My disc sander experiment

[bugzilla46310]

Since I can get abrasive blades for about 1/2 price of sanding discs, and when I cut metal on my table saw I use the blade to debur the cut, thought I would try one on my trusted Simplex sander. Had to drill and tap the shaft and fabricated a thick spacer washer then a heavy washer to clamp that to hold the blade. Tried it on a 2x4 and it worked good. Left a finish of about 40-60 grit. Now to see how long it lasts.

This is dumb/dangerous.

Hope a "wheel" never explodes on you. Those are not meant to have force applied to the side, or for soft materials.

At least you went with a high quality disc brand....

I was/am hoping that he is just using it as a saw, so no side loading. But without a guard, it is a bad idea.

Would have been the icing on the cake to see a black and Decker disc

I didn't even think about the guards until after.

He does appear to be side loading, look at the tool rest and the dust already in the disc

What is your machines operating rpm? I would fabricate a guard...

I use 20" disk at work to cut case harden steel linear rails from 5 mm all the up to 65 mm. We sometimes apply side force to the blades and when they explode, it's very dangerous even with the thick steel guards we have. Will make you poo your pants.

WOW!

All I will say.

The cutting disc is against the 14” steel disc that the paper disc would be glued to so there will be no side loading. Guess no one ever saw a disc sander with out the paper disc on.

Still not a good idea, but it doesn't matter what any of us think.

Well you didn't say that, did you? It reads as though you replaced the whole sanding stuff end with a cutoff wheel. I would still be more concerned about an abrasive cutoff wheel breaking more than a sanding disc.

Bell helmet use to have an advertising slogan: "if you've got a $10 head, buy a $10 helmet." Something about this thread brought that back to mind.

Are you the same guy that made a Youtube video using old CD's as a cut off wheel?

No

The backing plate makes it a LITTLE less sketch


But my question is how is a abrasive disc cheaper then a proper fiber disc?
If you post your requirements these tool hounds will sniff out a bunch of deals on the proper abrasive.

Until then, keep out of the way and be ready to change your britches

They're like $10 at Grainger, So I have to assume there's plenty of options in the $5-$15 range

Backing plate or not, thats a bad idea.

Get a little wear, or impact/bump it and the wheel will separate at high speed.

Those are not made for side load, supported or not.
