Ive got a pipe bender Langy if you want to give it a go , it may work !
If you do find someone with a ring roller near us , do let me know I usually get Angle Ring Co to do mine !
Try tartan engineering they have extensive ring rolling equipment and are reasonably priced 01628810119 they're just outside High Wycombe. I will hopefully be getting an industrial ring roller in a couple of weeks which might come with tooling for 2" round tube.
Steve, Wayne has a ring roller that would do that. Do you talk to him?
Wayne at ODDrods. Blackpopracings' mate in Feltham/Heathrow area?
I knew of a place in Perivale. .
Not many miles from you..
Never did get there name but try a Google search for tube bending in Perivale.
They are or were just behind the old hover building.
How shallow a bend do you need.
I have a ratchet very heavy tube bender. Not yr normal type.
Has formas and dies etc.
