This thread is here at a good time for me.
A few months ago I bought a used 40+ year old Craftsman bandsaw on a moveable stand at a yard sale.
Took it home, cleaned it up and used it a few times.
It was OK for cutting small things - limited to 6 inch throat - but seemed to be underpowered and bogged down on attempting to resaw thicker stock.
Thought about replacing the bands and discovered nobody has any stock replacement parts for it.
So I sold it at our latest yard sale and chalked the small loss to research.
One thing I did see in my research was ceramic blocks instead of ball bearings guides.
Can anyone speak to that - is one significantly better than the other?
