Getting rope or string over a tree.

[MossRoad]

I've seen arborist slingshots used before. But they are band powered, not air powered.

I second the potato gun... :laughing:

yep, use my son's bow with arrow. Puts the string right over the limb , etc,.

Now that's what I always use. I just use a plain target tipped arrow with fishing line tied to it. No special fishing arrow required.

Although the air gun looks like more fun.
But I'd be careful with the air pressure not just about the force of the projectile, also as too how much the plastic pipe and connections can withstand.

More or less, but just air powered. But if you put some weight inside the "rocket" and charged to to say 90 lbs.. It might kill from blunt force trauma at close range. I sure wouldn't want to get hit with it. The empty PVC rockets move pretty fast at 30 lbs of pressure.

A friend of mine made a potato gun several years ago. Used a twist igniter and hair spray sprayed into the chamber. He lived in town, so to test it he shot it into the back of his garage. The impact pushed the nails out and left him with flapping boards along the back wall.

I would not want to be shot by one either.

I do like the pressurized air better than combustion. Much safer.

My kids and their friends used 4" PVC and hairspray for their long tube potato guns. Man they sounded like a gun going off and could sling a potato a million miles; well, maybe not a million, but with great force and velocity and huge bang noise factor. They'd peel some of the potatoes and not others and jam them in the end of the pipe and then light the whatever they used as 'fuse' for the combustion, and boom, away went the potato, never to be seen again. Pieces, yes, potato, not so much. Hair spray, costly, fun factor priceless.

Yep, as long as you keep the pressure low like I have done. It seems like 30 lbs is more than enough to scale the trees we have around here. Might need more for some of those giants out west. But I wouldn't want to put really high pressure in the thing to leave a good safety margin. One day at the range a guy brought a spud gun, and loaded a tater and slapped down a pepper popper faster than I have ever seen a 12 gauge load slap one down. That tater is going slower than a load of shot but weights a heck of a lot more. There is some real energy being transferred there.

[Navy story/Salty Sea Dit] So a light weight, air powered, scaled down version of a "line gun". We'd use them to fire a rubber ball tipped projectile with a looooong piece of parachute-cord, from one ship to another when the wind was too strong for a heaving line or bolo.

Arrrrrr! irate:

I've used a bow and arrow with fishing line tied to the arrow to get a rope over a tree in the past. Then I used the fishing line to pull a heavier cord and then used that cord to pull a 1/2 cable.

The tree pro I know has a sling shot...but I suspect the use of drones is in the future for this type of task if not already being employed...

I used my quadcopter to measure the height of a tree.

This looks a lot safer than what I saw a neighbor try years ago; parachute cord with an old axe head tied on the end, being whirled around like a holo before releasing it. I got the heck out of there so I don't know if they were successful or ended up in the emergency room.:shocked:
