trigger for big shot

[opposablethumb]

MLove you know those triggers well, I think key is to cut that rubber hand grip off the pouch and connect the official trigger string. I use small D's to connect.

yoyo - what are the D's you are referring to?

I use to attach my panic snap to a quick link attached to the webbing on the pouch, but it altered my range and accuracy. Now I just attach directly to the webbing, but I am concerned about wearing the webbing out before the whole assembly of rubber, etc. reaches the end of its service life.

Here are some shots of my Big Shot set-up. This system has been working reliably for many months, consistently launching a throw bag over targets 70 to 100 feet up. The archery trigger ($22.00 from Dick's) comes with a piece of threaded rod which attaches it to the wrist strap. I discarded the wrist strap and bent the rod so that I could connect it to the hook on the tie-down strap. Then I covered it with some black silicone tape. Rather than remove the pull strap from the pouch on the Big Shot, I installed a loop of some 1/8 inch vinyl coated stainless wire for the trigger to hook on to and I wrapped that up with some silicone tape. The tie down strap is is from a set of three which I got at Home Depot for about 9 bucks, if I remember correctly. The bottom end of the tie-down connects to a prussic which is wrapped on the bottom of the pole. when I put it away, I break the pole down and wrap it all up with a couple of velcro straps. Neat, and easy to carry.

"...Trouble is to find the correct 2mm cord for that use...

Not a problem. I used 7/64" Amsteel Blue (1400 lb MBS) because I had it, but would have used Dynaglide otherwise. Both are Dyneema. Strong and abrasion resistant.

I used a double fisherman's knot to tie the loop through the BS's pull strap and used whipping twine around the strap to capture it. No permanent mods to the BS needed.





Very little wear on the amsteel after many shots.



Looks like we were posting at the same time dogwood. I also used a prusik (or a few wraps and a girth hitch) to secure the tie down strap to the pole bottom. I put a few wraps of silicone tape around it to make sure it couldn't be knocked loose in transport.

I'm not sure how this idea got out here in the first place, but the tie down strap - trigger combination is the bee's knees as far as I'm concerned. Simple, cheap, reliable, and easily repairable.

Awsome ! Thanks for all these details, that's a delight !

 

[dogwood]

Come to think of it, I bet it was Yoyoman!

 

[monkeylove]

That was my first thought also. I know he invented my Uni drum and I use the heck out of that thing.

I think the "D's" are visible in the video but when I get home in a few days I'll take some close up. I use the official string that comes with the trigger.

How's it working for people?

hows the trigger workin for u? have u had a chance to play around w it?

 

[Bradypus]

Just received the TRU BAll Outlaw.
So far i love the design that looks handy with its curved trigger and above all its attachment ring that will make the link to the rope quite easyer than the bar system of the Patriot.
I also love how light it is.

But i don't like the "tested at 100lbs" and not 200.
And i don't like neither that it is packaged without the allen key needed to adjust the sensibility.


Gonna test that soon

Hugues, good to see you are getting it the way you like it.
In this video if you look at the first few frames (I'll post the link below) this is where I have cut the handle off of the bigshot pouch and attached the small "D" rings by sewing them in place. The bow string loops are then clove hitch and or girth hitched to the rings. This way not a single ounce of extra, not essential weight is being added to the moving launch of the shot.
I think it is in another video but I also alter the tie-down so that the trigger connects directly to the grab link of the truckers tie down, this gives me about 8 inches of additional pull and makes it a little cleaner and lighter.

Link to Archery Release Cord used to connect between the "D's". (Guess I can't put more than two links so search ebay for Archery Release Cord)

Link to Tru Fire Patriot Jr Power Strap Black Release PT-JR, I just ordered another for 13.00 including shipping.

Thanks Richard !

I'm thinking about having a good "pimp my shot" moment and sewing the bigshot pocket is in the air for sure. I could use D-rings, but as i also got some ultra resistant but really ligh webbing. It's really thick (3/4mm) but not large (10mm) so i think it will be able to take the trigger cord without any deformation.

I plan to attach this cord thanks to splices. It's a bit more challenging than making knots so as i've never done any splice i'm excited by the idea.

I plan tu attach the trigger to a pulley cause i want to do a haul system. I want to do it thanks to a softshackle. Home made of course ^^

I still hesitate between a rope or a small webbing for the tension rope... Rope is exciting because i would make an other splice for the end attachement, but a sewing may make a non bulky end to be able to push allmost to the bottom using a little pulley.

I want to drill the bottom ferrule of the shot pole so i'll be able to pass a rope loop through it. In wich i'll put two others softshackles. One for the tension rope or webing, the other for the duck i'll use as stoper.


Something like that.

Bradypus,
just two comments in regards to your post again it sounds like you're making some great progress On the way you like it.
that truck tie down connector does provide a 2:1 mechanical advantage but some is lost due to friction. Also connecting the other end of that tie down with the provided hook is very easy simply by poking a small hole in the rubber foot of the bottom pole section.

 

[Bradypus]

I was thinking indeed about the truck tie weebing solution, but it looked to me a bit heavy and full of friction for sure, and "only" 2:1. That's why i'm going to the 8mm rope or 10mm webbing + pulley & duck that would provide a 3:1 z rig, less friction and less weight (as i allways got a hitch climber and a pinto in my set and the duck is quite light). So all in all it looks better to me.

The only problem is having to drill the ferrule. The hook option is easy to handle for sure, but heavier than some rope. Our gear is so heavy that each gramme won is kind of a victory...

 

[gmcttr]

In my opinion, the 2:1 is plenty and the 3:1 will just add a longer length of rope to drag around and tangle. I politely suggest not overthinking the setup.

 

[Bradypus]

Good point. Plus overthinking can be one of my default that's a fact

 

[dogwood]

Good one, Ugo!

Hi there

I wanted a solution letting me choose if i want to use the trigger or my hand. i came with this system cause softshakles are fun to do, strong, inexpensive, light and of course possible to open to add the hand grip if i wish.

The yellow rope is a 2mm polyamid one. Pretty strong so far and works like a charm with the trigger.



The hauling system is still based on a Z rig. I had fun to do splices, it looks hugly but it seems strong enough.
1 TRU Ball Outlaw, not as well rated as the Patriot but it looks to be made exactly the same way with same components except it doesn't have a long tail but an eye easier to link.
2 A marine grade pulley, tiny, light but strong.
3 A dirty splice ^^'
4 A long softshakle
5 A Duck
6 Two smaller softshackles
The green rope is an 8mm marine grade, very light and pretty strong.

I use 3 pole extensions cause it's easier to carry the bigshot in a travel bag, i can use the hole of the last ferrule. Trouble is it's drilled in the oposite side of the shoot axis.

That's why i use the first softshakle : it goes around the pole to allow to fix the duck right in line with the slings. It is quite quick to set : 10s are enough. And it is as fast to unset.

The system looks quite streamlined and comfortable to me, plus it is light, easy to pack and above all effective. I had a lot of fun to make it and use it, which is important to me . I use it for two months now and i'm really happy with it. No problem with the rope running on the ground, it is not a big mess. Out of the box the trigger is very sensitive, it can be changed for a stronger resistance, that works but i prefer in fact the light sensitivity.

Sorry for the bad quality of pictures i'll do some more if needed.

Thanks for the inspiration !
