I'm not getting good life out of the 2-inch chuckable hook and loop sanding
discs I use for lathe work. The hook and loop material quickly loses its
grab and the 1/2 inch thick pad starts coming apart almost at first use. A
dmittedly this is with a sample of two discs. These are the Woodcraft disc
s and at about $12 apiece a bit too costly for one per project. I'm using
this on a right-angle drill at variable speeds with the lathe at about 300
rpm. Any thoughts?
Stop and feel the disk every minute or so. If it gets warm, cool it
with a blast of compressed air.
I used the "Wave" disks for awhile, but the glue is poor and the paper
flies off the hook & loop layer. Past few years I have used the AO
with lubricant from Klingspor with a chuckable hook pad. Between the
paper & pad I use the little 1/4" thick soft pad. When the soft pad
wears out just throw it away and put on another. That way if it gets
too hot it will only deform the hooks of the pad and not the chuck
part. That was my problem until I started watching the heat build up.
Here is one link. Most that I found today are 1/2 inch thick. Anyway
they come in soft, medium, and harder.
Being a cheapskate, when the hooks wear out, I sand them flat then
stick on more from some industrial hook and loop strips I bought at
Lowe's. Then trim the stuck on to the size of the pad. So my pads
are several years old.
Also, I chuck my disk holder and pad into a drill and resize to a
little less than 2" by holding it to the belt sander while both are
running. Seems to work better if a little of the sanding disk is
hanging over the edge all round.

Thanks, GW. Tell me more about the 1/4 inch soft pads. Source?
Do a Google for "3m stikit".
It's an entire product line aimed at the automotive finishing market.
Also used to fair out a boat hull, at least I used it.
Find an automotive finishes dealer and pick their brains for your app.
