I started with Mianne benchwork for my 12 x 23 layout, here's where I'm at now. I'm working in my final track plan, but a torn rotator cuff has slowed work without help.
No it won't. Pretty sure this will prevent that issue from ever happening. It's glued with PL3 adhesive to the I-beam and top (after this picture obviously) and screws through the top deck go into the 3/4" plywood pieces to secure it to the bench top. I can sit on it and it doesn't move at all. Earthquake? Maybe. Gravity? No problem.I would cantilever some supports for that overhanging section. Over time, it will develop a sag from temp and humidity changes, and gravity.
