Interesting stuff, may I ask who's kits are the 7mm class 25's in the background of the pics do you have any plans to actually produce 7mm parts to sell ?

 

Cheers

The 7mm class 24s and 25s in the background are Steve Beattie resin shells purchased from ebay.

I have got 8 bodies, some etched grills and some bogie castings. The quality of the steve beattie bogie detail castings are not too good so I might try to produce some resin castings (if I did I would need to get another sideframe printed with the details not attached to alow it to be cast). I would also like to try a class 25/3 cab in 7mm as the 25/3 in the picture is a modified 25/1 shell and I'm not happy with the windows.

The pic below shows a test of a 7mm cab profile printed in clear material to see how well it matches the Steve Beattie body.

There are 4 different materials used in the pic above-

Right cab - white strong and flexible

Left cab - white detail

Bogie - Black strong and flexible

7mm cab profile- Transparent detail

The pic above is a close up of the 7mm bogie to show the roughness of the surface. Looking at it in the flesh I would say it is fine for a bogie and the black material it was printed in gives it an almost dirty/oily finish and could be fitted to a model without painting. The cost of the sideframe in the black material was ??15.

After seeing a thread on the old forum about 3D printing I decided to have a go myself. As recomended on here I downloaded a free cad drawing program and set about learning how to use the program. Here are the first results-

First I tried a class 24 roof.



and developed that into a class 25/3 cab in 4mm.



most recently I had a go at a Class 24/5 bogie in 7mm.



I have just got some parts from the 3D printing company (shapeways as used by others on rmweb).
