Very interesting. How the heck did you know the word Catenary?  huh shocked grin


Roughed in another nose rib then threw on a rough windshield shape just  for planning. I knew I'd have to "wing it" a little here but it's going to work out fine. I'll cut out a better version and use it to make a final rib that will set the shape of the top of the windscreen. I'll use 1/16" Lexan for the final windscreen.

Knowing me, I probably accidentally noticed a long strand of pearls hanging between two of my favorite things!  cheers

Here's another shot of the windscreen and one of the thigh rests. My kneecap is about where that line is by the axle. Once I'm on it, it's actually very comfortable. I'll have to be careful not to fall asleep.  grin

Mike, is your bike's snout short enough to comply with the regs?  There are limits on how long it can be in many rulebooks.

Yep,  a full inch.  I have to keep checking with my framing square because it looks so close.

Got the final windscreen shape done today. The silver surround shows the bed that the Lexan will sit on. The black is the view area.

Got the lower-mid body shape cut, mounted and "mated" to the upper shape (whew!). I cut and mounted one of the two middle side panels (the only two flat panels on the bike). Note that the body runs all the way up to just behind the forks and the belly will end at a vertical line just behind the front axle. Since the front fender can be an inch wider than the forks (each side) I can make it so it actually overlaps the front lower fairing. The air should have smooth going as it passes from the fender to the lower fairing. That's the theory anyhow.

Tomorrow, I'll be using the "Catenary ball chain technique" (thank you, Roy  grin) to determine the belly shape.

I really enjoy doing this. I call myself an "advanced tinkerer" so this kind of stuff is right up my alley.  cheers
