[Above] Now take one of the 3 inch pieces and put it on the bar in front of the clamp head that you recently glued onto the bar. Mark the height of one of the side members of the head on the 3 inch piece. N.B. in this position the area above the head is going to be the fingers.
[Above] Using the other 3 inch piece, place it in the ‘finger’ area of the one you just marked. Center it from side to side and mark where it sits.
[Above] Clamp the two 3 inch pieces together and ‘somehow’ clear out the area between the ‘fingers’. I used a drill, saw, chisel, and rasp. The idea is to allow both pieces to freely move on the bar..
[Above] Put the threaded rod through the nut just so that it protrudes. Put one of those ‘finger’ pieces (we’ll call then jaws now) against the rod and tap it with a hammer to make a dent.
[Above] Clamp the jaw halves together, making sure the fingers match if they aren’t absolutely perfect. Using the dent/mark in the face of the one jaw part, drill a 3/8 inch hole all the way through ONE JAW PART, but just a tiny bit into the other one.
[Above] Now using a 7/8 inch bit, drill a well in the half with the through hole and a shallower well in the other half, but drill completely through that one.
[Above] By now the glue on the head is dry and you can cut off the extra protrusion from the 2 inch piece. Then round over the back of the head. I used a rasp.
