Not real sure if "fixing something" fits into the "Making Stuff" area, but I have sorta been working on a older Mag-lite that had badly corroded batteries.
Really made me sick, as I do check them real regular, and have had this one for a long time.
Anyway,
Step one, get old batteries out.
Clamp barrel in vise, unscrew base with pipe wrench.
Soaked in vinegar, screwed long deck screw into base of the first battery, clamped the head of the screw into a vise and pulled/worked the first one out.
Same with second.
Step two, clean inside of barrel w/vinegar on stiff bristle bottle brush, then brass brush. Wipe out with rag.
Let dry.
Step three, Clean out threads/spring w/brass brush.
Step four, Put in fresh batteries, wipe inside of barrel and threads with dielectric grease.
Back to work................for now.
It has been my experience that once the aluminum starts to corrode, you have a heck of a time stopping it.
Tried to order a new barrel from Mag-lite by, haven't seen anything back yet, appears maybe "no longer available"
Check your flashlights.............................!
