Parachute Hardware Tech Spec and Drawings? Rig Patterns?

[rifleman 70]

This is going to sound a little weird but here goes. I'm trying to find technical specifications and engineering drawings for all the standard parachute hardware; chest strap adjuster, 3 ring release etc. as I'm trying to make a 1/3 scale rig for a one-off, 2' tall collectors edition teddy bear. I have somewhere local that will do small run casting but I need to get hold of drawings to scale down.

In addition, I'd like to be able to make the rig itself a scale copy of a real world H/C system but don't know if that's possible.

Any advice, information or possible leads would be gratefully accepted.

This is an ongoing project that I'm working on when time allows and once completed I'm hoping to raffle/auction/donate it for charity.

That's going to make for an awfully expensive teddy bear.

I'd just go to a good outdoor sports store like REI, Bass Pro or Gander, and look at the backpack repair components they have. There are all sorts of little buckles and stuff made out of sturdy plastic that would be a good simulation for parachute hardware, at a very small cost compared to doing a special run of steel castings in one-third scale.

Stuf like this:

Excerpt from rigging manual

Scroll down to pg 3-13

Other more detailed specifications can be found in the PIA and Marine hardware catalogs, like CWH, wichard, and a zillion others as well as the DOD and paragear and ...
C

Other examples, clicky but your going to have to go to the Dod specifications to get the exact numbers

But what do I know, "I only have one tandem jump."

That's the whole point of the exercise. I've taken the time to source a good pattern for the bear that I've used to make 2' tall bears before, I've found a stockist of high quality wood wool (rather than the usual polyester stuffing) and I've found a manufacturer of heritage quality eyes, nose and joints.

I'm currently looking at samples of high-quality pure mohair fur in various lengths and colours so that I can choose the one that brings out the character in the bear.

Once the bear is assembled and stuffed, I'll make a pattern for a RW jumpsuit direct from the bear.

As far as the rig is concerned, what I'm aiming for is a perfect 1/3 scale model of a real rig complete with risers, main, reserve, d-bags and pilot chutes.

All of the "mil-spec" hardware hasn't been mil-spec since 1998. They were cancelled by the military and taken over by the Parachute Industry Association. Spec are for sale at http://www.pia.com/shophardwarestds.htm. You won't find all of the hardware because some are outside of this system. But you not going to get 1/3rd scale housings, cable, webbing?

Most of the webbing on rigs appears to be approx 2.25" so I can use 0.75" and then just machine the appropriate check stitching into the appropriate location. Cable can be replaced with braided picture hanging wire. Not sure about housings but I could possibly use flexible plastic tube sprayed silver.

Webbing is 1 23/32".

See that's what I said. I'm sleep deprived after having two seven year olds and a 5 year old get up 4.

I knew 22/32 didn't look right. Time for a nap.

Based on that fact 1/3 scale is just a tad shy of 18/32" so the nearest commercially available webbing size to that is 1/2".
