My custom parallelogram mount

Heres my first attempt at a p-mount. Its foundation is a CST/BERGER 60wdf surveyors tripod(southern tool.com $160.00) Then I fabricated a custom adapter from the 5/8 thread of the tripod to a removable plate and sleeve setup that has thumbscrews that allow my P-mount to swivel 360 or lock in place. The p-mount has a vertical range of 4 feet, it can inclinate to full zenith or lock at any angle and also pan left to right about 30 degrees, all with teflon washered thumbscrews. When I lock it in the horizontal balanced position and remove the 25x100 Oberwerks I can simply lift the P-mount out of its sleeve and replace it with a sleeve that has a Bogen 501 head(thanks edz).The p-mount has a dampening time of about 5-6 seconds on my deck and even less time when I set the tripods legs into the ground with its chains tight. It has 18 and a half pounds of counterwieght and more can be added under the tripod to really make it solid. I hope to have more pictures for everyone very soon but i had to borrow a friends camera to get this(next purchase!!)I really enjoyed building this and this one is my prototype I hope to improve on it on my next one. As far as material i believe I spent about $70.00 but I still have some parts I didnt use to return. If ya have any questions feel free to ask Id be happy to help you on your own mount. Thanks everyone and this site for encouraging this amatuer binocular astronomer!!
