Bruce, I also notice in your video you have a white box that will vary the power output, but also has a digital reading that shows current draw...is that an off the shelf purchase product? Or something you made up your self?
Something I bought from Ebay awhile back. I really like it , gives the amps , watts, usage, 5 different functions as I recall...about $10-12 , when I get home I can find the exact one for you. its as handy as a pressure gauge imho.
here you go

Just spotted the YouTube video called (Ben D12)

Thanks Bruce! That bullet nose shape on the crank pin certainly does not hurt, I like this feature for cleaning and lube.
Also see the link to the digital electronic unit, (I got one ordered) thank you!
