Im unable to update the original thread so im starting this one to show the completed cover and additional steps to address the many PM's im getting asking for more info on the project.

After penciling the outline, it was time to paint.

One down, one to go.

While the primary concern and reason for this project is bed security we hope to make the folding cover as weatherproof as possible considering the fact that we have 3 sections and hinged joints/gaps. To make sure the seams are as small as possible the hinges were recessed in the wood.

To further discourage rain from entering through the hinge seam we thought the gap could be filled with flexible silicone rubber caulk. In order to make the seal as tight as possible the plan is to use a caulk gun to apply a bead (or beads) of caulk to one of the sides of the hinged joint and then close the cover causing the caulk to ooze out and fill the gap. To prevent the caulk from sticking to the other half of the joint, we applied a couple coats of paste furniture wax and buffed it. Once cured, the gap would be filled with flexible rubber and it wont stick to the waxed side of the joint.

The perimeter of the sections that come in contact with the side of the truck bed will get adhesive backed, rubber weather-stripping. This will quiet the vibration/noise that would otherwise occur between the hard plastic and the painted wood. It will help keep the paint from being abraded and will provide additional sealing from rain. It pretty cheap so if it wears it can easily be replaced.

Keeping the sections closed will be done with spring loaded plungers. We picked up a 10 pack on Ebay for $8. They have a lengthy throw distance but the handles were on the small side so we increased the size of the handles with short sections of micro diameter arrow shafting and J.B. weld. The nose of the retractable plungers will fit into holes we drilled through the hard plastic bed liner and metal of the bed. We used a 1/4" drill.

Because the sections fold onto one another I cant have a hard handle so we fashioned a handle from left over webbing.

The finished weight is 55 Lbs so its easy enough for one person to remove.

Here is a video showing how to install and remove the cover.

I think is was locked due to being off topic.

I do think we should have a "special projects" forum for things that we might be interested in that may not be a perfect fit in any of the forums we generally play in.
 
This cover was made for hunting purposes. We hunt public land and need bed security. Likewise our hunting gear needs protection from the elements. It was created because I am a hunter and need for hunting trips. Its perhaps the most hunting related item we have made in some time.
