RE: Dummy battery? Not for the 1185 in a 3D body.
Juancho was talking about the 1318 (1331) which runs on twin stacks of 4x123. 4 123 batts end-to-end takes up less space than 3 D batts, so somehow we have to fashion a spacer/dummy to make up the difference. As noted in the pic, you'll see a plumbing endcap with the D cell top taped to it. For Juancho, this becomes his spacer/dummy.
M@g Trivia: Twin stacks of 4 123's do NOT fit in a 2D
M@g lite because of the tailcap threading onto the 2D body, a single stack 4x123 will. /ubbthreads/images/graemlins/thinking.gif

Sometimes I feel really stupid, but it's still not clear. You said, above, that 4 123's take up less space than 3 D batteries, but that's what a 3D Mag has in it. You also say you don't need any dummy for the 1185, but as I understand it you're running two stacks of 123's, each of which are as high as....4 123's. Assuming you are adding a washer on each end, with the appropriate ends, it still seems like there would be too much room in the 3D host for (one or two) stacks of 4 123's. Is the issue the spring? Also, what specific kind of washers do you use, or does it make a difference? And finally, what about the 2AA that pushes the brightness? Where does it go? Sorry for the density....
