I am retrofitting 15 doublehung windows in a round tower. The tower windows are being reinstalled and wrapped with cedar trim that I am bending with steam and clamps. I am struggling with designing a proper drip cap for the 1×6 head trim. It seems that a Z shaped drip and a 82″ radius curve are incompatible. I am looking at possibly using something malleable like lead or rubber tape with flashing over it. Any help out there?

Lead works. Segmented and soldered copper works. Copper shrinked and stretched ( special tools) will work.
A simple pr. of duct / chimney pipe crimpers ( I prefer the 3 jaw over the 5 jaw) will shrink-a-late a flange to curve it.
Just as an example the top part is shrunk, the bottom concave is stretched.

Not quite the same, but this is possible with just those crimpers.

Very nice, but how did u strech it? Also drip flashing is usually z shaped so u would be streching or shrinking the middle leg of the z. any suggestions?
A stretcher is a tool for those who do mucho metal work. I do not own one, but they can be had at Harbor Freight and autobody supply places.
Simplest "Z" is use two pcs. and EL upside down over another EL. Slight radii can be "tweaked" by hand and hammer. Tight often requires segments and solder.Spheramid Enterprises Architectural Woodworks
