Is it safe to tape a 1/2 inch BSP in the side of a 1'' galvanized steel pipe with 3.8mm wall thickness. Its so my chamber(600psi) will be closer to the barrel for a more slim shape.

It would only be holding on with about 2 threads, just the threading alone wouldn't be very safe IMO. Welding this would be ideal.

dam, whats it call when you cut a pipe to mach the curve of a nother pipe.
I remember having a web site in my favorites that gives you a template you can print out and would fit perfectly

im no pro welder but ill give it a shot then fill the cracks with epoxy

edit: No point of doing that might as well use a tee on 90* fitting :lol:

I can't think of the name myself, it looks like this
this if you do have a grinder and welder and appropriate filler, then give it a shot.

Beautiful weld. did you do that?

By the way... i seem to remember something about "saddle cut" i could be wrong though.

If you can't weld, have it done for you. I don't have the tools to thread 2.5 inch pipe. I took it to a shop and had it done.

It's called 'Fish Mouth"

You could drill / tap then tig weld the fitting in place. No Fish Mouth required.

Yeah, its beautiful mate *kiwi accent*:lol:.
I'm sure it was done with a TIG welder, my welds don't look quite that good.:roll:

P.s expect to see a fair bit of welding in my upcoming cannon.
