Hey, guys, welcome back to DIY Films. I know we haven't done tutorials in a while, and I'm sorry for that. But it's just that...well, I just couldn't. This week, to come back, we're looking at Parker's Tutorials and seeing that he made a grappling hook gun. I actually challenged myself to do better - to try, at least - and I did...try to do better. And here it is (see way down below). Pretty good, huh? The gas container came from a BB gun. You have the hooks that open when the grappling gun fires. And, yeah, the gun is actually pretty cheap. So let's get going...
Case File #1: Grappling Hook Gun Requirements
- gun handle
- the gas container from a BB gun
- PVC pipe (regular)
- 1/4 inch-diameter PVC pipe
- a part from an older aerograph (You can find this in many stores.)
- plumber's epoxy
- strong glue
Case File #2: Grappling Gun Housing
Here, as you can see, I cured the front part of the aerograph. You see it kind of looks like a motor, in a way, because it has grooves. I cut off the front of the aerograph. The other 2 pieces were parts of the aerograph cap that screwed onto another aerograph part. And then there was the nozzle (not pictured, also removed from the grooved aerograph piece) that was at the front. Now I really don't suggest going out and buying an aerograph for your grappling hook gun. Aerographs are expensive, like $15, and not all of them look like this. So, if you really need a piece for the gun, cut it out of poster board or something, then cut in the grooves. You don't have to put in the grooves, remember this is all up to you. I'm just doing my grappling gun my way, the way I want to do it. Yeah, so this is how I'm going to do it, with this as the motor.
Now I cut these shapes neatly in a piece of PVC pipe with a hacksaw. Then I put the little metal gas tank in the pipe. And then I lay out the motor next to the pipe to sort of see how the grappling gun would look. Then I glue on the metal BB gun gas tank. Make sure the glue you're using, hot glue or something, is not too hot, because past 50 degrees (Celsius) the little gas container explodes. So be careful. My glue is liquid glue. Because the tank is iron, I'd rather use it than hot glue, because hot glue doesn't hold well on iron. So I use liquid glue and the part doesn't come off - it's really stable.
So now I take the toy gun handle and place it where I want it and mark the spot. Then, with a powerful glue, I glue the handle onto the PVC pipe. I put epoxy on the grappling hook gun where it needs it: in the cracks, etc. Now we have to wait until the gun is dry, if it's not dry yet, and sand the heck out of it. I use sandpaper to sand it down. It'll turn out pretty well, and that's what I want.
Case File #3: Grappling "Hooks"
For the hooks, I found a technique that was pretty good. I took some plastic forks and cut off their heads. They're going to be like the folded hooks, what's supposed to extend and grab when you shoot the grappling gun. So the "hooks" are folded like that...I'm still waiting for the epoxy to dry, and I used some more glue for the hooks. I'm going to put another hook on the top and another on the bottom of the grappling gun. But it's up to you how many hooks you want to put on yours, whether 1,2,3 or 4, maybe 5. I think it's pretty cool like that...
I actually ended up making only 3 hooks; the 4th one wouldn't fit, because there was no place for it. I also put a cap beyond the hooks (at the end of the barrel). So we're finished building. Now we just have to paint the grappling hook gun. And here it is:

Thanks for reading this tutorial from DIY Films...I hope you enjoyed making this grappling gun. I did, 'cause it was cheap and I didn't spend my money...much. See ya!
