Is their any trick to orienting the baffles in the can or slide them in and go?

I try to orientate them the same... but could not really hear a dereference when miss matched.

I tried mine all lined up the same, every other one opposite, & just random. They all sounded the same. There might be some slight difference but from behind the gun I can't tell if there is.

That makes me happy, I've been pondering this same question, and am currently making my first K baffle silencer.

Here is a pic of K baffles after about 20 rounds of 22lr that were placed opposite to the previous one.
Notice that the blast follows the mouse hole of the K before it. (left to right)
Would you think this placement gives an easier path forward for the gases.
Is this good or bad
I think it lets the next scoop do what it was designed to do.

line them up the same. works in the big boy produced pistol cans.

Another interesting observation...looks like 6 baffles do all the work. Past that, doesn't look like they're doing much other than taking up space.

Anyone have any ideas if that, as a generalization, is true? $2, what is the OD of the Ks you use, and how long are they?

I'm trying to figure out how short you can go and still get good suppression, and trying to see the relationship between diameter and length for Ks.

Interesting observation, Byrdman, a name reminding me of a Jazz great. This
caused me to think about how Jazz Men mute their trumpets.

e.g., << http://www.wwbw.com/Woodwind---Brasswin ... 932t0.wwbw >>

What if one were to reduce the number of K's and use a 'trumpet-mute' type of spacer after each K?

I sketched some possibilities and at first view the configuration would introduce a 'longer surface'
for the blast to follow/delay which in turn would stretch out exit gases:

=> [[ [ 1st blast chamber ] / K / <) / K / <) / K / <) ]] =>

Time to take a break -- "Take Five" -- and get back to solving.

Those K Baffles in the pic were .865" dia , .600" long.

Remember....the buildup was only after 20 rounds.
After about 200 rounds the entire length of the suppressor shows deposits.

That pic really shows that as the blast enters the next cone of the K Baffle "hooks, curves, migrates,
leans" towards the mouse hole as the deposits on the back of the next K baffle clearly show.
So scoops and mouse holes working together...do work in directing gases.

I have found with 22lr K Baffles....a smaller diameter tube works best.

Please accept my compliments on your execution and machining.
I was remiss when you first showed.

Your series of shots makes one feel that they were there with you enjoying the
process and marveling at the final result.

Best.

I too have played with those ideas....realizing in the end that you still need "that length" if you
are not using some type of bore closing wipe at the end.

The least number I have done is SIX K Baffles with a 1" OD tube, it was good, but SEVEN sounded better.

My current project is with NINE K Baffles in a Ruger 10/22. Only because I had the length to do it.
All I can say is that I picked the wrong weapon. 10/22's are nice, but the action makes too much noise.

I wish I had built it on a Bolt Action.

Thanks Historian for the the "Take Five" link.....it's been awhile.

A kindred spirit and with good taste.

I shall not presume that you have seen my continually tedious
references to the Gold Standard of .22 suppressors. Empirical
evidence is the best.

What kind of bolt buffer pin are you using? That makes a HUGE difference with 10/22 action noise.

If you're still using the stock steel pin, PM me your address. I'll send you a buffer that works like a champ.

Byrdman

I do have a pack of buffers coming, but thank you.

Along with some items from Volquartsen

I could use some help quieting mine down.... Does just the pin make a lot of difference or are there other metal-to-metal issues that need addressed as well?

I'd say that 90% of the 'action noise' of a 10/22 is the bolt hitting the pin; the rest is blowback from the suppressor keeping pressure up a little in the barrel and blowing out when the bolt cracks open.

Remind me, and I'll get you a buffer next time we're together.

Byrdman

Cool. Heading to range Sunday if you want to go.
