Uberti pock mark in frame

[lone pine]

just got this Whitneyville from taylor's. didn't find this until I was cleaning up the frame with a toothpick. it was filled so didn't see it until I picked at it. looks like a flaw in exactly the wrong place. it's at 2 o'clock position in the pic.

Although it may be bothersome to you I don't see where it has any effect on the gun's function. It will be hidden by the cylinder and no one will see it. For-getta-bout-it and enjoy the new revolver.

Are you going to send it back? It's a casting inclusion usually found internally when magnafluxed or X-ray-ed. I've only encountered it once in a single shot 45 cal barrel of 4140 alloy. These percussion gun frames are usually made of 8620 alloy.
I doubt it will ever cause trouble mechanically but it sure would bug me if it were mine.

Haa!!! Like this one?

I'm working on this one right now!!! There's absolutely nothing to worry about. It's a "break through" from machining the hand channel.

No need to "send it back"!!! Lol

what causes it mike?

If it were mine, I would send it back. You never know that sometime in the future you might want to sell it and that might cause a problem with the buyer.

Just machining into an area that's thin anyway and breaking through. No harm no foul . . . definitely no structural harm. I see it all the time.

OMG !!

OMG !!

So Mike, if you were selling a pistol that had a casting void, would you disclose it?

 

[AlexB]

So the frame is cast and then cnc machined?

No, no need to. It will work just perfect and if it's a conversion, will handle +p loads just fine.

It's not a "casting void", it's a machining "breakthrough".

Yup

Yes, they are investment cast (lost wax method in ceramic molds) and then milled/shape'er cut to spec.
Original Colt frames were forged into billets then milled/shaped , soft fit (assembled ), with files, case hardened and final fit with stones and emery cloth.
There is always some amount of warpage when case hardening is employed necessitating the hard final fit.

If they were machined from solid the price would be horrific.

No, the pock mark is indicative of a minor casting flaw that was milled into and this one has what looks like a small crack emanating from it.
None of my revolvers have them.
It's not a danger but looks terrible and was possibly the reason it was filled.

Filled with what ?!
You actually think they went back and "almost" filled it in ?!

You mean because it doesn't look like this ( as it should) it's "no good"?!

This is a Pietta Navy frame.

Pure BS.

It could have just been left over slag, or mill filings filling it but was commenting on what the original post said of it being filled and found when picking at the pock.
The issue to the owner is that it was there in the first place not wither or not it was purposely filled to cover it up.
As to filler type,oh I don't know, perhaps a bit of JB weld and some dark stain.

Well they are largely milled/shaped from solid stock but this is an investment casting rather than the original forged billet.
The investment cast allows very precise dimension tolerances negating the need for many milling and shaping operations of the past.
The dimension specs of the internal chimney apparently are a challenge for even investment casting in some instances.

sure think it's a handy place to collect more fouling.
