I cut and planed the 16 foot longerons. WOW! What a job. The picture of the longerons shows a couple of interesting things about my workshop. 1) I had to assemble my workbench made of three sections. A 60” x 36” maple old teacher's desk top, connected to a 48” x 36” section of a plywood shipping box and lastly a hollow core wooden door (maybe seven foot by 30 inches). Overall I ended up with 15' 6” of workbench. 2) The entire workbench sits on four saw horses made from 2x4's and pallet wood. And 3) cutting and sending 16 foot boards was its own unique issue because my workspace is only about 16 feet (as is visible in the above photo). So (the weather was cool but sunny) I put my table saw on 2x4 pieces in the driveway and cut toward the table saw (which leveling both so the boards landed flat was another issue). The finished but not mounted cherry mantle is also on the workbench.
