Regarding shim stock for hinges or flexures: In the event that C&H sells out of the shim stock that Jim has posted info on, it can be obtained from McMaster Carr Supply (630 833 0300): (MC, VISA, by UPS) In rolls of 0.005" x 6" x 50": stock number 9502K14 alloy 302 Stainless Steel $13.64 " " 9504K18 half-hard temper brass 5.63 " " 9020K41 spring temper phosphor bronze 10.95 Other materials are available in thicknesses from 0.001". I use the 0.002" brass for the box flexure for the new seismometer. Difficulties with the stainless are that it is almost unsolderable; if you epoxy the hinges, rough up the stainless with 600 grit emory. I use the office paper cutter to cut it into narrow strips.
