Yes, I have done this several times. All three of my DW’s are very early ones that have the removable gas ring. The gas rings are available from Numrich, but they are hard to find on their website. They are stainless, but you wouldn’t know it to look at one. Getting the original one out can be very difficult, but since you are going to replace it anyway just use an EZ out to save a lot of time. You will have to trim the new one to the length you have calculated you need. Not having access to machining tools I had to do mine by hand. Once you have the length correct you just have to drop it in there, but in my experience the fit is very loose. You will have to use whatever means you’re comfortable with to tighten it up. Patience is an absolute necessity!

Thank You so very much for the response... seems like kinda what I thought.. is the fit Too Loose for Bearing Mount Loctite??

I am thinking loose is Not a big problem, except for possible parts loss on disassembly.. or??

Thanks again!!

Somebody post a pic of what you're talking about.  I'm not understanding a 'gas ring' reference  outside of an AR or semi auto shotgun.

Anything worth doing is worth doing well.

On older DW's the front of the cylinder had a Removeable (somewhat) section (the gas ring) against the Crane.

Later on the cylinder is one piece, and can be shimmed like all other of the type

Easily noted due to that "ring" on crane of Later models!!

I have a bunch of parts, I will look for a gas ring. It would be original so it won't require, trimming. I also have a large collection of cylinders and cylinder assemblies, many of them are porkchops. You could just replace the whole assembly or just the cylinder with gas ring. Keep your old star. I will check them for what might work. I AM the world's greatest procrastinator. so it might be a little time before I check. 🙄.

@Ole Dog

That would be all sorts of Too bad if you had a cylinder.. Save me fitting a cylinder...!!!

Appreciate Ya..

Been Shooting 38-44 Loads in this Pork Chop since??? IDK...Over 50 Years!!!!

Had some bit of time, so was gonna cure the Problem!!! Obviously I do Not Necessarily Procrastinate!!!!

If the gas ring fit is too loose the cylinder will turn around on it instead of carrying the ring with it as it’s supposed to. The gas ring will just sit in one place with the hot gasses burning at the same spot instead of distributing it around the entire ring as the cylinder turns. I’ll let the panel decide if that’s a problem or not.

Racepres, thanks for posting those pics & the explanation. I can see why the gas ring has been built into the front of the cylinder of most any revolver out there. I have heard previous mention of a removable gas ring on DW revolvers, but this is the first I've seen pics of one actually removed. Until today, I had presumed they were all cut into the face of the cylinder as part of the cylinder manufacturing process. 

Tonight, I looked at 4 of my early DW's, and I still can't see that the gas ring is a separate piece. Geez, I even looked at one of my Ruger Super Blackhawk's, that one looks pretty much like the DW's. I will admit that I'm not willing to try to pry one of them outta there on one of my DW's just yet... lol2 So I will have to assume they are all wearing separate bushings & just can't see 'em.

 Racepres, what are your 38-44 loads?  I haven't heard of this load so far.

Again..Only Early DW's have that replaceable gas ring. The way you tell is ...Looking at the Second Picture. That Donut machined as part of the Crane. Indicates a Cylinder that has the ring integral to the Cylinder. Note that the Crane in the First photo does Not have that Donut machined into the Crane.. just the "shaft" protruding.. passing thru the Removable gas ring. Donut=Later model without removable gas ring.

Edit; for Charger Fan, 38-44HD was a 38 Special revolver made by S&S on an N frame...Kinda Overkill!!! Intended for "Heavy" 38 Special loads before there was a 357 Magnum. Nothing more than ++P 38 Specials..Think 158gr at about 1200fps.. out of yer 38 Special!

@3ric; It probably is less than ideal to have the gas ring not be integral (or affixed to) the cylinder..but. being replaceable... I won't sweat that if it don't always rotate..

If the early 15-2s had a gas ring separate from the cylinder is it correct to assume that the earlier porkchops have the same separate gas rings? Being a porkchop fan I have a bunch of cylinder assemblies and parts for them.

Yes...I own one each, Pork Chop and Early 15-2 both utilize the Fire ring! I do own a later cylinder/crane assembly.. but alas, not the same ...as It incorporates the Donut integral to the Crane!!

Wanna Trade???

Edit; Just occurred to me... I now wonder if the crane and all can be replaced on the 15-2 successfully.... Won't solve my problem with the Pork Chop cylinder, but...I may yet learn something!!!

I would like to see a photo of the “problem” pork chop cylinder. Is the gas ring damaged? Worn to the point of having excess end play? In your first post you referenced needing to replace the gas ring on a 14-2 which is not a pork chop.

Yes, a later cylinder/crane assembly could probably be successfully fitted to an early 15-2, but there could be clearance issues; use caution.

The cylinder on the W12 and model 15 is not the same as the 14-1 and 15-1 which are the same as the early 14-2 and 15-2.

Welp... The Only Problem with the Pork Chop cylinder, is the Chambers are Not done well from the begining. Rough machining.

I have Never seen a Damaged Gas ring...But, as Noted...the Gas ring establishes Headspace..just like the front of an integral cylinder establishes headspace. Hence the gas ring needs to be replaced to establish proper Headspace. (this spare one is excessive)

Yes, this Pork Chop has the Same Cylinder as the Early 14-2, 15-2. I confused the issue, in that I do have a Later 14-2, 15-2 Cylinder and Crane.. and am now wondering if Crane and all may be a Replacement option...Only on the 15-2! Which BTW don't need it.. Obviously the crane won't work on the PorkChop!  Too Many Parts...But, None of the correct ones just now!! Not Insurmountable at all..

 

Edit; @3ric, I noticed you (and Others) have previously posted about Early Dans having Rough Chambers!! I do Not wish to "hone" my Cylinder...tho, I suspect a Proper Chamber Ream would have cured my Woes Long Ago!! I have Never intended this particular piece to undergo "stout" loadings...and so..The 38-44HD loadings have been perfectly satisfactory.

as an aside; I have Heard much about bullet jump and Accuracy...But own more than one Contender Barrel that put that completely to Rest!!

As does this Particular Pork Chop!

Yes, what are called 14 and 15 - 1s are not the same as 11,12,14,and 15 in many respects. Most noticeable is the front and rear sight differences. High Standard Mkii and mkiii are the same gun as the DW dash ones.

 The 11,12,14 and 15 have the shorter hammer fall too. That is because of the trigger has a little ledge for the return spring to rest on.

  Models 11 and 12 normally have a hand spring that wraps around the hand. That was changed to the hand with a slot in the back that the spring fit into
