Babbitt metal

[George D]

I believe from reading online that the original ford babbitt formula was 86% tin 7% copper 7% antimony. I have the chance to purchase some babbitt bars that are 91% tin 4.5% copper 4.5 antimony, it's trade name is Adament and its made by the Magnolia Metals company. Has anyone ever used this? Is the mixture suitable for Model A engines? Thanks for any thoughts in advance.

How much? You really need a lot to do a motor and there would be significant waste for doing a motor. So is it enough to do an engine? What do you expect from the engine? If you are building a touring engine for tens of thousands of miles it might not give you the life you want. I believe it would be a softer metal as the copper and anitmony give the babbitt more strength to handle the pounding in an engine.

To do babbitt right you need a large pot as a small pot will change ratios of metals more due to oxydation. There are a lot of considerations to pouring babbitt I will not get into.
