DMM throw hook.

On a German supplier's website today. Looks like the solo hook is finally available.
 
Hi Moss. I know I could be wrong - but as far as I'm aware I cannot see the climber tied in twice all the time when ascending on the hook.

He always has his lanyard around the tree while he's ascending on the hook. When he resets the lanyard to get around a limb he's doing a static hang on the hook which is probably the safest way you could be on it, assuming the hook is rated well enough to hold his static weight securely. It's not going to jump off the limb in a static hang. His lanyard looks a bit toasted though ;-) I wouldn't advance that way myself, it's much easier and less gear to simply put a throw bag on the end of a rope or lanyard. I don't think he's endangering his life.

I was looking around the shop one day for a rod to bend into a throw hook when I found these u bolts from two different sized trailer axles. They work very well and cheap. Cut one side of the threads off and welded on cat 1 to cat 2 tractor 3pt linkage bushing and ground the threads smooth on the other side.

Nice work, poda! Thanks for posting the idea and the photographs!

If you had to guess how much one of those trailer axle U-bolts cost new, what would you say?

Great idea, and a nice way to save a considerable amount of cash, if you've got the welding skills and equipment already, or a friend who does.

Hey Poda, do you use the D carabiner on the welded tube end, and if so doesn't it put force on one side more than the other?
Thanks, Dave

Hey, Dave! I'd be guessing that poda only included the biner in the photo in order to provide scale as to the size of his hooks, using an item that is common and readily recognizable to most climbers. I could be wrong, though. Hopefully poda chimes back in on this. Thanks.

Good Afternoon Tim, I sort of figured that he used it for a scale/ratio, but I have seen some crazy shat out there! I could see a Delta link working very nicely, so your rope can be used for other purposes, but I don't see an eye splice lasting very long with the edges of the tubing as a connection point. IMO. Why not just weld a steel ring on the end of the hook? That would be more conducive to a ropes life.
 
Yaul are correct biner was for scale . Steel ring does sound like good idea . Made this about a year ago and followed the epple design. Not positive on cost of u bolt it was scrap. Eye splice would not work it's a little rough. I use a shackle with an eye splice.

I agree - probably only good for short ascents (and experimentation). In reality, if I'm honest - I'd try what this climber has done (all apart from the japanese tree spikes, and the swinging at the end - I don't like the idea of tempting fate too much). As far as I'm aware - I'd be breaking the manufacturer's rules in doing so; I can see this conversation coming up again and again for this product as people begin to realise it's potential - though it is for these conflicting reasons that I find it interesting and exciting.

I suppose if the climber still 2 and 1'd that lanyard it would be safer (or had a slack choke following them, assuming larger ascents were done in this fashion).

An idea popped into my head and I can't shake it. I'm going to try it Monday.

You know how there is often a small branch or one of multiple tops that you could just cut and let drop if only it was a foot more to the right of the object below it? Or if only its weight favored the right a little more?

Monday I'm going to place the Hook in the frilly ends of a few different light tops in a multiple leader tree and give them a little pressure to one side and away from an object I will miss.

As the 20 lb tops fall the lacey ends should just slide out of the hook and I can repeat.
