I’ve inherited a railroad bell that is about 100 years old. I am disassembling it to have it taken in for blasting. However, I ran into a problem with removing the clapper. It appears to be attached to a bolt that is threaded through the top of the bell (see pics). There was a nut on top of the bell that came off with minimal persuasion. I tried soaking the bolt with PB blaster, but my problem is that I don’t know how to apply torque to the clapper to remove it. Can anyone tell me the best way to go about this?
I would like to have the clapper removed so that it can be blasted separately (and the inside of the bell will probably have better blasting results too).
I would not sand blast a brass or bronze bell. Iron bells yes but the blasts will make ruff surface. The iron yoke and cradle can be sand blasted.
I ended up not attempting to remove the clapper because I was afraid of damaging the threading on the bronze bell. I had the bronze bell with the clapper attached blasted with glass beads which restored the color and removed most of the rust stains. I expect it will develop the greenish patina over time.
For the cradle, yoke, and other parts I had those sandblasted and then powdercoated a flat black. The end result was beautiful. Total cost for the project was about $400.
Go on YouTube and check out you using Candle Wax. It worked for me I heated up the bolt and dripped the wax in the top 2 or 3 time and when the wax was still wet. I try again and it worked like Magic.
