We are back from what was hopefully a busy and productive weekend. Let's see how it all turned out. Saturday: was as predicted. The rain came in, mid morning which did nothing to slow my progress. After watching a few informative videos on line regarding woodworking, I was off to the garage. I spent the morning setting up the shop and making inventory of Module Mk.IV. For this new lightweight version, the dimensions are the same as before, 48 inches long by 18 inches wide. The big difference is that the module is made up entirely of Birch Ply with just a simple flat top. The end plates are actually to FreeMo standards and are made from 3/4-inch ply, while the sides and inner stringers are 1/4-inch ply. Since the module is completely held together with furniture grade wood glue, the inside of the two 1/4-inch ply sides are routered 1/8-inch deep by 1/4-inch wide so the stringers lock in. It took some time to engineer this and I have documented everything as I have at least four more modules to build after this. By Saturday night I had this. The middle 1/4-inch stringers are 3-inches tall and will butt up against the 1/4-inch plywood table top. I need room for the folding legs. Sunday: More videos on woodworking, followed by more time in the garage building jigs that will be used in future construction. I started working on legs which are made from 3/4-inch ply cut 1.75 inches wide and 1/4-inch ply cut 2 inches wide to form a light weight but none warping L girder style leg. The legs are 46.5 inches long and when set up, will have the layout sit about 50 inches high, also FreeMo standards. "Wait, Jim! Your buddy and your current modules sit at 54 inches!" Never fear! At the end of the L leg is a 2-inch by 2-inch 3/4-inch square with a hole and T-Nut centered and glued to the bottom of the leg. This holds the adjusting bolt, but I have designed a small 4-inch adjuster leg to allow me to connect with Bill's modules. So Sunday I worked on engineering the legs. Everything is just dry fit now to leave room for adjustments and documentation. All in all, it's coming together better then I had expected. The rest of the day was spent with Ang and a nice quiet dinner and some visit time with my daughter and her boyfriend. So how about you? What did you get accomplished this past weekend? Let us know. We'll assemble again on Friday the 13th! Hmm, perfect for the month of October eh? Until then, stay safe, have a great work week and as always... High Greens!
