Because I mixed different curve radius sections in a large curve, I can't close that curve up with my straight-run section unless I add a One-Inch section of 031 curve to the end of the last 10 inch 031 curve section.
With a piece of curved track this short, it will be impossible to use straight steel track pins on each side. So, I am going to go with single pieces of copper wire, to go totally through each of the three rails of the one-inch piece and jut out one-half inch on each end of the rails.
Does anybody know what gauge of copper wire I need to buy to closely approximate the circumference of 031 steel pins?
And, I see online that I can buy a short coil of copper for pretty cheap, but some of the ads say it is "half-hardened copper."
What does this mean please? And, should I use the half-hardened?
