Project Information

I made this edge sander a few years ago with some left over three quarter inch plywood. The top piece is varnished birch for ease of sliding the piece to be sanded. The motor is a 1750 rpm furnace blower motor with a threaded mandrel and a large drill chuck threaded on to the mandrel. The height of the sanding drum can be changed by chucking the drum at different lengths into the chuck. After using it for a while and being dissatisfied with gouging the work if you fed it through too slow, I made a fence as you can see in the picture, that eliminates gouging. Sort of works like a router table fence. I found the fence most helpful in sanding the edge of a circle, set the fence so that the drum just touches the circle and then rotate the piece using the fence as a "stop". You may have to use a smaller drum for this. It of course doesn't oscillate but by using different grits of sand paper it does a pretty good job. It is also helpful if you have a small amount to pare off a piece of wood rather than use a table saw for a thin cut. All in all it gets lots of use, especially after the band saw cuts.

Great idea Jack. Now I'm looking for a motor. Actually I have a circular saw just collecting dust and rust and I'm thinking of a way to make a sander out of it. I need to drop the RPM's though.

I hope some of you will try to make a jig like this. You will be pleased with the performance, there are better quality sanding drums available, and Dura-grit and Kutzall have rotary type tools that would be compatable. The motor I've used should handle a carving tool without bogging down too much. I havn't tried this but plan to when my budget allows. Thankyou all for viewing.

VERY COOL HOMEMADE JIG/SANDER. CHEAP TOO, WHICH MAKES IT EVEN BETTER. I'VE GOT A COUPLE OLD MOTORS THAT WORK PERFECTLY WELL. MMMM, JUST MAYBE?

Hi Joez,
The motor is very quiet, as most electric motors are. This motor was used in a furnace blower, so you can imagine it had to be quiet. A vacuum cleaner motor is also quiet, it's what the motor is attached to that makes the noise you must be referring to.

Nice build Jack, and a pretty handy tool. I made one too and I love it (I think it posted here on LJ). I had my son-in-law, who is a welder, to elongate the chuck key using a long bolt. I'm glad I did. I thought the idea could be helpful to you. By the way, I noticed that your sanding sleeves are packed of dust. Clean them with a crepe block, or even with synthetic wine cork and they will last much longer.

Best,

Serge, Qc
