I have an old 3" trackball with a trackball mount and I would like to use a router to hide the mount, add atrwork and make it flat. Super basic, I know. I believe Andy made this an obsolete process with the trackball he sells, but I need to use what I already have. The template I'm looking for wasn't just a big hole cut out, there was an angle to it that was specific to the Happ trackballs. Does anyone have it or know if people came up with something better since I last looked at this. There might have even been one on the CD that came with Saints book, but I have no clue where that CD is. The search function turns up old threads with dead links. Sorry if this is a necro question, but I'm finally going to build a CP instead of buying the wood prebuilt.
