I guess the next thing I need is MAPP gas to heat treat the receivers. Do I need the two can type that includes the oxygen or will the one can setup be enough? The only thing I can see using it for is the receivers and starting the coals on the BBQ.

I use a simple propane torch like the one you solder plumbing with and with the metal being so thin, it has no problem getting hot enough.

I think MAPP will be fine,, others ring in if I am wrong.. you could easy get too hot with an oxy kit.
just a note do not stock up an gas!! two cylinders is all you should have in your house at a time, empties count as full ones too. if you have a fire it will make it much worse, and your insurance company can say a precentage if the loss is due to the quantity of gas accelerating the fire. if they feel the fire would only be half as bad without the gas they may only pay half. oh yes ONE gas grill tank is WAY too big to store in the basement or even garage. just some unrelated info.

Thanks for the advise hotbarrel. I only plan on getting what comes in the package. I have an outside storage room that I keep this kind of stuff in. Also I do not use a gas grill. I am old fashoned when it comes to cooking meat. To cook meat properly it must be done over a wood/charcoal fire. I was thinking about using the torch to start the charcoal.

unless you're cutting or brazing, you won't need the oxy. I believe you can even braze with the MAPP if i'm not mistaken

Yes MAPP is plenty hot enough but it's nice to have the oxy set up for other stuff. When I bought mine the price difference wasn't that much so I went ahead and got both.
Hotbarrel thanks for the info on insurance companies and fire. What is the recommended way to store the cylinders? I don't have an out building as I live in a house with a very small yard. What about a small metal cabinet?

 

[Painthappy]

Are you guys heat treating the entire receiver? Or just the X - Y Axis on the rivet holes...?

Just curious.

That's what I did as well.

Hopefully it wont be a consideration after 9/13, But if you want to be able to silver solder a muzzle device, or remove one that has been silver soldered, you will need the Mapp/Oxy set up.

 

[fal_shooter]

I only plan on XY and rails but as usual 7.62x39 brought up a good point on the silver soldier. I guess I will get the Oxy. Can I use just the gas w/o using the Oxy or do I always need to use both?

 

[mbadboyz]

Quick question....When heat treating the rails, are they done before or after they are spot welded on to the receiver?

 

[fal_shooter]

I'm not sure of the correct method but I plan on putting them in and fitting them then heat treating them after I have filed them down to fit. I have seen some post where they said you shoud heat threat them them install them but that doesn't sound right to me. If anyone knows for sure I would also like to know the best way to do it.

the only way to cook . I took the lava rock out and threw away the burner to make room for the mesquit chunks..

As for gas storage,, state laws may vary HOWEVER N.A.F.P. 54 is the national recognized standard. My copy is at work so I will not quote much , BUT I do know three cylinders is TOO MUCH in a home. easy answer is to buy two and when one dies get the empty out of the house and replace it, you need never run out compleatly.
as for your gas grill cylinder leave it attached to the grill, if you want to have a spare chain it to a tree out of the house. or just leave it out next to a shed.. I am not shure enough to quote but I think putting it in a shed is a bad idea too. I put a small plastic bucket over the valve to keep rain off of it.

Ok I don't have a gas grill. I was talking about using the mapp torch to start the wood charcoal on my BBQ. I usually use one of those stove pipe charcoal starters and I think using a blow torch should get the charcoal going real well. Grill gas is for wimps.
