For awhile now I've been thinking of making a camera mount for the car so when I go out driving I can record it for friends or just myself. Not so much a LowNSlow kill documentary (as I don't race) as an in-car-camera for whatever outings I feel like going on. I'm sure this has been done a million times before--probably "designs" very similar, if not exactly, like mine, so don't expect anything new and exciting! :)
Luck had it that I had a bunch of spare wood from some crates a taxidermist used to send me some of my deer heads from last December. I was breaking them apart and figured I'd salvage some of it and give this a prototype-style go. I wanted to make something that clamped to the two bars that hold our headrests in place.
I really just took some wood and held it up to the head rest and marked it, measuring later to sinc-up the second half.
The wood I used was two pieces of what I considered at a glance to be 2x2, two pieces of what I considered to be 1x3 and a giant hunk of 1/4" thick pressed board (not sure of actual "industry" name).

I cut both the 2x2's and 1x3's into 11 inch strips--the number 11 simply being where I had earlier eyeballed the needed width of the headrest. With this length it would easily cover slightly more than the entire width of the headrest. I then glued and screwed one piece of 2x2 to one piece of 1x3, and repeated it for the remaining pieces.
I now had two identicle pieces to use as the clamps--one piece would go on the front of the headrest, the other on the back side. I would use some bolts to hold them together. In order to make a more secure fit with less sliding I decided to make tracks in the pieces that would wrap around the bars in the headrest.
To do this I used small shop clamps to hold the two pieces togther (see picture) as they would be once the bolts were installed.

I then took a headrest out of the car and marked where the two bars sat on the pieces--eyeballing the center. I went to my wood drill bits and decided on a diameter that was slightly smaller than the actual bars. If I chose an equal size the bars would fit either just flush or slightly loose even with the bolts in place. With the grooves smaller they would "hug" the bars and still maintain the ability to tighten or loosen their grip with the bolts. I chose 5/16" Here is a picture of the pieces still together with the bars marked and holes started. I drilled right where the two pieces met so the hole would turn into an equal groove on each side of the bars when seperated. When they were clamped together like this is also when I drilled 4 bolt holes--the ones that would eventually become MY clamping system once it was done. Doing it while clamped, obviously, ensured everything would line up.

I cut the hunk of pressed board to a 12x9.5" rectangle. My camera is about 9 inches from front to back, so the additional 3 inches of length was that plus extra room for the above pieces which the board would be mounted to. I glued and screwed the board to the 1x3 portion of one of the pieces--assuming that the larger the connected area was the more stable it would be. The following pictures show it already together, but also illustrates how the board was connected. Where the board ends is where the two halves seperate and clamp to the headrest.

Once everything was attached and the holes were drilled for the mount, I got the hardware needed. I measured out the dimensions of the entire thing. The bolts needed to hold it together as a clamp would have to pass through 3" of material (ends up my 2x2 was a 1.5x1.5) and still have enough thread left over to use properly--4" was about right. Arbitrarily I chose 1/4" diameter for the holes, and thus the bolts. I put the bolt holes on either side of each headrest bar (4 holes total). This is probably overkill, but I'm one for "too much is better than not enough". I used the proper washers and wingnuts to finish the clamp issue. Pics with and without the headrest clamped in:
