Hey everybody, check out my new combustion launcher. Here's the specs, tell me what you all think, and please rate this gun if you get a chance, thanks!

Name: ECL 1400 (Economy Combustion Launcher)
Setup: Over-Under Style
Chamber: 1'x3" PVC, 1427.72cc
Barrel: 31"x1.5" PVC
C:B Ratio: 1.4:1
Fuel: Metered Propane Injection
Meter: 6"x 3/8 Brass
Ignition: BBQ Ignitor
Ammunition: Standard russet potatoes cut in half, small apples, and paintballs in saran wrap for shotgun rounds
Modifications: Diametrically opposed spark gaps with dual ignition using a chamber short (burnt latke), Friction mounted chamber fan with on/off button and 9v battery pack, Custom built trigger frame with removable faceplate, hinging support block for breechloading, Quick interchangeable barrel ability, Exhaust end cap, onboard propane injection system including meter pipe and 0-60 p.s.i. pressure gauge, Krylon Fusion paint job, gun reloading stand (not pictured) made of 2x4 and padded with stapled-on towel cut to size.
Comments: This gun was built very sturdy, everything holds together really well. My goal was to build a combustion gun with ergonomics in mind, so i had to have onboard propane injection and breechloading for fast reloading times. It takes me about 45 seconds to reload at a comfortable pace. Probably about 30 if i was rushing. This thing shoots hard and it's LOUD! If i put in 55 p.s.i. into my metering pipe and dump it in the chamber it's like as loud as a 9mm Glock pistol. It shoots easily through 5/8" drywall every time, sorry no damage pics, maybe soon. I have yet to do a distance test but i'm guessing it's at least 300 yards, it gets about 10 seconds of hangtime when shot at a 45 degree angle on a 55 p.s.i shot. I love propane, it's so cheap, so powerful, so clean, and you use so little of it... hence "economy" in the name for this gun.

just a suggestion, I would stop with the red. I know, because when I was new, I used red, and everybody yelled at me. stick with the normal color. :wink:

oh, btw, nice gun

That's nice, it has to be for me to reply to it, seeing as I never hang out in the combustion stuff. Looks really good, who cares about the ball valve handles.

I like the handle alot. It is built and looks very nice. I too no longer make combustion because of the weak power but this one looks great.

hmm, If the mods dont want colors why don't they disable the option to do so.

No one cares about the red, man. It's awesome anyway.

Very nicely done. I especially like the hinged barrel for breech loading, never seen that before.

I do have just one question. How do you get the propane inside the chamber??? Maybe I'm just over looking that.

instead of double posting edit your posts.
and did you read the title...hmmm let me see "Keiths PROPANE INJECTED ECL 1400
he uses a 0-60psi gauge to figure how much hes putting in and ball valves and crap...just read the orginal post and it tells you.

I think taterhead was wondering how the propane actually gets into the chamber from the meter pipe... if so at the end of the second ball valve i just put a 90 degree street elbow tapped directly into the pipe, sorry it may be difficult to see from the pictures. Look at pic 1, it shows the best angle of the street elbow from the ball valve into the chamber
