Okay kids, buckle up. I got a package today. From THE Don Keller. The man who invented the heavy duty police flashlight.
Original Maglite switch hex key...
This was the sight inside the head of my old light before I did the switch replacement. There was some serious hammer and pin-punch action to blow the old switch remnants out the tail of the light...
MUCH cutting and judicious hacksaw usage to remove the old ring frozen in place...
Got it cleaned out...
Beautiful new parts from Don. The sharp-eyed Mag Mechanic will notice it's missing the positive battery terminal that touches the top of the first battery. I looked everywhere, I checked the box 50 times, I checked the floor. I had an email teed up to go to Don and I figured "Wait... I'm sure it's all here" and I shook the head. It was stuck inside the little tower under where the bulb goes.
Moment of truth...
My number one concern was damaged threads inside the light from getting the old ring out. After careful chasing the threads with some right-angle picks and dental tools and careful cleaning, I threaded the new ring on a bunch of times by itself to test, backing up every couple turns with a good puddle of mineral oil to clean out and chase the threads. To my relief I was able to get it all the way down.
Check the head out on this baby... I've never seen a machined "dished" contoured shelf inside the head before....
Okay, go to fire it up and it doesn't work. Hmmmm... no panic, no fear, disassemble, remove ring, remove switch, take it apart, check the spring location and the little ballpoint pen clicky switch, drop the switch on the shop floor, crawl around on hands and knees, reassemble... THE LITTLE HEX SCREW! I put it all back together, tightened the hex screw deep in the center of the switch and KAPOW! THERE WAS LIGHT! AND IT WAS GOOD! (Just for reference, this is a PR-base LED drop-in bulb)
Thanks again to Don for reaching out with the parts and including the hex key and a new rubber button. Proud to have a Mag with parts that have some serious history!
