In step 5 I used a parting tool to plunge cut to the final depth. Then in step 6 I take off the shoulder and then keep taking off more and more with the compound set at the right angle.Noxspector wrote:Excellent post!!!!!!
How do you maintain the angle in step#6? Do you set the tool head to the angle you want and start with the deepest cut then move the tool out (Diameter) and up (forward on the baffle) then make another cut not so deep that it matches up with the previous cut?
think i would need that for a .22 can??WhisperFan wrote:Some of the gas the gets trapped by the front of disc of the K-baffle (the dished portion). The 'mouse-hole' allows a portion of that gas to get back into the "K" portion of the baffle before it.canenvy wrote:why the hole in step 10??
Hope that's not too hard to understand.

I was thinking of milling the holes. I wouldnt touch a baffle with a drill bit.soundless wrote:Of course it would. U will notice a nice difference after you drill the mouse holes.hotbrass wrote:I have a can with k baffles but no mouse holes.
Do you think it would benefit from mouse holes?
How much of a difference will I notice?

I don't .... That is what the mousehole at the bottom of the cone is for.Closed Casket wrote:Do you mill any holes on the rear of the k baffles that would leak gas into the cone?

Re: .
This doesn't mean to sound smart-assed .... but the countersink goes in all the way. Even if the countersink goes in all the way until the edge becomes sharp, you can always face off the sharp edge.Wyatt9k wrote:In step 3 how far do you know to go in with the countersink?
Once you set the compound rest you taper the outside the same as the inside.Wyatt9k wrote:And then in step 6 how do you taper the outside down to where they are both parallel?

I'm just starting to research this stuff to build on a Form 1. (By 'this stuff' I mean can designs.)bakerjw wrote:I'll try an explanation without pictures.
As gases accumulate in the chamber just before the flat part of the K, the hole in question directs them into the outer chamber of the K. The gases pass around the outside of the K until they come to the slotted hole on the left side of the picture. They then pass into the open cone area of the K where they are directed into the hole in question in the next baffle thus directing more gas into the outer chamber of that K baffle. for best operation the baffles need to have these holes aligned.
Question:
Doesn't the assymetry of this hole (step 11) cause the bullet's path to deflect? What I mean by this is if the crown on the muzzle of a barrel is dorked up (assymetrical), the gases following and surrounding the bullet upon exit also become assymetrical and throw off the bullet's path slightly. This affects accuracy in a negative way.
These ports seem like they would have a similar effect unless they were alternated in the stack to 'balance' out the effect...? Or instead of one large port off-center, why not put 2 or 3 smaller ones to keep the symmetry intact?
I'm not saying it doesn't work for sound reduction but I would worry about baffle strikes and random accuracy.
Anybody have info to agree or disagree with this?
Thanks

These baffles have been around for years - I didnt' make them up. I believe that the whole system works because the bullet has already passed by the baffle and the baffle is taking care of the gas behind it.mylerw wrote:I'm not saying it doesn't work for sound reduction but I would worry about baffle strikes and random accuracy.

because if you understood how the baffle actually functioned you would realize that would defeat the purpose of the portmylerw wrote: Or instead of one large port off-center, why not put 2 or 3 smaller ones to keep the symmetry intact?
You would be wrong, allmost EVERY modern baffle design is asymetric to some degree (even SRT's baffles have a scoop)mylerw wrote:I'm not saying it doesn't work for sound reduction but I would worry about baffle strikes and random accuracy.

K Baffles
Hello, thanks for the info, can I ask please what size is the mill cutter that you use for the mouse holes and for the slot at the top of the K baffle, is this important in regard to the size of the bore, are they both the same size or is one smaller that the other THANKS

Re: K Baffles
.3125" for both I use a size slightly smaller than the bore size.kiwi collector wrote:Hello, thanks for the info, can I ask please what size is the mill cutter that you use for the mouse holes and for the slot at the top of the K baffle, is this important in regard to the size of the bore, are they both the same size or is one smaller that the other THANKS
