I have since changed that design to eliminate the dumbell. I was building a couple Ukes and a mandolin and as you can imagine the bodies were two narrow. So now it's just a rounded adjustable block design that works just fine.
There is a threaded insert in the adjustable block and I routed out a slot so it can slide up and down. In this pic you see a dovetail slot but it's actually routed through. It's the only pic I could find but illustrates the point.
This is the old version again but just to show that there is a threaded knob that goes through the back of the board into the threaded insert of the adjustable block to lock it down tight. I think maybe I did add a lock washer to it but it's probably not even necessary.
