I use old English copper pennies for wishbone ball shims. Today I removed one that had been in for about a year. It had formed into multiple paper thin laminae!
The penny must be laminated
The type of penny and how I whack it into a concave shim.
Mark, have you been keeping it lubed? Although most any T would probably keep the ball very well lubed from the engine leaks. Dave
Yes, I lubricate on a regular basis. All those pieces were stuck together with grease when I removed them. I soaked them in gasoline to clean them up for the picture.
Mark, I believe Bob Bergstadt makes a preformed shim that fits that socket. You can also file the cap, and the socket too, if you remove the two studs. I pack mine with wheel bearing grease, and then squirt it with oil every now and then to keep everything going.
Langs sells a replacement socket but you have to take the engine pan off to rivet the new socket to the pan and may have to do some brasing to assure that the rivets don't leak. Major repair.
If you want to use shim, use a disk of high quality steel like 1045.
Is the ball worn undersize?
That's easy to fix. Mig weld extra metal and file it down.
No guys, I’m happy with how my penny shims work. Have done them like this for year. Just never saw a worn one like this before.
I think that's a good fix Mark, I'm more intrigued by the thought that the coin was struck from a laminated blank. ?!? Coin collectors out there shed any light ?
You'd kill a 1913 penny?
Well ... that one was not used. I buy them by the handful and “kill” the ones that have been worn down to the point where the dates are missing completely. Same thing with Buffalo nickels for block plugs.
