You guys have got me thinking about homebuilt cnc routers. I was thinking about how to build my own track link masters for casting in zinc alloy. At first I thought that I would have to pay through the nose for a "actual" machinist to build them. I had also considered rapid prototyping or 3D printing. I like this idea better! A foot square machine would do fine. Something like this:

It might be interesting to make a flat pack tank. Sadly, it doesn't look like there is much price difference in the sizes. The big ticket items are the controllers and motors.

Aluminum molds would work well for resin casting. Aluminum masters could be cut for making molds of high temp silicon for casting in zinc or tin alloys. I suppose a smaller machine could be built........

Didn't look at it real close, still it caught my interest.

Philistines. To get to the point of this resurrection, I've been looking at DIY CNC machines and I have found the Mechmate http://www.mechmate.com Free plans to download. Some weird clauses in the EULA, but the design looks decent, and will be sturdier and more professional looking then other plans that use MDF.

Considering the quantity of parts we might need as a whole I think we would be better served by finding a Tech college nearby and getting them to use their waterjet. For those of you in the Pacific Northwest that would be Vashon Technical. Aahz. --~--~---------~--~----~------------~-------~--~----~ You are currently subscribed to the "R/C Tank Combat" group.
