I’ve been out of the hobby for years, but at my wife’s urging, I’m back. I’ve decided to build a small layout from an MR track plan, and it seems just about ideal for the limited space I have available. The plan calls for a 'Sector Table—actually, two of them. I’m resigned to the fact that I’ll have to scratch-build them, but I’m just wondering if anyone has any practical experience with them, and if there’s an easy way to do it.
Sector tables, traversers and sector plates are quite common in the UK model railroading community. I can only recommend to post your question to a UK based forum, such as RMWeb
