I was finally able to get my hands on an M1.
Dissasembly is documented in other threads so I'll just post new stuff.
I tried punching out the press-fit polycarbonate lens, but it wouldn't budge.
By the time I gave up, it was deformed a bit so what the heck...
...Drill away..!
Free at last..
There is a ridge which retains the lens securely.
From what I could tell, there was no adhesive on this part.
The o-ring under the lens is the same size as the one between the bezel and body.
The latter has some thread locker residue which is difficult to remove, and/or may have been damaged by the heat when cracking open the parts.
The lens o-ring will be a perfect replacement. How convenient.
Boring out the business end and adding threads for a bezel ring:
I'm clueless with emitters and electronics, but was intrigued by the Arc LS Tri-Rebel mod by spc
and had a few parts ordered.
The emitters are neutral white Rebels on a 20mm star wired in parallel. I originally planned to use a 3 speed board but forgot all about it when designing the heatsink ha ha, so this time around only direct drive. There is plenty of room for a driver. Maybe next time.
The collimator is a frosted Carclo 44 degree.
The lens is from an Arc4. 22.61mm/T2.4mm, polycarobonate.
Not having anything else, I utilized the aforementioned lens o-ring but it is too small and too thick. I need something like a 22mm/T1.2mm, or maybe cut a gasket?
The bezel is an after market product (can't remember the source, but it's nice and low profile).
Other 1/32tpi bezels like the SS trit-slotted one by PEU, and SS by Leef fit too, but there is a slight variation to the threads and fit is not the same.
Machined Al can:
The positve lead threads through the can from top and connects to the spring.
The ground path is secured by a small screw.
Spring assembly is machined from Delrin with a protruding ridge to protect the spring from touching the ground path.
Finished!
For the finishing touch, I added a black HA tailguard from a run I did a few years ago.
The stock M1 is one of those oddball Surefires which is useless for us who don't kick down doors and fight the bad guys.
The most critical duties this modded light will likely see are midnight fridge raids and toilet missions, but it was great fun.
Hope you enjoyed
