Prop them up for easy access. Oh, I = use three clamps. One on each end and one in the middle. I use 1/2" x 3/4" Oak = strips w/ "camper foam seal" on one side to grab/cushion the shanks. The middle = clamp is slimmed down, so it'll go between the shanks. The bottom of the clamps = sit on a piece of 1/4" plywood that is laid over the wippens. I use a 3" Rubber = Sanding Disc. The sticky backed discs, I get from 3M. I like to use 40 grit, as = it leaves a little "roughness" for the backchecks to "grab". With a little = practice you can become very accurate at getting the "proper" arch. (Go slowly = and move the drill/sanding disc in the desired "arch") This is, I liken, much = like "sculpting" and can be kinda fun.<G></FONT></DIV> <DIV><FONT face=Arial size=2>Oh, BTW, you could use Spurlocks Hammer = Shank Clamp instead of the Oak Thingees I have. They're made out of Aluminum Channel = and have rubber in the channel to protect the shanks. A good tool! = Reasonably inexpensive, well made. I hope this helps.</FONT></DIV> <DIV><FONT face=Arial size=2>Best Regards,</FONT></DIV> <DIV><FONT face=Arial size=2>Joe Garrett, R.P.T.<BR>Captain, Tool Police<BR>Squares R I</FONT></DIV></BODY></HTML>
