For what it's worth, those shoulder bolts from Coan are not the best. The broach of the internal hex, is iffy, at best. The last one I used (3rd unit), I made my own spacers, out of steel tubing (like I have since 1978). MUCH better fit, and no worries about stripping the internal hex for the next builder to hassle with.


Thanks for the info/experience.
Did you use 1/4 bolts instead of the shoulder bolts and drill the case to 5/16 and make a sleeve to fill the case and fit the 1/4" bolts nicely?
Is the Coan race tapped 1/4-28?

The shoulder bolts look like a good idea, but if the hardware is marginal, that defeats the improvement. Although I don't like the compression ferrels to fit smaller (i.e. 1/4") bolts into the case, I have never heard of any problems with them. And many standard bolt-in sprags use that method.
