Nice saw. Looks easy enough to gear down or add a transmission to. I have a drill press of the same mfg. they sure built stuff to last back then.
A small lawn tractor trans might work and could be found for cheap $$$
A few more pics and yes I plugged it up and its way too fast. 32inch wheels means 32inch throat. Already had wasp in it.
Very Nice Saw . I noticed in the pics if you(have not already) move the belt too the small pulley on the motor it would cut the RPM in Half.tommie
