Thanks Michael and Perry,
After some investigation today we determined we just couldn=E2=80=99t get en=
ough travel with the current rod length on the slave. We mocked up a longer r=
od and everything functioned well, so my buddy Greg Wold (who says hi Michae=
l) who was helping me has some spares that he can match up and send to me.=20=
