big shot trigger

Here's what I've used for the past year or so:

Unfortunately, they aren't commercially available. This is my own design and I built it in my shop.

And, yes, I shoot it 'horns' up and out of hundreds of shots, it's never 'blown' back in my face, even when the throwline caught on something and even with the pouch twisted around three times.

There's only two in the world that I know of, mine and a one that belongs to a friend that built one in my shop last year.
 
Yes, but the sheet is 2.0" thick. A 1.25" hole is drilled in the center and the entire piece is mounted on a mandrel on a vertical rotary table and manually milled to outside dims and then slots are cut, holes are drilled.

Trigger, sear, and the release lever are manually milled on a horizontal rotary table using a complex jig and dims.

Probably would be ideal for injected molding techniques but I don't have an injection moulding machine and I do have a milling machine (and lathe) so.....

This Is what I use.
Got the release from Tractor Supply for about six bucks.
You hold it when releasing, so it doesn't flip back like the the Wichard.
I use a 3' + 6' pole combination, 3' on top, 9' of pole to work with.

Yep, that's the cheapest and best trigger, imo. I've used them for years. But I don't use the throw line connecting link.....good idea. I have to remove the rubber tube on the BS trigger, or slide it to the side...and file the trigger inner area a bit so it releases the BS webbing every time.
 
Hey fellas, first post but been reading for a while. This is my set up, been using it with a trigger for over 12 months. Using a Micro Traxion self capturing pulley, a spinker quick release with a filed down pin and release arm. Its never prematurity released yet only takes a light pull on the zip line to let er fly.
I must say the above pistol grip version is truly innovative and credit to the engineer.

Thread necromancy to add newer configurations.

I've really enjoyed using my Big Shot line launcher after making some modifications. I wasn't strong enough to hold tension and aim very well at the same time, so I made a 2:1 pulley arrangement with a prussik on the end of both legs. In order to get enough tension for long shots, I had to shorten the strap on the cup. I added a trigger using an inexpensive panic snap usually used for dog leashes.

I've been using it like this for several months with no problems.

To cock it, I hold the pole vertically between my elbow and side of my body. I push the lower prussik all the way down, and the second one far enough to get the required tension for the shot. I'm always careful to keep both hands below the trigger while aiming and releasing the shot.

I am enjoying seeing how everyone has rigged their Big Shot, so I will share my setup too. I use a Petzl Micro Traxion progress capture pulley connected with an XRSE carabiner to the old, over-priced trigger that I don't see for sale anymore. (Can't remember what it was called.) I anchor the rope to a hook I cut off an old tie-down strap, and I drilled a small hole for the hook in the rubber boot so it fits very tightly. I normally use two 4-foot poles and always shoot with the pole on the ground, but for those higher shots, if I need a lower perspective for aiming, I can easily move the rubber boot assembly to a 6-foot pole and save myself from sitting on the ground and twisting my neck. This has worked well for me for years, but I do have an occasional annoyance getting the trigger pull cord caught in the pulley.

I've used the Bigshot rig/ setup below for years now - cannot take credit for the trigger idea which is due Dan H at ClimbingArborist. The archery trigger is from a bowfishing setup I think it was. When fully pulled with the help of the pully setup, it's a scary amount of energy stored in that rubber band all right. But accurate - I usually can manage a 2' X 2' placement at about 40 - 50 feet pretty consistently because I'm not straining on the pulling bits. Helps accuracy lots (and I most often need all the help I can get in bushy confiers). Cheers

Never saw a horse panic strap till now (all our Alberta horses are calm?? :-) ), but I'd say that the archery trigger releases are purpose built for releasing a big pull with minimal jolting (it would affect bow shooting accuracy). Mine releases really smoothly even after years of use. May be more than one way to get to the same end though. I just discarded the wrist band part of the thing when I bought one.
 
When I copied Moss's archery release probably the only thing I in passing changed was to put serving on the throw line loop so it would behave properly in the archery release - nothing new just copied the archery guys, but I now read about others having had interaction problems with a throw line loop and an archery release.

Where have the years gone? holy cow

judging by the photo I used the same archery release but mine was anodized black $20 or $25 IIRC 10-24 or 10-32 threaded mount

losing weight on the pouch assembly puts more of the power into the throw bag BTW

The archery trigger (apparently called a dual caliper type) I used releases against a small metal ring (tiny screw closure quick link). I just figured it'd wear better than a cord loop. Maybe a cord loop would pull against the sides of the paws on the trigger more - a tensioned bow string is more linear against the paws? I did wonder about the holding ability but the store said they used them on hunting bows at 75 lb draw with no problems. Hadn't seen Moss' posts on this, but trigger is a good idea. The pulley really helps me get consistent shots off. Haven't tried a Notch trigger. Cheers all. Where have the years gone indeed. Wow.

Just for info - serving is tiny spectra parallel core braided cover "rope" (one of my two spools is marked 0.026" dia) that you wrap like endless prussic coils on the area you want "serving" on. Saves wear on the bow string and removes a bit of the cutting into your fingers and in our case gives a bigger more solid profile for the archery release jaws to grab


Moss's setup was a pvc pipeT assy that held the trigger parallel to the pole but offset a bit away and the T was anchored by a prussic on the pole. To tension I push the T down and it pushes the prussic like a tender. I have a top half pole with the head and pouch and bottom half keeps the T trigger assy always on it. lower half pole sharpied in inches for shot strength repeatability

edit - autocorrect plc??!!
