Somebody wanted to see what they look like. Can’t remember what thread it was. A little rusty. Kim

It was me who asked about the shot peened crank. That lightening bore looks dangerously sharp. Is that a picture anomaly? Thanks. The grain looks a little different.

That’s how they are. This is a 73. 340 cast crank. Kim

That's why God made grinders...
