The Marks adapter (spud shaft) is well proven, and some with a lot more torque than Frank is using. For me... Rule no. 1: Try to use parts that have been proven in real service, then shop around in that pool to pick a solution.
The tricky little thing is exactly what steel to use and the heat treating has to be just right. That's the proprietary part for all of these adapter makers.
I like that 'the forum member' is doing this, and wish him all the luck with it. But I don't want to do the development qualification (HALT failure testing) for him.
Needs to find a lab with a bigger machine than this.
Then how to shock test? + thermal.
There's a lot of work left to do.
