Dear List, I've just fixed an artist bench which was rocking obnoxiously from side to side, due to 0.08" of end play in the main screw (shaft?), measured between the pillow blocks. I figured that the only place where the end play could be easily removed was at the ends of the screw which it sticks out of the top box (the upholstered part) and where the hand knobs are attached. I got 1/16" thick washer (with a 5/8" ID to allow it to slip over the end of the screw) and placed it between the box body, and the hand knob on one side. Then to make sure that the shimming accomplished by the washer wasn't undone because the knob might slide outwards on the flat-ground area of the shaft where the knob's set screw is supposed to bear, I used to transfer punch to mark a spot on the flat ground, where I wanted to set screw to hit AND stay, drilled a dimple in the flat ground, which the set screw would land in as a home. And reassembled. The end play and the rock are now gone. Has anybody else gotten rid of end play an an artist bench's main screw, and if so, what's the right way to do this. Where does this end play creep in. I gather originally it is determined by the pillow blocks. If I did this wrong, I'm certainly willing to do it over, RIGHT. Bill Ballard RPT NH Chapter, P.T.G.
