Sealing air tube venting hole

[Seeker]

Hi,

I need to make a bigger shooting chamber. In order to do it I need to move the regulator venting hole more far back. What would you suggest to fill the original venting hole with? It is below 1mm in diameter. Welding or soldering maybe?

Thanks.

Welding would be the only viable method. Even then, I'd consider it pretty sketchy.

You can make a standoff spacer for your regulator, and cut an oring groove in it's outside diameter on both sides of the vent hole to effectively seal off the hole from the air pressure.

If I'm understanding what you are trying to do.

Right, I was thinking about orings as well. Do you think it is the best approach?

It's likely the safest for sure. Worst case is a high pressure leak from the hole if the orings fail, which shouldn't be any different than a regulator leak.

If you need to make a standoff for the regulator anyway, you could kick both problems in the butt with one part.
