MJ, I don't think that electric arc welding was as sophisticated and reliable in the WW2 era as it is today.  I recall reading an account of the Siege of Corrigedor in 1942 where the statement was made was that toward the end of the siege they were running out of welding gases to repair the guns from bomb and artillery damage and had to rely only on electric welding with the implication that arc welding was inferior to gas welding.

A friend and I just finished pouring bearings in a 100 LG. The journals need to be cleaned to bare metal, all rust, dirt and oil removed. Tinned with 50/50 solder. We preheated the journals to about 400F and the instructions for the babbit was 685F for pour. The top caps were poured too cold and shrunk and had to be repoured. I must have read the LG book a 100 times before we tried the pour. It is not real hard to do but not easy either. Good luck on your pour.

How are you going to get the correct temp to tin and pour the babbit without burning off the powdercoat? The bearings should have been poured first.

I'm game to listen . Tell us a story. Please?

As a boyscout I never got to meet a blacksmith all through Eagle Scout. Sad really.  No one to teach or inspire metal work. 

Das, check out what's available here in Virginia for the youth thru the "Blue Ridge Mountains Council"

J. C. used to be a welder until he was paralyzed in car wreck and is now confined to a wheel chair, so the medication is probably necessary and all he has is time on his hands. Thanks, Jerry
