My latest Combusion

[Woody]

This is my latest cannon. Let me know what you think

• Cam Lever breech loading concept
  
  Duel stun gun ignition (advertised as 200kv however I highly suspect that as inaccurate)
  
  12v brush-less fan in the chamber
  
  4" 20" SCH 40 Combustion chamber
  
  Barrel shown in some of the pictures is 1.5" 5' SCH 40

----------------------------------------------------------------

I scraped this spud gun since it had I couple flaws and I wanted to incorporate a couple ideas into it. I have the new one made now, but I'm gonna wait till later to post so I can gather some good damage pics and possibly paint it as well.










Frozen potato spud was used for ammunition.





The arrow went about 2.5" into the maple tree. It was a cheap target arrow made out of fiber glass. All though you can't tell in the picture the shaft was split into a couple dozen pieces.

Nicely done, one small thing unrelated to your launcher though, perhaps resizing your pictures would make them a bit more forum friendly

[Woody]

Sorry about that. I usually set my camera to a lower resolution when I plan on posting the pictures somewhere but it went over my head. I might manually do that later though.

[jackssmirkingrevenge]

While you're at it, since your launcher is clearly capable of wreaking havoc, damage videos are always appreciated

When you say 200v stun gun, do you really mean 200,000v?

[Woody]

Yea that's what I meant. Thanks for pointing it out.

[paaiyan]

Haha, just making sure. Because 200v would make for a very very small spark.

You can take hi-res pictures with your camera, just resize them with one of the many photo tools that are available, then post the resized, smaller pictures.

Looks solid but a good bit utilitarian. I assume you are opening the rear cap to air out the chamebr after each shot. You could easy install a pvc ball valve here to more easily perform that function.

Not a bad effort though. Welcome to Spudfiles!

Very nice job on the cannon. One small thing, but it would look a lot nicer if you hid those wires coming from the conduit box. You could use some flextube or even air hose to do it.

As for the pictures, if you post them using the Spudfiles uploader, it will automatically resize them server-side into a thumbnail, which will speed up this page's loading time.

teh lag it burns...

Nice gun mate, i like the colour scheme, damage vids are a must!

[Woody]

Ok, Re sized all photos to 30% width and length so loading time should no longer be a problem.

Thanks for the comments! I may cover the wires soon also.

[Biopyro]

Mmm loads nicely now.

Lovely cannon! I don't think the wires look bad at all either.

What kind of endcap is it? It looks as thought it should be female, but I see female threads on the chamber. Do you have a closeup pic ?

[Woody]

It's a flush male clean out cap.

I think it looks nicer off so I took the pvc holder off the propane. I'll get a picture of how it is now soon.

Just made 1" and 2" barrels for it. I'll probably be screwing around with it some tomarrow. Got some of these old marbles that'll fit very nicely in the 1" barrel so I might do some damage shots with them. If you have any ideas as far as ammo/what to hit for some cool damage shots let me know.
