finally opened a JM35

Flashlight Modding and DIY Parts

Hey guys!

motivated from a guy (who destroyed his JM35 while opening) i tried again.

i did not fear failure and went the hard way…

the switch is press fit and after i managed to remove it with a new alligator wrench i found threads underneath…

so i removed the reflector and the MCPCB to damage as less components a possible i the worst case.

i used a file to flatten the retaining ring in the head on opposite sides to get better hold with my hand tools
(the vice clamped to my bench did not hold the force and slipped off)

using a heatgun to bring it onto 160°C (IR-thermometer), a long wrench and a big screwdriver through the longholes did the trick
took me a lot force (and i do not think i am weak) at the end - i was standing with a foot on the screwdriver while opening the head!

before i slipped off the filing did not look like a drunken monkey was working here… :wink:

i am sure thats the maximum amount of thread glue a thread can handle…
the guys did a great job cleaning it up after assembly!

there is even a Oring !

and here is the boostdriver:

behind the (blue) LED- wire is a 40 mOhm resistor :wink:

since i am more a tryer than a thinker :wink: i hooked a XHP35 to the driver…

gave me only 11,6 V which resulted in 0,48A
any idea if it could be possible to push that?

Lol, it looks like mine . Such a shame to destroy a nice flashlight. There is no way to remove driver without destroying the body. I was so angry when I saw amount of glue and aluminum residue inside. Sorry, but I completely forgot to send you pictures of my destroyed JM35. When failed to open mine I got so pissed that I hacked mine in half with a saw just to see what is inside.

Aftermath:

Driver looks like an updated LD-35

I was really thinking about buying one to use as a host. The shelf is large and I like the “retaining ring” but I do not want to damage it to take it apart. Guess that one is off the list.

Thanks for your hard work and effort guys.

Damaged and ugly but not destroyed! Thanks for the tear down

What the hell is the point of glueing the threads? If anything it’s labour added that does not add value.

i was thinking i take one for the team :wink:

after scratching the glue residue off with a tiny screwdriver the threads are easy going…

-> if you plan to kill the driver anyway heat the whole head up for a long time to soften the glue

I think i maybe find reason why my shadow is not working

Pity it took so much work to bust open.

The Shadow JM35 MT-G2 (2x26650) is one of my favorite lights. Form-wise, it’s kind of a throwback to when D-cell Maglites were king. But it has a nice beam, is plenty bright, and is well-balanced for such a hefty flashlight.
