Sub-roadbed Lap Joints

Written By: Alan - Jul• 27•13

All of the individual sub-roadbed sections have been trimmed to length so they lay end-to-end nicely. After a little jostling they laid in their proper positioning on the benchwork. A few joints required a little touch-up sanding to get the joint mating angles just right. It wasn’t a big deal. Where they were off it was only a small amount. Next is to glue in place the lap joint boards. The lap joint boards are cut from scraps of plywood leftover from the sub-roadbed cookie cutter operation. Every other section (even numbers) have lap joints on both ends. This will allow the odd numbered sections to fall into place. Screws from underneath will attach the odd numbered sections to the lap board. The odd numbered sections have a small bevel on the bottom of the joint cut to prevent interference from the dried glue bead of the lap board.

A disadvantage of doing a lot of gluing simultaneously is running out of clamping tools. Urk! I have three different projects all in a gluing stage at the same time. Bad planning on my part I suppose. Fortunately, it isn’t a race. I’ll glue a few lap joints every day I suppose.
