PART 1:
This is Part 1 of a detailed build on my homemade combination disc and belt sander. In this part I go over the build of the base and disc sander portion. In Part 2 I finish the sander by making the belt portion and dust collection ports.
I designed this sander using Sketchup on the computer before building it. This allows me to save time in the build process and I don't have to figure out as much on the fly. It is designed for a 9" self adhesive sanding disc and a 6"x48" sanding belt. The motor is a 3/4 HP furnace motor that I purchased at a surplus store.
