I wonder if any of the other digi labs leads are comparable? We have fabratek and a few other brands. We got a bit obsessed with trainer type gear for electronics and physics 'this what that got young people interested back when' display. if there are any list member with a small turret lathe that would be nice to make pins with. pretty labor intensive. Better would be small Brown and Sharpe screw machine would make buckets of them once you got the machine all set up to make the run. Or cnc machine ( I never ran one of those) --- or as mentioned casting some. I will look and see is we need any pins. Ed#. In a message dated 7/19/2016 11:30:10 P.M.

Have I done the math right on that? mount the wire, and optionally to shorten the overall length of the pin and wire attachment to .65" from .75". (Or maybe just slot the pin's fat end, solder in the wire, and call it good.) I also thought about using a taper reamer to create molds and perhaps casting with solder around the fluxed wire. (Casting brass or bronze seemed to require more heat than I could generate easily.) (For some reason that I've forgotten over the years, my eBay search for suitable pins looks for "42107" and "42279". Never gotten any results for it, though.) Vince
