I've tracked down a source for the machine screws - Apex Fasteners in Slough
(thanks to Jules Richardson for the lead). Now all I need to track down is
some nickel sheet or ribbon, NI200 alloy, 0.002 to 0.005 inch thickness
(0.05 to 0.125 mm).
Before anyone asks, I'm trying to hack together something similar to the
"hobby spot welder" on <http://www.hobbyspotwelders.com/>. I've got the
computer-grade capacitors (five rather large Cornell Dubilier DCMX series
120,000uF 25V caps, for a total of 600,000uF with a tolerance of -10%/+75%)
and just need the solder tags, screws and washers for them, and some
electrodes. Shame it's so hard to find #4 copper wire (then again I'm
probably not looking in the right place). The thickest I've found is 2.5mm
solid core copper.
