I see, keep us posted how it works. I met a guy once at an antique engine fair who used JB Weld for a main bearing in a hit and miss engine and said it was doing fine.
Here’s what I did. I put JB weld in the axle hole at both ends. I then wrapped the king pin with one layer of wax paper and inserted it into the axle. I put in the locking pin and tightened it. The next day I slid the king pin out and peeled away the wax paper and checked the fit. It was tight. Took it for a road run and seems fine so far. We’ll see how long it lasts. Thanks for all the help.
