Thread: 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

What are you putting on the barrel?

Suppressor

Draw me a picture

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

Might add ill be running the softest loads I can find

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

Don't disount locktite just yet either

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

Yea let me know when ya ready to go Im good most weekends. Im pretty sure Ive got some easyflow here, just not sure about getting the barrel cherry red

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.

Can you just sweat it with some solder?

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
