Ok guys I am finally pushing forward on the reversing valves. Making the valve blanks was pretty straight forward. turn the material to diameter, drill the center chamfer the side and part off. I then machined the pot chuck and faced off the back side I did 16 just for extra margin.
Today I finally got to the interesting part milling the slots. Ir i was just going to do one or two the obvious choice would have been to set them up on the mill. but I had to be different. the first thing I did was make an indicator holder. The other thing was make a spindle nose protector that doubles as an indexer the index stop is attached to the indicator holder. As for milling I set the hand piece for the dremel in a QC boring bar holder. Once the contraption was in place i centered the end mill in the hole of one of the parts then lowered the holder the required amount and set up my thread stop as a cross slide stop . So I pop in a blank in plunge cut .020 crank the cross slide between the stops and repeat to depth. Then rotate the lathe spindle 180 and do it again.
