Eric - I bought the Sandrite years ago to buy time with my family. I used to do all my sanding by hand. That little bow sander is extremely handy and can do all the sanding you need. I make them myself with plywood and belt sanding material. It's basically the same outline and concept as a hacksaw except with sand paper. I have one with half inch and one with one inch belts. They're awesome. Even with the Sandrite, I use them on heads, around necks and any detail sanding I can't get to with the Sandrite. On my Sandrite, I have both a 6 inch and a 2 inch drum. Many people how I manage the production I do. The Sandrite is a big part of it.
Get one. You'll never regret it. I wish I had 2...
