Very nice. I am dying to do this. Any chance on doing a "how to" on the actual anodizing process?

Yes Eric, I'd be happy to. Although, it may be a while before I have all my ducks in a row.

In the meantime, you should watch the video Tom did using his anodizing bench. You can watch it here:

Best of luck I gave up on it 10 yrs ago really hit and miss over 3yrs.

Did have a twin digi psu but kept packing up so went for the analogue Maplin one Tom uses at 14.4v.

One major problem I used to have was electrical breakdown. No way could use wire wedged in to a part, best had was around 5 mins as anodic layer built up between the two joints. Ended up filing anodising off aluminium 6082 and forcefully wedging in to a hole. Pro anodisers use titanium sprung clips of various styles hence why theres always a scratch area.

Up to the last 10 years there was literally 5 sources of information on how to and they all told a vastly different story in every process often missing vital info. Done hard anodising twice.
Dyes were one concern, tried everything I could get my hands on eventually settling on a powder what the pros use. Fairly sure it was around 90 degrees any higher it sealed the parts or turned it maroon to brown. Used fish tank thermostatic heater, cheap.
Ampage used to drop within 2 mins of putting part in, something like 5" round drawed in excess of 6A, after 2 mins down to sub 2A.

Still got the small 1foot fish tank the 4 foot x16" high level one my nipper broke, gallons of 21% sulphuric escaped. Use one of two pros now but theyre stinging me £40 cash for a few parts or loose a vital part or even scrap the jobs sent in that took months to produce.

Last link above is called splash anodising no need to do what he did, pros just flick something across the part hence the term splash.
