end steps

Postby andrewnummelin » Sun Mar 01, 2020 7:39 pm

Does anyone supply steps for the ends of 19th century coaches? I've looked through the lists of various specialist suppliers but I did not notice anything. With a couple of rakes of coaches under construction I do not really fancy making around 70 of the fiddly things by hand!

If you have some good drawings and photos(?) why not approach one of the etched kit producers to see if they will produce a set of etches for you.

Thanks guys.
I'm pretty confident that I would never be able to cut enough individual steps consistently by hand before deciding to take up a different hobby. So I think it will be a case of drawing them up and waiting until I can put enough (different) items on one sheet to make it worthwhile having a one off etch done.

Have you thought about making a master, moulding it and casting them in resin? You might have a high failure rate at the actual casting stage, and they'd be fragile in life, but it should be possible - I've cast down to 10 thou before, albeit for parts which will not be knocked.

Just thought that I would mention that It looks to me as if the drawing and the photograph do not correspond.
The drawing shows a semi-circular vertical part of the footstep whereas the photo looks more rectangular with rounded corners.

Correct. They are different designs for 2 different sets of coaches, one will be scratch built (eventually) and the other is for a rake under construction from etched parts.

Thanks for the suggestion: I had not thought of this option. Fragility would make one design impracticable but for another it might just be OK.

If you use thin brass strip which is correct for the width, you should be able to make the steps by scoring and breaking the brass. You can put a second, lighter, score to give you the position of the flange.

Couple of photos here of a cast of an RTR backhead. Note in particular the thin shelf above the firehole door. (The regulator, by the way, is a separate fitting.)

I would use Bill Bedford's suggestion to produce 5 or so masters, and then cast them all at once, so that you're not wasting resin by mixing up the minimum amount just to cast 1 step. I can give you pointers on casting in resin if you want to go down this route - and if that's not teaching grandmother to suck eggs!

A good suggestion, but there's still the fiddle of making and soldering on the bracket to support the step (unless one cheats and does not having them standing clear of the body).

A very nice piece of work.
