We have this one, works well, though I don’t use it much. Can’t see how you’d end up with eggs unless you’re changing the roller tension mid-roll, or the machine is unwinding it’s self or something.
Just roll several times increasing roller tension each time. Use a piece longer than the final circumference and trim down to size.
Alternatively I’ve had good results just pulling thinner rod around circular ply forms (or big dia tube) clamped to the table

I have this one
I think where I went wrong was cutting to the circumference of the circle, then bending. obviously the ends were straight. I welded the ends together and ground it down then rolled again, which made it rounder but I over compensated, expecting it to just all round out but it went a bit wonky. it should be ok for what I need, its just not as accurate as I would like.

just using a ring roller I bought off eBay for about £100. that might be where I went wrong...
