Default Re: babbit tolerance? .000?

Steve Ross USED to have a most excellent web site of "Rebuilding the Model A engine the KRW way." His original site is gone but exists in words only at http://www.antiqueautoranch.com/mont...n/babbitt.html

In this article he cites the Ford prescription for babbit.

Quote:
That neither the block nor jigs be heated for cast iron components prior to the Babbitt pour. They had metalurgical proof that the Babbitt had the best chemical and physical composition if this procedure was followed. Ford Babbitt was composed of 3 metals, Tin, Antimony and copper.
Unfortunately the Steve Ross article does not specify the percentages - but he had a separate web page which DID cite the Ford blueprint numbers, and compared it to Babbitt available today. And unfortunately this is no longer available online - somewhere I have the page printed off (the wisdom of hard copy) but try to find?
