Nothing mind blowing here, just pleasantly surprised with the results. I got a cheap little 5" DA sander back when I was dabbling in wood working. It used hook and loop sand paper. Worked pretty well for the 3 or 4 projects I did.
I have a couple of 6" pneumatic DA sanders that use the sticky back PSA disc's and I use these for metal working. I have been doing a lot of work late at night or early in the morning fab work in the garage, so running the air compressor has been out of the question. So I started using the little 5" electric DA with decent results.
But the hook and loop wore out completely. Some looks melted.
I didn't really like the hook and loop, and prefer the bigger 6" disc's, of which I have a good stock pile, so I decided to try to convert it from 5" hook and loop to 6" sticky back. I picked up a 6" backing pad with a 5/16-24 stud for like 12 bucks.
3/4" aluminum plate for the adapter. 2-3/8" hole saw made a perfect round cutout. Drilled and tapped the center for the stud with a large clearance on the back for the Allen bolt and washer. Then transfer punched the 4 bolt pattern from the old pad onto the adapter, and drilled and counter-bored those. I was worried that the extra rotating mass or bigger OD would through off the DA randomness, but it seems to work great so far!
