Can anyone help me with an idiots guide on how to calculate the radius of a curve required when rolling flat bar on edge (before bending it on the flat) to form a compound bend hoop?
I've done it before with plant pot stands but fluked guestimating the radius needed when rolling on edge.
I scored a big mother bowl the other day & I want to make a compound bevel hoop for it to sit in + some legs + handles to turn it into an off the ground fire bowl. I know with the plant pot the angle of the pot is constant & flat, whereas the bowl is curved, but I'm not going to worry about that in this instance.
I don't really mind if the calculations aren't bang on & only get me nearly there & there's a bit of trial & error using short sections for practice - I just don't want to start completely blind & waste a full 6m length on practice runs.
I reckon the hoop will be somewhere around 2/3 or 3/4 of the way up.
I don't have CAD and am a bit dim so please bare that in mind!
Cheers in advance.
