Hi guys. Good news (I think).

I happened upon my Grandad's ancient hand bench grinder today. It has a built in 10 to 1 gearbox, and I reckon could be "adapted" for other applications...

Here's a photo of one (not mine) disassembled:

And here's a cut-away of the real-deal Vortex supercharger gearbox:

Now it might be a bit of a leap to turn a 60+ year old tool into a precision gear-box, but it might just be a goer for an output shaft speed in the 50k rpm mark.

BTW. there are plenty of cheap examples on ebay. Search for "antique bench grinder" or "hand bench grinder"
