What I was pondering is described in my very poor sketch below.
The idea is:
1/ Tap a 5/16 thread into the crankcase/rear cam bearing
2/ Insert and loctite a 5/16 normal length stud
3/ Turn up a 1.75" length of 5/8 AF hex bar threaded 5/16 female in both ends to be a joiner.
4/ Torque the hex "joiner" onto the stud
5/ Attach the bracket to the head and insert the long stud into the hex joiner
6/ Torque the long stud down to 5ftlb less than the hex joiner
The raionale is to provide a neat, repeatable set up where the crankcase doesn't just have a stud tapped into it with no clamping helping to support the metal around the stud.
Criticism and suggestions welcomed about everything except my draughtmanship!
