I want a spindle sander and as everyone knows they are expensive. I have been toying with an idea that I can't find a flaw in. So tell me why this wouldn't work.
Take a drill press with a sanding spindle in it. Make a big table. Add a gear motor on the DP with a arm connected to the arm on the DP so that as it turns it raises and lowers the spindle. (think steam locomotive wheel) Other motor takes care of rotation.
Seems simple enough to do and wouldn't have to alter the drill press. Just remove a handle maybe and replace it with a new arm. Could be a quick release joint so it could still be operated manually....
Thinking out loud again.
