Take the Flash gasket from Arkansaselkhunter and trim the front edge corners to where they are not square, this allows the flash gasket to lay into the pelican case in the Vertical position and lay flat with the inside surface of the case, for a nice tight fit. 

Use a 1 1/8" hole saw for the camera lens, and use a 1" hole saw for the Flash hole.

 Be sure the Flash gasket is as close as 1/2" from the top end of the pelican case. You will need the room in the middle for other things.

Using a sharp object, such as a center punch or Phillips head screwdriver to mark the case where the lens, and flash holes will be cut. Remove the flash gasket and put your hole saw in a drill or drill press and cut out the holes.

Use a 1" hole saw for the Flash hole, and a 1 1/8" hole saw for the Camera lens.

When you get the Fresnel lens and flash enhancer from Hags, he sends some Carpet tape, this stuff is great, very sticky, use it to hold the flash enhancer in place. You don't want to use the PT 1100 tape for this as it is to thick and will not let the flash gasket seal tight to the case.  Peel the paper from one side of the carpet tape and center it over the flash hole and stick it in place, again take the knife and cut the hole out of the tape.

Cut the flash enhancer around the outside of the grooves and install it. (Rough or Groove side in, Always)

In the picture below, mix a small amount of Epoxy, using a toothpick run a very small bead around the inside of the UV filter, making sure you seal up the

metal ring and glass together, this will prevent rain from entering through this possible area.

Next, you need to get the shutter hole big enough to accept the UV filter Ring (threaded side) Use a Dremel for this task but go very slow, you don't want to take out much.  Also there are two Ridges on the outside of the case, be sure to grind them down flush with the case and far enough back from the hole to allow the UV filter ring to sit down flush with the case.

Once the ring fits flush (below)  Mix some epoxy, run a bead of epoxy around the UV filter rings threads, use a good bead as you need this sealed up good. Set the UV filter into the hole and give it a Half a turn, this will cause the Epoxy to spread evenly and seal up all the way around.

Installing the Flash Gasket

Now get your Flash gasket out, you should already have it trimmed to fit, and get the Black silicone Gasket sealer out.

Smear the gasket sealer all over the face of the Flash Gasket, Be sure to go around the flash hole and Shutter Lens hole, all the edges, and a good bead where you trimmed off the edge corners. If you don't seal this into the case well, and you don't get the Gasket Sealer between the flash hole and shutter hole, the flash will travel inside the case and "WashOut" or Reflect back any pictures taken at night, this is undesirable.

Now simply put the Flash gasket into the case, being sure to center the flash holes and shutter holes, and press gently down on the entire flash gasket to get the Sealer to spread out and seal things up.

U bolts

Now take the U bolts and drill the holes into the sides of the case, Careful measuring is needed for this, if the holes are slightly off and the U bolt don't want to go in, slightly bend the U bolt until it starts through the case far enough to get the nuts on, tighten the nuts to draw it in, be sure to have the Flat spacer on the inside and run the outside nuts up as far as they will go on the U bolts, tighten the locking nuts up and your done. Apply black gasket sealer to the flat spacer to seal up around the holes.

Control board installation

Run the screws for the standoffs through the case. Now install the Board with the standoffs in the case and screw it down snug, snug up all the screws in the case at this point.

Epoxy the battery holder into place above the sensor

Drill a hole for the Toggle switch, this step can be left out, it depends on if you want the ability to disable the cam when you walk up to it, or wait till you get it off the tree and open the case, I prefer to leave it inside, but I will put this one to the outside.

Rubber boot gasket

The Boot gasket that you pulled out of the case at the beginning is now needing to be trimmed back, with good scissors cut the gasket 1/4" from the edge all the way around, what you have left is the seal for the door on the pelican case, put the seal back into the case and that's it.

Slide the Desiccant pack into the bottom of the case and your finished. Do not fasten it, when it is no longer able to absorb moisture you can place it in an oven for 3 hours at 300 deg. and it is good to go again. this will protect the electronics.

I also found out through trial and error, you need to have a way to secure the camera inside the case, You don't want it falling out and onto the ground when you open it, as it might destroy the camera...Go to Wal Mart, in the area where they keep screws, hooks and other hardware, look for the plastic hooks for hanging pictures, the cheap ones that stick to the wall with double sided tape.

Trim one down short and the other two leave like they are...Epoxy them into the case and use a rubber band hooked to them and over the camera. You can see them in this last picture of the completed cam (minus the Rubber band). and here it is, all that work finished and working, ready to find you a big buck, Turkey or to just see what is going bump in the woods day and night.

Now camo the outside of your new Trailcam and get it into the woods.
