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.

    Very nice work indeed.

    Re the extension bit to the last sleeper. I don't know about Picton TT in 1955 but I can honestly say that I have not seen any TT that is without the end sections, they can be either straight out, angled or in many cases a scoop type that finished around half way in height to the other staunchions.

    Reasoning is that it was a safety thing, although only shallow at that end, a trip & fall could cause serisou injury.

    The other & most likely reason for it is that the fireman had to stand on the departure end of a balanced TT, his weight, including lighter people, was enough to counter the balance & the bridge dropped at that end, he had to stand well back on the bridge until the engine had completly worked off, not a lot of space was there & the rails were very much a safety but leaning posts.
