Super long Huntlight FT-01 - run 2x 18650s!, and Momentary!

In case anyone's interested, the Streamlight Scorpion body fits into the tail of the Huntlight FT-01 perfectly. The Scorpion body fits a 17670 cell easily, but can be bored to fit an 18650 also, so you can run your FT-01 on 2x Li-Ions for hopefully much more runtime (if it's a buck regulator, runtime will increase with higher voltage). Also, because the Scorpion has a momentary clicky, this also turns the FT-01 into a momentary LED, which is a nice feature. Anyways, here's some pics.

I just tried this, and it's not working for me. The Scorpion LED body screws for about two turns, and then doesn't go any further (the stock tailcap screws on almost three turns). Also, I can't seem to fit a 17500 in the Scorpion LED body, either.

Here are the possibilities I can think of:
-I have an older or newer Scorpion than you do.
-You didn't mention using the LED version of the Scorpion, so maybe there's a difference between the incan and LED versions.
-I'm using AW's newest protected 17500s, and you're using some other kind of 17670s.
-Perhaps 17500s are slightly wider than 17670s?

Oh well. It would have been great to have a long-running, fully regulated Huntlight.

Mine stopped after 2-turns also at first, but I knew the threading doesn't change pitch all of a sudden, so it must fit and all I did was wiggle the Scorpion tube back and forth (twisting) until something gave (maybe some build-up?) and the Scorpion tube screws all the way now.

Scorpion xenon and LED bodies are identical, so no difference.

Your 17500s may be a bit fatter than mine. I actually don't have any 17670s. I had an 18650 in the FT-01 tube already and stuck in a 17500 the Scorpion tube with a spacer at the bottom just to test if it made proper contact throughout and it worked, momentary and all.

Too bad FiveMega doesn't sell the 18650 barrel anymore:

The stock Scorpion tube looks to have enough metal to bore out to accept 18650s.

The wiggling worked! Thanks, jsr!

A Scorpion body has an ID of 17mm, and an 18650 (AW, protected, stickerless area) has an OD of 18.2mm, so removing a mere 0.6mm all around would accomodate an 18650. It looks like I have some boring to do! I'll ask modamag about it the next time we have a BBQ.
