Step 6Shrink wrap!
Using your two pieces of shrink wrap (make sure to cut them so they overlap about 2 inches!) start shrink wrapping.
- remove batteries from laser
- apply epoxy to the cap w/ lens around the equator of the marker piece (mid way down, don't put too much, but make SURE it's enough to get a seal!)
- slide shrinkwrap over the piece (see first and second picture) and shrink the portion over the cap down, leave the rest un-shrunk until the epoxy has dried.
- Slide your laser in (aperture side forward!) and shrink all of the piece down to the laser.
- let cool
- repeat with the other end cap (obviously have the closed side pointing out) I would suggest having the shrinkwrap hang an 1/8 of an inch over the end of the cap. This is so it seals well AND covers all the highlighter. It's a nice finishing touch that will make the laser case look that much better.
- (back on the other piece with the lens) using some more epoxy seal AROUND the outside to shut the gap between the lens and the shrink wrap.
At this point, you're done! You should have a nice seal, and should feel resistance when you try to remove the pieces, not TOO much, if you CAN'T remove the laser, heat the shrinkwrap up again, then pull out while hot. Now it's time to test it!
