Nick, I did hook it up to my Wilcox & Gibbs sewing machine & after making a special pulley for the Bowman m101 it ran it just fine as seen below.
I tried to dead lift 9 lbs. but it was a no-go, 3.3 lbs. was all it would do. I noticed their claim was that it was powering a "crane" & would assume that there was more gear reduction with that outfit. I might try that challenge again soon.
