Thinking of a mount for binoculars

I'm thinking of building a mount for binoculars. Especially if I wind up buying something with more light gathering than the 10x50s that I use now.

I'm looking at a parallelogram mount for a tripod. I first found this one. It has a nice bill of materials and drawing. I checked out most of the stuff at Lowe's, except for the teflon sheeting. But I'm probably going to blend it with ideas from this one from the cloudynights.com forum. I really like the extra degree of freedom to pan left and right.
