Hi Mike, Your post was reason enough for me. I'm buying one as soon as possible. Thanks!

Seemed to give excellent results, and of course Chris made it look very easy. I didn't notice any ragged edges from the oscillation. I think the rotation speed of the spindle is so much faster than the oscillation that that would never be a problem. He did warn us to plan on ruining one or two sets of hammers during the learning curve. The sander he demonstrated on had been borrowed from one of the exhibitors, Klingspor. It was a Delta BOSS, a very nice benchtop unit, retails for about $200, including several different diameter spindles and a built in vacuum system for capturing the dust. He used a small 1" diameter spindle for hammers already mounted on shanks, and larger 2" or 3" for unmounted hammers. Also, unmounted hammers could be sanded up each side against the rotation of the spindle, while hammers on shanks (at other than zero degeree bore angle) had to be sanded up one side and down the other, (or up the other side climb-cutting, and I can't remember which way Chris did it). I haven't made the leap yet, but I'm sorely tempted. I'm currently making a list of all the other tasks that sander might be used for. It's all part of the cumbersome rationalization process I need to go through before buying any new toy/tool.
