I have worked in dirt and jack stands sitting on a 2 x 8 too many times. I have a color bone that is noticeable out of "whack". don't ask HOW!!!! hint....and ( one time I can't blame a horse for my misfortune) ......please get a sheet of 5/8 or thicker plywood to work off and BE sure to chock the rear wheels so it can't go forward or backwards!!!! just be safe.
