I don't remember talking about the threads at all but I am interested in that. The soda bottle threads are different than NPT. What the hell is goin on there?

Well i'll explaine,i already did this in a previous post im sure of it...Well any ways what i do is take off the bottle lid and take a wood rasp to it and rasp it back till it just about fits inside the 3/4brass nipple then i use alot and i mean alot of teflon tape and wrap the hell out of the bottle and thread it into the brass nipple and i gte a pair of vice grips and tighten around the neck lip of the bottle you no the bit where the lid stops at and tighetn it up like that.

And no i do not use epoxy in any way at all this is just my way of doing it and it has worked for me for about 3 years and i have only every had one bottle pop off the end which was loud but it was low energy due to its ligth weight.I have also yet to shoot the nail polish i might do that tomorow maybe and post a pic of the nice spalt :P .
