Parkerizing tank help

[bakemono]

I just successfully fired an HK91 build so its finally time to make it pretty and protected. The only problem is that on an HK, the barrel is pressed and pinned into the trunion, which is in turn welded to the receiver, making the sucker about 28" long. Anyone know of or have something I can use to parkerize this thing? If all else fails, I'm going to have to make a tank out of stainless sheet and have my cousin do the stainless welding ( not sure my welding would hold water).

Other question: would it be possible to parkerize half of the piece and then flip it aroudn and parkerize the other half? Or would I get too much flash rust on the unsubmerged, freshly sandblasted part of the piece while holding it over the park tank?

I saw a 1919 done that way since it wouldn't totally fit in the tank. It turned out fine. You couldn't tell the difference.

You can get a real well made 40" tank for $120 here, probably cheaper and quicker than making it yourself :

Mine arrived in about a week. I added a ball valve with a drain hose on the end to make draining and filtering easier/safer.

Where are you located? I would have to measure mine but I think it is 36" long. I would let you use mine for say the price of the gas.

I'm in redondo beach, about 200 miles south of you. I don't think I can afford the gas, haha. I really do appreciate the offer though. I'm going to check on some stainless sheet prices when I get off work. If I find nothing, I might go the holescreek route, unless I can find someone willing to let me borrow theirs.
Holescreek: thanks for the link, and thanks for all the help. Your writeups were instrumental in getting this build up and going in one shot with very little trouble shooting needed.

If you still want to make a tank PM me for details on a cheap solution.

Submersible electric element and PVC pipe.

Before having a stainless bin welded up try going to a restaurant supply
first. You may very well find a long enough stainless bin to do the job.

Other than that you might consider a dry-on Duracoat paint. They go
up to 600 degrees for the non-bake on paints. Downside is you have
to prep it and then, after painting, wait two weeks for it to dry to
full strength. Great thing though is they have a lot of colors.

I did the half-now-half-later park on my 1919, worked well, but it does leave a line - my barrel shroud covers it so no big deal.

I have a few large sheets of stainless steel, & I've been thinking the same thing - make a park tank out of it. If you have someone who can do the bending/welding I'll give you the ss in return for making me one too. I'm in San Diego.

I plan on duracoating it right after I parkerize the sucker. I don't have an oven large enough to get the bake on stuff, but the catalyzed version might work out for me.

Crap! i just saw this. I just grabbed some stainless, buuuut it wouldn't hurt to take you up on your offer. A 2nd one would be good for the rinse tank. My cousin welds up stainless all day, and is in Costa Mesa. I'll ask him if he's up to doing a second/third tank. What size stainless do you have?

[ChuckD]

I have a 4X6 sheet & 4 or 5 strips that are 3' to 4' long & 12" to 16" wide.

In a kind of/sort of related question . . . I was thinking of using JB weld to "weld" the pieces together - anybody know for sure if thats a good idea or not? I know JB weld will stick to stainless, but I do not know how it will react with the parkerizing solution.

[Aznatama]

I would not use jb weld. Either actually weld it, our bolt it together using silicone to seal the joints. In pretty sure silicone is resistant to acid

Silicone is most definately chemically resistant and works perfectly well.
