Comments sought on new build: A CNC Router for RC Gliders and Planes

[Clive S]

If I had a 3D printer I would.....now if there was someone out there who could make those then I'm sure I'd be in the market for 3 of them (plus a Nema34 one...).....

I made a few on the 3d printer but they take quite a few hours each. But since then I have made them on the mill. I have made them with various plastics and also the reconstituted rubber from tyres that they seem to make decking and posts out of but that is full of crap and holes.
.
On the mil they take about 20 min with the tool changes once setup. For the undercut I use a T-slot cutter.
.
The order in the way I do it is from the solid drill the 4 holes then reduce the block down, hollow out the centre, profile the outside, do the undercut then turn the piece over in the vice then cut the bottom off to release the part. Then put it back in the vice to profile the gland hole out. This was all done from a dxf file with Vetric Aspire ..Clive

edit Tool used 6mm endmill, T-slot cutter and drill.

Here is a link to buy them http://www.soigeneris.com/nema_23_st...r-details.aspx but you would need to check carefully if they fit
