I was quite surprised that the thread worked straight off the print (M2.5) A couple of cruel enlargements: 499_031055_310000000.jpg 499_031056_260000000.jpg I couldn't ask for better electrical continuity, even with a resin key, as it showed 0.1 Ohm on my multimeter. I'm going to be concentrating on the fiddle yard over the next year or so, which I'm hoping to be PCB sleepers with rail soldered directly to it (although I did have to gasp at the price rise in PCB sleepers). So all this, for me, is going to take a back seat for the time being. But I'm glad it worked. posted: 3 Dec 2018 16 ...
