Parkerizing Setup?

[massguy]

Looking to go with the Shooter Solutions kit and need some help on what to use for a budget double boiler setup.

Thinking about using a large stainless pan on top of a small propane grill with a couple of smaller suspended pans (preheat and park) heated by the hot water.

Any suggestions on what SS pans to go with or an alternative budget setup?
I don't plan on using it often and it will be mainly for small parts up to about 11" long.

Also need to figure out how to suspend loose parts and akm receivers.
Thanks

I used a stainless pan about 24" long from a restaurant supply store.

I oven pre-heat my parts but found little difference between pre-heated and cold except on the tank temp.

For small parts like you are going to be doing, this will work inexpensively:

If you shop around I am sure you can find something cheaper than $14.00.

Parkerizing Setup?

Years ago I used to refurbish surplus magazines. After we pounded out the dents we degreased and sand blasted the steel.

We used a stainless steel cooking pan on a propane stove outdoors. We didn't buy a parkeriziing solution, we made our own. There are many formulas out there. The main ingredient is phosphoric acid. There are additional ingredients you can add to slightly change the colors.

Once the metal was pulled from the boiling solution, it was extremely suseptable <sp?> to corrosion. The hot metal dried instantly. The next step was to immediately immerse the metal into oil, we actually used old drain oil, think of it as recycling.

The color you get has a lot to do with the base metal. If you had welds, they would often come up as a different color. I've seen pitch black come up, I've also seen what looked like olive drab green.

Remember, parkerizing or phosphating is actually a rusting or corrosion process where the coating simply holds the oil, which protects the metal.

I've parkerized +25 AKs using my stove top to heat the solution in a stock pot and then, we dumped the heated solution into a flower vase full of barreled actions or small parts. There is no need for a double boiler or even to suspend parts. Just toss them in your tank while it's on a burner and flip the parts over after 10 minutes or so. After my first build party, we got a tank and burner and that's how we did it. Conservatively speaking, I'm going to guess that over 2,000 homebuilt AKs have been done this way in the last few years in California. Between 500 and 750 were done that way at my home.

BE CAREFUL. I was careless and lost a gun. My new setup has a better thermometer and a double propane burner, the results are good now. People always say how easy it is BUT IT IS NOT!! You have to sandblast, prime, and keep it in as short a time as possible. None of this half hour BS, if it doesn't take in 5 minutes you need to get worried. USE DISTILLED water.

Anyone have a good kit they recommend. I'm going to be doing about 6 aks and a couple other guns pretty soon here.

from viewing your thread I think you had mutiple problems going. I'm not trying to throw you under the bus just pointing out things I've seen ion my experience.

You never said what brand solution you used.
I tried to DYI a solution and could not get the acid level correct. Parking uses very little Phosphoric acid. Like nearly none at all. the Jasco and Home depot metal prep is enough to make a few hundred gallons of solution.

FYI Brownell's recommends distiled or de mineralized water but also list right in their instructions that the use of tap water so long as it is not to hard will also work.

I can tell by the reaction you had in the pan that the concentration of acid was incorrect. but again not here to pick that apart.

My recommendations are

1) Get a good stainless pan for what ever size you need to do the job.
2) Use a trusted solution. No home brewed stuff unless you are a chemist.
3) Use distilled water it's a buck a gallon at wally world
4) An even, easy to control heat source.
5) plastic utensils to handle your parts.

Now that said time IS NOT a factor. Proper solution mix will stop reacting when the steel is fully converted and parkerized.
I've walked away with parts in the bath for a hour with no ill effect.
and I don't run my bath at 190˚F. I run mine at 170˚F Acid reacts slower and less aggressively at lower temps.

As for solutions I recommend
Lauer custom weaponry solution but since they doubled the price of a gallon of solution. I now use Allegheny Arsenal parkerizing solution. as one gallon make 28 gallons of solution. So $69 for a gallon that will make near six complete baths.
Brownell's also makes solution in zinc or manganese and they have pre blacking dip.

I used this ebay stuff and I really did not like it. I probably ended up using hard water too, and did not sandblast first.

Yeah that stuff don't look very good. the color of the concentrate is wrong.

Go to a restaurant supply store or online and buy a stainless steel bread pan and a cooking thermometer. Go to walmart and buy one or two single coil electric hotplates. Go online and order some parkerizing solution. Do some reading online about parkerizing. I was able to get everything for about a hundred bucks and it worked perfectly.

Ok you got me thinking about using the Walmart double electric hotplate and a 1/3 size SS Steam Pan for the park solution which has the dimensions Im looking for.

I can get a cheap pot to fill with distiller water for the preheat.
What oil can I use? Do you need to submerse it in a container of oil or can I just spray with some gun oil or CLP breakfree?

Not sure what is a good thermometer to use - any links to suggested ones?

I sprayed WD-40 on my parts after removing them from the solution. I used a dial faced cooking thermometer like the kind you would stick into a turkey while cooking it. You can fashion a holder for the thermometer from some wire so that it sits on the edged of the pan. 195 degrees give or take a few will work. What's most important is that the metal is CLEAN.

What he said

and I'll add a good rust preventing penetrating oil. and I spray it on and let it soak for a couple hours. then tell the customer to oil it daily for a week. any gun oil, hydraulic oil, compressor oil, turbine oil, spindle oil, will do. Petroleum based oil. I use the turkey style thermometer. works great, stainless steel, just don't leave it in the bath.

The post park oil can be almost anything.

Take a look at simple 10-30 or 10-40 motor oil.

No need to spend money on the oil bath with high end CLP

You just want the pores to completely fill with a thick oil.

WD40 is Water Displacing- the 40th formula.

It is a light oil and will not stick as well as simple 30 weight automotive oil from the auto store.
