contactors and lugs for motorcycle

[David Cole <david.cole@medtronic.com>]

I was wondering if anyone on the list, or known by a lister, has a used
contactor for use as the main contactor in my motorcycle project.  I missed
out on George Tylinski's contactor blowout :) sale and was hoping those
were not the last on the planet.  Also, is there a store in the Silicon
Valley where I can get 2 gauge lugs/battery terminals.  I am going to try
the autoparts stores tonight, but I am not sure they will have what I need.
 Will the two-bolt crimp style work effectively?  Also, is there anyone in
the SF bay area with time and desire to demonstrate the fine art of
crimping to a novice?

To Mike Shipway and others interested in electric motorcycles.
The project remains the same:

81 Suzuki GS750 rolling chassis
Curtis 1209B controller (72V 400 amps)
GE 7" motor (6HP at 72V 85amp 6000 rpm)
Vicor 250W DC/DC converter (thanks George T)
Copper bus bars (.050x1" and 2 gauge cable between 78V of Optimas)
Some kind of contactor
Chain drive, no trans., 50 series chain (down from 60 series stock)
Shooting for low cg, <600 lbs wt (GVW is 1026, stock dry was 514)

Batteries are mounted, working on controller and DC/DC mounts...and
obtaining a good, reasonably priced contactor.
