Sort of. Actually, I think you could do it without a tap. Give me a couple of minutes and I'll see what kind of sketch I can come up with.

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.
