Both the preceding are excellent points. So how about having a screw,
nut and insulating washer for the hole in the board, loop a #22 partly
stripped wire around the board hole's screw and nut and tighten
tightly. Then wrap the copper on the other end of the #22 wire around
the partially inserted post screw, put lots of tension on it, and screw
it tightly?
