Do you pre-bend rail for hand laid track curves? if so how do you do it without getting kinks? My sad story : About 2 years ago I soldered together 3 lengths of code 70 rail & Gooed it to hand laid ties on a 180 degree 24" radius curve. Looked great at first. Now thermal expansion/contraction loosened the goo in many places & I lost gauge. Against my better judgement I sawcut gaps & added rail joiners to provide for thermal movement, but the rail "went straight" at each gap/joiner & there is no way I can get the kink out of the joint. I am thinking I should have pre-curved the rail somehow. Maybe even to a SMALLER radius than its final in-track radius?? (I dragged each rail over a table edge before laying but I would guess I only got about a 6 foot radius that way).
