I'm almost ready to finish my tube form my latest can and I have a question for the masses.
As of right now I can fit 7 K's in with a .375 long ss spacer as the blast chamber.
Should I eliminate the spacer, shorten the K's and squeeze in another K?
It's a .45 can.
Thanks, R.
Extra K or small blast chamber?

Whats the length of the can?
We need more than 1 measurement to be able to give any insight.
Re: Extra K or small blast chamber?
Id of the can is 1.345.
Can lenght is 9 inches.
Booster lenght from "front" to the shoulder that meets the tube is 1.634. Overall booster lenght is 2.072 incuding piston.
Eack K is .945 long.
Tube lenght to have a overall of 9 inches once the booster and end cap are installed will be 8.250 +- some. I havent taken more accurate measurements on that yet.
So the differnce between a k and the spacer is .570 If I divide that by 8 baffles. I would need to skim off .071 from the skirt/cone of each baffle to get
8 to fit where 7 do now with a .375 spacer.
So which would perform better?

Re: Extra K or small blast chamber?
Personally I would think you would need the expansion, and with 7 baffles already.....but, I have zero experience with that baffle design and do not have the knowledge about what they need and don't need.

Re: Extra K or small blast chamber?
Is your piston ported or unported?
Re: Extra K or small blast chamber?
Piston and the booster assembly are both ported.
Re: Extra K or small blast chamber?
I would really love to see pics of your progress. A .45 can is in my thoughts for a future form 1.

Re: Extra K or small blast chamber?
You're gong to need an expansion chamber (size??).
The .45 is a big hole and I don't think sticking the extra K in there is going to help
the way you think unless you were building an integral carbine setup with more length.
I think gong the other way ....
Bigger expansion chamber and six K's with proper skirts/cones might be better.

Re: Extra K or small blast chamber?
@Twodollarbill Thanks, with the 3/8 spacer and the extra volume in and around the booster I think it should be a acceptable blast chamber with 7 baffles, plus the work I have put into the baffles so far might go to scrap if I take to much off so I'm playing it safe.
@DaveSB After Its complete I plan on doing a youtube video with detailed explainations for all 3 of my form 1's that I have built with the advice and help from numerous members of this forum.

Re: Extra K or small blast chamber?
Size the blast chamber properly to suit the best sound/ back pressure. If you are trying to meet the length without shortening the suppressor, add the extra length on the opposite end with a spacer or odd length baffle.
