Okay, maybe most of the people here are pros/advanced hobbyists, and maybe most of you already have a dedicated spindle sander. Or just already knew about Lee Valley's product, so I'm not telling you anything new here.
But for those of you, like me, who are just getting started and have already blown the hell out of your budget on the woodshop "neccessities," let me give you the following advice for the below product:
I never understood the wisdom of putting drum sanders onto drill presses, figuring that they would eventually destroy the accuracy of the drill press. This will take your fear away. I chucked-it-up last night, and DAMN this thing is sweet. I now have the ability to machine-sand curves, and it cost me a whopping $30 for the drum sanders, bearing support, and replacement shafts you need to use the bearing support. It works like a charm.
