You are correct about the jointer not being the tool for this as it has a nasty habit of putting a slight bow in the workyou were trying to make straight.         Best       Dale Erwin <BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px"> Dale,     I think I get it now. You were talking about making a straight edge truly straight. Am I correct? For that I prefer to use a router. I know that most folks immediately think jointer but I've had very little luck as the ones I've been able to afford have had short beds and have left not so straight an edge and quite a lot of snipe. Since then I have taken to a 10' system I made from aluminum channel and a straight edge from aluminum box to have the router follow. A commercial type of this is made and called "Joint-a-bility" or something with very similar spelling. I have had good success making 2 boards wind up flush with each other over their entire length with no clamping whatsoever. I hope this is what you were talking about. If not, I am lost. Greg BTW - only one "g" at each end.
