I recently started a 4/8 layout after many years of interest and having a few locos and a bunch of rolling stock put away. So I made the bench work, put on some 1/2 in plywood and added 2 in. foam board. Laid my track on foam roadbed, did some neat scenery etc. now I’ve realized that I have a problem not having a long enough drill bit to put my feeder wires through to solder the track. Am I going to have to tear it all apart and start over with the track and roadbed just on the plywood? Any ideas are much appreciated
