[Above] Now turn the bar over to expose the bottom side. Put both jaw pieces on the bar up against the head. Measure in 2 inch increments from the jaw pieces down the length of the bar. In reality one in increments is better, but it’s double the work too. Using the rat tail rasp cut half circle stops into the bar. N.B. More can be easily added after the clamp is finished. Don’t go all the way to the far end.
[Above] Round over the far end of the clamp bar. Drill a centered 1/4 inch hole about 3/4 inch from the end. Now is a good time to sand the clamp bar.
