Making a rotary vane (lamellar) air compressor 11

[Norppu]

This time it will be another steel puck for the compressor.
There will be a precision recess for a shaft seal.
I will be using my Wohlhaupter UPA3 boring head to make that one.




In this video I am using:
- Weiler Matador SV (1972) Lathe
- Schaublin SV-51 (1955) Milling machine
- Solberga (1975) Drill press
- Wohlhaupter UPA3 Boring head

Im was wondering when you set the part up for boring the hole , you used an 8mm pin to find center . Did yo use any special method to oriented the bolt circle for the ball end mill operation ?

Actually the endpoint of that groove was fairly simple. I just placed the corresponding innder puck over that workpiece and used a drill to mark the place, Sorry about leaving that out of the video.

Fascinating video! I can't bring myself to drag a micrometer across a turned edge like that, without a de-burring effort first.

That insert leaves a very small burr. It becomes almost worse if I touch that corner with a file.
