I have been making a pin for a part I make out of 5/16" 316 SS and drill a interference fit hole for a 1/8" x 3/8" dowl pin near the end of the pin at 90* to the length of the pin (in the side). The pin is first bent to a 90* angle short leg being 1.5" long long leg being 5.5" long the small pin in the side near the end of the long leg is indexed by the bent end in the vise the small pin in the same direction of the short leg.
I have been doing this one pin at a time in my manual mill with a screw machine length drill bit to allow doing the operation without spot drilling first. You can tell when the bit gets dull because it walks on the 5/16" pin.
I am now buying a CNC bed mill and would like to make some sort of fixture to hold multiple parts to perform this operation. I am stumped on the design if I could use a fixture to hold say 20 of these I could use a spot drill then a screw machine bit to do this. I drill batches of these pins 200 + parts in a batch. I would really like to speed this up. Any good cross drilling jigs I could look at would be great.
