A Better Stirrup

[amythntr]

Just suppose.... it folded back toward the stock to be out of the way while hunting, and ....it swung out into position to cock, and locked at a perpendicular position i.e. bi-pod for shooting off the bench? .....Just supposin'
Heck, I'de buy one!!!

If you can dream it, someone can build it.
This is from this forum years ago..
It was built by a fellow named "isis" (no relation). He did this to defeat the clearance issue with turkey broadheads.

...now this is toooooooo cool!

I'm playing around with a rope stirrup right now and find it's better than the stock one because you don't have to twist your back out of line so much... being flexible, the rope (and your foot) can be moved to the right more.

I'll make up a T-shaped steel stirrup later today, shouldn't take long at all.

Here yer go
Afore ye ask, there are two bolts holding the riser on but I had to shorten one and screw it in from inside the rail.
Didn't want to mess up Aging's stock.
All made from aluminium square tube that I cut and then drilled holes for the round tube to go through.
Took about an hour.

That is a GOOD idea brother! The two big holes in the Matrix riser would be perfect for dead ending two knots, with the knots up and the rope loop down. They look to be about 5/16". That size Sectra line has a breaking strength of over 15,000 pounds, and stretch that would be so low at the cocking load of these puppies that it would be basiclly nonexistant.

Gonna have to try this! It would be NICE to dump the weight of the metal stirrip out on the forward end. Spectra is so light that it floats!

Google will give some good examples of that too. It has been done for the intent of the rope dropping out of the way for larger heads too.
Not long ago there was a TV documentary where two guys were using an Excalibur for spearing or tagging large fish, they had a decent rope set up too (it may have been coated cable), something to do with the size of their boots, or perhaps puncture protection due to the fact they were using it in an inflatable boat.

Thanks for the pics snuffbox.

Spectra with 15000lbs breaking strength might be a bit overkill, I used the rope I got to replace my rope cocker, it's originally used for climbing and has a breaking strength of 500lbs I think. Worked fine though should I definitely decide to go that route, I'll take something a bit tougher, better safe than sorry I'm thinking 1000lbs will do.

Anyway, my first design was a fail. I figured, why a T if I only use one foot anyway so I made this:


It does allow you to keep your back perfectly centered but I wasn't able to keep the crossbow down while cocking, the left side, which wasn't held down, kept riding up. It seems you have to use both feet when placed so far apart.

Next I'll make the same thing but mirrored on each side.

If someone can make a decent looking T bar in black to match my nightmare I would be happy to buy it.i bet I am not alone in that feeling.

I don't have nor use a stirrup on Kong my 405! Less weight on the front, no odd metal noise at the shot

How are u cocking that monster VM ? C2 ?

[snuffbox]

I made mine for the Vixen originally,then transferred it to my cut down matrix.
It would originally have been fixed using both of the bolts that hold the riser.
However,it works and does what it's supposed to do.

Overkill wasn't my point. Having the right size line for the hole and zero stretch was. If it stretches any at all, the bow is coming closer to you, meaning that you have to pull higher to get it cocked. Not good!!!

The reason that your bow was tilting is simple: the foot holdown is offset from center! If the load isn't centered, the how will tilt. Physics.

Anything that adds weight or even keeps it close to the same is not an advantage, for me. The one thing that I REALLY do dislike about this thing is the weight, especially the weight on the riser end. Compared to my ancient MQ1, it's forces me to think about getting through the woods instead of thinking about the woods, and what's in them.

Everything is a compromise.

Some cool ideas!

[amythntr]

.....soon I am going to have my crossbow and backpack attached to a drone and lowered down to my hunting spot....probably could hook up a C2 crank that would cock my crossbow before having it descend in my arms read for the hunt!

....THINK ABOUT IT....the technology is here!

There are a host of complications the quickly become apparent as some have mentioned here. There is also the cost, while it is possible to improve the existing stirrup, how much are you also willing to pay for it. There is also a liability issue, by adding a moving part, it will require maintenance. Living in a disposable world people will neglect correct servicing. If one of us has a failure, we have to suck it up, if the company has one, it can be very costly. I couldn't imagine what an Xbow would do to you if it slipped. It's coming right to your face if it does.

In all honesty, for function, form and cost, the factory stirrup serves it's purpose well.

Absolutely right, I just sometimes tend to make something without thinking it through I'm usually wiser in the end and smack myself on the head for being so stupid

Anyway, I played around some more with the rope stirrup and I think I'll stick with it. It's perfect, really. Cocking is much easier now that I can keep my spine and bow centered and it also weighs next to nothing. I don't think any T-bar design can compete with that.
Now the challenge is to find fitting rope, the pink/blue stuff that I have works but it's really not exactly easy on the eyes Can't do that to my Nightmare
