Do you have a steel supply near you, they usually have benders......Curt
Cranbrook Springer Forked BTR YD100 Replica Build (without fabrication)

'And I appreciate the info. I think leverage will be the key for sure. The 1” tube I cut off is roughy .077” thick. I’m guessing I can find something comparable at Home Depot."
Not.
Curt and Steve can correct me, but bicycle tubing is generally 4130 chromoly. As in aircraft frame tubing.
Home Depot it ain't.

Steve, gave you a good tip if you are unfamiliar with shaping steel tubing. Packing sand in the tubing and trapping it causes the out side of the bend to stretch while minimizing crush and collapse of the inner bend.
I don't know what your day job is. It takes a particular skill set to safely fabricate a bike frame. I Don't.
Consider your Night Rider, every frame joint is lugged and brazed. The tubing is chromoly steel. Just trying to keep you from breaking your neck Danny, if the Sporty doesn't first.
Regards,
Tom

Hmm that is a possibility. I need make sure of my angle but I bet they could knock that out in a couple mins or less
right the sportster is more of a worry, but point taken. Where can I find chromoly steel? There is a pipe place not far away, I will call them when I get a chance. Otherwise there’s a place about 45 minutes away I’m sure would probably have it.'And I appreciate the info. I think leverage will be the key for sure. The 1” tube I cut off is roughy .077” thick.

thanks tom
Remember Co Bappe's bike Vekst frame fabrication method? He drew a paper template to gage everything from.
Then again the Edison way works too.

Me? .083" Welding thin steel is a pain. Until you get your amps set right. Curt can counter me. My experience as a welder is quite limited. I repaired a lawn mower deck break with a flux core 110V.
At work using a gas shielded MIG is a total different cat. Practice a lot. blow outs in thin steel is common.

Bend? Check with a local muffler shop. If it is thin enough an electrical conduit bender might work.

My latest project
I’ve had this girls bike around for years. It was my older sisters, she got it new for Christmas in 1959, but she didn’t want it any more and told me to scrap it. I have better ideas for it ! I have a little China girl 2 stroke that I wasn’t using so I decided to build another board tracker...
