Alvarado1357,
I watched your video and saw your neck attachment. I guess what you are asking is can you cut a nice tight fit like that. No problem.
I use a tight fit pocket to create holding fixtures for all sorts of stuff. I made one to create a corner finder and zero setting attachment. I cut a pocket in a small block of hardwood to fit a 2" square of acrylic. I screwed the hardwood to the bed of the cnc, and inserted my block. This holds it while I cut a circular pocket in one side to mount a piece of copper pipe. Then I flipped it over and cut the corner depression in 1/4 of the block. The corner lines up perfectly with the center of the pipe. I guess I need a picture of this to make sense of it all.
The point of all this is that cutting fitting joints like that are very doable. My machine is a joes2006.
I also built a similar fixture for cutting pearl. |
