I took the sheet of buffalo board that will go on top of the plywood, and proceeded to try and remember" high school geometry".
Armed with my tape measure, my trusty straight edge / compass ( a 6' piece of perforated metal strap) and a black Sharpie, I laid out the center of the turntable and the proper position for the roundhouse.
Then I cut out the opening. The hole in the plywood deck will be round.
There is a very good chance that all of the backdrop, fascia, benchwork and track will be done by the end of the year!
Ah, now I remember those high school debates on whether we'd ever use this"stuff" when we got out of school. I was one of the lucky ones who liked geometry & trig. Apparently you remembered as well! Happy Thanksgiving and be well.
Thanks Matt. Geometry was one of my favorite classes, and it was the last math I got good grades in. I roll my eyes when the younger generation says "why do I need to know that?" I was so, so at trig, and calc kicked my butt. Didn't help that it was at 8 AM my freshman year of college. Guess I wasn't supposed to be an engineer.
I had to work backwards from the roundhouse, by marking the centers of the back wall of each stall, and the door centers, then drawing a line through the marks. As you can see, I guessed wrong the first time out, and had to move the turntable over 5" to the point where the 3 lines intersected, which of course was the center. I don't remember learning that exact problem in class, but I would have liked geometry even more if it was in the textbook.
You may not be an "Engineer" but you definitely applied common sense to your layout.
