Hi Freesbank...
What did you do to try and get more info on this mill?
What do you mean when you say...
"basically all I get is a "referral to the specs",no warranty or any other explanation."
Did you call or e-mail to get more detailed info on this mill?
As far as the motors go, there is a difference when comparing AC to DC motors. They have very different torque/speed curves. While the MD003 mill is rated at 1/2 hp, it is an AC motor. It's speed is also gear selectable so the rpms of the motor continuously stay within the torque/speed curves optimum range. The X3's speed is electronically variable which can put you at either end of a torque/speed curve where there is not as much power available. That is why it comes with two gear selectable speed ranges. The designers are trying to keep the rpms as close as possible to the middle of the T/S curve where the power is greater. If you are operating outside of the mid range speed with a DC motor, you are not getting the power you think you are getting as stated by the rated HP value. Here is a good page that describes it well...

As for additional info about the mill, why don't you call? I would be happy to give you any info you need.
I always do my best to give people as many details as I can. If you think the site needs more info, please let me know and I will be happy to add it. It is good to get some feed back.
There is a warranty on the machines. The factory gives 12 months for defects and workmanship. (I guess I could add that as well)
Thanks,
Pat
