I finally got the broken tap out of the first toolholder. It's amazing how a problem like that can take the wind out of your sails. I decided to use that piece for 1/2" tooling. The horizontal mill makes short work of cutting slots in one pass.
I decided to experiment with ways to speed up cutting dovetails. I drilled two holes through the blank in the notches of the dovetails to take out some of the waste and made a jig to get the spacing right on future blanks. Then I used two 4" x 3/4" stagger-tooth cutters that Shawn had sent me to gang-mill down to the 1/2" dovetail depth. I'm really getting to like the power of a horizontal mill.
This toolholder was slated for the large tooling that came with the lathe, as well as the tangential toolholder I had made for it. This meant a 1 1/8" x 3/4" deep slot. Back to the 6" x 3/4" cutter. Two passes had the slot cut to size.
It's amazing how fast a pile of swarf can grow when you have the power.
The finished toolholder. Only a dozen or so to go.
