Materials science / Laser cutting Tegris
« on: March 19, 2020, 03:47:04 AM »

How do you guys achieve a smooth finish on the underside when laser cutting Tegris sheets?
We found that raising the sheet above the table on spikes/magnets helped a bit but the edges are molten and agressive.
I can see that other companies manage to have a clean underside.
Do we need mechanical cleaning/deburring? Seems like a very time-consuming solution.

Materials science / Looking for IRR black tubular webbing type 5625 1 inch
« on: September 15, 2018, 02:14:47 AM »

Everything's in the title... We currently use commercial black type 5625 that shines quite a bit in NVGs.
Anyone knows a supplier for IRR treated black?


I received a message from my contact at FirstSpear about the 2M ROC buckles we use along with some other brands in Europe and the USA.
FirstSpear believes the buckles infringe on their Tubes pattern and are starting the legal action.

For context: NFM has the distribution rights for Tubes in Europe but FirstSpear acknowledges that NFM is not selling them to anyone.
FirstSpear will not OEM produce carriers for export to Europe because of the NFM agreement so this way is blocked as well.
I heard that the Lindnerhof proprietary buckles might be available for sale.
I would rather use buckles from a manufacturer instead of a competitor for obvious reasons.

I haven't read the Tubes patent and can't judge whether the infringement claim stands (not a lawyer).
Link to the patent:
I have written about this to 2M and will keep you posted.

Concept, design, and engineering / Cummerbund back attachment solutions
« on: January 23, 2018, 01:36:33 AM »

I'd like to pick your brains about the different systems out there used for attaching and adjusting cummerbunds on vests.
I'm facing a decision to choose a system for a range of laminate lasercut cummerbunds that may or may not adjust in the front (velcro or ROC buckle closure).
The cummerbund will attach under a PALS layer (opening via flap) on the back. No QD system is required.

Here are the choices I see:
- laced cord (think Eagle Industries PC) with cord locking hardware;
- laced thick elastic cord (think Crye JPC) with a knot;
- laced thin elastic cord with cord locking hardware (Eagle MMC);
- elastic webbing and velcro (any covert carry plate carrier on the market);
- vertical bars locking in PALS slots (IOTV Gen3);

What do you think is optimal? Or are there other good solutions that I didn't consider?

Hello all,

I've been cutting with a 1600x1000mm 130W laser for a month now (Bodor 1610 if you ask).
The supplied ventilator was weak so I found myself a 1,1kW/230W ventilator with 1100Pa of pressure. Better but still no suction on, say a 1500x1000 1,5mm PEHD sheet that's slightly warped.
How do you guys choose ventilators? Is there a formula for calculating the correct depression?
Also, do you use secondary ventilators to extract the air from over the table (I have an exhaust tube under the table and another one over it)?

Workspace, tools, machinery, and manufacturing / Rifle magazine props
« on: September 27, 2017, 12:30:21 AM »
Hi all,

I would like to pick your brains about the most efficient way to acquire fake rifle magazines for design and photo purposes. Ideally 6-8/type.

As you may know here in France assault weapon magazines are restricted unless one carries a licence for said weapon. No way to do that for many types of magazine.
I've seen molded mags for kydex holster designers but at 45USD/piece the bill is stiff.
Airsoft mags are fine for pictures but not long enough actually.

I've been thinking about 3D printing them (need to acquire/draw CAD files, long work time, cost unknown), molding them (I can borrow some samples from a weapon distributor but no molding capability in-house), even laser cutting them from layers of MDF (not sexy).

Did anyone solve this problem and how?

Hello gents,

Currently I force the foam piece into a plastic tube, insert the tube into the shoulder strap, pinch and retract the tube while massaging the foam to fill the strap.
I'm aware that the industry uses metal tubes cut lengthwise where the insertion of the foam is much quicker. However, that means manufacturing a special tool for each needed width (not even sure if that requires cutting a metal tube or rolling a metal sheet).
Someone suggested that I try to pull the foam wrapped in a plastic bag through the strap then remove the bag.
Another suggestion was to use the kind of square plastic tube used to run electrical cables in buildings (top is removable so foam insertion is fast).

What method are you using?

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

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.

Hi guys, I'm Bootcat, based in France, owner of the Tiger Tailor company ( You may know me from the DIY Forum.

Been sewing gear for about 11 years, fulltime since 2010.

I'm mostly doing design work for government tenders and special users' groups (MIL and LE) in France and Belgium, and OEM work for a couple of bigger brands, with overseas production.
When I have some time left, I work on the Tiger Tailor range and try to keep up with late orders.
I could use a factory for small batch orders, feel free to share if you know somebody who accepts work!
