csmw 98 Posted June 15, 2011 Report Share Posted June 15, 2011 Shitty camera and lighting and blurry, but you can see profiles. Camera is making polish looked 'jacked', but it is not....it is smooth/shiny/high-polished. Galil Carrier Left bolt Middle bolt Perfect circumference Profile Run-out before hand blending/polishing: 0.000" Run-out after hand-blending/polishing: 0.002" Zero'd, run-out.... left side: 0.000 Run-out.... center: 0.002" Run-out.... right side: 0.000" All profiling, machine cut. 2 Quote Link to post Share on other sites
Guns Are Great 140 Posted June 15, 2011 Report Share Posted June 15, 2011 I think they look good! The Galil handle lloks good also! Quote Link to post Share on other sites
csmw 98 Posted June 15, 2011 Author Report Share Posted June 15, 2011 I think they look good! The Galil handle lloks good also! Thanks man! I am really unhappy with the way the pictures turned out....lots of distortions and really makes the high-polish look dull. Posted them anyway, at least you can see profiles, and they are high-polish, so no issues other than w/ the pics. Thanks again! Quote Link to post Share on other sites

poolingmyignorance 2,191 Posted June 16, 2011 Report Share Posted June 16, 2011 Thats some pretty extreme profiling. Is that just to aid in loading on a closed bolt? Quote Link to post Share on other sites
csmw 98 Posted June 16, 2011 Author Report Share Posted June 16, 2011 Is that just to aid in loading on a closed bolt? No. You can load on closed bolt, but that was completely unimportant/irrelevant when we designed our profiling. Quote Link to post Share on other sites

snafu360 21 Posted June 29, 2011 Report Share Posted June 29, 2011 (edited) Is that just to aid in loading on a closed bolt? No. You can load on closed bolt, but that was completely unimportant/irrelevant when we designed our profiling. Excuse my ignorance,but what is the point of your profiling? The work looks very good,I'm a machinist and love to see stuff D.N.O Just trying to figure out the benefit other than being able to load on a closed bolt easier. And I don't know about you, lol but being able to load a closed bolt is important to me. Thanks Edited June 29, 2011 by snafu360 Quote Link to post Share on other sites
Paulyski 2,227 Posted June 29, 2011 Report Share Posted June 29, 2011 Just trying to figure out the benefit other than being able to load on a closed bolt easier. Reducing resistance from the shell in the top of the mag that's pressed against the bolt as the bolt rotates against it, then travels rearward in the weapon's ejection cycle. That's why the profiles are rounded rather than ground flat. Grinding them flat in 1 area would aid in mag insertion, but the proper profile in all areas of the shell's contact with the bolt & properly profiling the hammer & underside of the carrier really reduces resistance & keeps power in the cycle that would otherwise be eaten up by uneven / unnecessary transitions. Good Job Matt. Quote Link to post Share on other sites
