>So I will admit, I am biased. I sell the Tim Skilton pads.
They are available from a number of sources though. Almost every mail order catalog has them, as does turningwood.com.
I used the Sorbys for quite some time, made my own, then when I was looking for what I felt was the best, I settled on the Skilton ones.
The Sorbys use a plastic body moulded around a round metal shart, onto the shaft a single density foam pad is glued and velcron glued onto that.
The Skilton pad uses a 1/4" hex shaft that is backed by a washer and goes into a higher density foam with a T nut. A softer foam is then glued to that piece of foam and the velcro is glued to it.
One of the major differences is that the Sorby is a bit more dense. really a personal preference for some. The other is the clearance. Since the Skilton is beveled from the washer, it allows close quarters sanding, as in an undercut rim, that the Sorby would not.
Depending on where you buy it, the price may be a wash. Definitly not the least expensive, but of excellent quality, and a good guy to deal with.
I like the sanding pads from Industrial Abrasives. They are the least expensive I have found $5.50 for the 2". The foam is tapered to get into tight places. The foam is also more flexable than the Sorby foam so less chance of "dig-in". The shaft is round so you can also use these holders in a home made pasive sander.
The discs from Industrial Abrasives are okay. The dics from Royce in Canada are cheaper. I figure on one set of sanding discs per bowl. I might be able to get more use out of a set of sanding discs but I like to work with known conditions when turning, freshly sharpened gouges when turning and fresh sandpaper when sanding.
John, Lee Valley carries power sanding kits, you get the pad with shank and 50 disks, 2" or 3" price approx. $40.- and $50.-
I got mine from stockroom supplies and also got the 3" rolls of Klingspor hook and loop sand paper, I'll give the webside so you can have a look, they are an Ontario comp., so no import hassle.
The other thing is to make your own, Darrell Feltmate shows an easy way of making them on his website. www.aroundthewoods.com/
>I use the disk and pads from Industrial Abrasives. If nyou belong to a club get an order together as a club and you can get the disk at a discount. Our club orders them that way and we get 100's at a time. We do an order twice a year.
