Gort's Proton Pack (Combustion Backpack Launcher) + Videos!

[sgort87]

Well here it is guys, the "Proton Pack" (Think Ghostbusters) AKA: CBPL (Combustion Backpack Launcher). There's been a lot of hype about this launcher and I hope it lives up to what everyone has been expecting/hoping.

First of all I want to thank Mr. Plow for all his input on this launcher and many other things. I'd like to thank Darth Tater (Spudtech) for inspiring the original concept of the backpack combustion many many months ago in the middle of the night while we were quite delerious and came up with some very off-the-wall stuff. I'd lastly like to thank the many many other people who were there to go over all sorts of other details and suggest things to me.

My objective was to come up with a combustion backpack lanucher (no others exist) that was easy to operate, offers fast potato breech loading, fast venting and fueling, and interchangeable barrels.

The gun uses a 24 volt solenoid actuated 3-way valve meter pipe, matress inflator (check valve inside chamber), 12v mixture fan, stun gun ignition, and rechargeable batteries (recharges without opening the box). This chamber is mounted to the back and has a hose that attaches to the bottom and leads to the barrel.

The CBPL barrel system took a lot of thought. To my knowledge nothing quite like this has ever been done before. The controls are located right on the handle. The tiny switch above the red button on the handle controls everything. Up is solenoid and blower on. Down is fan on and stun gun ready. The button controls the final step of the stun gun. There are 2 on/off switches on the gun. One is on the chamber and one is on the back of the barrel track. Both must be on for it to operate.

What goes on here is that the hose connects to the elbow, bypasses the bell reducer and goes right into a female 2" cam-loc. The reducer holds the 4" pipe to the 2". This 4" pipe is basically a track for the barrels to slide in.

The secret to this is that 3" fitings fit inside 4" pipe. So an insert was made from a 3" coupler with a bushing on each side of it that fits in the front of the track and is clamped in place with a small wing screw. The bushings were hollowed out a little to allow the barrel that fits inside it to slide freely. This barrel then has a male cam-loc fitting on the end of it which locks into the female end. I have 3 inserts that allow for 2", 1.5", and 1.25" barrels. I will be making 2.5" and 3" ones soon.

So here's the cool part of the loading:

And here's the golf ball barrel on it:
EDIT: I also got the pipes for my GB barrel from my most favorite forum member, Pimpmann22...

After the countless hours and money spent and/or wasted on this I hope this launcher proves to be pretty good. I will do more testing and video soon.

Edit: New pictures with new electric box and LED fan:

That as to be the sickest thing I have seen yet.

[sgort87]

Haha, thanks man. It's hella fun shit firing this thing!

[Rambo]

You may try to make it auto combustion.It will turn in to a jet engin or it will work properly. http://www.spudfiles.com/forums/viewtop ... 78&start=0&

That's awesome! Where did you find that huge flexible pipe? I also love how simple your interchangable barrels are, no threaded fittings at all. Not to spoil anybody's fun but, tif that explodes (which it probably will just rip the hose off) it will cut into your back. I love the concept of the breech too!

[sgort87]

For someone of your post count I'd expect you would know these things don't just explode. And especially not with a 1x mix. Besides, my back is guarded by more than enough padding and metal strips to block anything this can toss at me.

The hose, I got that off of http://www.mcmaster.com It's a favotite for specialized parts. Quite big on Spudtech. Dunno about here. It wont pop off. I double clamped each end and needed to hammer the giant hose barb into the hose. It aint comin off without a looong fight.

And thanks about the barrel system. It has proven to be quite useful. The no need for threading barrels on makes life so much easier.

WOW...... im speachless

That has to be one of the COOLEST cannons ever made,I remember checking it out on your web sight.

[jrrdw]

Gort for president! And all his contributing friends for caginet posstions!

Great job!

My questions are: How long in total did it take to build?

How much do you have invested?

Wil you be building this for sale? If so, how much?

I don't have the extra money to buy one, if your going to sell these, i just want to know.

Once again, great job!

[frogy]

That thing is AWSOME, that's probably the coolest combustion ever...

Great job man, my question also is how much did it cost?

Thoose 3-ways are normally about $50 alone

[sgort87]

The parts on the gun and barrels cost me around $200-250. I have been thinking about selling them but I don't think so many people would be willing to pay $300-350 for this although it IS so cool to have.

This gun spent a lot of time in design as many of mine do. The barrel track was the hardest part but since I spent a lot of time thinking about it I was able to get it right the first time with the exception of a few extra cuts here and there for comfort and such.

You guys may see an update on this soon. Maybe even a Proton Pack II.

If I decide to sell a couple of these I will need to make sure this doesn't do anything weird like at the driving range in KY where it overheated.

I tried to look at the video, but it said "This pic does not exist" is it just me? Or does everybody else get that message?

[Boomer_]

i got it, but gort i gotta see that thing in real life, im not sure i wanna use it after the Mr. plow story though.......
