...Not many pictures but I had to post. Thanks for the knowledge!
9" OAL, 1.61 average overall OD, small end is 1.59, 1.5" ID, 1st cone is integrated and welded to the 2.5" x .080 thick 1.5" od blast chamber and is un-clipped . The next 5 are clipped and the last one is not. No spacers are used, all baffles are welded to the tube. It ended up weighing 1lb 11oz on my eBay postal scale. Overall this has been my favorite build, the electro etch numbers look almost factory! (minus the paint shop to conceal the serial, I don't know why we do that)
Battle Scars!!:(((
I've only shot it with subsonic 300 Blackout, it's quieter than my 10" K can....maybe I need to try another K baffle can? According to my wife, it's quieter than my Gamo Whisper.

That looks great!
Tell me about your etch process, did you buy a mask or print your own? I etch my stuff too, but looking for a better mask method. Yours looks good.

One of my navy buddy's wife has a vinyl graphics printer. She prints up the stencils on scrap material for me.

Re: 308 316 Stainless Clipped Cone Sealed build
That is a very nice build sir! I like the photo spread also.
You had me in stitches seeing your battle scars welcome to the club.
A wonderful mentor commented on my enthusiasm about machining saying
"one day your going to be cut up and bleeding wondering why you got into this work".
You build showed a wide array of skills that were nicely done.Did you line up your ports or did
you time it differently.I suspect you will be pleased with its sound.

Hmm. Does she want to make a little extra $$? I need stencils for a couple different items at the moment... PM me if you wantatc250r18 wrote:One of my navy buddy's wife has a vinyl graphics printer. She prints up the stencils on scrap material for me.
Re: 308 316 Stainless Clipped Cone Sealed build
How did you etch it? I understand the vinyl but what process and how long did it take?
Re: 308 316 Stainless Clipped Cone Sealed build
I use a 50/50 blend of vinegar and salt water, my battery charger and q-tips. Similar to this video. It takes about 20 minutes to get a deep enough etch.MG_Willy wrote:How did you etch it? I understand the vinyl but what process and how long did it take?

Cool thank you...

I'm using straight salt water, haven't tried vinegar. Does it give a better result?atc250r18 wrote:I use a 50/50 blend of vinegar and salt water, my battery charger and q-tips. Similar to this video.

Not that it's perfect, but I'm using a spare car battery for my power source, and get a pretty deep etch in less than a minute. It will tend to pinhole through a laser toner mask though, hence the desire to obtain vinyl masks.

I didn't have much luck with straight saltwater on stainless, aluminum was okay. I run my amperage at the 100 amp setting, which is quite a bit less then a 750CCA battery. The couple that make my stencils are encouraged but hesitant to start making too much stuff. He's a submariner and She's got plenty of kiddo's to deal with. I'll keep on him, I gave them a hundred bucks for double stencils for 8 form 1's and Fire/Safe stencils for three 80% lower's. I figured that was way cheaper than getting each form 1 engraved at 75 bucks a pop.
Here's a couple more, the top one is 316 stainless the bottom one is 6061.
Re: 308 316 Stainless Clipped Cone Sealed build
I have done testing on 316 ss using an ATV battery, worked well enough that when I finish my form 1 that's the process I will use.
I use felt stretched over copper and salt water(water that will not dissolve any more salt).
It takes less then 30 seconds.

Re: 308 316 Stainless Clipped Cone Sealed build
I started using this white padding (like felt), wrapped over a motor brush.
I get much more consistent results.
I use a 24Vdc power supply and haven't tried going over 2A.
Tap water with some Sea Salt. Yet to try vinegar.

have you tried swabbing ferric or muriatic acid?
