maybe so Jim, but
How to you flatten the width of a board with cup or twist on a tablesaw? Maybe I should just ditch the 12" jointer and the 2 - 6" jointers I have, cause I must have missed something in the instruction book. Also Grizzly has about 10 pages of jointers in their '09 catalogue, including a massive 16" at $5695.00. You might want to contact them and tell them about your method. :yes: billI found a good ripfence and a great carbide finish blade will give me straight boards with no tearout on nasty grained lumber much faster than a joiner. The joints are so good I use this method to join table tops and all other glue up projects. First rip with crown edge to blade and it's already straighter than several passes on joiner. Flip and rip with straighter edge to fence. It's the same principal as using a joiner from here, straightest edge goes to fence to cut straighter edge on blade. If you're straightening alot of lumber, use a rougher cut blade for first few cuts on all pieces first, then finer blade for finish cuts. Happy joining!!
