gun rigs for disabled hunters

I am a quad in a chair that hunts, could you put a trigger bar on the rifle witch he could pull with his arm.
Also are you building this shooting rest so he can use it from his chair?
There is disabled sportments site that may be able to help, will try and find it and post there site for you.
Cheers rottenfufher.

Yes, I'd like to come up with a rest that clamps on some how so he can clamp it on his power chair or his manual chair. I rigger up a .22 semi with a trigger extention (very crude) and mounted the gun on an old video cam tripod. This work well for him but I need to have the rig mount to his chair and be able to with stand the recoil from a deer rifle.
i am fairly good with mechanics, welding, and creations and the like and would love to help out, i am not in a chair myself but have recently been added to the disabled list as a result of and at work accident.
for trigger movement you could easily rig a trigger bar to a remote actuated solinoid on a microswitch that would require very little "movment" to function of course you would need to build in some sort of failsafes or safety switch.
as for the rest a simple vise attached to a reinforced section of the chair with 1 or 2 small air shocks would help absorb some of the recoil, but if using a semi you will want to limit the amount of absorbtion due to the action needing that energy to cycle. *also look at reinforcing the "wheely bars" on the back of the chair that stop it from flipping backwards*
how are you planning on sighting?
if you havent got a plan yet might i suggest a laptop with a weather resistant cam mounted on the stock where your eye would normaly have a perfect sightline.
just a thought
Like if i can help out in anyway let me know
also when/if modding the chair "adding rests etc" ttry to ballance out the weight load evenly or counter blance it on the other side with extra weight

The hardest part to wrap my mind around his how to temp. attach what ever we build to the chair. It would be nice if it could be transferred between his manual and power chair. Once I figure out how to attach a rest/ frame/ rig to his chair then we can attach a gun vise and rig up a trigger pull. I am thinking of using our grandfathers old 30-06 semi that is still in the family.
I have found some pics on the net but they just don't show how the framework attaches to the chair.

depending on how the tubing the chair uses for a frame is layed out you can weld short bolts to the tubing in the exact same place on both chairs and then use a wingnut to secure the rest/vice to the frame rails of the chairs.
if the tubing isnt in the same spot then you can make a secondary brace that welds to the chair permently and has the bolts welded to it identical and use the same wing nut or knurled nut to attach it on each

The one I built for rottenfuhrer was built in one night in a friends shop. It's built from 1" square tubing and is fully adjustable to fit rifles with magazines that hang out the bottom. It can swivel from side to side and I installed a turnbuckle with with four small rods welded to it so he can adjust the elevation his self.
I also built a trigger actuator for another buddy of mine but it doesnt use a solenoid, it's basically a long rod with a bar that he can pull towards him and fire the rifle. It works great and it improved his shooting a great deal.
PM me if you have any questions.

How about one of those Garand "winter triggers" ? If he has any hand motion at all (seems like he does if he has a manual chair) he should be able to squeeze that big lever easily. Making a rest would be more difficult however, the best, but far from the simplest idea I can think of is to miniaturise the "wheel" systems that they use to aim artillery pieces, basically a worm screw that gets turned with a wheel and a handle attached to it, one for windage, one for elevation. Anti tipping bars on the chair would be a must, and unless you make the rig out of ridiculously lightweight materials you will need some sort of counterweight behind the center of gravity of the chair to balance things up so that the extra weight doesn't cause the front wheels to dig into the ground and immobilise the chair in the process.

Wow, this is a very interesting project. Here are a few thoughts that immediately popped into my mind.
1) Optics - I would try the Elcan Digital Hunter (approx $1200.00 I think). These have a 'video out' port. I've seen a lot of 'in car DVD players' at Costco that come with a pair of screens that hang over the front seats for the kids to watch. They are rather inexpensive. Mount the screen on the arm opposite the gun. The scope would be more clear and more accurate then a video camera. Probably more recoil friendly, and less bulky as well. A little pricy too, but your cousin would be able to capture his kills on video through the scope!
2) The Mount - Recoil - As was mentioned earlier, use shock absorbers. I keep thinking of artillery pieces, tank guns, and machinegun mounts.
3) The Mount - Movement - I would keep the mount pointed mostly forward to keep most the recoil rearwards. For small lateral and elevation movement (40 degrees maybe?), I would look into small servo motors attached to power screws.
I friend of mine is a remote controlled airplane nut. He's showed me a lot of the hobby sites that he gets stuff from. If you used the board from a plane remote control you could create a joystick to operate it similar to whatever he uses for his chair. He could line the chair up, then use the second control to adjust the rifle and take the shot. The servo motors allow for precision movement, as they are designed to control flaps and stuff on the planes. They were relatively inexpensive. Would this work given the specifics of your cousin's disability?
4)The Mount - Chair - I would see about making a precise fixture that can mount on his chair. If you needed to make a seperate fixture for each chair, I'd do it. Design them so that the rest of the mount would attach to either. (think of an aimpoint, and the dozen different mounting options you have for it).
5) Trigger - I like the solenoid idea. There would be several buttons on the airplane remote, one could be used for this. As far as safety, maybe you could put a delay on it (ie - the button will fire after being depressed for 3 seconds straight). So inadvertant taps will not set the rifle off. Maybe have another switch on the control give your cousin control of cocking the rifle, so that he could chamber the round on his own. Also, another switch could operate the rifle's safety.
The radio control keeps the wires down, though you would probably want the trigger wired in. As for the design of the switches, etc - these would be specific to your cousin's capabilities.
This may seem like a lot, but it would give him almost all control over his shot; his kill.
