Just emailed the Blueprints you. Let me know if you didn't get them. I have not made one so can't really help you with any questions. The one thing I would say is try to make the height adjustable since kids very so much in size. GL Hope it works, my son's team could definitely use one. They all stand straight up..
Is it possible to get plans for a blocking sled? I coach in Australia Yes they play gridiron down here) and would like the teach my line the proper way for block and work as a team. email@example.com
