gliney00 Posted September 25, 2014 Share Posted September 25, 2014 (edited) I think I am going to cut one and see how it functions Edited September 25, 2014 by gliney00 Link to comment Share on other sites More sharing options...
Pat Miles Posted September 25, 2014 Share Posted September 25, 2014 Only one way to find out...cut away! Link to comment Share on other sites More sharing options...
tacticalCOWBOY Posted September 25, 2014 Share Posted September 25, 2014 I dont know how comps work but I would think that this one would push the gun down a lot. But what do I know. Cut one out and let us know Link to comment Share on other sites More sharing options...
polymerfeelsweirdman Posted September 25, 2014 Share Posted September 25, 2014 Yeah that looks like it's going to nose dive the muzzle Link to comment Share on other sites More sharing options...
Mark Gale Posted September 25, 2014 Share Posted September 25, 2014 Your design is very similar to a number of comps in a wide and deep market. If this is just a one off project to make chips and burn time, cut away. If it's a commercial beginning, it's going to be expensive and it's gonna hurt...

It would be for my own amusement, The only reason it exists this far is I am getting rusty modeling in Solidworks and needed a few projects, the only reason a couple might exist in real life is I have machines in my garage and I am curios Link to comment Share on other sites More sharing options...

TonytheTiger Posted September 26, 2014 Share Posted September 26, 2014 Not bad looking but I'd be surprised if your third hole and fourth baffle where doing anything. There's a finite amount of gas exiting your muzzle and the little that 223 puts out would probably be all spent by the time it gets that far. Assuming your pictured design is gonna be around the 1x3 size I think it could be made just as effective in 3/4s of that length. A bigger caliber could probably take advantage of all that baffle surface area but it's most likely overkill for the little guys. Just my .02, I could be wrong, it happened once before.

gliney00 Posted September 26, 2014 Author Share Posted September 26, 2014 The other configuration in my model is shorter, has three sets of ports and two holes. I wanted to play with the real estate allowed in tac optics and go from there. Link to comment Share on other sites More sharing options...
v1911 Posted September 26, 2014 Share Posted September 26, 2014 Maybe start with 2 holes and then move on to 3? Maybe even play with the configuration of the holes to see what works. Link to comment Share on other sites More sharing options...
polymerfeelsweirdman Posted September 26, 2014 Share Posted September 26, 2014 How about try closing the 2nd from the front chamber and/or the 3rd from the front chamber to increase pressure in the final chamber assuming I haven't forgotten my physics Link to comment Share on other sites More sharing options...
gliney00 Posted September 27, 2014 Author Share Posted September 27, 2014 played around a little more today, rotated the wrench flats and extended them the length of the comp, cut down the length and the amount of porting. Link to comment Share on other sites More sharing options...
Nickoli Posted October 4, 2014 Share Posted October 4, 2014 Looks interesting and similar to a comp I am running now made by another member on here. I would think with the side ports being closed at the bottom and the holes on the top it will give you a lot of downforce. The one I have has the side ports but does not have any holes and it works very well for my gun. Link to comment Share on other sites More sharing options...
co-exprs Posted October 4, 2014 Share Posted October 4, 2014 Yeah, I would start with only small pilot holes on top and then open them up as you find that you need to. As you get better at managing recoil, you need less and less down force. My 308 brake had very small top jets because the large holes I put in the first prototype drove the muzzle into the ground. You can always punch the holes bigger, but you can't easily closr them back up. Link to comment Share on other sites More sharing options...
Stlhead Posted October 4, 2014 Share Posted October 4, 2014 It looks like a fine place to start, enjoy your tinker time! Link to comment Share on other sites More sharing options...
v1911 Posted October 4, 2014 Share Posted October 4, 2014 Unless you tap the holes to place jets to be able to adjust the airflow. Then depending on the ammo used, you'd be able to tune your comp as well as the gas block. Link to comment Share on other sites More sharing options...
Meat Target Posted October 7, 2014 Share Posted October 7, 2014 From running a bunch of different CFD analysis on different comp here would be my 2 cents on your design. 1) Your going to have way too much down force, reduce the area of the flats on the bottom of the ports. 2) Ditch the holes in the top, not need. 3) Increase the opening area in the sides of the ports. 4) Make the second port spacing larger (as the pressure drops the gas expands less) 5) As long as you port openings are fairly large there is no need to have more two sets of ports.

gliney00 Posted December 3, 2014 Author Share Posted December 3, 2014 I 3D printed the second design for laughs, but I haven't had time to cut one yet Link to comment Share on other sites More sharing options...
Bear1142 Posted December 3, 2014 Share Posted December 3, 2014 Yeah, way too much downforce. You might need one top port at half of the diameter you currently have. Link to comment Share on other sites More sharing options...
1eyedfatman Posted December 3, 2014 Share Posted December 3, 2014 I like 3 side holes with 2-3 top holes going from large to small on top. Link to comment Share on other sites More sharing options...
