Building a Disc / Belt Sander Combo

July 21, 2016

 

 

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.
