Broaching Ends of Cylinders

You'll have to put the dimensions on the attached item, but what I'm seeing is a custom clevis. The top (round hole) is sized in distance to lock the clevis to the cylinder's base. The hex is far enough back to allow the other side of the clevis to butt up against the base of the cylinder's mounting while maintaining strength.

This would be a two-operation setup on a waterjet that could handle thick material. Or with a machining sponsor.


The threading option would replace the upper hole, and require rather more drilling out of holes.

Thanks so much!

Bimba and most other cylinder manufacturers offer hex mounting nuts. You could weld an adapter onto the nut then screw it onto the cylinder. Or use a taller nut with the same thread diameter/pitch.
