KR netters I have recently been working on my canopy frame. Today while trying to sand the foam inside the frame I was using a 3" PVC pipe with sandpaper attached to sand a concave surface. The pipe was too long for what I needed so I thought of my inflatable sanding drum. I inflated it until it was bulging then used it as a hand tool. This worked very good and I can see where it would be very good for any concave surface such as wing to fuselage areas. My inflatable sander is from Shopsmith and I used it extensively building my stick grip http://www.jackandsandycooper.com/grip.html and in other woodworking projects and now for sanding foam. I'm sure it would work on any wood lathe. Link below for anyone that may be interested. I have checked one other woodworking supply and it was about the same price as Shopsmith.htttp://www.shopsmith.com/catalog/html/sn_inflatablesander.htm
