I picked up a cheap Aristocraft U25B in Chessie paint the other day and have been taking it apart so I can rebuild it. The idea is to get from the toy like unit I have into at least a semi-scaled sort of model. The photo above is the closest prototype image I’ve found to what is depicted with this Aristocraft rendition. So I’m stripping it down to the base parts with the idea to install my control system, batteries and sound. And of course, a bit of paint and detail work- it is a bit cheezy with the cast color parts. Yuck. So anyhow, I’m getting there. Below is an image of the original model. More in a later post.




Still have a ways to go on this but it’s coming out pretty good considering I don’t know what I’m doing 🙂 This is all cut out of .060 styrene sheet using my X90 3D router, Inkscape and Freebie CamBam.

I’m finding I much prefer to cut styrene as opposed to sheet plywood or blocks of pine. Styrene is an ideal material, it cuts easily, produces WAY less ‘chip dust’ and can be assembled with Testors sorts of plastic model glues and paints. This particular design is based on a photo from the VA Tech archive, a picture is in one of the posts below. I actually wasted only a little sheet on this one once I got the correct spindle rpm and feed rates figured out.


I think I have too many irons in the fire sometimes but here is the latest shipment from Shapeways. On the left is a 1:20 scale print of my trusty foreman model, in the middle is the secretary/waitress in 1:24 and to the right is the conductor in 1:29. I’m very happy with the quality of the foreman fellow in the larger size, the details are quite good. The waitress was a real pain to get printable but she came out pretty good too. The Conductor in 1:29 had to be printed in the ‘detail’ plastic but it was worth it I think.
