if anyone is interested. i have a box of the clamps at work. they were mis-ordered. for the cost of a self addreded stamped envelope, i will gladly mail one(& only one!) to you. they are 1/2" I.D. & they are similar to the one pictured in duster daves earlier post, except they are aluminum, & have a single 8-32 allen head screw. they are 3/8" thick, & 1-1/8"O.D. pm me, & i will reply w/ my mailing address, so you can get the s.a.s.e. to me. only people that NEED one, please(assembled, running motor with retarding timing). it is a box of 25, so first come, first serve.
thanks-jeff
p.s. please put 2 $.39 stamps on the envelope, i'm guessing one clamp weighs between 1 & 2 oz.
