Not as much an issue as you might think. If you buy a motor with the same frame, they pretty much are a direct swap. Phase converters are even easier and not too expensive. Grizzly has a 3.5HP to 7 HP phase converter (240V 1PH to 240V 3PH) for under $220. http://www.grizzly.com/products/Static-Phase...

I would not be too concerned about the 3 phase; change out the motor(s) to single phase or even easier would be to get a phase converter.

What the heck is a smurf tube?

All, I came across a Wintersteiger ski tuner; double belt and side edger in Palmer Lake CO (North side of Colorado Springs). The belt grinder has been in storage for 3 years, but was working when taken out of service. Not wide enough for snowboards. Weighs about 450 lbs, so bring an engine hoist or ...

What design did you use on the press? What steel do have? I've been considering building a press (I'm in the Colorado Springs area).

Any pics you could send of what you have for sale?
Thanks
