Does anyone know what thread size the mounting hole on a Moultrie M40 is? I broke one of the strap holes off my camera and need to find a new way to mount it.

Not real sure about the size, but it's the same as any other digital camera or camcorder.
I had my M60 set up on this sony tripod when playing around with it at home..

It's 1/4 x 20. Get yourself a 30 inchsection of a regular (or treated) 2x4. Drill a 5/16" hole in one end about five or sixinches deep and a3/16"in the other end about two or threeinches deep. Hammera sixteen inch piece of 3/8" re-bar (or other steel rod) in the larger hole and file or grind a point on the end so you can push it into the ground. Get a two and a half inch long1/4" hex bolt and cut the head off. Tap that in the smaller hole in the 2x4 so that about 1/2" of threads are exposed. Push the stake in the ground where you want it and screw your camera on top. Works great.

Thanks guys. Sounds like that would work nice. I wanted a way to set it up in a foodplot anyway.
