I just built my first pneumatic cannon out of ABS and realized i used a heavy duty PVC solvent. Should i scrap the whole thing or trust it will hold?

Note, i have tried it out a few times. i took it to 85 psi. no leaks. seems to be ok. But from a safety standpoint?

thanks

Oohh. I don't know about that one. Does't look like there's too many people on right now so you might want to PM someone like BC pneumatics and he could answer that for you. I dont have any experience with ABS but I would think it may not hold too well. Don't hold me to that though.

well, abs is not good for pneumatics in the first place.

with the wrong solvent, I wouldn't trust it.

Scrap it for the two reasons:

1:You use ABS on a pneumaitc
2:You used the wrong glue.

Never Use ABS on a pneumatic.Combustions are fine.

unless its pressure rated

ABS isn't pressure rated by definition

Actually, there are rare ABS variants that are pressure rated, but
1) they're expensive
2) very hard to find

He Lives!


Anywho even if it is rated he still used PVC cement for it.

I sense a heated ABS vs PVC argument approaching...

indeed....

I hope I dont get involved tho

Well, I'll start it off.
PVC has the advantage of being presure rated, and fairly strong.
ABS is more shock resistant, and can be safely used in combustions. I would use it in a lower pressure pneumatic (below 90 psi) because should it rupture, it will only rip down the side, not shatter like PVC.

No, there is no argument. A-98 is wrong, end of story, no need to argue.

And- the cannon is worthless as is. Scrap it.

Lol, that sounds like my first pneumatic.
It help up to 90 pis with no fail, until my ghetto schrader blew out:(
