Has anybody made an extendable graph mount out of a trailer jack? I thought about buying a cheap one & removing everything from inside it. Adding a plate to attach to front deck or a heavy duty ram mount to be able to fold it down & add a plate to other end to attach the gimble mount to then drilling holes up the length of jack to be able to raise it up & pin in place to get graph kind of level with your face. This would sure help the sore neck i'd think. If anybody has done this how have you liked it? Thanks
