I am in the process of assembling a 2" x 72" belt grinder. I started a new hobby, knife making. I needed something bigger and better than my 2" x 42" belt sander. I purchased a basic frame. Then I got the new motor and VFD, and 2 of the 4 wheels needed for the grinder. I have assembled everything up to know. I have test run the motor with the 5" drive wheel successfully. Here is the belt grinder so far.
