Okay, my previous post didn't paint a decent picture,so a picture is worth a thousand words. Here is the gear in it's home.
Those two black parts are collars, that keep the gear where you want it. The builders turned down the bolt to make a stub shaft. It bolts through the side. BUT.... The shaft is supposed to be 0.5" diameter, and it's some bit bigger, each is different sized but all are too big.
I've got to resize the shaft bolts to fit correctly, and make the bushings to fit the 0.75" hole in the gear and the newly turned down 0.5" shaft.
Rework is a hoot!!! Or not, for small values of hoot. I'd rather have these uniform and not a custom one off job on each bolt. So, lathe work tonight! Alright!!
