The pieces would be cut from 1/4" and 3/8" steel plate. I designed it as a single piece and then broke out the different pieces and separated them according to thickness.Everything was designed entirely in EnRoute using the various vector tools. The MultiCam CNC plasma cutter made quick work of cutting the files and they were plenty accurate enough. A little touchup with a sanding dis is all that will be required before I begin assembly. The quarter inch thick files looked like this.
The 3/8 thick files were these.
As soon as the pieces were cool enough to handle with my bare hands I mocked up the pieces to see how it looked. It's going to be very cool and should work real well to control the train. Now it's time for a little grinder work and then I'll light up the welder and wrenches to fasten the pieces together.
