    I've got to show this off just a bit...

    Some of you know that in my 'other life' I climb trees for fun:


    and



    I typically throw/shoot an 8 oz throwbag,



    tied to a 1.75mm line over a limb, pull up my rope, and then I climb the rope. It kinda looks like this (BTW, that's the real Tangle overlooking everything and having a fit that I'm off the ground):



    The question always asked and the problem is how do you get the rope into a tree so high?

    Well you throw it or use a slingshot; here's my version of a slingshot and and the subject of this thread - the pistol grip, trigger release adaptor I made:


    Here it is mounted on the slingshot:


    Here it is ready to go:


    And a close up of the adaptor:


    And here it is in action on YOUTUBE - I didn't do a good job with the camera, but you can get the idea:
    YouTube - A pistol grip and trigger release on a slingshot

    and one other action shot - me doing a traverse:

    http://www.youtube.com/watch?v=6Wza65--3Kg


    I machined the housing, trigger, sear, grip and trigger guard out of UHMW poly and the release lever is AL.

    It can be fired from the shoulder just like a rifle. Since I made the pics, I've added a collapsible stock and shortened the pole by a foot so it's a lot more managable.

    It's been fired about 100 times and have had no problems with it. I designed a unique sear release and am very pleased with it's performance. The device has a huge advantage in accuracy, repeatibility, and ease of use compared to the standard slingshot configurations (hand pull and release).

    Anyway thought it might be of enough interest to post.

    Here's some machining pics:

    This is the raw material on my small drilling/milling machine and rotary table:


    and this is the finished product - the trigger:

    Sweet! Such a unique hobby. Its neat that you took a classic kids pastime and scaled it up into an adult hobby.

    I have to say that you posted a worthy and well done project there . Its in a niche i will never use ( the only way i am climbing a tree is via chain saw then walk up it lol ) but shows some real innovation as well as how handy machine tools can be to other hobbys .
    Make sure you get full value out of today , Do something worthwhile, because what you do today will cost you one day off the rest of your life .

    Now that is a cool toy, I meant tool, that you made. Is there a market for it?

    You need to patent and market that lower unit ,I can see many uses as far as using paintballs to remove stray critters from your yard without lethal effects

    +1 on that,
    Electricians use (although less powered and lots smaller) guns like that to launch pull string over long distances above the false ceiling in offices and such. yours looks to be far more durable and capable of greater distances. So don't think it's just your fellow Tree people will find a use for it.

    Wow, there are some inventive members on here.

    That's killer! Looks like fun.
    +1 on the patent, there are plenty of tree service guys out there that might buy one or two of those.

    Heck yeah! I'd love to have a sling shot like that!

    BTW, if you do plan to patent it, you might want to yank the pictures off the internet until you get it submitted. You stand to lose a ton of money if someone steals your idea....
