Harlock..
i already did do it myself. (what else did you think... ) I made it silver. it is not hard anodizing.
Anodizing can be dangerous, it must be done outside doors, precaution needs to be taken, under adult supervision, wear protective glasses and old clothes, have an emergency room standing by, predial 911 on your phone.. In other words; know what your doing, or don't do it.
Needed for anodizing;
-plastic tub, that can take some heat (never use a metal one to do the anodizing)
-lead plate
-dc power supply, 12 volts
-H2SO4 (battery acid, as used in car lead batteries)
-NaHCO3 (natriumbicarbonate, baking soda) (for sealing, not needed if you add a color)
-demineralized water
-a pan to do the shielding of the anodized part
-protective clothes
to anodize, you need the plastic tub filled with a 10-20 percent H2SO4 (anything within this range is okay) the remaining 80-90 percent is demineralized water.
The water will get hot from mixing the H2SO4 with the water, and from putting energy in it with the power supply.
the aluminum (to be anodized) is clean, and sanded with 400-600 grid sandpaper. (haven't tried polished aluminum yet) the aluminum part needs to be setup as the anode (+ pole) and the bath ,the lead plate, needs to be the cathode (- pole). rule of thumb is that you need 10000A per minute per square meter (10.76 square ft) (keep in mind; holes etc increase the surface)
No copper or other materials than the lead and aluminum may touch the accid bath. (use an aluminum rod to connect the anode to the aluminum part, make sure there is a good connection between both.)
After anodizing you can add a color to the aluminum or leave it silver.
for leaving it silver,
(this sealing procedure is needed)
cook it in demineralized water with a 10g NaHCO3 per 1 liter. cook it for 30 minutes.
if you want to add a color;
pick up any normal cloth dye colors.
place it in COLD (demineralized) water with the color added, if you put it in boiling water, the sealing will start before the color is on, which can make some weird spots.
The ability of anodizing aluminum based on used material;
-1000 Good
-2000 Poor
-3000 Good, nice yellow/brown color
-5000 Excellent
-6000 Excellent
-7000 Poor/Bad
