Any number of pre WWII diy/home workshop books (perhaps only UK ones) go
into great about driving hobby shops from lineshafts, usually powered by old
lawn mower/motorbike engines.

One of my neighbours has a workshop behind the house, both built
around 1900. It's still powered by the original Crossley 6hp gas
engine, six foot flywheel and all. Couple of big lathes and a drill
in there, all running off flat belt lineshafts.
