Needed a worklight, but feelin' cheap. Modded a Brinkmann Maxfire LX to 120 lumens!

My plan lately has been to purchase a Sure-Fire 6PD Defender and run either a Sure-Fire P90, Lumens Factory SR-9 or a Malkoff P60/D26 style LED drop-in in it. Despite all the flashlights I have, I do not like to carry any of them at work for various reasons. I was in desperate need of a work flashlight.

I read a thread last night where somebody mentioned Target having Brinkmann Maxfire LX's on sale for $12.99. So today on my day off I decided to go down and grab one. Went straight to the flashlight isle and it looked like they were out. Well I couldn't believe it.. so I kept looking and found the empty rack. I thought oh crap, so I looked at the other Brinkmann's, the 3W and 1W LED racks and one of the xenon's was in the wrong rack on top of the 3W Brinkmann's, so I grabbed that, the last one.

Got it home and immediately swapped out the stock lamp and reflector for a Laser Products P90 I had in an SC1 carrier. That's the easy part. Kids play actually. Now I knew I had to somehow get the dimples out of the metal insert on the inside of the body so that a couple of AW's protected R123A's would fit. I grabbed hold of the inner sleeve with a small pliers and yanked it out. I'd done this once before actually. The hard part is getting the dimples out of the sleeve.

First thing I tried was attempting to run a nail through it with a hammer to start a hole so that I could cut out the dimpled lines. That was a no go.

Next I went out to the shed and found one of my electronics toolboxes behind some junk and grabbed a really sharp cutter than looked like a tin snips. I decided I would just cut from the end, but as soon as I put pressure on to cut, one end of the snips exploded and launch across the room. Luckily, it didn't hit me in the eye! Or I would be in serious trouble right now.

So I was getting a little frustrated. I decided to get my dad's ancient dremel set down from the top of one of the shelves. I looked at it a bit and there was no cutting wheel at all! Everything but that. So I made a trip to Sears and picked up a 6 pack of Craftsman cutting wheels for $6.99. When I got home I wasn't sure they would work, but I figured out how to put them on. Then I took the sleeve, the dremel and a pair of leather gloves out to the garage and went to work on top of the freezer cutting out the grooves. After I was done I went over the sharp edges with the pliers and then used a stone polishing wheel a tiny bit.:sick2:

Went back inside and put the sleeve back into the light. That was harder than I thought it would be. But eventually got it back pretty much in place after a little pounding with a flat head screwdriver and hammer.

Result? Rechargeable 9 volt 120+ lumen light that fits in my Sure-Fire V20 holster. :twothumbs And I won't cry if it gets banged up or lost. This is not my first flashlight mod, but my first that got me this involved..

Thanks, I'm using it tonight at work for the first time. When I first turn it on, I'd say it's around 200 lumens for the few 5-10 seconds then drops to around P61 output levels or so and pretty much stays there. I noticed the lamp got quite hot after a bit of use, but upon checking the batteries, they were only just starting to get warm. This seems to be a good setup so far.

hmm, my AW RCR123s fit fine in my maxfire, just have to align those little "indentations" such that they do not line up wit the label on the cells.

I also modded a second maxfire to accommodate 18650s by removing the stock sleeve, boring by hand with sandpaper wrapped around a tool, and building a custom sleeve from copper sheet stock.

They are not as loose as the CR123's were even now after the modification, so I'm not really sure how yours fit. Would be nice if they didn't come with those silly indents on the inside though.

That boring and building a copper sheet sounds like an awesome mod, a little beyond my facilities at this point though. :)
 
just takes a lot of elbow grease, sandpaper, and the thin gage copper stock is available from hobby places like hobby lobby. it's not too hard, just takes a lot of time and patience.
 
Light is still going strong, use it every night and day. Now I'm thinking about trying to find an extender of some kind (the Sure-Fire compatible ones won't fit) or find out if I can fit two P17500's into the rechargeable version of this light. :cool:
 
You can fit an 18650 cell in the Maxfire, and you don't necessarily need to get a brass shim. Wrap a piece of sandpaper around a wooden dowel, chuck it in the Dremel tool, and bore out the body of the Maxfire. Reload the stock sleeve, but wrap it around the outside of the metal ring. Find yourself a nice 3.7 volt lamp assembly (I bet LumensFactory has a good one). I used a Streamlight Stinger lamp myself.

It won't be as bright as the 9v lamp you've got, but it'll run a long time.

That is pretty cool. How did you get the lines so straight? Mine looks like a drunken sailor did it. I do have kind of a lack of facilities though right at the moment.
 
I'm not familiar with these lights. What is the physical size of one approximately? I might have to pick one up for my wife's truck. I'd use the same setup that ampdude did so I can use CR123's so they hold up to the cold weather and awlays be ready to use when you pick it up.

You need a third hand when using a Dremel. I put the metal sleeve in a vise (Black & Decker Workmate bench, actually) to hold it still while I chopped it up with the Dremel cutoff wheel.
