Congratulations, you've built yourself an advanced spudder. I can't really get a good look at it from the video, but it looks like you put some thought into the meter. However, its unique configuration also causes hoses and ball valves to be in your way at the rear. Maybe install a brass elbow on the meter inlet so the hose doesn't have to take such a radical turn.
It looked like your are holding the propane tank on with packing tape..
..get yourself some big hose clamps...will look a whole lot better.
Also I noticed you didn't close the meter valve after you dumped the fuel in the chamber. You should go ahead and close that to keep the pressure spike off your pressure gage.
Do something else with your ignitor...mount it in some way. Maybe be a good opportunity to build yourself a handle and trigger of some sort on it.

Great job! Is that your first spudgun? If so, I give you props for building an advanced combustion as a first instead of a simple pneumatic or a spray n' pray.

thanks for the comments and to respond to your concerns.
1) for the hose, i changed it today, i put a 90 after the T so that the hose runs about 4 inches from propane tank to ball valve.
2) Packing Tape!!!! NEVER. lol, actually it is hockey (which is the best tape imo) and yes it has to change. I used it for mock up and am using clamps.
3) I watched the video and yes, i should have closed the valve, thanks for the tip
4) i am still in the air with the ignitor, not sure where to put it, but i want to mount it to my case later.
Again thanks a lot and i hope to improve it more and more

flinger, actually, that was once a spray n pray. After i found this site i decided to do the swap ( i also broke my jaw a few weeks ago so i have way too much free time, (missing my track and lacrosse season due to that)) For the swap i put a meter on. results were inconsistant. I put a fan in soon after and got consistant results. Lastly i put a 6 foot barrel on 
and started blowing holes in 5/8 ply. Very happy with how it has turn out

You should include a look at your damage in the video. Keep us posted on the improvments.

ask you shall recieve star man.
front side of ply
back side of ply
nice little grouping i have here, three shots all close together, top left is an exit and the two on the right are entry holes
This here is what i like to call the, "worst case box". If the unthinkable happens, i have 3/4 ply between me and whatever is coming. It is far better then nothing especially when anything can happen. It only has 3 sides so that if anything does happen, any objects(or infact the whole gun) could eject away from my body.
my ignition placement, hope you like it star man. Has good placement for use with thumb when holding the handle
Updated fuel line. I put a 90 in there to cut down the length of the line and make it less awkward to handle
Here we can see my chamber fan switch, battery just above, chamber fan and pressure gauge. It is hard to make out, put a piece of wood at the bottom is holding the gun in the holder.
And a picture of the whole gun. I plan on painting it a nice black to get everything the same color.
A note of the worse case box. Inside of it i placed several pieces of wood that tie into the chamber fittings. Those are what take the force of the shot. I also put some foam in it to prevent rattling purely for my distaste of extra noise.
Thats it for now. Let me know

Oh dude, I'm sorry I'm just catching your "upgrades"... 
Gee, a worst case-Great Stuff foamed out-shoeshine box-frankenspudder? You have somehow managed to convert a reasonably respectable advanced combustion into a ....well....words escape me at the moment....
Criminy man, what in the devil possessed you to construct such a thing?
I am however, laughing... Where's Gort?
Edit: The damage is impressive BTW...

Offtopic:
How exactly did you break your jaw might i ask?
I broke my way back in 6th grade. I fell out of a tree. Im just curious, because there really arent too many ways one can break a jaw bone.

i like the "last case box" 8) , i've been thinking of a military surplus flak jacket (bullet proof IIIA jackets are $300), both still leave your arms and side of head vulnerable.
i use propane, has a nice kick, if i were to go to MAPP, i'd definitely reinforce the CC. my first spud gun has 5 interchangable barrels (1", 1-1/2" and 2" dias) the weak point in my gun is the barrel/CC union/joint. i always wear gun muffs and safety glasses.
