The Robo-Sander™is a heavy duty flush trim sander which will duplicate curved parts quickly and accurately.

It works in much the same way as a flush trim router bit, but unlike the router bit, poses little risk to the work or user and requires only a drill press to use.

It consists of a heavy duty sanding drum with a template guide wheel made from bearing grade phenolic resin . The guide runs on an oilite bronze bearing and is stabilized by two large fender washers. It comes with a 50 grit abrasive sleeve for quick shaping.

It can be used to shape parts which are much too thick to attempt with a router and there is no tear out even with highly figured woods.

I have been making my Robo-Sanders™ since 1992 . I take pride in my work and pay a bit more to use American made industrial quality materials. I personally machine the guide wheels to ensure their accuracy .
