I'm about to make a sheet metal cap to cover an open cylinder. While I could just eyeball it and make random notches to prevent overlap when folding the flat sheet metal down over the sides of the cylinder, I'l bet there's some sort of formula to calculate just how many notches there should be and how many degrees of angle (or total length of notch cutouts) there shoudl be for no overlap and no gaps. While the "no gaps" isn't critical, I thought it would be nice to make it so the portions of the sheet metal that get folded over the top meet nicely on the sides.
I hope I've accurately described what I am making; just a round cap from flat sheet metal to go over and cover a cylinder, with the flaps folded down over the sides, to form a cup.
Is there a formula to get this just right, without a lot of trial and error?
Thanks,
Brian
