That is really cool. I'm gonna have to make one... I have a quick question. (I don't really want to look through all 37 pages) do you buy your bands on the Internet? (i live in america)

He uses therabands found on ebay for work-out purposes. There are different types of tubular and sheet rubber, have a look around google for a table for the different strengths(its colour coded).

As you know, I like Thera Band.
Especially the thinner variants (blue or black) have lots of power, very fast rubber. BUT you always have to layer it, fold it, whatever.
I wanted to make a slingshot that can take a full width (138 mm) Thera Band without any folding or layering. This of course means that it has to be freakin wide! A monster slingshot.
Of course I like low forks, so the angle between the fork arms had to be very very low.
And the clamp-on method is the only one that works. I made the clamp from a 10mm steel rod, and put Thera Tube yellow over it to increase the friction. This holds 100%, and band change is really easy.
The slingshot really shoots well. Best feature is that the bands never tangle, reloading is very very quick.

After a whole day of filing, sanding and polishing, the frame of my first desert ironwood slingshot is done.
There are indeed fine cracks, but they are in an uncritical part, plus I have stablized the frame with 8 mm steel rods. Those rods can hold the force even without the wood. This glovehsot has a heart of stainless steel!
I used another part of my croc belt for the hand brace.
The shine of the wood is just phenomenal. No epoxy, no stainer, no wax, just natural. Fantastic!
It is a tough material, and the dust is not pleasant. But the work is worth it!

What type of wood is it?

Hello,
I have rummaged through my slingshot leftover pile and found a few pieces of Arizona desert ironwood. Not enough to cut a complete slingshot, but too beautiful to let go to waste.
So I turned a steel skeleton from a massive one inch stainless steel rod and attached the round leftover wood to it.
It actually came out nice. A light shooter, this time with a higher fork and plain, modest over the top band attachment.
I like this slingshot. It is very solid, 8 mm steel up to the tips of the wood.

The first Jörg Sprave Dankung slingshot now available!
Posted: Wed Apr 21, 2010 5:29 am
Hello,
this is to let you know that the video introduction of the first Jörg Sprave Dankung will come out this coming weekend.
The Chinese already put the product up on their website, here:
http://www.dankung.com/emart/index.php? ... cts_id=322
The Chinese made a stainless steel casting mould for the design! It took a long time to optimize everything, but it came out very nice.
Every slingshot is engraved with my signature and marked "Special Edition" or even "Limited edition" (the latter won't be available from Dankung, but sold by selected European and US dealers only).
The design allows "Over The Top" flat band attachment (works for all kinds of flat bands, including Hunterbands, Bill Herriman's and Flatband's fine products). But it also allows the classical "pretzel" tubular band attachment.
The product is polished to a high sheen, not chrome plated like some of the less elaborate models.
The product will be available right after the introduction.
To make that point clear, I am not financially involved in this. I gave the design to Dankung for free, and I sure hope they will sell a ton of slingshots. These guys are eager, reliable and committed.
Watch out for the video!

Very, very cool indeed! Must be nice to have one of your designs turned into an actual product.
