As for the Tormach, I recognize it as a well engineered machine, also note that they do not have a gearbox on the head so it's somewhat less heavy than a typical IH style.
As this is my first conversion I've often wondered if I'm trying to solve a non-issue by counter-balancing the head.

Jay and David,
Here is what I did on my RF-45 for the counterbalance: http://ImageEvent.com/tppjr/rf45dove...scounterweight
Working out pretty good. I did swap out the gas spring for a 150lb unit instead of the 200. I just don't think that my head is as heavy as the IH one. I have not sent the 200 spring back to McMaster Carr if either of you or anyone else is interested.
Let me know if you have any questions.
