Prior to joining discussion group, I visited posts on powering Atlas turnout frogs. Frog metal is not solderable. #8's not a problem as Atlas provides a solderable tab outside the gauge. #6's have doughnut tab molded to frog casting. I tried one contributor's clever solution, namely, inserting a 1-72 brass screw into the "doughnut hole." I couldn't make this work until I found my Kadee 1-72 tap set (never before used). Following instructions, I threaded the hole. Screwed in the brass screw, hooked drop around it, tightened, tested for electrical continuity: success! Also, Atlas sells a pair of inexpensive parts: 200001 screws and 200002 busbars. Call, these parts aren't in the catalog. They work well but bar can't be easily installed if turnout is already fastened in place, as a gap in the tie web must be widened. Best done at workbench prior to turnout installation.
