ATM 3 Wormgears and only 1 Worm

[cnebark@ix.netcom.com (Chris & Elizabeth Barker)]

Hi All,

    In my forays into the local San Jose surplus stores I have picked 
up several wormgears. One purchase was a goldmine of parts for $8.00.  
I got a larger 12v dc motor, a speed controller, a 120 tooth wormgear 
and a bunch of shafts and collars. All part of casing that had been 
dropped and damaged.
    My problem is that I need the worms for some other of the 
wormgears. Does anyone know of a place that I might be able to find 
them? Worms seem to be a hard item to find surplus.
    My "Machinery's Handbook has about 20 pages or so on specs of worms 
and wormgears. Should I not put much faith finding any that match?
    I appreciate your thoughts.
