Wished I could tell what was used to grind this but my machinist son-in-law did it for me. I waited almost a year to get it back, (he's quite a procrastinator). But I do remember him saying it was rather difficult due to the hardness of the material..........Rob

I just want to state that torque can vary depending on how much gunk(old loctite, etc) is on the bolts/nuts. I have a feeling that the subject is due for chastising.
