I bought a Small 42" JET Belt Sander to grind tooling on for lathe work. It came with what was called a "Deluxe Miter" which pretty much meant that the "rest" was taller than usual.(JET(R) 2" x 42" Belt Grinder - Disc Sander Combo | JET(R) Metalworking Tools) I
Problems with Miter:
The miter is made of plastic mostly, and the angle adjustment isn't secured very well. It has a small bolt that has a plastic knob fitted to the top; meaning it can only be hand tightened. It's likely meant solely for wood work, and is fine for small wood grinding applications. But do to the pressure I have to apply in order to keep my blank in-place it likes to work its way out and I lose the angle that I have set. It also doesn't have a long enough supporting face for when grinding the left edge of the blank at a severe angle (45 degree grind for a Neutral 45 tool). Also because its made of plastic, its getting pretty worn after only some light use.
This is my idea for a custom Miter-esque fixture for my Belt Sander.
Apologies for the rough drawing, going to CAD it soon.
Pretty much make my own miter, laser cut a angle guide out of acrylic, attach to a slotted block... it's a miter. Tap it and add a bolt, or some all-thread and a jam nut, or a... to fix the angle slip.
Then attach a 1"x2"x1/8" aluminum tube to use as my support. Mill an extension that fits inside of the tube, to be flush with both the supporting edge of the tube stock and the face of the "table". Attach via set screws through the top of the tube. That fixes the support problem, when at a severe angle. Another idea I had was to make it function as a vice as well. With a built in clamp.
Has anyone had to do this? What did ya'll come up with? Or thoughts on my design? Sorry that this was lengthy.
