Dumping the Banjo Bolt

[Kajo]

For all you classic automag RT people battling Banjo bolt leaks what do you think about just dumping the thing entirely from the system?

I can admire the theoretical design but it just doesn't work that well in practice.

Here is my idea:

1. Thread the rail hole that is currently there
2. Make a hollow stud with a stepped diameter that threads up and into the frame rail and valve
3. Have a threaded cap that seals the grip frame side of the assembly

The stepped and hollow stud would function pretty much like any asa 90 degree elbow in it's ability to transmit air without leaking. You might need some teflon tape but it should be more forgiving to body, rail, frame, inconsistencies than the banjo bolt.

You could mill a slot in the body and just tap right into the side of the valve like a typical valve. You'd have to use a solid thumbscrew or plug the banjo hole somehow.

This would work but I think it would require more engineering than a simple hollow stepped stud. For instance, it does not look like the existing air hole is simply a hole. It has some milled contours. Also, I'm sure they over-engineered the crap out of the valve, especially the SS one, but you are still putting more holes into a pressurized device which can lead to failure.

So you're thinking something like a two-piece system?

How would you tighten the hollow stud? I mean, what kind of wrench do you see using on it?

Take a look at this stud on mcmaster carr.

You would tighten it with an allen wrench.

Edit: Guess you can't link directly to pages on mcmaster. Go to the website and do a search for PN# 94358A120. You will see what I mean.
