Perhaps I should have placed a qualifier in my opening request for only those who have actually tried it to comment, all others need not reply.
so i guess even if someone has just an opinion from other sources they shouldn't post that opinion?

i have been around business's in the past that had parts anodized and even spoke up once about doing such things in-house rather than sending the parts out. cost of the equipment and the danger of the chemicals involved were usually the reasons why they didn't.

i'll refrain from bothering you with anymore suggestions in the future. wasn't awar only a select few were allowed to have an opinion or suggestion. sorry to have bothered you sir.

In regards to safety and the required items needed to anodize. They are common and easy to get items.

Sodium Bisulfate: (pool additive like Aqua Chem pH down) no doubt used by some not so bright folks every day in their pools

Sodium Hydroxide: (drain cleaner or lye), available at all hardware stores and used by not so smart people every day to clear clogged drains.

RIT dye: used by some of the dumbest people on earth. I have used it many many times

Battery or source of DC current: I use these daily.

Aluminum: Seems pretty stable

Room temp Distilled water: Can do

boiling water: My love for hard boiled eggs has rendered me a master that this.

Soap: I got that down to a science

Rubbermaid tote: Expert status already.

The small amounts of hydrogen that escape during the anodizing are noted and not of grave concern.

I already own safety glasses and rubber gloves and several windows that I can open.

Back to my original question. If you have experience at DIY anodozing I would love to here your tips and tricks.

When your heating water for a chemical process dont use the boil by look method. Boiling is different at different elevations and if your too high up certain temps cant be reached just boiling water. I know this from cooking and fumbling with candy making.

If your looking to diy anodizing i wish ya luck. Its one of those things that can be disastrous and actually make a part porous if done wrong even with the right setup. Your going to need to need to test for porosity on test material before doing recievers or other gun parts with scrap from the same grade aluminum your anodizing.

When i did machinist type work many moons ago my best friend and i would run parts to a local anodizer and one thing he always wanted was test scrap so he could test his mix and tune accordingly.

Thanks, as a fellow candy maker and maple syrup boiler and veggie canner, I learned a while back that at 1,100 feet above sea level (where I live) water does not boil at 212F. I wonder if I could couple syrup making with the anodizing (to save time)

P.S. I make some awsome maple candy. Soft ball and poured over snow is a family favorite.

Thanks! even if I fail misserably I will be miles ahead of anybody that fears trying in the first place. I am an expert at failing. I can do it almost without fail. I dont need help failing. I can handle that on my own. Just like I dont need assistance in discouraging me from trying.

Not trying to discourage you just pointing out the realities

Ive got two m1 carbine recievers one in a complete gun the other is 80% complete minus bolt stock trigger. Im debating whether i want to invest in building a bead blaster and compressor setup and diy the parkerizing or send off the parts to be done.

Im not going to be doing a bunch of em but i do want the tools to build a carbine. Both need new barrels neither are timed correctly nor headspaced properly. Both barrels are canted.

I have not seen one mention yet about disposing of said chemicals. It's not like you can pour crap like that down the drain, no matter if it's yours, or the towns'. And proper removal is NOT cheap. Axxe, that is one reason you forgot why some companies don't do it. Disposal of waste.

OP, if you want ONLY suggestions on how to do things that are best left to the professionals, you're going to have a lot of one-post threads, because most of us have come to the conclusion that it's not worth our time to entertain. Just sayin'.

I will list them again

Sodium Bisulfate: (pool additive like Aqua Chem pH down) no doubt used by some not so bright folks every day in their pools. sodium bisulfite is sold by some home winemaking suppliers for the same purpose. In fruit canning, sodium bisulfite is used to prevent browning (caused by oxidation) and to kill microbes.

In the case of wine making, sodium bisulfite releases sulfur dioxide gas when added to water or products containing water. The sulfur dioxide kills yeasts, fungi, and bacteria in the grape juice before fermentation. When the sulfur dioxide levels have subsided (about 24 hours), fresh yeast is added for fermentation.

Sodium bisulfite is also added to leafy green vegetables in salad bars and elsewhere, to preserve apparent freshness, under names like LeafGreen. The concentration is sometimes high enough to cause severe allergic reactions.[

That being said, I think (if one can eat it) that it CAN BE flushed. I would already be diluting it with water anyay.

Sodium Hydroxide: (drain cleaner or lye), available at all hardware stores and used by not so smart people every day to clear clogged drains and as such (and by its very nature) is meant to go down a drain.

RIT dye: used by some of the dumbest people on earth. I have used it many many times and alway dispose of .......... Yup you guessed it. Right down the drain

Battery or source of DC current: I use these daily. I will refrain from flushing this as it reusable (and because it would no doubt clogg the drain requiring more drain cleaner (the horror)

Aluminum: Seems pretty stable and is the part I hope to anodize so nope, I wont be flushing it.

Room temp Distilled water: I flush that stuff all the time. I think im good with that one

boiling water: See above. Boiling water down the drain frees up grease clogs too

Soap: Need I say more?

Rubbermaid tote: reusable

The above list may be why there has been no mention of disposing of the items needed.

LOL at "left to the professionals" How does one become a professional??? By doing and disregarding those that dispence discouraging words that would keep one from becoming a professional.

Back to my original question. If you have experience at DIY anodozing I would love to here your tips and tricks. If however you only have discouraging words, there are a host of threads seeking your input.

Whatever, man. So long as you don't live in my town, pour it down the drain, knock yourself out.
