9-14-08 I stumbled across some dxf files at CNCzone.com, one of which was a train engine puzzle. The material I used was some left over luan. It was about .180" thick. I had to scale the drawing so that the assembly slots would fit. The slots were drawn with square ends. This would be fine if I were using a laser to do the cutting but since I would be cutting this with an end mill modifications were in order. ![]() I don't have a place for all of the parts and seem to be missing a few. I think I will redesign a few pieces and maybe add a few to make everything work out to my liking. After that I intend to cut it in Baltic birch plywood for my soon-to-be six year old nephew. He is really into trains. 9-20-2008 My plywood came in on Thursday and I scaled the drawing up to allow for 6mm baltic birch. It is about 30% larger than the prototype above. I was able to use a 3/16 end mill since it would fit in the new wider slots. |
