Home shop power for a big machine - Thanks for the input

There is no mystery to hydraulics. Like anything else, it can be fixed with a little investigation and common sense.

What I would avoid like the plague are machines with a lot of
hydraulics, like the Mazak they converted to EMC at Roland Freistad's shop.
It is a reliable machine, but if something in the hydraulics broke, it
could get quite expensive to fix it. The machines with the simplest
tool changers would be much more desirable. Anything with a "spindle
drive" would be a plus, as opposed to something with just a massive
3-phase motor and a contactor. The Mazak mentioned above uses a huge DC
brush motor, probably would make a good traction motor for an electric car!

The Tree is well thought of, and I think they are of the simple=better
sort. I know several people have done successful retrofits of them.
