As others have mentioned the spindle bore is going to be important for you since you want to thread tubes and cut off stock. Short is better on a lathe because longer things flex more and any errors are magnified. If your spindle bore is too small to fit your stock through you are going to be workin...

I agree with the other post .065 is the minimum wall thickness I would consider. Others have had good luck using a muffler pipe as a rifle silencer tube but I personally think that is flirting with danger. the 316 stainless is a good choice but 304 will work well as well. If weight is a big concern ...

Great post James. I have a follow up question though. How do you set your tool height? You mention setting your tool .001 above center so the work does not try to climb over your tool. The only way I know to set tool height is by eye balling it or lining it up with a center in the tail stock. There ...

It sounds pretty good, not super quiet but comfortable to shoot with out ears. Does the porting cut down on velocity much? Have you chronographed it yet? Thanks. Ranb I don't think they are going to hurt velocity much. The first port is 5.5 inches from the breech. I put them so far out to give the ...

Thanks for recommending Photo Bucket L1A1Rocker, that worked much better. Here is the video, it also has some footage of a 22LR screw on can I made.

There is a lot of controversy over rather or not you can thread the barrel on a CX4. Something to do with import laws I think. I suspect that is why there is not much info on suppressing them. I think they have potential to be a good host. Does the bolt on the CX4 have anything to delay its movement...

The Camp 45 is done. I ended up using the smaller cocking knob, in part because the thought of it hitting me in the head bothered me and it did not clear the EOTech. Here she is. http://www.hunt101.com/data/500/medium/Camp_45_1.JPG It sounds pretty good, not super quiet but comfortable to shoot with...

I think most ammo will stay subsonic, of course there will be some that might crack but as a rule 22s stay subsonic in barrels <5 inches without ports. The only advantages I see to taking the barrel out is to reduce "stacking" errors and perhaps for a shorter, more rigid, work piece depend...

L1A1Rocker keep these post coming. I have thought about making a suppressed MKII myself. They are a ton of fun. Keep us posted on how you blend the seam between the tube and receiver. This is one step I could never quite figure out in my mind. I have heard that Ruger bores are very much out of line ...

correct me if I'm wrong since I've just got started myself but you can't just send your tube off for engraving. you have to be present while they are doing it and if they dont get done that day you have to take it with you. you cannot leave it there overnight. If you are going to be there then neve...

Is the bore of a barrel blank measured from land to land or groove to groove? If it is groove to groove, as I suspect it is but really don't know you will need to consider the land as well. Using a barrel blank is a really good idea. If nothing else you could get one a bit undersized and ream or dri...

I am waiting on the tube to get back from the engraver, should be any day now, I hope. Anyhow the baffles do strike a resemblance to Doug's and I give him full credit for "inspiring" me to put the steps in. That said conical baffles have been around for a long time and I do not feel that I...

There is no standard for the threads on the free float tubes. IIRC Yankee Hill uses something like 1.85 X30 TPI Olympic is slightly coarser. Now using a full length tube for an integral 22 or 9mm AR15 upper could be a fun DIY project for a fellow with limited tools. 9mm might get kinda warm though :D

Since you said some of your design goals are to make it compact and light I think you will have better luck with Ks or stepped cones like others have mentioned. Sure you can make one just as quiet with fender washers and spacers but you are going to have to make it bigger and heavier to do it. With ...

I think cutting stainless with a countersink is going to prove difficult. Try using the compound and a carbide boring bar. This page used to have a Silencer Test Results tab on the welcome page that had dimensions for several commercial cans but the link is dead right now. 12 inches is longer than m...

Aluminum is not the best choice for a 223 can. Think .065 stainless or steel. Your tube will probably work just fine, I just think there are better choices. If you are confident you can get everything perfectly concentric the minimum bore size I would recommend is .265 near the muzzle. With a can 12...

I do need to add that the warlock was new compared to the other suppressors and it was cold outside (around 30 degrees). We will try them all in a couple of weeks when it warms up. Sonic crack could have had something to do with it. I was shooting a SIG Mosquito the other day with a home made can a...

I was going to refer you to Orion Arms but now they have a big red banner saying they can not do registered silencer tubes due to state law :( http://orion-arms.com/new/content/view/39/116/ You may want to call around to local machine shops and see if any of them have a CNC dot engraver or other equ...

I don't have any info on when they are going to hit the market again but I have the opinion that they will be worth waiting for. The originals are great and the new ones are being made with higher grade materials and on CNC machines.

Mtdew's post are correct. On the face of a K baffle, by the bullet hole, there is a scoop (known as a slanted sidewall) this scoop redirects gas across the bullet hole creating turbulence and resistance to all the gas forcing its way through that hole. That redirected gas needs a place to go. That i...

Cheaper is to go to the local steel yard get a piece of AR500. 1/2" will take 50 BMG at 100yards, the thinner stuff will work for pistol/slower rifles Thats great but why not say that in another thread, rather than one asking for a members goods. No need to s--t on Kilowatt for making money. N...

I stand corrected 12-18 inches POI shift is broke. Hopefully they will choose to just make you a new can with your SN on it. It could prove to be easier and cheaper for everyone involved than troubleshooting your can. The 7.62SD is a great can you will be thrilled with it if the bugs get worked out ...

Got a pic? I would be leery of fixing what is not broke. From what I understand of AAC's manufacturing technique, from post on this site, is that they EDM the bullet hole pasage. Since you are not getting baffle strikes there is the possibility that the hole is in line with the bore and mount but th...

Why go through the trouble when a ruger or P22 works? OK G&R I am not sure if that is a real question or if you are stirring the pot but the reason I am interested in one is because I like the feel of a full sized frame, it is already threaded, very accurate, you can see the sights over the can...

Okay that makes a bit more sense I was thinking of the general mechanics of how the lock up works. I can see where there is a lot of room for variations for the same mechanism from one gun type to another.

Interesting.
