Default Re: Front axle king pin holes

I walked into a local machine shop (one man shop) and he had a Model A axle propped up in the Bridgeport. Recognizing the axle, I got into a conversation with the machinist and he says he does this infrequently, but perfectly (his words.)

"Doesn't sleeving it reduce the material in the axle eye and weaken the axle?"

"Somewhat - but there is some excess for strength - I do have to remove a bit more than is necessary to actually do the sleeve, but I have to use a sleeve thick enough to press in and then machine in place. I've never had anyone come back with an axle failure."

So it is done - not frequently - but perfectly.
