Re: [TCML] crowned pulleys

[Ed Phillips <evp@xxxxxxxxxxx>]

VDG's are high voltage and I think the moderator will tolerate some 
traffic on the subject.  Those things are available anywhere as part of 
rollers to go under things like stoves and you can probably pick up 
something locally for no more than the cost of buying that thing and 
having it shipped.  Those are mighty small for a VDG of any proportions 
and I'd think you'd want to roll your own.  A lathe is of course to be 
desired but even mounting the blank in a an electric drill and filing it 
as it spins will work pretty well.
