Reply to "Gargraves Track"

I don't trim on a curve at all. I will square it up at the next switch or well into a straight section. As the inside and center rails grow, I will start the next section on to the curve and go to the end and tap all rails back with a wood block, threading them into the ties of the peice before. I bend as I go against a jig for the curve, bending and screwing as I go and always tapping the rails back to keep the previous joints tight. When finished, none of the joints line up and this helps keep the curve from kinking. Each rail joint has 2 rails with no joint along side and this way it makes a smoother curve.
