@Michael Pickett- did you notice the inner diameter of the pins being especially hard?
@ALB - it was definitely hardened compared to the rods. I tried a drill bit inside one of the pins that needed a little bit removed and it just skipped around and didn't remove much. That's when I went to the little grinding wheel.
I knew the outside surfaces of the pins were hard but wasn't sure about the insides. A carbide drill bit is probably what's needed to remove larger amounts of material. I guess even the grinding wheel took a little while?
