I dug out a box of 3M quick-change abrasive discs that I've had for a long time and then realized that I didn't have a spindle to mount them on.
After fooling around with a number of bad ideas, I tried screwing the QC on to a 1/4"-20 bolt and Voila! it fit perfectly. I cut off the head of the bolt and that left a 1/4" dia spindle that fits into the collet on my die grinder or into a cordless drill. The day was saved-- I didn't have to drive into town to find a QC spindle or order it on-line.

Watch out putting them in the die grinder. It likely rotates faster than the designed rating for the discs. It isn't pretty when a disc, even a small one lets go. :-o :-o :cry:

It can be fun to start and stop your air tool a few times then chase the disk around the shop. Air tools will unscrew and spit off the disk. :-D

Pete;
These are 1 1/2" discs that are rated at 18,000 RPM.

I'm sponsored by Norton Abrasives and learned a very interesting fact about discs. There's a code stamped on the metal rim that gives info on build date etc. I was told that even cutting discs have a shelf life. There are products out there that look like the real thing but aren't. Die Grinders are the most versatile of tools and I'd be lost without them. :cheers:

That's a nice sponsor , Mike. Norton makes the best abrasives that I've ever used but I like the 3M "Scotchbrite-type little discs for light-duty stuff.
I've never heard about a shelf life on abrasive discs but I do know that there are many counterfeit products out there.

My cut off wheel arbors are constantly walking off. Putting the disk on a 1/4" bolt holding it in place with s nut and chucking it in the die grinder has saved me many times.

Have you ever tried the 3M abrasive-bristle disc. They work great for light rust removal on steel and polish-smooth out aluminum.
They have little rubber-plastic looking fingers and the more they wear down the better they work.
McMaster-carr has them.

Doug;
Thanks for the recommendation. No, I had not heard of the 3M abrasive bristle discs before so I looked them up on Google. They sound great; I will try some right away.

The bristle disks work great. Just be careful on machined surfaces They are more aggressive than they look.

I have numerous sponsors including 3M. The rep from 3M was a little unhappy that Norton was supplying the abrasives but we'll try keeping the decals as far away from each other as possible. I'll post pics a little later of the attachment I have that holds the small discs for the die grinder. The Norton rep showed me pics of damage caused by substandard discs made in the Far East. Makes me shiver. A little tip for you Neil, You say you hate working with glass?. If you're using the woven fabric just spray a line of 3M Spray 77 where you want to cut the material and the strands won't unravel. It's like cutting paper, no runs. I even use the spray to bond material in place before laminating.

Thanks for your helpful advice, Mike.
