   Convex or concave? Flat seamed or standing seam? Gimme some more info and I'll tell you how to do it (or how I would do it).

   Thank you!

   It'd be a (slight) concave, about 36" across at the base.  As for seam, I guess standing, but I'm open. (It's for my own house). Which would be easier?

   Concave is easier than convex. With 36" per side you need a seam in the center of each side. To do this without specialty tools, I would do a standing seam with a cap. You will need snips (red handles <$20), a pair of hand seamers (<$30), and a pair of downspout crimpers (<$30). Hopefully, you have access to some type of sheet metal brake. If not, you can do it all by hand, but it'll take a while longer.

   If you have a brake, make yourself enough copper roof edge to go around the perimeter. Use a standard piece of drip edge for a pattern. Plan B: purchase the roof edge at a roofing supply store. Plan C: Fabricate an el with one leg 3/4" and the other an inch, with the angle being 90 degrees. Install the drip edge or the el around the perimeter with copper nails.

   Layout a centerline on your roof planes. Use a piece of rosin paper or something similar to cut patterns. Lay them out on your copper sheet. For the center seams, bend up a flange at a right angle. Don't bend the hip side, but allow an inch to be hand turned later. Turn a lock 1/2" under on the bottoM (drip edge) side. Lock this onto the drip edge (or el) flange and line the side up with your centerline. Clamp it with some visegrips. The straight pan will be floating over the curved roof. Take the downspout crimps and gently crimp the side seam where it is furthest from the roof. Continue doing this until the pan lays down on the roof. Once it's snug, nail down some 1" x3" (+-) copper clips next to the seam and squeeze them tight to the seam.  Use your seamers and crimpers to hand form the hip seam.

   Repeat until you have your roof completed. Form enough "V" with each leg being 1" tall to cover all your seams. Squeeze theese over the seams. You'll have to figure out how to do the top yourself, but it's not to difficult with some clever snipping and folding.

   Oh yeah, when you get ready to install the second side of each hip, overbend the 1st side so it's down out of your way. Then stand them both up together.

   Good luck.

   I havent built one in awhile.  Is there a new format you guys use or any new tool that helps with the beginning stage?
