Hi everyone,
I wondered in anyone know where I might find some shop wheels I saw
once (and never again!) They are about 2" diameter, but the neat
feature of these is that they have a pedal which raises and lowers
them, so that when attached to a large bench or workstation, you can
drop them to stay in place, then use the pedal to raise them and move
the whole station..

I hope I have explained this well enough..I've done exaustive searches
on the net, and never seen one again..

Any help appreciated
Cheers
G
