Dear sheet metal gurus...
I'm sure there's a formula for taking the diameter of a pipe coupled with the angle cut that will give you the arc needed for cutting sheet metal out so it'll be right when rolled into a tube ...
I'm pretty sure it's a curve, of some kind ... but I can't for the life of me work out how to get the right shape ... cutting it straight doesn't work, i end up with an Ogee kinda shape when it's curled. Got plenty of posterboard for figuring this out, thankfully!
Any ideas?
