Dad was SOOO concerned that there wasn't any way they weren't going to go rhombus and kept trying to over-engineer the project (my husband wasn't so certain, either!) but I stuck to my guns and followed the plans I'd "modified" to my specs -- 92" uprights (so as not to actually wedge against the ceiling), with 3/4" washers plus lock washers and plain old hex nuts in a 1" wide hole countersunk to 1/2" depth, 1x10 shelves and my brother just happened to have salvaged massive amounts of 1/4" all-thread that Dad cut to 12" lengths for us.
I decided to start my own vintage rental company, with farm tables being the main rental item. There was just one problem, I couldn’t afford to buy twenty farm tables… Which led me to my only option, I’d have to build them, except that again I didn’t know a thing about building or power tools nor did I know anyone that I felt comfortable asking to teach me. But, I figured if I could pass the CPA exam, I could figure out how to build a table on my own and learn how to use power tools.
I had shop classes in school which was a little helpful, but covered an assortment of skills. Mechanical drawing, leather craft, woodworking and other items but not in depth on any of these. I learned (and am still learning) by doing and trial and error. I watch a LOT of videos, look at others work (on here) and read a lot of articles but mostly by doing. The biggest skill builder, I have found, is the basic box. From that I learned cutting skills, measuring, fitting and squaring and I expanded from there. I wish I could take some classes and study under a mentor but that is not possible for me. Most important part of woodworking (I have found) is just to have fun with it, and, for me, a great stress relief.
Break down plywood Following the cutting diagram, crosscut plywood along the line marked “first cut”. Take the smaller of the two rip 3/4″ plywood according to diagram and cut list. For safety and easier handling, use a circular saw with a good quality blade (following a straight edge guide for a straight cut) for first cross-cut on plywood. If you are not confident in your circular saw’s ability to cut straight lines with no tear out, leave yourself 1/4″ of extra material (there is enough extra material in a 4′ x 8′ sheet of plywood to do this) and make your final cuts on the table saw.
