Cutting in the dogs on the next batch of bottom bracket tap bodies using a two inch diameter shell endmill in my 1958 Bridgeport milling machine.  The tap bodies are held in a three jaw chuck on the super indexing spacer which allows the tap body to be rotated 180 degrees after the first milling pass is completed.

Tapper bodies have moved from the lathe where a 20 degree chamfer was turned and are back on the Bridgeport milling machine for step no. 11 -milling the flats for the stainless steel handles.  The bodies are secured in the Super Indexing Spacer and a two inch diameter shell endmill is used to machine a 2mm deep x 40mm long flat.
