Wow. it feels great to be complimented by such talented modelers! Casey, I build my turnouts primarily because I can tailor them to fit a situation. In this case. a passing siding running along a backdrop out of easy reach required turnouts which would be within easy reach. By locating this one near the middle of a turnback curve at the end of a peninsula, it is easy to get at. I wanted it to match the curve of the mainline precisely, the outer route being a 30" radius, the inner only slightly smaller, thus the long points. BTW, there is no great amount of soldering involved, other than feeds, which all track requires anyway. Quite a bit of filing though! They don't have the fine details that some of the better commercial turnouts have, but they work great.
T, there is really no difference in building curved versus straight turnouts. I never work with a fixed frog #. After laying out the centerlines for each route and gluing down ties, I lay the stock rails first, filed to accept the points later. Then I file the frog points on two lengths of rail and use the NMRA gauge to locate where the point of the frog should be. When done this way it makes no difference what degree of radius you use. And you get nice flowing turnouts.
