    Welding to or porting 12gauge barrel

    Ive got a bit of a project going on, has anyone done or heard of porting a barrel for a suppressor?

    And also welding to a barrel, Ive got access to mig, arc, tig, and brazing. which If any would be ok to use?

    Cheers

    p.s. please forgive how naive I am on the subject...at least Im asking before I do something potentially dangerous

    Was thinking of an underslung job so it doesnt mess with the line of sight. want to "fix" a collar about 2/3rds down, slide the suppressor on then make up a nut to tighten it onto a thread on the end of the barrel. port the section of the barrel where it runs through the tube....so the wallabys dont hear theyre mates getting vapourised

    I believe the wad keeps the shot safe from the porting holes. A dividing head and carbide cutter would do it - size and spacing I have no idea. I'd be cautious about welding, easy flow or something may be go. I reckon may be able to cut a fine thread at the muzzle

    Which reminds me Wallibies? What about a slight shrink fit, easyflow is brilliant just a cherry red, works like a "glue" runs like water,

    Red is hot enough(850c) to fuck easy flow but perfect for brazing.

    I am not going to recommend anything on the interweb but if your mods are towards the loud end not the loading end you should be pretty right.

    Yeah I might just do that, the thread will keep a bit of pressure on it anyway

    Clean it, flux it, tin both surfaces and flow together, you'll need good heat supply
