Fixing dents in Brass

Postby E7 » Wed Aug 05, 2020 10:36 am

Maybe turn a sow's ear into a silk purse? Burnishing would be one technique.
Anyone car to share their experience/experiences on this topic?

Just like auto body work. Gentle taps with a hammer against a dead-flat, smooth, heavy dolly. Be very careful not to expand the metal or excessively work-harden it. Putty or JB Weld is the finishing touch.

Rich, do you have a specific example that's vexing you? maybe a photo there of?

I'm sure many of us here have some legit experience with those kinds of repairs; dented brass, bent frames etc.
I certainly have.

I have a large anvil, :wink: :wink: And a smaller one in my shop on the table under the band saw.

I have made use of similar materials once "close enough" or in a few cases where I was going to probably cause more damage while fixing the dent.
What doesn’t kill you makes you stronger. It also gives you a lot of unhealthy coping mechanisms, trust issues, and a dark sense of humor.

Pete,

Just a topic that hopefully might be of value to someone. Maybe turn a buy with a caveat into a great deal. I am aware that metal can be streched from my hot rod days. I'm thinking burnishing might be the primary path to pursue. Maybe a source for tools?

Thanks!

I had an instructor waaay back that used to say: "You look like the kinda guy that could break an anvil." Kinda made you feel special. :mrgreen:

Burnishing works sometimes. Half-hard brass needs to be coaxed. The Lobaugh etched Challenger tender sides were dead soft, and always wrinkled. burnishing works on them. Hammering would destroy the rivets. But dead-soft brass does not make good models - maybe gaskets?
