The lathe features electronic variable speed - no loss of torque even at low rpms. That's what you see in that "box." The top is MDF, but is on top of steel stand. You can read the article in RodMaker to learn why it isn't going to warp.
There is no vibration from this lathe. Even with unbalanced turning stock, the 350lb gross weight tends to take care of any vibration I'd get from anything I could chuck in this unit.

No underneath support is needed - it's 5/16th inch steel. AC Motor, electronic variable speed. The control panel swivels so you can place it anywhere you want.

You need to check into the modern electronic variable speed AC systems - they are not your grandmother's window fan motor. This one is a "constant torque" motor and will provide the full rated torque at any speed above 10% of the minimum. It is one reason for the great expense of these lathes but for my purposes it's well worth the price.

0-4500 is the norm. 220V is standard with most, but for a few dollars extra they will ship them ready to go on 110V. To convert back to 220V is as simple as just taking out a "jumper." The motor on mine is a 2HP. I'm guessing that the motor and speed control system added about $800 to $900 to the price of this lathe. Bought separately they could be over $1000, but you can shop around. Plenty of companies supply these type motors and systems now. The one on my lathe is a Japanese system. I can dig out the manual and get contact information if you want, but you can surely source your own from any number of places.
