Would dry ice/isopropyl 97% alcohol work? And would pvc hold the coolant during the "bath"?

They are both steel 304 tubing, they are not actual barrels. Do you think that burning them is viable? They are both 1/4" OD

I just got the 0.177 and 0.22 barrels. Whit the first barrel I made a very silly mistake and probably I don't have the possibility to repair it (I tried to test it with a pellet but it got stuck and I tried to push it out with a wood spike but it got stuck too. Any ideas on how to repair it? (air pr...

Yes, I believe that the second one is better but I am clueless about how to make either, so any idea on how to make the very bolt? I mean a bolt about 0.18" or 0.23" diameter with an even smaller pin that pushes the pellet further does not sound easy to make, just saying :/ But the coolest part of t...

If I post a paint picture of my desing and then an actual picture of the "rifle" so far, would you mind checking it? It is still lacking the stock...

Ahmm I am not sure, most people I know prefer amazon...

Thanks, I just found in this website someone saying that I could find them in macmaster, I'll probably buy it from there, sadly it will take about 20 days shipping. Do you think that 0.025" or 0.003" will really make the difference between the barrel ID and the pellet diameter?

I have problems trying to find a barrel I´ve made a full semi automatic system with DCV and QEV, I have the tank and necesary regulators, my only problem is the barrel. As this is my second gun, I wanted to make it great, so I don't want to be making its own ammo, I rather use common ammo, there is ...
