[PSUBS-MAILIST] engine drive

Wed Aug 23 09:33:44 EDT 2017

Hi Hank,
Yes, shop is taking shape.  I am still working on setting it up
properly, but im nearly there now.  3phase is all installed and
machines working.  Just fitting cupboards and storage space.

I think I can get a diesel engine in the new sub.  Will be tight though.
