Used spotting drill to start the hole for what will eventually be a 3/8" hole. For now it will just be drilled to 3/16". I'll still need to drill this hole on the two other pieces, however, their angle had the 3/16" hole already, so I'll use that for positioning.
The holes for the 2 1/4" bolts have been updrilled to the dull "D" bit on 3 of the 4 attach block assemblies.
Hopefully the new "D" bit and reamer will show up tomorrow.
