here's mine. the cut is actually too deep. the little pin is already in as far as it will go about 3/4 down the profile. The stocker leaves about 3-4mm of pin travel even at the deep setting.

After seeing what the jest of a custom ground pin looks like, I chucked my belt sander in the bench vise with a worn, fine belt.

Just between the front roller of the sander, and the flat "Work" area of the sander there's a gap. That gap was big enough for me to hold the fuel pin at the right angle, and press the pin into the belt. The result is the belt wraps around the pin nicely.

This allowed me to have a more uniform surface as compared to grinding with a Dremel and such. (I don't have a working Dremel so that made that pretty easy. LOL!)

The worn, fine belt was not so aggressive that it posed a problem. In fact, it allows one to take some time doing it. This in turn allows one to see where they're at.

Holding the pin just so, you can easily roll it about it's axis and come up with a nice, uniform face across its breadth. In fact, as you roll the pin, you can get heavy as you go to one side. This allowed me to have the right side more aggressive as compared to the left side.

Again, the worn, fine belt provides a nice, next to polished surface.


Took about 15 minutes. :D

I'd like to see a pic of a bullydog or ol smokey pin sitting next to a stock pin. It would give me and others a much better idea on what profile should be made. Anyone have or able to take a pic like this?
