My Viel conversion hit a snag; my refrigerator died. This did not cancel the project, but did slow progress. While waiting, I continued doing research. I found references to two speed motors (1725/1140 rpm or 1725/830).
My only reservation with the Viel, or dry grinding in general, is the heat generated. Max's variable speed modification, as shown in his scissors sharpening video, seems just the ticket. In my case, as a home sharpener, speed is not a consideration. I believe having just a slower speed might solve my problem, although I have no direct experience to support that belief.
Pros and cons: If I can locate a slower speed motor which fits 115 volt, NEMA 48 frame, half inch shaft, and reversible; Replacement would be just a direct fit, except for the reversing switch. (The Penn State Industries variable speed motor requires modifying the mounting bracket and either boring out the pulley shaft or turning the motor shaft down to half inch in addition to wiring the switch.) I see three speed ranges listed, and am curious to know what the direct drive range would be.
I would have to have a machinist bore out the pulley. Could I do the bracket modification in my home shop?
Comments welcome.
