Bridgeport clone quill lever question

[Janderso]

Hey all,
Based on this pic, is there to be a spring and ball detent that follows the grooves?
The allen screw was missing but it just screams ball detent.
Thanks for your help.

Could just be drilled out for weight savings...

Shame on you!!

On the original bridgeport, yes. I'd assume the clone would be no different.

While I don't have first hand knowledge, it seems like those radiused grooves in the shaft indicate a ball ride in there so the handle can be moved to a more advantageous position... so on a guess (educated guess) I would say so... A spring is questionable as the ball just needs to be held by a set screw, but it could have a spring.

I guess the only way to know for sure is to see if there is a step in the hole to capture a ball. A groove like that wouldn't have to be rounded if its job were just to keep the lever hub from coming off. The torsional load is all borne by the cross pin, so there isn't much else to restrain other than axial movement.

Well shoot.
I don't see a relief for a ball.
The grooves line up with the lever arm fully engaged and when pulled out enough to pivot on the shaft.
If I install an allen screw it makes no sense. It has to move in and out
I really don't get it.
Maybe a relief was too much labor?
I'm going to find a ball and spring and give it a whirl. It appears to be a 3/16 radius according to my set.
What the heck

Is that a through hole?
Also curious about the angled radial lines in the bore. They look almost purposeful.

It should have a ball and spring if possible, otherwise, moving it would be a PITA if only a setscrew was used.

Yeah, it's meant to allow you to knock the handle to the side, disengaging the drive dogs. I'll grab you some pics of mine, though the ball and spring disappeared long before I got it and I've never got around to replacing.
