Converting a miter saw into a disc sander

I have a mitre saw that I don;t use for sawing anymore. I loaned it out, and didn't get it back in very good shape. I have since replaced it. I would like to know if I could replace the saw blad and put sanding disc on it and use it for sanding; just like one of those combination disc and belt sanders. The motor still runs good and all I want to sand is balsa.

Don't see any reason why not--this works fine with a radial arm saw and I can see where a miter saw's adjustments could be very handy. Be aware though, that with a wood as soft as balsa it may sand too fast to be really controllable.

A Sears 10" sanding disk is 16 bucks

Worst that's likely to happen is that you find that you wasted 16 bucks. If you like the results there are fancier disks available.

  1. Do you really want to listen to that thing run during a sanding session? Darn near all of them are too noisy when simply running for a few seconds.
  2. I wonder if the bearings would last taking a load 90 degrees to the direction that they were designed to take a load and were they or the motor designed to be run non stop for several minutes at a time.
  3. I'd strongly suggest a 0 dedicated 12" disk sander, very QUIET by comparison.

I think I still have a ten inch disk (I said DISK!) that takes sanding disks. It came with my first Crapsman tablesaw back around 1980 . Want to say I've seen them since in a catalogue or some-such.

For safety sake make sure the sanding disk is rated for your motor speed. With a light easy touch, it may work for balsa.

IMHO. it's way too many RPM for balsa.. Try a washing machine motor and a wood disk in whatever size you want your paper... If you don't have a motor handy, trade the saw for one, someone out there needs it..

Not this one. I loaned it out and when I got it back, it wouldn't cut straight. I hate to throw it away because the motor is still good. . I agree with the light touch on balsa. Thanks to everyone who responded back to me.

hmm... had a problem like that on an old Craftsman and it turned out to be a little alignment/setup and tightening the bolt that the saw moves up and down on.. The guy that borrowed it (for 2 years) didn't notice that the bolt was starting to loosen and the zero clearance slot was about 3/4" wide from the play at the pivot!

The problem is in the pivot point. I tried to tighen it, but any tighter and it won't move up and down.It is a Pro-Tool mitre saw and since they are out of business, I can't get replacement parts. As a mater of fact, I replaced it for $69 with a Ryobi. The motor is still good and I hate to discard it.

Not having read all the comments on this subject I would like to submit my opinion any way.

I purchased one this weekend and it works very well for what I am doing. I set the saw at 22.5 degrees and sanded a couple of joints. They matched perfectly. The way I sand my balsa is to set the angle and draw a line on the wood, Then I sand down to the line. Works well. Thanks for your help.
