We don't have a stove either. But when I was a kid, we could have used it in the out house, in the winter. We have been using the No. 35 torch, 45,000 BTU's . Cutting torches, have no place in babbitt bearing work. We Have used that for over 50 years. I thank the one now is the third new one.

Herm, thanks for posting these photos of your rod pouring setup. How do you pour in the babbit and what speed does the rod rotate at?

We pour with a Ladle with a snout, of varying lengths.

It runs at about 1,200 R. P. M's.

Thanks for that Herm.

We sell an aluminium drive spider here that we have to do some machining on to fit a particular application. The supplier is Italian but they shifted production to China a few years back. One of the things that took place in the shift was that they stopped using centrifugal casting. It was surprising to see how much porosity there was in the castings once they made that change. We stopped using those guys not long after.

It looks real interesting but I bet you have to be suited up well from flying Babbitt!

how do you get the babbitt into the bearing when pouring? Horizontal I might understand, but vertical not so much.
I know the voices aren't real but damn they have some good ideas! :shock:

Most casters are vertical, or you also having to over come gravity. They are also easier to set up, and work on.

For pouring babbitt, we use a Ladle with a 3, or 4 inch spout, to go inside the Die opening.

Suited up, yes indeed, Welder cap, long sleeve insulated shirt, and Face shield, babbitt is 950.

On the opening side, floors, walls, and ceiling, and me, if I get a little complacent.

With out the spinner, we couldn't pour all the thin wall cam bearings, bronze, and steel out of all the car brands, like Packards, Buicks, electrical bearings, Ect., as we have found that we can't pour cam bearings statically, as when they cool, the out side shell cools first, and then when the babbitt cools, as it shrinks to the inside center, and then breaks the tinning bond from the shells wall. You can even hear it clink, sound.

On Model T cam bearings, we drill 3 lines of 1/8th holes, one line down the center, and the other two lines just under the part lines. Doing this, after being spun, the babbitt is tight, like, or better then peening from centrifugal force, and made the babbitt very tight around all of the bearings edges. The anchor holes, and the original Broached grooves, are not there to hold in the babbitt, they are there to keep the babbitt from spinning, in use. The babbitt in static poured T bearings, are normally loose.

Also, when you take out old cam bearings, ( not Model T 's ) the bearing when new was a larger diameter, for crush. So, when you put a hot shell bearing in a spinner, it is at the diameter it was originally, and when you put in the babbitt, it pushes against the shell, and holds it there, until, it hardens. You don't want loose cam bearings.

OK, I have told you more then I know !

Herm.
