Concept, design, and engineering / Good dimensions for 2xAK pouches
« on: December 29, 2015, 10:02:43 AM »
Hello,

I have a new project that requires double AK pouches with short flaps, because there will be PALS on the pouch face. They will look similar to the pouches on the Tasmanian Tiger chest rigs.
I know I should use a full height separator to stabilize the back magazine when the front one is removed.
I also know the fabric should be doubled for wear resistance
.
This said, I have no access to real AK-47 mags, only airsoft ones which are shorter (I believe real ones are 9,25" high).
Experimentally, I calculated a possible pouch size to be 3,5" wide x 2,5" thick x 6,5" high, i.e. 8,9cm x 6,3cm x 16,5cm. A lower pouch might be less wide but here the extra height is useful because of the PALS.

I'd like to know what your experience is with usable/correct dimensions for these pouches.

I use 400D packloth for police and army vests. It works well but there is still some abrasion occuring around the collar when the neck opening is narrow.

Can't say much because I have very similar designs in my catalog  ;).
Some finger purchase space on the flap is useful. Try to open it with cold wet gloves to confirm.
Reinforcing lower corners with webbing - I reverse engineered that from pictures, it's a PITA to sew inside-out and then on the outside again. Just adding tolerance in the pouch dimensions is enough for wear prevention in my experience.
The shock cord tunnel seems to be a bit tight for smooth operation.
External seams are a good thing because you may want to sew the same pouches on a carrier panel or a multi-pouch configuration at a later time. Inside seams wouldn't work for that.

I'm working on the same topic. I would add that pine tree pins are a pain to extract from the mesh if you go to ground in the forest.
For me, a 4-way stretch nylon/something fabric will go where the cushions are. The flat areas can be done with Cordura or packcloth.

Now, to find an affordable and resistant and elastic and good-colored stretch fabric, that is a problem awaiting a good solution...

Good work here.

A few suggestions for you:
You may want to have semi-felled seams on the outside of legs, they are sturdier. You probably know that the inside leg seam is closed as last on pants (but before the cuffs of course).
You could cut the legs just below the knee and do the thigh piece as a tube with a rear seam for example, it may give you options for the ventilation channels.
I don't see darts on the knees, they awesome for high mobility pants, try them sometime. Doing the thigh tube at an angle could save you the lower darts.
For air flow, you want to have inflow at the cuff and outflow around the thigh. Making mesh bug-stopping inner gaiters (like Danish military pants gaiters) would allow your pants to be open at the outside cuff for inflow.
In my experience two air vents closed with zippers with mesh underneath, running vertically, one near the inner thigh seam, the other near the outer thigh seam, allow for noticeable airflow during walking. The thigh movement will pump the air out through these vents.
Closure may be useful because the night can be colder in the jungle.
Ventilation on the butt seems unnecessary as this area is tensioned all the time or under a belt or pack.

Wouldn't a simple SAW100 pouch do the job? (I haven't checked the dimensions).

Your price point is at the "generic made in China" level (think Flyye/Pantac). 200 would be more like it.
You should add a line drawing with the dimensions.
Also, your pictures don't show the inside of the bag - are there pouches? separators? velcro area?
Take a look at Kickstarter pages for backpacks, there's usually good marketing at work there.

Myself, I use an automatic triple stitch with roughly center start/center stop. My bartacker is not a 42-point machine so I use it for other applications than PALS.

The bartack is preferable because the zigzag spreads the tear stress on a larger area than a straight stitch (it means more Cordura fibers are captured by the thread). Also, with a multiple straight stitch, the needle cuts or at least splits the thread already sewn when going back and forth. This means the Cordura under the stitch is more likely to rip as holes are closer together. In my experience straight is strong enough but the bartack will be stronger. Oftentimes I design a double layer of Cordura or a webbing piece under the most loaded PALS locations.

Materials science / Re: Source for milspec ranger green #69 thread?
« on: November 03, 2015, 08:33:43 AM »
FWIW, the correct A&E Ranger matched color is called Army Neutral Mode. ODS-1 is much too dark, almost black, that is not a good match. A&E OD is a fair match indeed.

Not the French pattern for the webbing, the shapes are too blocky. Not Polish either.  Might it be Netherlands DPM?

On my crappy mechanical non-adjustable bartacker (Brother series) I try to use Linhanyl bonded thread because of this issue.
I also started putting Froglube lubricant (liquid) in the small container where the thread is lubricated and coating the needle (with FL paste) before sewing, since Froglube has an excellent friction reducing effect (and I sell the product, so it was obvious to try it). Very good reduction of heat build-up with a standard nylon thread, less fraying, and the consumption is minimal. I sew a lot of tubular webbing with 4mm shock cord inside that gives a lot of friction (because of the rubber in the cord).

Didn't have that minimum applied to my order or mentioned.

FWIW, Camelbak used to offer magazine pouches with a V-notch cut where you place your drain. The sides of the notch are folded once on the verso side for a clean finish.
Nice solution with stopping the stitching, I'll give it a try.

The Jungle Ruck is the Tyr Tactical product on a composite ALICE-like frame.

These are excessive capacities for assault or patrol IMHO. 49 to 65L for the Assault pack is bigger than the Alice Large pack for instance.

That's useful. The US Army will also need the 1606MC for the future Molle 4000 ruck that is being tested.
