King Arthur's Tools Inflatable Long 4-1/4 Inch Drum Sander For Use With Guinevere Sanding Systems For Woodworking, Sanding and Finishing

great concept. works great.. at first. but doesnt hold air very long. supposedly if sawdust gets in, it doesnt allow the "rubber band" to seal the hole, so it leaks and becomes useless. i would give it 5 stars if it held up.

Use it all the time. I use all of the sanding drums and balls, every size, even keep extra rubber replacements on hand. Absolutely indispensable in my wood sculpting shop. You can adjust the pressure from soft to firm. Sanding sleeves last a long time. Don't bother with the pump, I just use my air nozzle and give it a quick squirt, hold at an angle if it inflates to much, be careful not to blow it up, really quick shot of air.Highly recommend all their products.
