G'day All,
I've just finished modifying a Wohlhaupter UPA-4 boring and facing head for use in a Thiel Duplex 158 mill.
While doing the modifications I stripped the head down so I could both clean and machine it as required.
I decided to document the stripping and reassembly process and post it up here on the off chance it may be useful to anyone who might be considering doing something similar.
Cheers,
Greg.
