Looks Great ! I have a question about welding / brazing frame . Was told never electric weld a CROMO frame . The metal will crack later . True or Tale ? Noticed British Bikes are brazed .

Billions of tig welded chromo frames still in service after 20, 30, 40 years of service, suggests that is a tale.
The frame of Vacillating is hi ten, but have done some frame mods on cromo also with no issues.
I'm Working up to building a modern klunker from scratch.

That is a good looking bike. Looking forward to your first ride report. The design does have the possibility of being a giant spring. Love your artistic seat post support. Very nice. Carrying that artistic theme through to your rear drop outs was a great touch. Keep up the cool work.

A steel frame builder told me that tig localizes the heat of welding very well and works very well on heat treated alloy steels. Stick and other forms of welding heated a much larger area causing the steel to lose its heat temper wherever it got too hot. This weakened the joints greatly causing failure. Brazing occurs at a much lower temperature and does not effect the heat treatment processes for hi strength heat treated alloy steels. American manufacturers used mild steel with no heat treatment process for strength to speak of. Thus Schwinn and other manufacturers electric butt welded their frames with no loss of strength to the designs because heat treatment was not being used as a strength component.
 
First test ride had the bars feeling a little too low.
Added Electra bars and leather saddle, made it much nicer.
Also got some green onto the fenders and chain guard.

Looks awesome. The stem I’m sending will give you some height without lifting it too much. Does the frame feel solid?

That stem will definitely help.
It feels surprisingly solid given the lack of a seat tube. I had a sprung seat first, so couldn't feel the frame. I know it's going to be somewhat springy
 
I like your fenders and chain guard a lot. I think the bike looks better with them on it. Your seat is far enough back that most of the weight will be on the down turned seat stays and not that long straight top tube. This will help keep it from being too springy. If it does prove to be too springy then maybe a small strut tube could be installed between the top tube and the bottom tube. I really like where you have gone with this design and hope it works out the way it is.

I got in a good test ride this afternoon. It is quite sturdy. It is not going to be a daily rider, so I don't foresee any issues with flex.
