I should have specified not viable in lights that don't have removable pills. I think it would be fine for typical pills, but the softening threads could be an issue.
I think wight is correct that it will probably be fine to do without annealing. I like the idea of an "anvil" set for flattening pills. Probably would be very popular item around here. I find pills are not flat much more often than flat.

How do they do this sort of finish work in reputable machine shops?
It’s commonly done — cutting holes into a piece of metal from opposite sides,
and ending up with a flat plane surface in between the two holes.
Does it take a couple more passes with a grinder and finer abrasive, before anodizing?
Or put it into a hydraulic press and anvil, stamping the piece flat where it should be flat?
This can’t be a new problem in metalworking.
Is it something they’re not doing in China yet?
Or are we getting the discards, and some other buyer getting the properly finished work …?
Reinventing the wheel, reinventing the plane, reinventing everything. What’s the problem here?
Easy enough to check for proper contact, just slip a bit of carbon paper in and rub the parts and look to see where they did and didn’t touch. (Does anyone still make carbon paper?)
Remove the LED
Remove the driver
Get an “anvil” with a good enough flat face that would fit up inside where the driver came out, and rest against the plane surface.
And put it in a press with another “anvil” held at exactly the same orientation down through the front
And squeeze.
That’d work if the metal flows enough under pressure (if it’s close enough to even thickness all across, just ‘dimpled’)
But if both surfaces are a bit concave — it won’t.
Thanks downlinx, did you just a quick test or have you used a whole set of batteries in it?
On one of the customer pictures there is a Adapter shown:
Not sure if it is a 3 or 4xAAA but any of the guys who have bought one could easyly tell, I cancelled my order so I never got one…
I would be interested in a tailcap reading with Alkalines and with lithium primaries and the overall impression how it works for a usual guy.
That’s my picture. It’s 3xAAA, I never tried it with that config, it is a 26650 flashlight and I will not run anything else in it. The flashlight is good enough with great potential. Maybe I will mod it soon. I can’t measure tailcap reading because I don’t have a good enough multimeter at the moment.
I’m really having a hard time judging size from the pic’s, I actually didn’t even know it was 26650 till just now, can someone provide bezel opening (as well as head opening, probably a few mm different) measurements please?
