A few years ago I made a parallelogram mount for my 10x70 Fujinon Binocular. Now that I have a new to me APM 100mm binocular I decided on a more robust mount using aluminum stock I obtained from flea markets here in CT. I don't know what the maximum weight it will carry is, but it was a lot less expensive than any of the commercial units. The only tools used were a cheap Chinese drill press and a hand hacksaw. A few small hand bandages later, I have a decent mount.
