take your time , twenty small shot and it will work
Hi Dale - I've built 4 copper boilers. It's lots of fun.
1) Make sure you know what annealed copper feels like. I did not for my first boiler, so I re-made it.
2) a soft faced hammer is what you want. When copper is annealed, you want to just suggest to it where it should go; a hammer with a hard face will mark copper really easily.
You'll figure it out. Once I figured out #1 above, everything else was easy.

I like to wrap the face of the hammer with soft leather. It will need to be replaced once in awhile but it does a very good job of protecting the copper from hammer damage. You will feel the copper harden as you work it so re-soften the metal often to avoid cracks. A quench in water with a little sulfuric acid will clean all the black off the copper. If the copper is not clean you will work the dirt into the metal.
