Re: King Pin Problem
Purdy,
I don't think I would mess with a machine slot in a very hardened kingpin, it is too critical. I would return the kingpins to Snyder's. It would probably have to be done with grinding. A few years ago I had a machine shop attempt to make a later style kingpin slot into a rounded one to use some round early retaining bolts I had to be correct for my 28 coupe. To make a long story short, the machine shop fellow chucked up the first kingpin in his milling machine and bingo, the extremely hard kingpin snapped his 9/16" milling bit. The bit was not a fragile small bit. He wasn't too happy to loose an expensive milling bit. The kingpins are made of really, really hard steel or treated to be extremely hard.
