Using the 4 side measurements and the alpha angle for patent image 18, I back fiddled the rest of the lengths and angles. I overlayed it on standard material. Angles other than alpha not shown but I have them if needed. I can plot any point and scale to any length.
Here it is overlayed on the actual patent image (in red). I expect the patent image has been distorted or it's not really 41 degrees but rather represents it.
Here's the same but scaled down and rotated to fit standard material. Long center length went from 103.5 down to 96.5. Easy to double the material but maybe not enough length. I'm only 5'6" but I believe I need 102" min. (76 + 24 +2) . Please correct me if this is wrong. Close up (macro) images of the 4 connecting ends on a HH would be very nice
On a grid with a 5' 6" stick dude.
How real is his angle?
