Making Simple QC Tool Holders
vtsteam:
All pilot drilled.
vtsteam:
Drilling 5/16" to 1-3/4" depth for threading. After that I drilled 3/8 to 1" for the clearance hole.
But this turned out to be a mistake. The 3/8" x 16 TPI tap wouldn't fit in the clearance hole. I measured the 3/8" drill bit and it was .372" -- the tap was .376" so no go. I had to re-drill all blocks to 25/32" to clear the tap.
vtsteam:
Tapping 3/8-16.
vtsteam:
Clamp bolt holes all tapped.
vtsteam:
Slitting (with the newly cleaned up milling vice!).
