Alex Melton Posted July 11, 2017 Share Posted July 11, 2017 Hello, Currently, I am making my knives using a 4x36" belt sander. Although it works for many applications, I want something more. I can't really make the convex or concave bevels I want by using it, so I've set out to try and fabricate my own 2x72" belt grinder. The first step I am taking in the fabrication process is making aluminum wheels for the belt to run on. I cast the aluminum into old green bean cans. After taking apart the cans and getting the aluminum block out, the next step is to machine the aluminum into a perfect cylinder, make sure the sides are flat and can hold the bearings, and then round off the sides to allow proper tracking. One problem, though. I don't have a lathe to do this on. I've seen YouTube videos showing how to turn your drill press into a makeshift lathe, so that's what I was planning to do. The thing that troubles me is this: What tool should I use to machine the aluminum on my makeshift lathe? Should I use a cold chisel, or is aluminum soft enough that a woodworking chisel could work?
