Updated VIDEO 12/16/09 Jeepkahn's Collection...

Unread postAuthor: jeepkahn » Wed Aug 19, 2009 9:29 am

This post is so that all my launchers can be found in one location (and linked in my signature)... Other prolific builders may want to consider something similar...

As I add more to the collection I will add them to this post...

I will be doing a video to be posted here as well that will show ALL of them in action... as well I'll be editing throughout the day the specs for all cannons listed...

But for now, here's the pics...

Given my Aspie disposition, if I ever decide to get into building hybrids...

My thoughts on the video is to have all the barrels preloaded and to fire each one at a clean piece of 3/4" plywood(not per shot, but start with a clean sheet), and the video should be about a minute:30.... To really show the benefit of interchangeable barrels on the modguns...

And to show how effectively I could take down a mob of Zombies... :D

Very nice guns.

Also, in the photo of the Decimater, are they passionfruit vines in the background, they look very much like them and my parents are actually passsionfruit farmers

Nope, the sticks are tomato plant stakes, and the field behind that is tobacco...

Your very first Pneumatic looks very much like my Mouse Musket, except the musket had the barrel end at the end of the chamber.

Here's some pics of Decimater with sleeved barrel, muzzle BRAKE, and new fire control layout...

The Ghetto Brake mount is gonna be replaced with set screws...

decibrake.JPG
Do I get Ghetto Points???? It is actually quite effective in comboination with the overall weight of the gun...
decifirecntrol.JPG
Yeah, i know, overkill with a 1/4bvpiloting a 3/4QEV piloting a 3/4QEV piloting a 1.5" piston, but at least I can look straight down the barrel now... And it's FAST!!!
decipov.jpg
Quite Impressive I think....
decinew.JPG
Can you tell I like Tripods under BIG GUNS??? This tripod puts the gun pivot at about chest level for ease of aiming and firing...

And while I'm updating this collection thread, here's a coupla pics of the new firing control/vent/stock setup I put on the copper cane posted in the OP...

Full port BV venting the coax's pilot volume through the 3/4" Tee/3"nipple handle, the rear leg of the the tee has the homemade stock... ergos are just about perfect for me, and no NOTICED loss of performance from switching from qev/blowgun to bv, prolly because the pilot volume shrunk with this layout, and pulling the "trigger" is prolly less than 1lb of pull required... Next nice day I'll get some vid's of firing it...

The Muzzle blast in that video is just Beautiful. There needs to be a different angle on that so we can all feast on it.

Very sweet.

Does the muzzle break have any effect on the recoil of the cannon? Or is it just on there for a badass looking muzzle blast. Either way, it's still pretty cool looking.

That looks nice indeed!
The handles look good, and I like how you vent through the handle as well.

The brake is quite effective, before the brake it would stand the tripod on it's rear leg(even when held with 2 hands) and that video I'm firing singlehandedly...

And Yes Jack, Look for a Longer/highquality video, with destruction footage in the near future... :D

And Psy, I went back to single qev and trigger on the decimater because with the brake being so effective I wanted to not use up so much volume on dual qevs... but it still vents through the handle...
