Hello, My Name is Dave Williams

I have joined the ME forum to ask if a member would be interested in making a working model of the Bulleid chain driven valve gear to help support the restoration of 21C11/35011 General Steam Navigation Merchant Navy class Locomotive.

We have access to a full set of drawings produced by the Southern Railway to make the model which we would like to be able to use on our info stand.

Kind Regards

Dave

Hello David

I seem to remember that model Engineer serialised plans for a Merchant Navy loco.

I think this could be quite a hefty undertaking, unless you just want a simplified model to demonstrate the principle.

This just simplified model that would have been used a training aid.

As far as I can make out the loco is stored at Sellindge near Folkestone so a bit of a way from Plymouth!. Also I thought most of the preserved Bullieds are on the watercress line. Mentioning this as anyone taking on the task might want to see the original.

I take it you have tried the guys in the Plymouth MES.

I haven't looked at the articles but I think the ME design was a rebuilt one, and I don't recall a published chain gear version though I think there was a letter or article once with pictures of the chain drive.

For a demo model of the drive I might suggest alternative approaches. Find someone who likes using CAD software to make a represational design that is effectively only 2D, then find a builder for a) a wooden version, hence larger, if you can find someone who has made a scroll saw wooden clock and likes that kind of mechanism. b) someone with a small laser cutter to make it in wood, c) someone with a bigger cutter or commercial laser to make the same out of sheet steel.

We have a set of three A0 drawings produced the Southern Railway in 1943 and the model would be mounted in case about 4' 6" x 2' and I would happy to email the drawings to any one interested.
