#2 babbitt?

[Soundguy]

Any use for this? I may be able to get leftovers from a project at work, they are pouring a bearing in a big rock crusher. I can probably get the leftover bars, kettle and large 'spill' pieces if I can use it.

Feels hard. Will ring if you clang bars together.

Thanks

I use babbit to harden my lead. My uncle was friends with someone that made bearing for railroad cars and they were made from babbit material. He collected the shaving from when the board the center for the shaft. Works great.Just don't use to much because it will make some hard bullets.

Yes!!!! Save it for your self or send it to me!! A few pounds of that would last a while.

It looks like this could be 89% tin, 7.5% antimony, and 3.5% copper.

Any problems with that copper if I use this to harden straight lead?

Looks like 20:1 would be easy to make.. Even something near Lyman #2

[Soundguy]

Anyone got an idea on a ratio of this to straight lead for a given hardness?

Thanks

Copper is a good lead tougher. It works via dislocation hardening.

I would simply use it at 2% per a full lead pot

I use babbitt to alloy lead. Some I know the alloy of others is scrap melted out of journals so I don't know exactly what it is. The #2 having that much tin will be very nice to add to wheel weights or pure. Copper isn't going to be an issue.

Thanks guys. They are pouring 2 sets of huge pillow block bearings, I see plenty of drip scrap, and stuff that ran into the clay overflow stops. There are still a couple ingots left and a half quart pot.. I can probably get all of it..

Like the others have said, its good stuff. I would jump on that opportunity!

What references I've seen seem to show some variation in content, even for a specific grade of Babbitt alloy. Still, for the tin in #2, that variation is only a couple percent around 90% (with the balance being Cu and Sb), so treating it like 90% tin is very close to being spot on.

So yeah, that's a nice score.

Get all that you can. The stuff is mostly tin and no lead. When I worked at the sawmill I used it to make guides for the circular gang saw. I also found a bar or two in the back of my truck on days that we had deliveries.

Straight, it makes some mighty hard boolits, and they will be lighter than a coww boolit. It's been a number of years since I left the sawmill, and had taken the Babbitt and melted it into one of those cast iron pans that look like corn ears. I still have a few, and every now and again I'll add some to my coww.

Cool!

I had some similar babbitt, mixed up a homemade batch of Lyman#2. (Then traded off the rifle I was going to use it in, some poor planning somewhere in there.)

Lucky guy.

Get every bit of it you can.

Alloy it out to get the copper between 0.25-0.5%

[popper]

Alloy with pure to get 2% tin - 4# pure to 0.1# of #2. Basically tin, very small trace of Sb & Cu < 0.02%. Still worth getting all you can.

There ya go soundguy!!!

[Soundguy]

Thanks for the ideas guys!

You're not too far from me if you get more than you can handle.....

I just alloyed 0.5lbs with 4lbs of Monotype tonight, to get a 17.5% tin, 17.5% antimony alloy, that I can work down with soft lead to get 2%/2% for softnose bullets, or 5%/5% for Lyman #2. We use it in wire form at work to spray-babbitt parts, and the wire leftovers that are too short to feed through the gun come to me at the end of a babbitt job.

[Soundguy]

Nice!

I ended up getting a 1# bar plus some muffin tin pours. Mechanic put it away for me. I'll get it next time I get down to the shop yard.
