Cutaway of the new Shopsmith PowerPro headstock
The new DVR (Digital Variable Reluctance) motor is neither the old fashioned AC or DC motor we have known forever. Rather, it is a magnetic based, computer controlled power plant that provides optimum torque and speeds for any operation.
In the past, many Shopsmith owners complained of the machine bogging down, or even stopping during heavy cuts. With the PowerPro, those days are gone. Torque is double the previous Mark V. I am able to power through cupped and twisted wood, knots, and the hardest woods with no slowing, burning or saw marks.
The PowerPro turns the Mark V into an excellent lathe: soft start, safety cut-out, slower speeds, and reversibility take the Shopsmith into a different league and should satisfy the most demanding turner.
The speed range is now 250-10,000 rpm, and the torque stays constant through all speeds. (All previous Mark Vs offer 750-5200 rpm.) PowerPro owners can now enjoy chatter free shaping at the high end, and safer turning and drilling at the low speeds.
The front push pad can be used with preset speeds, much like using the old system, or can be set for very fine detail; for example, I can choose the tool I am using, the hardness of the wood, the size of the cutter, the grit of the sandpaper, etc. While doing this may add a minute to the process, the results are so much better that it is well worth the time.
The new headstock is quieter, easy to learn, and FREE BONUS: can be converted to a 220v. system by simply changing out the plug on the end of the power cord! (Must then be plugged into 220v. outlet of course.)
This tool is a winner. The price may be beyond the reach of some, between $1300 and $1995; but considering the longevity of Shopsmith products, the nearly infamously great customer service, and the fact that a new Mark 7 sits right at $4000, I think the price is great. I also realized that not just my Mark V, but everything I attach to it benefits from having the PowerPro.
I am an independent contractor, not a Shopsmith employee. We currently host live webinars for Shopsmith, and get paid a commission from webinar sales . But I have made my reputation and my living by telling people the truth for the last quarter of a century.

Oh, did I mention, it is not made in Taiwan?
