I built the one mentioned by rrbrown in post #9 above. I have used it a lot this summer. I couldn't ask for anything better. It requires only the pulling of 2 levers. The bench is very heavy, but even when loaded down it rolls as smooth as silk with one finger (on smooth concrete). The only problem I have had is that the dowels through the cam come lose in the cross piece behind the cam. They were glued in place but they are under a huge amount of stress. They need to be secured better. The ONLY effort required is caused by the friction of the cam against the bottom board. The cam and the bottom board that the cam rides on are wearing. I recommend mounting a metal plate on the bottom board to reduce friction. It would be nice to make the cam out of melamine or what ever that slippery plastic stuff is called. Or a roller bearing in place of the cam would be the cadillac version. Think I'll work on that this winter, that is if it gets over 20 degrees this winter in Michigan.
