CNC-123 alloy?

[Halibut]

Does anybody happen to know what alloy Dan used to make his CNC-123s? I'm assuming 6061, but can anyone here confirm?

Thanks, CPFers!

He answered this in another thread. It is indeed 6061 (-T6 I believe?).

Yup, 6061 T6. The favorite aluminum alloy of flashlight modders. /ubbthreads/images/graemlins/grin.gif

Jon and Mark,

Awesome! Thanks for your help. The little guys are being dipped into electrified sulfuric acid as we speak. /ubbthreads/images/graemlins/smile.gif

make sure you mask off any areas that need to make electrical contact.
Anodizing is non-conductive.

Dan,

Hopefully. We'll see when they come back from the friendly neighborhood anodizer.

Dan (or anyone who knows /ubbthreads/images/graemlins/smile.gif),

So what is the best/easiest way to mask threads etc. before anodizing? Are there different requirments for typeII -vs- typeIII HA?

Thanks!

I haven't done it myself, but I have heard that there is this stuff that you can paint on and it will survive the acid, and then you use a solvent to remove it.

You can also get a paintable masking that peels off once the processing is done. That's what I use to mask the threads on the parts I do - it's like a rubber cement type of stuff. It is nasty-solvent-based, and so I have to do this work outside, as I don't have a chemical fume hood in my basement... /ubbthreads/images/graemlins/smile.gif

Hmm... I did find the rubber type stuff on-line. The smallest available qty was way more than I need. Maybe I'll try to find it locally.

Has anyone tried something like nail polish? Or maybe "liquid electrical tape"? Both of which seem to be a nasty solvent based stuff. /ubbthreads/images/graemlins/smile.gif
