Flashlight Bor(e)ing
 

Does anyone in Canada do or know of someone that will do flashlight boring to mod CR123 sized flashlight tubes to the 18650?

Really depends on the outside diameter and shape of the existing tube. 99% of the time just not worth it. With the material available it's something any machinist could do or even a clever DIYer.

I have 4 surefire lights I want to have re-bored

Would prefer to have it "professionally" done. Many of the modders in the states won't touch Canadians lights (ITAR) or other restrictions imposed by surefire or some federal agency.

If you've got the room to bore them out, I can do it =p
