forming bronze sheet..

I got the idea of covering two spots on my boat near the winches that get some wear.

So I purchased some bronze sheet material, about 0.030 inches thick or so.

Is there any known trick or method of forming a piece of sheet metal over curved surfaces?

Thanks,
gh

compound curve or just a bend? Auto body people use everything from sand bags with hammers to a machine called an "english wheel" for things like tanks for motor cycles or fenders.. A simple roller for flat curves can be found in any sheet metal shop.

There really is no such think as "bronze sheet metal" most likely depending on the color it is a metal called muntz metal which has a bronze color and was developed many years ago to clad ship bottoms. Today it is used mostly as a mirror finished decorative metal on elevator doors and inside of casinos. The alloy should be 60/40 with copper being the larger number.

I would recommend using Stainless Steel, rather than bronze, since bronze is softer and won't stand up to the wear as well. Harder metals are better for rubbing strakes, as they're less likely to get damaged. If a rubbing strake gets damaged, it can easily chafe or damage the lines rubbing it.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Look into hammer forming, it's a very quick and handy method for forming metal.
Easily learned (learn, not master) method that can be used to form anything from simple forms to very complex shapes.

Wow.
That really doesn't look like fun.
Funny how many videos you find of grown up men making suits of armor in their back yard.

Another option are these flexible stainless steel rubbing strakes that attach using an adhesive.

Thanks for the info everyone.
Since I already have the sheet metal, I guess I'll take a "whack" at it and see.
If it doesn't turn out, I will get some of the SS tape.

Please do the bronze sheet. It sounds nice and salty, and I doubt you'll have a big problem with the metal not "standing up to the wear."

You know, the rest of the deck is probably plastic, SD...

The rest of the deck isn't having a line rub against it constantly...
