[@aeroearth]

Excellent video! Few points from my experience doing anodising. Best machining alloy for subsequent anodising is 6061-T6. Some free machining alloys like 2011-T3 have more copper and give duller results. Make the anodes out of 6061-T6 al. alloy sheet. Better than lead. Clean the parts using aluminium cleaner from Caswell Plating. Do not let the parts ever dry out during the process. If you need to pause somewhere, hang part in bath of deionised water. Keep the acid bath under 23 deg. C. by submersing anodising bath in a chiller bath. Ice cubes in the chiller bath. The mark on your part is likely a residual acid mark. Try de anodised water in a spray bottle over kitchen sink. That way rinsed off cleaner or acid isn't sitting in the same rinse water bath as the part. Spray holes particularly well especially tapped holes. Heat the dye solution to 60 deg. C in microwave oven for best results. If colour is too dark or streaked due to acid leaching from hole or crevice, dip in a separate dilute sulphuric acid to instantly remove the dye, spray rinse very well and re dye in the dye bath. Spray rinse after dyeing to desired colour density then place in Caswell's mid temp. sealer bath at 80 deg. C for 20 mins to seal. Sealer is based on nickel acetate and part will come up glossy with deep rich colour. Spray rinse after sealing and dry with clean paper towel. Trust this helps.

[@fredcreer1929]

A cheaper solution would be to send it to a anodising company. Not as satisfying, but with all the equipment cost effective. I have difficulty justifying the price of my mill and tooling.

There are those here in the US that would like to turn it in to a nanny state as well but they haven't been very successful as of yet. Thank God.

Outstanding instructional vid! I've been combing KZbin looking for tutorials for anodizing and yours is MILES above everything else I've seen. I happen to be an industrial engineer and I can pretty quickly sort out the 'shade tree" DIYers (nothing wrong with them, usually, that's what DIY is usually about), but it's nice to see something from someone who clearly knows the correct terminologies and how to outline a process like this properly.

The fumes were dreadful and and no protective gear. lucky to be alive still.

[@pknaus666]

just a few tips from someone who works with stuff like this daily. 1.sorry for my, perhald, bad english in technical stuff. 2. use seperate tanks with deionized water to rinse your parts. at best you use up to 3 containers after the NaOH and 3 after anodizing. 3. in this little setup, some grams more or less put you out of the optimized range in anodizing or galvanizing! on bigger setups like i use to work is 1-2 gramm less or more like nothing xD 4. use more NaOH or or let it in for like a minute. i dont have much expirience in anodizing more in galvanizing. you did id awesome for someone who did it for yourself at home with nearly zero experience.

I worked my way through college as an electroplater and anodized tens of thousands of parts. That being said, there is nothing that will screw up a part faster than oil of any sort. We used an electrolytic process with a detergent bath to be absolutely sure that any oils were dissolved into the solution and away from the part being anodized. Something else that should be said - the wire that connects to the part will create a "shadow area" where the target part will not be anodized. I was pleased to see the author make the connection to his part in a way to avoid the shadow or to place the shadow in an area that doesn't matter.

Very Accurate representation of how Anodizing is done! I am an anodize technician and for the most part, you are spot on! Since most of the chemicals are variable depending on who you ask, the only kind of tip I could give you for future reference is that heating your dye will help immensely, then wash with cold water after that. Also if you want a thicker and more durable coating on your part, take the temperature of your anodizing tank down to around -1C Degrees. That will make it more wear and corrosion-resistant.

[@davidbeer]

[@Dr_Mauser]

When cleaning parts with a solvent like MEK (You can probably substitute MPK, which is slightly less horrible), you want to wipe it off from a surface before it evaporates and re-desposits the very stuff you were trying to remove. Where I work the procedure is to saturate a gauze pad, and wipe it on leaving a good amount of solvent on the part, and then immediately wipe off with another pad before it can evaporate. Then repeat the process until the dry pad comes off clean.

[@Hirudin]

I've done a little anodizing at home and I can almost guarantee that the slight blemish shown at the end was because the part wasn't dry (as you speculated). Personally, I dry the parts with compressed air (clean and dry compressed air) after rinsing. The unsealed anodize looks very cool as it transitions from saturated to dry. All the anodizing I've done was using sodium bisulfate, and I'd say I've had some nice success with it. Although I can apparently go buy sulfuric acid at the corner store, I didn't really want anything that corrosive in my house.

[@Mattwonga]

sodium bisulfate vs Sulfuric acid? what would be the improvement with the acid compared to sodium ?

[@Hirudin]

@@Mattwonga I wish I could answer more definitively, but I've only used sodium bisulfate so I don't know what advantages sulfuric acid has over it. I have to assume that sulfuric acid has some commercial advantage over sodium bisulfate though, since it's what is used by professionals. That commercial advantage could be anything from making it so anodizing jobs can be completed more quickly to it producing a higher quality (thicker? harder? easier to dye?) anodic layer.

[@Primer595]

I used to buy "Dry Charge" Batteries here in the U.S. .... They were batteries with no acid in them, and you went to the auto parts store, such as NAPA and bought the sulphuric acid. But I haven't seen that in about 15 years. Every battery already has the acid in it when you buy it.

Way to go,,, also for not loosing my attention. I'm a bit dyslexic and learn different than most people. I used to work at Allcan Aluminum where I worked on all the lines of extruded Aluminum. we used to anodize large crates of extruded aluminum but we never did any colouring of the metal. I've always wondered how it was done. On another note thanks for explaining all the details that included safety. Ive seen more idiots doing things could kill themselves than I care to admit. My garage is made of solid Sheets of corrugated steel. All Galvanized too. I have some open shelves as well and I had some muriatic acid (for prepping concrete) stored in its original container. The vapor released from summer to winter cause a lot of oxidization on the metal above the gallon jug even though the lid was tightly closed. It dissolved the cardboard seal in the lid. As you noted about double bottoms of the containers for storage. I think you may want be cautious about where it is stored as well as things around it. Why is it we try to learn from people that have no business teaching? Last Machine shop I worked at wanted to mix a special batch of acid to etch Nickel plated Valve Stems. The mixed up the acid and when it started to smoke they were coughing their guts out while I watched by the open door. Sulphuric and 3 other types of acid and I believe they didn't know the proper method, or which was the strongest or weakest. Thats Life I guess.

[@chrisdownunder5831]

One more safety caution. The gas given off in your caustic soda bath is hydrogen. The bubbles in the electrode bath are likely to be hydrogen and oxygen. There is a potential for exlosion if these gases accumulate in the workshop. Ventilation is very important.
