The wheels we had made kept the scrap down to 150mm each end but yep we welded ours together with a 5% inaccuracyIncidentally, you can't bend a circle with those machines. You can bend a spring like spiral, or you can bend two half circles and weld them together, as the first and last 4 inches or so, are scrap.
I note you are in York. When I worked in a street furniture factory, we used to get tube and angle rolled, quite tight, by a specialist in Leeds. Don't know if they are still going and can't remember their name. Probably easiest to let someone like that do it.
That is what I meant by spring like spiral. I make small rings out of 2.5mm gas welding rod, and use the "make it into a spring shape" method, by winding it round a 1" bar and cutting each coil with a cold chisel, then bending it back to form a circle, before brazing the ends together. Laid flat those rings are not perfect but good enough for my application. Only you can say if a spiral bent back to form a circle, would be near enough for your job.ive seen them bend a circle on flat bar hard and easy way with the overlap pulled out over the wheels
If you make the curve in one pass could you run a full length of bar through, end up with a long ‘spring’ shape, then cut that into the exact circles, saving any waste?The wheels we had made kept the scrap down to 150mm each end but yep we welded ours together with a 5% inaccuracy

Don't think the Leeds company we used was called "the angle ring co" "tube benders" springs to mind, but it is 18 years since I left the street furniture makers.
I'm struggling to follow your logic here, you asked for input on a machine that would cost over £4k with the accessories you are told you need. Then you have to develop the skills needed to use it properly, not an easy task and you could waste a lot of time and material getting it right - if indeed you can with the machines you listed. I don't know how much you would charge an hour for your services but I would suggest that £40 + vat for delivery on a job done right and ready to go is very reasonable for the weight of the box/pallet needed.thanks, I phoned a few people who offer the service but most want £40 plus vat for delivery which bumps the price up when your only having them done in small batches
