Babbit question from a new guy.

[Skytop b]

Hello, first post here. Just recently I have decided to get into casting (45 acp to start). I have access to a lot of free pure lead pipe, have ordered some tin ingots and startup equipment. My question is about this Babbit of unknown composition, I can get it free from where I work at. I think this is about 25#. Can anyone make sense of the stampings on the babbit here. Just thinking if I can figure out exactly what this is then maybe I can use it in the lead mix instead of buying tin, been unable to get wheel weights where I am at as well. Any help for a new guy would be much appreciated. I am also located in Canada. I checked this site to see if I could make sense of the numbers but no luck with my minimum knowledge so far.

Did you do a Google for Babbitt, w a, no. 4, 888? You might even find it if you use the site search.

Is there an image on the top, in the circle?

You could take it to the local scrapyard and have them shoot it with their x-ray gun. Might cost you a dozen doughnuts and a cup or two of coffee.

Anybody at work able to tell you what it is or has it been sitting around since Christ was a corporal?

We use it to pour cable sockets for sandline, I have been googling for hours here. Will keep reading and searching, thanks guys. Ahh, it does say No 4, I have been searching N64, this is what I found.

#4 Hardware Babbitt is a low melting point speed Babbitt consisting of approximately 85% Lead, 13% Antimony and 2% Tin. It's melting temperature is around 473F Degrees.

Not sure if this is a standard.

I'm no help on the alloy, I do know what a "rope socket" is.:bigsmyl2: Skytop Brewster has been seen in the oil patch also.

Ha, ha, I busted. I spent many years on a Skytop RR600. You are the first guy to get that [smilie=s:

I've spent most of my working life keeping either Rigs or Frac equipment running, familiar sight.

888 was a National Lead solder, a plumber's solder. Liquidus at 453F with a BHN of 13.3. I'm another oil field fellow, or rather I once was, back in the days of cable tool rigs. We were still using the old Bucyrus Eries back in the late 70s. "Since Christ was a corporal", haven't heard that one in awhile. Old WWII veteran friend of mine used to say it a lot. With a liquidus of 453 it would be about 40%Sn, 60%Pb. Not much help to you, could be babbitt because of the #4, don't think they'd be using plumber's solder for the job you mentioned, but if someone found out it's good enough, maybe so.

Cable sockets? They used to be zinc, in the logging industry. You should test it with HCL.

With it being "known" as Babbitt and labeled No. 4 I would say that is a good bet as to what it is. That 13% antimony would be a welcome ingredient and 2% tin is a good target for a pot. Only thing to do is melt it and check the melting temp and if you really want to use temp then turn off heat on melted pot and record temp every minute as it cools, you should see a plateau where the temp stays the same for a few minutes. That transition temp from liquid to solid is generally available for known alloys such as Babbitt.
