straight flatline barrel WORKS!!!

I don't think it's gonna break the balls,  I've done  meaner stuff to the inside of a barrel then that. 

I just think it'll have to MUCH spin  and it'll send it straight up.

wtf did you just say? seriously...

maybe i dont have 100 bucks to spend on a flatline. a 50 cent role of electrical or masking is so much cheaper. if you dont like the idea, too bad.

the only way I see it working is to design a barrel from scratch with a flat bottom. The reason for the flat bottom is so you can put needle bearings in it...keeping the flat side as narrow as possible is the key....the top rounded section would have a graphite finish to it to create the backspin.  It may or may not work

Good luck. I hope you succeed.

So you tried this tape thing XX?

I don't see how this could work well. Getting tape inside a barrel to be perfectly straight with no bumps or wrinkles seems impossible. The only way I can think of is to use a thin dowel rod and stretch the tape tight and secure it to the rod at the ends, put it in the barrel and hope it sticks and doesnt wrinkle and then cut the ends of the tape that hangs out off. Good luck, you have more patience than I. This doesnt sound as bad as the guy who suggested putting jb weld at the end of the barrel so the paintball would "ramp up".

go for it maybe these guys did it wrong.

its not that i dont like the idea, its the fact that even if the tape doesnt break it, the tape would SERIOUSLY slow down the ball and this isnt very likly but its possible for the ball to get stuck in the barrel, and like i said before u couldnt squeegy the barrel, the tape would come out, like i said its not that i dont like the idea, i just dont see how it could work

i am god. quite simply. i got my j&j in today, and immediately tested this idea out. here are the results.

Materials:
-14 in. Tippmann Werks barrel.
-Packaging tape, the kind with the reinforcing threads woven in, to be specific. about 4 in.X 1/2 in. used various sizes, this one had the most consistant results.
-Triad paintballs. size not sure. (cheapo paintballs)

Procedure:
-apply tape to inside top of barrel, in the front (buisness end). make sure its smooth.
-that's it. simple and CHEAP.

Results:
-SUCCESS!!! there were flaws though. paint actually survived for the most part, but if the edges popped up on the tape, it would catch the ball and pop it. rare though. another downside was sometimes it would shoot any which way, but in part a blame the paint. overall, i did notice a distance increase over the j&j that i compared it to (also 14 in.) I R00L!!!

Are you shooting the correct fps?

Please post some more 'scientific' results- ranges, groupings, etc. It's easier to see the effectiveness if we've got two sets of figures to compare.
