If I only have a few boards to straighten out, I take a narrow straight board, or piece of ply, put it on top of the board with the straight edge hanging off one side, and then shoot a few pins in it hold them together. Then run the true edge along the fence of the table saw. the pins are strong enough to hold them together but pulled out eaisily enough. You wouldn't want to do a whole bunch this way, as it is time consuming. I have a lucas 827 and have found that it is easiest to mill 1/2 a log as a base to work off of if you are going to resaw or straighten any stuff, otherwise squaring up you're stack of boards becomes time consuming.
