Creative uses for bearings in the workshop

[Pete O]

To save the risk of outer races shattering when used as wheels, you could turn up some steel 'tyres' out of suitable round stock.
A couple of the larger ones might be a good starting point for a swinging gantry; a large tube with arm attached, rotating around a somewhat smaller diameter tube welded to one of your shed posts; swing it over your lathe and mill- good for changing lathe chucks, lifting that dividing head you know you're going to buy, etc...
