Source for drum to repair CVA Mountain rifle

I'm just going from old memories here but I seem to recall that the mountain rifle had half of it's diameter threaded across the face of the breech plug and that part of the drum was milled off to make it flush with the face of the plug. I recall this caused some consternation back in the day with owners trying to remove the breechplug not knowing they had to remove the drum first.
Probably the only source would be to have one made. Not a difficult part for someone with a small lathe.

Call Track of the Wolf; they will be more than glad to help you, and they are very knowledgeable.

Their number is (763) 633-2500.

Go with what Entropy said, I used to deal exclusively with a fellow named Greg, he was very helpful and knowledgeable.

Ease several thread taps or bolts in to get the correct thread size. Order new blank threaded drum. Screw in drum. Mark where hammer will hit nipple. Take drum out, drill and tap for nipple. If you need to file, grind or mill flat, do so at appropriate time. Done dozens of these. Most new ones are 3/8-16 or a metric "close to". Keep it all tight.

THR member frontier gander recently posted a photo essay about his CVA drum replacement procedure:--->>> http://castboolits.gunloads.com/showthread.php?376358-CVA-Drum-replacement

Apparently there's a replacement drum available that's already drilled for a nipple [but not tapped] and another that isn't drilled at all.
With one, a person would need to drill & tap their own nipple hole, and with the other a person would need to take measures to properly align the nipple hole with the hammer and also thread it, and snug the drum up to the barrel as necessary.

There is a jig available I believe from Track as well that greatly helps with drilling the hole for the nipple.

The place that had bought out all of the remaining CVA sidelock parts was Deer Creek Products, Waldron, Indiana.--->>> http://www.deercreekproducts.net
But folks say that their phone is often busy and can't contact them.
They can also be sent a message from their web page or direct to their email:--->>> [email protected]
It's probably a long shot anyway.

I still think the mountain rifle had a different drum arrangement than other cva percussion rifles. Easy to check just shine a light in the hole for the drum while looking down the bore. You should be able to see the face of the breechplug. If it is flat across it then a standard type drum will work. If there is a half round slot across it with threads then you will have to have a replacement made.

I checked their web site. If they have a drum they do not show it.

Deer Creek may have some CVA parts that are not listed on their website.
I mentioned that they would need to be asked either on the phone or by sending a message.
I really don't know if they still have the stockpile that they used to.

Yup, this.

There was some part that I needed for a CVA/ASM Remington a few years back... Wasnt listed on the site at the time, but decided "what the hell?" and picked up the phone... As I recall it took a few tries to get through even then, but when I finally they had the part and had it shipped out by the time I got off the phone...

That was a few years back mind you, so, yeah, theres that. Shrugs.. Keep trying is all I can say... Maybe they are still around, who knows? And maybe they have what ya need.. again, who knows. I do recall that whoever the girl was that answered the phone really seemed to know her stuff...

FWIW, at some point in time Deer Creek was said to have taken over the Douglas Barrel Company and their original rifling machine and were making different rifles/barrels/guns with it using the name WRW, Wildness Rifle Works.
Deer Creek reportedly made a close copy of the CVA Mountain Rifle named a Plains Rifle, and USA barrels for them that they made themselves.

According to gizamo:

"Picked this up today. Had to do a bit of research. At first the gun looks like a CVA Mountain gun. But it isn't...

It is a Wilderness Rifle Works Plains Rifle. WRW's made their own barrels on the old Douglas Co. equipment. American made gun and not an import.....

I'm trying to sort through the history of the company, so anyone willing to share a little of that knowledge would be most helpful."


"frontiergander

Deer Creek and WRW are one in the same. I'm not sure which came first. My understanding is that WRW bought out some of Hatfields equipment, including the barrel making equip from the old Douglas Co.

Hoping someone will chime in that knows the order of things...

Need a really long drill to drill the drum?? Who ever told you this is fulla crap, you install the drum, mark the outside, mark the nipple, remove and drill. Track sells a fixture for this purpose.

Snidely70431 was probably referring to the CVA advertisement that has been posted many times which states that some of the later CVA sidelocks having the patented integral drum and breech plug were originally manufactured by drilling
the drum's communication hole through the muzzle which means using a long drill.
The ad clearly makes that statement.
If the Mountain Rifle were designed that way, which I'm not saying that it is, then if the drum were replaced with a new one that was exactly the same, then the new communication hole could also need to be drilled through the muzzle to properly line up the new communication hole.
There was speculation based on the new design and information in the ad.
CVA would probably never release any of those identical parts since they've always instructed people to send their newer patented design sidelock guns back to the company for drum repair or replacement.
There can be difficulties with installing original parts "if" the Mountain Rifle were made that way.



frontier gander posted this photo on facebook, of the inside of the breech after the new replacement drum was installed on his Mountain Stalker.
It shows where the powder will make contact with the new drum stem inside the breech.
The old threads from the original longer threaded drum stem can be seen down inside the bottom of the breech/powder chamber.
If the replacement drum stem wasn't shorter, then replacing the drum and lining up the new communication hole could be more problematic.
View the original thread to see how much longer the original drum stem was compared to the replacement.--->>> http://castboolits.gunloads.com/showthread.php?376358-CVA-Drum-replacement
As a matter of fact, that breech plug of the Mountain Stalker might be the new patented design, but the replacement part isn't.
I can't tell for sure but it sort of looks that way.
However, the older production Mountain Rifle may or may not have the same design as the Mountain Stalker.

My point was for the average guy this would be great way to ruin a barrel. Seems like a lot of trouble for a basicly simple operation. The factory had specialty tooling to do this simple job without tearing up the inside of the barrel. Thanks Articap for the CVA ad that describes how they did it. I have run across several production guns that were breeched like that, it is very close to a Palmer breech. I have the fixture and the machinery to do this job, if the original poster would like it done he can PM me and we can discuss it further.

Arcticap thanks for posting that it really refreshed my memory. You will find that this is the way that the CVA mountain rifle was breached and the drum mounted. Drilling the plug from the muzzle would be an easy task with a simple sleeved drill bit but making the same for one job would be a bit pricey and as jackrabbit said really not necessary. If he already has the fixture the OP would be well served in having him help out.
