Radius Cutter v2.0

[C-Bag]

Hi Paul,

Thanks. I would be glad to post some close ups. What exactly should I concentrate on? It's pretty easy to take it apart. Take to clamps loose and crank the adjusters to the end and pull the rails out of the linear bearings. The 3 parts, the work arm, cutter arm, and base, and then store them. The base rail is perfect for this kind of setup because it makes it easy to change radii. That was another problem with the original design. And you're right, it's far easier to prototype with this stuff than doing from scratch.

I think if you are looking for precision you would be pretty dissapointed by those little r-tables. But for me it was way easier to buy them than make them from scratch. I wasn't looking for precision out of them, I was just needing the geared rotation. It takes me so long to make something as it is I have to balance my time vs $$$. The weird thing about these tables is the mounting base slots are not centered to the table. I'm not sure why but I had to make my mounting plates take that offset into consideration because I wanted everything centered on the rails. This way if I wanted to change from convex to concave, just center the arm and lock it and unlock the cutter arm and go. That proved tough to do with the old setup.

It could be different now, but last I checked with the 80/20 site I didn't see to much machinery being made with it. I have seen DIY CNC router tables and that where I got my stash. I guess they had retired their CNC router and we're going to toss the 80/20 frame after they had taken all the goodies of it! Luckily the kid who worked there took it home and then decided to dump it on CL. Score, touchdown
