melting brass padlocks
Hi all
Today I tried melting brass for the first time. I had some nice heavy brass padlocks around and so I dumped them into my 4" pipe crucible. After 2 hours and several pounds of charcoal the padlocks were orange but simply the brass did not flow. I did not took the steel pieces apart since I'm lazy and I expected to fish them out when the brass melted. Is padlock brass the yellow brass novices are cautioned against? If so, what would be a common scrap source for silicon bronze? Taps, hinges, fittings, something? regards, Mongke |

Hotter. More charcoal (more underneath?), lid, more air.

Mongke:
I can melt brass w/charcoal, but I have to do it on the first load of coals, adding more isn't enough. I agree with Tim. More air, better air flow - that's part of my problem adding more coals, the ash starts filling up. And a top. "mongke" wrote in message ... Hi all Today I tried melting brass for the first time.

I'm not sure what the difference in melting point is between the two, but I know that my old Yale padlock is bronze, not brass, and I would expect others to be as well -- at least those intended to be out in the weather and to take a beating.

Good Luck, DoN. Actually I can't say. I remember the packaging of at least one read "brass". All they are yellow tending to slight green. Some of them were outdoors and came in fine. regards, Mongke |
