Matt: I use to build my switches many years ago, they also turned out nice but developed prpblems later. I am unable to advise you on your question as I am not using DCC but would like to ask you a few questions. <br />What code of rail are you using? I was building in code 100, the problem that I ran into is with the throw rods and rails, they were just too stiff, bad enought on number 6's but very bad on number 4's. They would work good for a while but would let go at the throw bar. Someone told me that if I cut the throw rails just past the frog and put in a rail joiner this would allow the rails to swivle. Unfortunately this would wear and would loosen the rail too much, would loose electrical contact and eventually with loosening would cause derailments. I managed to pick up some good commercial switches at a swap meet for very reasonable price and have used, and re used them numerous times. I would like to get back at building my own again as I am expanding a small area. <br />Do you cut the rail between the frog and the throw bars? If you do what do you use to keep the swivel tight and constant current? I understand that the thinner the rail, code 83 or 70 you have less problems. <br />What book were you using? <br /> <br />Jim: many thanks for the site, am contemplating using DCC and this will sure help. <br /> <br />Many thanks to both.. Ron... <br /> <br /> <br />
