Sorry for the delay. My machinist has a death in the family and got the flu. It delayed my parts for a bit.
So far:
Status:
2 atc bolts are complete. They are made from S7 tool steel. These were basically set up and trial pieces. I will probably give these away to someone.
1 trx bolt: machining complete, heated and quenched to spec.
All bolts are awaiting zinc plating. I got a company lined up for the zinc plating. I will be taking the bolts to them in the next day or so. I will take a pic or 2 tonight to show the progress. So far, they are shaping up very well. The hex head fits the socket very nicely. Also, a good tight clearance to the linkage bushings.
