Topic: Racoon like bullet man?
Message: Posted by: afcaballero (May 29, 2017 08:29PM)
Hey guys, who are you?
Id like to see my Rocky racoon flying like the bullet man. Im thinking to make a mechanism with some PVC tube and a spring or elastic tape. But before I start with this proyect, I wanted to ask you guys because I know I can find plenty of knowledge here.
Thank you so much in advance.
Alex.
PD. I dont know if here is the right place to post this, so Im so sorry if I maked a mistake.

The first question to determine what kind of device you need, would be where do you want to move it from and where to? Do you want to have an off-stage assistant with a shoulder fired weapon shoot is across the stage or do you just want it to fly out of a box or bucket unassisted?

You will require an energy source to move it so the choices you have are:

1. Compression Spring (think of the inner workings of a BB gun)
2. Surgical Rubber Bands (think of a sling shot)
3. Gun Powder (think of a shotgun)
4. Compressed Air/CO2 (think of a tee-shirt cannon)

The quickest solution would be to buy a tee-shirt cannon (if it was to be fired by an assistant). If you were to build something, then a compression spring cannon would be the least expensive to build out of PVC. You could activate it with an electrical solenoid.

Here's an Idea! You could build a cage labeled [b]DANGER - WILD ANIMAL[/B] and have a CO2 powered device or compression spring device fire him up in the air when you opened the top of the cage then you catch him and go into a Rocky routine. It would look like he was trying to escape the cage. Now that would be funny!

Gary, thank you so much for your reply. You are the best; what a wonderful ideas!
I have been studiying electronics for about two years, and I can make any trigger device, I mean using selenoids, servos, motors, etc., I can even do it remotley. But my raal concern is, as you said, to find the better energy source. But the CO2 idea is simply wonderful, I will also experiment with sprigs, as you said.
And the cage labeled, is also great.
Again, thank you so much for your replay, your time but mainly, for your ideas.
Alex.

I just launch Rocky manually. I get great distance. The benefits of pitching him for so long.

There are some great ideas here:

Hey Gary, thank you so much again. I make my first prototype today, with a pvc tube and elastic bands, and work very well. I have to do some adjustments but almost get what I want. I will make an old bullet man cannon that launch my raccoon but works remotely. When it's finished I'll show some pic's, vid's to you. Again, thank you for everything. Best regards. Alex.

I was digging through my Rocky stuff and found two additional Rocky props that you might find interesting:

1. A potato chip bag with a racoon tail protruding out the opening. Inside there is a battery powered ball that rolls around causing the bag (with the racoon tail) to flop around on the floor. It looks like he is eating the potato chips and will cause the audience to do crazy with laughter.

2. A similar small burlap bag with a racoon tail protruding. There is a battery operated module enclosed with-in but I don't remember exactly what it does. I think vibrated and made sounds. I put fresh batteries in it to verify but it didn't work. Sometimes electrical items just die from old age.

3. While I was waiting for my wife to finish her doctor's appointment yesterday, I put some ideas down on paper. You are welcome to them if you want.
(Note: I came up with these ideas before finding out about Randi Rain's (Rain Cloud Magic) Rocky Launcher. So I didn't steal her idea.)

And as always, I'm here to consult if you need to bounce any other ideas off me.

I found a spring that might work here:

Here is another spring that might work a little better but the firing tube would have to be larger than the spring's O.D. of 3.625". A 4" PVC firing tube would work for it. I am not sure how far a single spring would launch Rocky but they could be stacked to gain more power. I don't know what your venue is or how you need to launch it.

Thank you again, Gary. I decided to use elastic medical bands, they work perfectly. Best regards.

How are you triggering the release?

Have you ever done something then wondered why you did it?

I put a $10 offer on those big springs just to see if they would take it and ***, they did, So I guess I am going to have to make a Rocky Launcher. I don't even do Rocky anymore but..... It will be interesting to see how far he launches with a secondary spring. I usually get 3 or 4 feet with his internal spring but sometimes requires a little boost.

Is anyone interested in one? I have the springs to build two units. Oh, what the heck! This will be fun.

Stay tuned.

Hello Gary. Answering your first question, I will use a servo motor that pulls a pin that release a cord attached to the medical elastic bands. I think your idea of using a spring is very interesting so, please let me know how your proyect is running. Best regards.

I once saw a performer who did a similar shtick with a stuffed monkey. He had apparently replaced the core of the monkey's arms with surgical tubing. To fire, put your thumb in between the joined hands, then stretch and fire like a rubber band. The tubing retracts back into the skin of the arms, so it is not seen.

Hey Gary, how are you? I wanted to tell you, after a month and a half, finally finished my racoon launcher. I decided to use an extintor loaded with air, some pvc tubes and an electric valve. I also put some leds on all the cannon. Both the launcher and the leds are controlled by a remote control.

I thank you so much for your time and ideas.

Best Regards,

Alex.

How far does it launch him?
Message: Posted by: randirain (Jul 30, 2017 01:51AM)
I am the one who built the box with the picture of Chris.
The way it launched was...
There was a box inside that had a bottom that moved up and down. The bottom piece had flanges on two opposite sides that stuck out the slots in the sides of the box. On the out side of the box, was two long springs anchored on each side of the flanges, and lapped over the flanges. That way, when you pushed on the bottom, you are pushing on the tension of the springs. The top of the box had double doors, where one laps the other. A motor with an arm would turn to put the arm on top of the doors, holding them shut.
So you compress the rocking into the box, which also pushes down on the spring loaded bottom, and the doors are closed, the arm is moved into place, and you're ready to go.
With the two springs and the spring in the puppet. It really did shoot like it shows in the picture.
Hope that all makes sense.

Hey Gary. With 60 PSI of air pressure it launches 5 meters, with 80 PSI launches 7 meters. The extinguisher can hold more than 150 PSI but I've not done any tryings with this maximum pressure. I just need between 4 and 5 meters.
Best Regards.

I want to tell you, Randy, that you are very talented; this box is wonderful, outside is beautiful and inside is simply marvellous. I admire your creativity. Best regards, Alex.
