That is the whole point]need[/I] one. The "spongy feel, dimensional instability" has never been a noticeable/measurable problem for me. I prefer the velcro, and yes, I too have multiple disks, for sharpening purposes.

I forget who on this forum had a job testing sandpaper and reported that even "good" sandpaper is only good for ten minutes of sanding. It took Jim a lot longer then ten minutes (oakay, it took 4-8 minutes) to sand down that 2X4, and after he cleaned the sawdust off it, it looked ready to sand a few more of those 2X4's!!!:eek: I have a good supply of sandpaper right now, but when I need more...

I, too, hope they come out with a velcro version.

edit: Ahh, yes, here is the thread about sandpaper.

Hi,

Again I feel confused. It sounds like shopsmith invented this stuff... perhaps I would feel better if they had said new to shopsmith.

Several companies have been peddling this material for a while now, 3M, Norton and others. They are sometimes referred to as planer belts. Some are made from Alumina Zirconia. They have them for belt sanders and smaller diameter disk sanders as well as 1"x42 belts.

Now from what I see they did not mention what ceramic is being used but the color reminds me of I think 3M I'd have to check to be sure, they also use green for some automotive sanding products....

Now it could be I'm wrong but the description sure fits as do the results... the belt pictured above looks new, it is not, I've had it a couple of years and have used it a few time.

Hi Ed,

I, for one, never gave a thought as to who made this product. I never thought that SS had gotten into the sandpaper manufacturing business though. Your remarks did bring a question to mind: Are you saying that you know of a source of velcro backed, 12" round, ceramic sandpaper disks??? Please tell me it is so!!!:)

Hi Tim,

I have not looked for this type disk in velcro. I have looked for velcro disk as it seemed shopsmith was having trouble getting them for a while... and I was hoping for a wider range of grits, that I did find.

If I were truly interested I might start looking to see if anyone is selling them but I think I'd rather have the PSA style.... remember that you can really force the wood into the paper and I'm not so sure how well the velcro backing is going to like that????

When I first read the information my thought was "I gotta have some of these." Then I saw the PSA information. Changed my mind. I have been using the velcro attachment system for a while and really like it.

Not sure I want to go back to PSA even if the discs work as much better as they say. Could change my mind if folks rave about them here but for now I'll stay with what I have.

PSA vs Velcro-- when I saw the new pads I assumed they would be PSA, as I relate heavy duty action (and Jim was havin no mercy on them pads!) with a PSA application, certainly not Velcro. I've got both, so I ordered the variety pack for my PSA disc.
I'm thinkin that if they offer the new pads in Velcro I may get One 120 (or finest) grit, and it would probably stay on the Velcro-base disc most of the time. I Do like the light-n-soft touch of the Velcro fine grit.

I wonder if they will offer new style for the conical disc.

"Finer" gets my vote too.
If it'll clean up easy after grinding down a 2x4, it should do so with normal functions and a finer grit, seems to me (or not clog up at all in the foist place).

Ironic, or just dumb? I use a clogged up fine grit pad as a sort of "finer" grit pad, for sensitive jobs/touch-ups. If the new pads don't clog that may be a DISadvantage.

That doesn't work as well as you think it does. Instead of sanding the wood, worn clogged paper "burnishes" the wood, which does not smooth it as well and can keep finishes from adhering properly.
