Similar to my exterience with the sanding disk, I switched to velcro but when I get more money to spend on my Shopsmith I will be buying two more original PSA sanding disks. Of course they are on sale now, but see other "Weekend Blog" tread to see why this is a bad time.
My refund check has been collecting interest for a while already....
Since this is a sort of sanding related post....... I have one conical sanding disk and 5 regular disks. Why 5??? Well I have one with fine, one with medium, one with coarse, one for sharpening and one with velcro. I should get a second conical for a fine paper... will have to see about that before the sale is over. (I tried the taking the paper off and putting it on the release paper then putting it back on...... it caught and did a nice job making my new 520 table top look old and used, so no more trying that).

The other thing on sale and treasure is the oscillating drum sander. If you do a lot of patterns for say router work these things are great. The other good thing about them is you only need one. They work with either the standard 2-1/4 drum sanders or the longer 6" one and you can also use the smaller dia. drums that shopsmith sells (1/2", 3/4", 1", and 1-1/2" dia) using the chuck. (The oscillating sander is just to the right of the top disks)
While we are at it yes it is nice to have 3 of the drum sanders too... same thing as before, one for each grit.
I have ordered the Inflatable sander... if it works like I hope it will then you might see a report on that sometime in the future. I have an up coming craft project that needs something like this. Besides I think this about does it for me owning every sanding thing shopsmith sells.... did I mention I hate sanding???
