Re: Babbit woes
You treat the steel caps the same way as the connecting rods. The parts are smaller so shrinkage affects them less. Tinning is a solder procedure that allows the babbitt to stick just like solder would. Folks that do a lot of soldering learn quickly that a proper tinning will allow for a complete bond in the process. The babbitt is just as sensitive as solder about contamination. If there is any contamination it just won't bond on it. The flux has to be right in the process too since it is a process of tinning.
Con rods & caps are smaller parts that can be heated & tinned more quickly and uniformly but a person has to use a procedure that will insure the uniformity. This includes heat and cleanliness. The parts have to be the right in the correct heat range and clean as a whistle.
