Thanks! Cool project you are doing!
I've filled tubes with sand and bent them with an oxy/acetylene torch over a wooden buck before. Not pretty or elegant.

Ever have an "oh CRAP" moment? Yep, scratched cornea. All better now. Bends and copes done, just down to fitting, tacking and welding. Great news is new hole saws at correct speed do a wonderful job at cope miters in the drill press with Harbor Freight tube notcher. 1600 RPM on a 1" Milwaukee bimetallic is golden. Blue chips are the goal so watch feed. No cleanup other than debur.
Have to say Blue Ox Lenox hole saws seem to cut better but are more fragile. But WTH do I know as this is my first CrMo rodeo. I do know when feed and speed are right, it cuts great and fast.
When chips turn blue, all is good. Put heat in swarf and the tool will stay cool.

We have a bicycle!!
Only have one front axle as these purchased parts are 416 stainless and required a redesign as I won't weld such a part due to stress and material. Sure, it could be done but the part is designed and purchased so use it as intended. I did one steering knuckle and it worked so the team will use the university machine shop to replicate.
I also fabricated the knuckles from A36 1/4" plate. Fun welds for a change.
The hardest was the rear triangle. Laid it out, jigged the dropouts and tacked it up. After welding, the wheel dropped in with NO cold setting of the spacing. 135mm on the money.
