Assembling the jig and drilling the safety and trigger pin holes.
I switched the clamp to a metal clamp that was made for drill presses for the second Lower. The metal clamp was much stronger and made drilling easier. I went a little too fast with one of the holes and there was some binding that stopped the drill. I tapped the jig off the bit, added some WD40 and went slower.
One other note, I am doing two lowers so I wanted to drill these holes with fresh new bits. Drilling the holes for removal of the material in the trigger pocket may wear the bit so I wanted those holes drilled with new bits.
