View Full Version : My parkerizing setup

My parkerizing setup:

I started out with 1 tank I bought on ebay for $90 but I needed another for the pre treatment Shooters solutions sells.

I found a stainless steel cabinet that hospitals use to keep food warm and cut up the doors to make the tank.

I donít have a sheet metal brake so I bolted the sheet metal between 2 pieces of bar stock and bent them over with a hammer.

I used my father in laws mig welder with gas to weld up the 2 homemade tanks I made, the first time I ever used a mig welder.

The welds looked terrible and the tanks leaked badly. I tried to use gas with some stainless steel filler rod which didnít work muck better.

Now the Parkerizing tanks are only for liquid that gets to 190 F so I figured I would try some JB weld on the outside corners which worked perfectly.

I would not subject the JB weld to direct flame but other than that they are still working.

The Pipe burners:

The pipe burners that Brownells sells are fairly expensive and really from the pictures look pretty simple.

The burners are just 1Ē iron pipe that I brazed shut on 1 end. ( didnít want to buy caps)
I drilled pairs of holes in a V down the pipe where it sits under the tank maybe a #18 drill for these.

The other end is a 3Ē to 1Ē reducer with a cap. The cap has holes drilled in it so air can mix with the propane. (They are not adjustable)

In the middle of the cap I drilled a 3/8Ē hole for the propane. The piece of 3/8 pipe was plugged and brazed then drilled using a small drill like a #50 or something like that.

The rest of the setup is just various pieces of pipe joined together with pipe dope for use on gas.

I use propane for fuel and I read somewhere that a gas grill regulator did not flow enough, so I used a regulator from a turkey fryer which I bought to smelt lead for bullets.

To maximize the use of heat from the burners I put the pipes fairly close to the bottom of the stainless tanks.

I also use some scrap to cover the burners from the sides so the draft does not blow it out.

I can get the setup up to temp in about 15 minutes.

Once I get done using the pre-park solution I turn off that burner which is why the valve is there.

I know this setup looks pretty crapped but it is functional which was all I cared about when I built it

I modified a tank I found at the scrap yard I was gonna JB weld it too, don't know what type of SS it is but it's hard, anyway I silver soldered it, I re-parked my M1 carbine about 5 years ago and I haven't used the tank since :D , everything I've done since then I can fit into a 4 quart pot on a hot plate. Thanks for the burner info I'll keep that in mind.
