Walker Wedge Protrusion

[ClemBert]

I have a 2009 production Uberti Walker. I was curious to know from other Uberti Walker owners or experts as to the normal amount of wedge protrusion that should be expected. Specifically, from the picture, you can see my wedge protrudes approximately 0.150" beyond the frame. Is this typical or abnormal? On the opposite side (picture not available) the wedge is pushed in to the point were it is resting just about next to the wedge screw.

On my Pietta 1851 the wedge is about flush with the frame and therefore really doesn't protrude at all.

There is no standard for how far the wedge should protrude. The best indicator of 'correct' wedge position is 1) does it stay in place and 2) cylinder to forcing cone end gap of from 0.006" to 0.010". Some folks use even less end gap with good results.

Is your Walker wedge normal? The answer to that is what's the cylinder end gap?

From my measurement 0.002". That measurement with the hammer at half cock and the loading lever and piston used to push the cylinder back. This is an unfired Walker. It could be that when I get a chance to shoot it we may see a slight increase in that number.

I should also add that I am able to push the wedge back and forth with relatively little force. By pushing the wedge out with thumb pressure the gap becomes closer to 0.005". In this position the wedge spring's detent is a bit shy of hitting the frame.

Ideally I would like the wedge to be flush with the frame. As parts wear in from firing it well start to protrude more. As long as it is tight before it bottoms on the wedge screw your fine.

On my 2nd gen Walker that I have set the arbor length the wedge protrudes .125 from the frame. This has not changed in about 75 rounds.

Well, the reason I ask the question is that this unfired Walker could go back to Cabelas for an exchange if it was determined that it has a problem. I assume with a wedge replacement I could end up with a wider or narrower wedge. Something tells me that Uberti's wedges are not precision components.

There are many reasons to deem a revolver as defective and request an exchange. How far the wedge protrudes is not one of them.

Your end play sounds fine to me. I don't see anything wrong with the gun.

Make smoke!

That's what I wanted to hear from the experts!

A few extra wedges and springs are a good investment for any cap & ball gun. Get a mainspring, trigger/bolt spring and hand spring to have on hand. Italians seem to have a problem tempering springs.
