Anodize Small Aluminum Parts at Home

[Peter]

I often find myself making a bracket or hook or mount or something-or-other out of aluminum bar or angle stock. It is easy to cut and shape and it stands up to a salty environment. But up until now I had no idea how easy it would be to anodize the finished part in my basement.

Check out this video…

In the second video he shows writing on a yellow anodized part with sharpies and sealing that writing in. This opens possibilities as well since you could put important notes/ warnings/ or markers on parts if you wanted to.

Brewster- show or send this to your Dad. Another use for baking soda. Co-op with the other component part manufacturers and put together/sel an anodizing kit for nuts like us. Walter

Public can play with some Sulfuric Acid but once you start with batches and become Commercial, EPA will setup camp with you.
Hazardous waste, shipping and containment will be words heard often.

I remember when you could buy the acid in an autoparts store. Now all batteries come through wet. Not sure you can get it anymore locally.

Some Motorcylce and PWC Batteriers come thru that way.

I wondered about the availability of acid too. A quick search turned up nothing for "battery acid" but plenty of sources for "battery electrolyte"

which is of course battery acid.
go figure.
