Nipple?

[ken.clements]

Take a look at these and tell me what you think....The rifle is 3 months old, brand new out of the box. Shot 4 times.

The photos are so large I'm not sure what you trying to call attention to...is it the cap residue that's messed up the bluing...is it the apparent void in some of the threads of the nipple seat...is it a problem with the barrel...a bulge or something?

 

[walruskid1]

what am i looking for?

 

[ken.clements]

please take a look at how the nipple sits when its screwed in. (normal?)
there are also threads missing where the nipple screws in (normal?)It's like a piece is broken out at the top
The photo where you can see the square (I don't have a large enough metal ruler) is how much the barrel curves (sort of like an enlongated blunderbuss for lack of other terms). The barrel seems to wider at the breech and muzzle with 1/32 in the middle.(normal?)

 

[Poor Private]

That void in the nippel/cone threads you are seeing is the channel to the barrel. Fire/flash must somehow get to the powder in the chamber of the barrel from the nipple. Otherwise your weapon wont go BANG. :thumbsup:

 

[Trot]

Yeah, not good. Did the nipple fit like this as it came? Who is the manufacturer? Could be the nipple has been crossthreaded, the hole was improperly tapped or the nipple itself is threaded wrong, hard to tell which from the photo.

 

[roundball]

OR.....the nipple could be threaded and sealed just fine, particularly if there's no blowback occuring.
Depending on the sequence of steps in the snail's manufacturing process, maybe some sort of milling operation took place after the seat was drilled and tapped, and the slope simply falls away under one side of the nipple flange more than it needs to...dunno...but it does seem a little unnerving and if it was mine I know I'd have to get that corrected or make a floor lamp out of it.

As far as the barrel goes, its not uncommon for the breech area of a barrel to be larger/thicker/stronger where most of the pressure is, and then begin to taper down away

It looks like the nipple hole was drilled crooked and not to a right angle of the flat!

+1

the bolster is probably as it shoud be

when they drilled and tapped the hole for the nipple it wasnt secured (leveled) in the fixture

theres enough thread engaged it should not blow out but its still another sloppy mfg qc issue and will collect extra crud etc, maybe a nipple flash cup made from brass can be formed to fill the gap

 

[roundball]

Is the nipple / hammer alignment correct?

If it is, that might suggest that the nipple seat is drilled squarely/properly...otherwise, manufacturing and quality control would also have had to:

1) Realize the quality defect mistake in the nipple seat and ignoire it;
2) Then make more quality matters worse by bending the hammer to strike the nipple squarely.

 

[MSW]

while i'm certainly no machinist, i think RogueRiver got it in one- the nipple doesn't sit square; this can't be right.

i'd contact the manufacturer

How does the gun shoot? Are you getting blow back past the threads?
What make is the gun?

Thats there's a hole at the bottom...yes, i realize that. Oposite the hole there is a piece broken out of the threading (at the top of the hole)...this broken out piece is barely covered by the nipple itself.

Other than a nipple that is a bugger to remove...crud everywhere?
I don't have a face full if that is what you mean and I cant tell when I'm shooting.
The hammer stays down.
I won't be shooting this anymore untill the company says something...

Yes, I understand that....but the square is against the barrel at the breech AND the muzzle...its hollow in the middle.

"....The rifle is 3 months old, brand new out of the box. Shot 4 times."

It doesn't look so to me.

 

[napolean]

Is the gap between the barrel and straight edge consistant? If you leave the gun lay and move the straight edge to the oppisite side of the barrel, does it appear to have the same gap? What I'm gettin at is the barrel may not be perfectly straight. I've seen that on one new gun before.

PS. I know this is a .58 Musketoon from your other thread, but from where? Manufacturer?

[ken.clements]

it seems to be that way on all sides of the barrel...but it doesn't seem to constant or the same...more on one side than the otherI always thought a barrel would be thicker in the breech, slowly becoming thinner towards the breech, but evenly. This is not the fall.....I don't have the tools....wait a sec....I got a micro downstairs...I'll measure it...be right back nope...I can't measurs it exact enough to be any help....I'll see what the company says tommorrow
