i'm in cyprus and we're kind of isolated here
Doh! I didn't even see that... just assumed you were in the U.S. ... very risky assumption (see my location)... sorry about that.
utnapistim:
This is why i put the picture of the unbroken one (I was hoping you'd be able to tell me which type it is
). I don't know how to tell the difference. (i've also looked online - on the address you posted - and couldn't tell the difference between single and dual release.
so, what is the difference between the two types?
(sorry for asking such questions

)
No problem at all with the questions... I'm glad to be able to answer some, for once!
A dual-adjust buckle is one that you can adjust from both sides once it's buckled; the straps on both sides should have D-rings so you can pull them toward the sides, and the buckle stays in the center. A single-adjust buckle is fixed on one side; it's stitched onto the strap there... and you can adjust it only from the other side... and the buckle isn't necessarily centered.
Hoosier says it's a dual-adjust buckle on the Orion, and he ought to know.
OK... if you can't send it back, then Hoosier is right... the simplest way of fixing this would be to cut off the D-ring, and just sew the broken side of the buckle to the strap on that side. In effect, you'd then have a single-adjust buckle. Assuming the remaining bar there would be strong enough...
Getting a new double-adjust buckle, though, would be the best solution... if you can find a buckle. It doesn't have to be identical, though a lot of this kind of stuff does seem to be identical... If the buckle is designed for 2-inch (5-cm) webbing, it will work -- you'd be getting the whole buckle, male and female sides.
I can't tell whether strapworks.com ships overseas... you may have to e-mail them and ask. The postage, of course, would be far more than the $1.75 cost of the buckle, but you're used to that, eh?
But in either case, you're going to have to get the strapping stitched. I would guess you could find a place (shoe repair?) that could do this for you... you just have to make sure they use heavy-duty
nylon thread, not polyester... no-one is sure how well polyester would hold up underwater.
Otherwise, to do it yourself, you need a sewing awl. There seem to be two types most-available in the U.S. ... you
don't want
this type, called a Stewart Speedy Stitcher; not because there's anything wrong with the awl, but because it uses polyester thread.
What you want is
this type, with nylon thread. You can tell the difference by the fact that this type has an integrated spool of black waxed thread between the wood handle and the needle -- that's what I have, and I'm pretty certain the thread is nylon. And I see that this merchant does ship overseas.
I haven't been able to find one place that offers both the buckles and the awls, and that ships overseas.
Let us know what happens!
