Standard disclaimer: DO NOT begin a suppresor project without first obtaining approvale from any and all state and Federal agencies: ATF Form 1 is required from the feds.
This is part 4 of my attempt to build an integral suppressor on a Mauser VZ-24.
In this section I'll cover making the Chamber Cap, Tube Support, and Muzzle Cap. I'll probably throw in some pics of some reciever work and the problem with the stock for good measure. Hope you enjoy.
First I'll start with a repeat pic of the barrel.
As you can see here the barrel has been cut down (18 in), tapered, and threaded over the chamber and at the muzzle.
Alright lets get to some of the fun stuff: Muzzle Cap
Sorry I didn't take any pics of the thread cutting process. I'm a novice at this and cutting threads can be pretty nerve racking. Taking ictures was the last thing on my mind!! But I did get some pics of the hollowing out process.
And some pics of the finished product
Next the Tube Support: This little guy has a very critical tolerance on the outside diameter. It keeps the tube from wabbleing around in relation to the barrel. It has to fit tight!! It screws onto the end of the barrel and is secured with a set screw.
No pics of turning it out (taking those pics got kinda borring after a while) but here are some pics of placing the set screw.
And for the sake of brevity here are a couple of pics of the almost finished Chamber Cap. It still needs a set screw but I cannot install that untill I have the barrel finally mounted to the reciever and the chamber finish cut.
And now a picture of a partial assembly alongside the tube.
As you can visualize here, after the barrel is mounted to the reciever the Chamber Cap will be screwed down flush with the reciever and be secured with a set screw. Over the barrel stainless steal wire mesh will be wrapped. The Tube Support will then be screwed onto the muzzel and secured with its set screw. The suppressor tube will then be slid down the assembly and screwed onto the Chamber Cap. (the tube is apx 8" longer than the barrel). Next a series of expansion chambers and baffels (shown in part 3) will be installed into the remander 8 inches of the tube and secured with the Muzzle Cap. I should also note that the Muzzle Cap will contain two baffles seperated by a small expansion chamber in an effort to capture all possible pre-curser pulse (see responces in part 1).
That's pretty much were I'm at with the suppressor itself. How about some pics of other things being done on the project?
The reciever: Since I was rebarreling anyway I decided to go ahead and do it right. I resurfaced bothe the inner and outer barrel matting shoulders on the reciever. The outer is easy to do as it is simbly placed in a jig and turned down on the lathe. The inner one is the real Bi***!! The mauser actually needs to be barrelled on the inner shoulder and there are no tools made to do this. You got to make it yourself!!! So here are some pics of resurfacing the innershoulder (thanks dad for your help as a model here)
A little lapping compound on the brass tool here
Screw onto reciever
And let her rip
Actully folks, go slow here. Take your time, use lots of compound, and check the shoulder often. This will take you a couple hours here but please Take your time. You really don't want to screw up the tool, or worse, the reciever.
Now we need to know how much to take off the barrel or the locking shoulder.
As I said in part 3, Measure twice cut once!!
Slight problem with the stock. Can you spot it?
Right!! You can't open the bolt!!!
Because of the extremely large diameter of the suppressor tube I had to have a custome stock made. I chose a Colberson Prone style from Elk Ridge. Unfortunatly the comb is way too close to the reciever and the bolt hits it. Now let me say here that the guy I spoke to at Elk Ridge is a 100% stand up fellow. We got a little confused when I ordered it but he was ready and willing to re-make the stock in a different configuration that would clear the bolt. Elk Ridge will stand behind their product and make sure the customer is 100% satisfied. After I looked around and thought on the problem I've decided to have a channel custome cut into the comb to accomodate the bolt. We'll see how it turns out.
Well I'm out of pictures now. Hope ya'll like what you've seen thus far. So what's left? 1. finish ream the chamber; 2. mount the suppressor hardware; 3. finish cut (on the lathe) the external suppressor hardware - to make it pretty; 4. hog out the barrel channel in the stock for the suppressor tube; 5. send off the stock for needed modification; 6. piller bed the action and tube; 7. guncoat all the metal in flat black.
Stay tuned, More to come. . . .
