The Indigo Flow, anodized Ti, RCR123, click flashlight–WIP

Thanks to darkzero on CPF, I was able to get a couple more bars of diagonally knurled Titanium.

My hope is to anodize the diagonal knurls, as well as the axial grooves on the light, but then to take off the anodizing on most of the surface, leaving just the cut portions of the light with color.

Something like this rendering, but probably not those colors. I still haven’t decided whether to use only a color, or two colors, i.e., the large angled grooves could be different from the diagonal knurling.

I’ve started work on the Ti bodies:

Here the three pieces have been screwed together, the tail cap, the battery tube and the head. Since the tail cap and head still have some machining to be done to them, the proportions are a bit off.

Some close-ups:

The anodizing is the big unknown–it could look nice, or not so nice–in either case, I’ll have to live with it. 🙂

1/17/13 Update:

A little more machining to complete the light–first, the tail cap needed to be beveled. This bevel reaches down to the rubber boot of the McClickie switch that will be installed:

Next, I had to part off the head from the stub that was used while most of the machining was being done on the head:

Stub is on the left–inside the collet. The head is now separated from the stub and has been ‘caught’ by a bar inserted into the head. No need to ding the piece by letting it hit the lathe!

Then the top of the head needed to be beveled down to the lens:

And here are some shots of the light, after some light sanding:

UPDATE — 1/29/13:

Anodizing went well–I like this blue. Most of the anodizing will now be machined off, leaving only the knurling and the grooves blue.

UPDATE 1/30/13:

Excess anodizing was removed:

Next up–a retaining ring for the McClickie switch and the building of the light engine.

Copper Light Engine which holds the driver, the LED and the reflector.

Cree XM-L, which was soldered onto a copper MCP has been installed in the Light Engine, using thermal adhesive.

1.5A driver was installed in the bottom of the Light Engine; once the reflector was inserted, the Light Engine is screwed tight into the head of the  light, compressing the 2mm thick mineral lens against the O-ring, thus sealing the light from moisture.

The Indigo Flow has been sold in a private transaction.
