How To Use A Wohlhaupter Boring And Facing Head. UPA 2 and UPA 3

Showing the settings needed to bore and face using Wohlhaupter UPA 2 or UPA 3 Heads.
CORRECTION !!! to my description of using the stop plates for facing to a specific diameter. You CAN use the handle  and when the stops hit the pin, the TOP pin will pop up and stop the feed. That was the first time I had ever used it for facing and I think that I was being over cautious. Sorry for the error.
