Producing corrugated effect for wagon sides
Producing corrugated effect for wagon sides
I'm considering different ways to produce a corrugated effect for wagon sides.
(A) heated brass former and press from sheet pkastikard
(B) CNC milled from solid
(C) resin ( chunky ? )
Etched brass ??
I want to produce 20-30 wagons
This is the prototype the GSR/CIE Bullied open ( triangulated chassis , good old Oliver !)

That better?

Dave,
Have you considered using a form tool and take-away food container weight aluminium?
Cheers,

hmm, would it be rigid enough ?, to allow handling, most food containers have extensive edge folding to increase strength

True, but some are heavier than others. Baking or roasting pans might be worth a look. The corrugations would add stiffness.

Re: Producing corrugated effect for wagon sides
Get the body made up as an etch to produce flat sides with the rivet positions half etched to press out and half etched lines to give the fold over at the top. Cast the corrugations individually in resin. On the etch have fine lines half etched or less to show where the corrugations will be glued. Then glue the resin castings in place. That of course would only work if the wagons are going to run loaded since the inside would be flat.
There is probably a piece of angle iron on the inside of each corner which could be added using suitable size of brass angle soldered in place.
A nice challenge.

3D printing might be a bit too thick but would give you the effect.

You may care to explore the Wills products from Antics @ http://www.anticsonline.co.uk/2140_1.html
Wills Kits OO Building Pack Corrugated Iron SSMP216
Wills Kits OO Building Pack Corrugated Asbestos SSMP219
If you feel so inclined, use takeaway stuff for moulding onto these sheets and simply coat one side thinly with Araldite.

Slaving away still on GCR stuff ...
Re: Producing corrugated effect for wagon sides
My current preference is a heated brass form tool to press the corrugations. Initial half-assed ! Tests show it has some potential. it also make the interior correct , as it effect it duplicates the prototype manufacturing process
I have no experience of the technique in any final form.

Re: Producing corrugated effect for wagon sides
Another process would be to vacuum form the sides. This would require a mould to be made in something like MDF and have some small holes drilled in appropriate places to allow the air to be removed. See http://www.technologystudent.com/equip1/vacform1.htm for further information. Vacuum forming machines are common in secondary school workshops and it is not too hard to find firms who do this sort of work. It is not too difficult to make your own.

Another process would be to vacuum form the sides.
There were some details of 'home' vacuum forming in snooze 199, p14.
This was also featured in the demonstration at Scaleforum, I had an interesting discussion about the use of this process in the domestic environment.
I think that, whatever method is chosen, the biggest difficulty will be the tapering ends to the corrugations and keeping them regular.
Good luck with this, looking forward to more posts,

I have a Proxon MF50 CNC mill, so its possible to produce reasonably fine form tools , as you say the tapering of the corrugations is a key aspect. I wouldn't consider doing this without the mill and the idea is to make all the corrugations on one side in one action.
vacuum forming , hmm?

A little bit late, but there is already a kit on sale in cast resin - here
Mind you, a little expensive for the number you require.

I'm personally not happy with the quality nor does it convey the flimsiness of the sheet steel sides. I have an example of the kit you linked
