oh now that is cool...wish I still had access to an awesome welder but...tapping the buffer tube might be....kinda fun.

[Ivars]

Is that the " she just wouldn't listen now the guberment ain't letting me have no gun" lower?

Kinda on the same lines as "make shift prison cutlery" if ya get my drift.

Interesting. Quite figuratively Legos for grown ups...

I've got a welder in my father's garage... hmmm

[shooter]

 I do a lot of welding and machine work, and threading for the tube is gonna be a *****,

I could just imagine if I did it.  The buttstock would be at a 45 degree angle from the rest of the gun.

Sounds like it takes a 1 3/16 - 16 tap.  Brownells has them.  I bet you could weld the buffer tube in place, too. 

Edit:  nevermind, the buffer tube is aluminum.

[RobertH]

screw welding.... duck tape is there its at.  i'd rather finish an 80% lower.

[bkoenig]

Actually, thinking through this some more....why not just buy a mild steel tube of the correct diameter and weld it in place for a buffer tube?  Add an endcap with a threaded hole and it would work with an A2 or A1 stock.

To me this sounds like a nightmare. Trying to keep all the components lined up and clamped in place and not distorting during welding? Sounds like a wet dream.... This thing is like a 3D printer gun sure you can do it but not practical...

[gsd]

T, pin and clamp it, then button weld, just like you would on a car when replacing a body panel. low heat, no warp:)

[tstuart34]

Only if I had a TIG would I attempt. MIG gets to ugly and keeping that low heat without filling up your holes is always a problem. I have seen people screw up a lot of perfectly good stuff with clamps and "low" heat welds

That's what I was thinking.

Would oxyacetylene work for this?  I haven't done that kind of welding in years but I seem to remember it being pretty good for lighter gauge steel.

[tstuart34]

I've never oxy welded... but it does work for light gauge metals. But you still induce a lot of heat into the metal. It is like sweating pipes you want to get the parts you are welding hot enough to keep the filler following into the void. You are not actually melting any of the prices together the filler is like a glue.

 With tig welding to some extent you can actually weld pieces together without adding any filler because you can cause the base material to get hot enough to flow. Becuase of this you can actually push the filler into the metal and cause a fusion of sorts. This all can happen very quickly very precisely and done PROPERLY cause very little distortion.

Only one thing you need.

Hey Fly...Kilo-Lima 3?

Hey Fly...Kilo-Lima 3?

Hmmm...I will have to check with R&D.
