It really gorgeous... I do think it'll triangulate well with the seat pan and other bars.. a few gussets and it'll displace effectively..
I'd be more interested in how the stays deal with all those dimples.. from my understanding of the draft, it seems like there would be a great deal of torque going on down there at all times, I don't have experience with how they would perform because the wall structure in my mind is "compromised". I'm no used to building at this scale..
On a Harley that would be a fatigue point so it's a no no..
But it's a bike and not vibrating itself to death constantly also ..
Regardless I'm in awe... It's a beauty
After the rest of bars are there I'm sure you'll be able to even torque test it to see with the clearances u have going on .Thanks.
To be honest I've been so concerned about the strength up and down that I haven't really considered side to side forces. It seems like that is were there might be an issue with the dimpled tubes. Not sure, I'm not an engineer and am just building by best guess. True though that dimpling of tubes for clearance on factory frames are (always?) horizontal along the tube instead of vertical? Once I have the frame complete I plan to take some measurements and run the bike through a few cautious test rides. I'll remeasure to see where and if there is any movement and then if required plan additional reinforcements. The good thing is that there is plenty of room on the inside of the stays to add material. The bad thing, it could potentially be a very short test ride!
Love the flow of this bicycle it is unique for sure. Looks nimbleLatest progress, bending the side stays. Symmetry is hard! They ended up closer to each other than the image of the tubing in the bender would indicate... close enough anyway. I added a plug to one end, packed the tubes with sand, plugged the other end, and welded the tubes together. Then I ran the twin tubes through the bender. (Probably important to note that I made sure that the plugs didn't seal the ends completely. This prevented pressure from building up in the tubes as they were welded.)

Bottom end reinforcement. I'll weld this in place after cleaning up the previous welds.

Side stays in-process and in position. I plan to make some adjustments. The rear end of the side stays will be trimmed and the sides rotated a bit. The upper ends will be trimmed and tube extensions added to follow what will be the bottom edge of the seat. I'm also thinking of tapering the tube from 3/4" to 1/2" along that edge and shortening the seat length a bit. These are the handlebars that are the winning choice... so far.

WOW!!! What a curvy work of art!!!
It's so surreal it is sorta like a Salvador Dali build!
I think I have some like that in my parts pile...
