 the engine will once again move to notch five.
Another feature is the incorporation of a function operated brake. When the braking function is used, the XPT will come to a stop faster. Braking times are adjustable by changes in momentum setting. When the brake is applied and released brake pipe sounds are heard. When the loco is stopped with the brake function, braking squeal is played.
For me this has added a little bit of fun to the project and once being operated on a layout, will make it quite a challenge to stop at a platform. Just like the real one.
As in my last blog posting, the project still allows for one XP power car to operate in service mode (engine speed remains in two notch). This is function button selectable and applies to the trailing power car.
I am happy with this project for use in the XPT. I think a diesel freight locomotive, for most prototypical realism would need a similar throttle notching set up for when increasing engine speed also. Perhaps one day.
Decoder Installation:
For the XPT I used two ESU V4 21 pin decoders, two ESU Power Packs and two Zimo LS 10 x15 sugar cube speakers.
The XPT install was one of the most straightforward I have carried out. The strobes, headlight, white marker lights (ditch lights) and red markers are all wired individually. The blue and green wires are both commons for lighting (markers and ditch lights). These commons run through two of the switches under the fuel tanks. The grey wire is connected to the red markers and the yellow wire is connected to both white markers and ditch lights. You may be confused here - I was. Weirdly if the blue wire (+) and the yellow wire are powered the white markers light up. If the green wire (+) and the yellow wire is powered the ditch lights illuminate. I found the lower lighting board impossible to open up for fear of breaking it. This means, to separate the white markers from the ditch lights will require the green common wire to be isolated. This will be possible by using an amplifier circuit switching the positive side, utilising one of the decoder logic only outputs.
The headlights and strobes are connected through a 4 pin connector. The lighting connections are already made to the 21 pin plug. All that is required is to map the functions correctly.
Pin 15 - Aux 1 [1] = Strobe - These have been mapped to flash when the horn is blown. May have to fix up the cabin disco. I didn't notice all the flashing in the window until I watched the video!
Pin 14 - Aux 2 [1] = White Markers – This requires soldering onto plug (yellow wire)
Pin 7 - Rear light output = Head light
Pin 8 - Front light output = Red Markers
I also swapped the motor wires around as I think they were wired backwards. I am using the same address for both loco units and have simply used the ‘reverse direction’ option on the trailing unit. This allows all the direction features to operate properly.




That’s About That:
I am yet to run my XPT set on a layout but so far running on the rollers looks favourable.
I need to thank Dave for being so helpful in allowing me to record the XPT. Much appreciated and a copy of the file is all yours if you want it.
Now to get on and weather the set. This could be interesting!
Thanks for looking. Have a great New Years!

XPT Sound Project



Hi,

My Blog has seen little action over the past few months. As we are still waiting for our house to be finished, not much has been happening on the modelling front. In saying that, sound project stuff has still been happening in the background, mainly due to it really only requiring a computer and a few gadgets.

I have wanted to build an XPT sound file since the Auscision model arrived. I reached out using social media for anybody that could get close to the prototype. Lucky for me a gentleman named Dave answered the call! Dave being a driver made recording sounds all that much easier. It's great having somebody that is able to describe how the locomotive works and what sounds should be where.

There was not much to the XPT recordings. It’s a five notch locomotive, has three whistles, no dyno, and no real compressor sounds to be heard. Pretty simple really compared to the steam projects I have been doing of late, however, like most things that seem simple, they rarely work out that way.

I have never been a fan of the way the ESU V4 handles diesel projects, hence why I have mainly stuck to building my own steam projects. I still use ESU diesel projects however, exclusively supplied by Mike Walters at DCC Sounds, mainly because they sound very good. For me the way in which the loco sounds is more important than having to live with a few ESU diesel project quirks. My layout is flat, however the prototype location is fairly heavily graded, particularly leading on to the viaduct. I actually like the manual notching feature as this is really the only way to simulate a locomotive in eight notch at low speed and still have the locomotives whole speed range available.

For my XPT project, I wanted to try and produce a coasting effect as in my steam projects. This means that the XPT can be running at max speed (28) and the engine can be idling without having to use manual notching. With my steam projects I can also simulate a hard working engine at low speed simply by using the throttle. I am still not at this point with the XPT project however I have a few ideas to explore.  

Another aspect that needed capturing is the ability to hold the trailing unit in two notch. As Dave explained to me, this happens so as to service the train’s power etc. He also explained that either the leading or trailing locomotive can be selected as the service unit and was a driver preference thing. As Dave prefers the rear unit servicing the train, that's how I incorporated it into my drive schedule.

Adding these features has really had me thinking. It has been great to do as I have learnt so much more about the ESU sound scheduling.

I have taken a quick video, using my phone (yes not very good I know), of the decoder on the tester. My XPT is not accessible at this time so this is as good as I could do.

The decoder is an ESU V4

Speaker is a Zimo Sugarcube

·       The first part of the video shows start up and notching up the engine using the throttle. It can be seen that if the throttle is cut by one speed step the locomotive engine heads to idle however the model will remain at the selected speed.

·      The second part shows manual notching.

·       The third part shows the notch two servicing feature, when shift is selected (F1) and then the locomotive is selected to reverse (trailing unit) the engine sound is locked into notch two.



The horn recordings I captured were not up to scratch. The horn heard in the video was recorded on the day with Dave however I cannot edit any part of the recording due to an echo.

I still need to add the brake release sounds, better braking sounds, whistles and perhaps a little track noise while coasting.

All in all it has come out ok and I am looking forward to getting the model running with it for testing.

Hope you enjoy the video and once again sorry for the poor phone recording quality.

A big thankyou to Dave for helping me out. Hopefully the guard is ok now after thinking I was trying to hijack the XPT. Much appreciated.  

If this ends up being my last post for the year, I wish you all a very Merry Christmas and a Great New Year.

NSWGR 36 Class - ESU V4 Project

Hi,

Just a quick update.

I have wanted to build a 36 class sound project for some time now. As I have three 36 class models, and they are one of my favourite locomotives, I was keen to get some recordings. Lucky for me 3642 was out and about last weekend in Sydney and on the Southern Highlander tourist train. With a few phone calls I was able to record 3642 being prepared for its weekend run.

I spent five hours hanging around getting in the way and recorded over 70 sound files. One interesting sound is when the headlight was turned on, the generator dips in sound and starts to work harder. I was able to capture this and then found a way to incorporate it into the sound schedule. This now means that the generator sound does not simply come on when the headlight is turned on. You must now start the generator (like the real loco) and then switch the head light on. I have tried to show this in the video however the random compressor noise interrupts a little.

I was also able to include sounds for the power reverser. When you change direction, the power reverser sound now plays. Hopefully it will suit the 38 project also?

I have included a video. The project uses the same throttle type control set up that I have explained previously. I have had a good time building this project, now all I need to do is paint a couple of my 36 class models!



Still on the sound front, I intend on recording an XPT in a few weeks. I have a great sound schedule ready and all I need now are the sound files. Regarding XPTs, I have to say that the Auscision model is very nice. I am looking forward to fitting sound to my set and adding a few bits and pieces to the coaches.



I am heading to Liverpool this Saturday, hopefully I will see some of you there.

Thanks,

Linton

Turntable, Version Three

Hi All,

Just a short post to show some of the latest progress on my 60 foot Sellers Turntable.

I think I am up to about version three with this turntable, however this time I  am much happier with the results and feel it is very close to depicting the Picton turntable.

As for the TT drive, so far I have used a stepper motor coupled to the original worm drive, stepper motor directly coupled to the bridge and now I will try out a toothed belt drive. The belt and pulleys are still a few weeks away so all effort has been focussed on the bridge itself.

The TT well has been modified since it's last appearance on this blog. I have added some extra height to wear the ring rail mounts and then profiled the well using casting plaster. This has allowed the support wheels to sit in the correct location.

There are still a few things to do. PCB and wipers need to be added for ring rail pickup, all the timber stuff needs adding, a tidy up of a few things and painting.








The photos show one of the handrail assemblies temporarily tacked to a few of the copper clad sleepers. Looking over some photos of Pictons TT, it is obvious that there was an angled handrail post fitted to the outer most sleepers at some point. This angled support ran from the end sleeper up to the handrail, attached at the first vertical post. I have a feeling that this angled piece was fitted post 1955 as a few photos in William Bayley's books show it without. I would like to add them for interest however as the layout is set in 1955, they should not be there. I would love to hear from anybody that has more information on this aspect.

That's it for now.

Thanks for taking a look.
