I have several 12 foot long by 6 inch wide planks of WRC that need to have one true edge cut before I cut my strips. I only have a table saw available. I've searched the web and found 3 different methods.

Rehd's Board Straightener: http://www.dbeweb.com/kayak/pages/rehd.html
Cummins Board Straightener: http://www.woodcentral.com/shots/shot12.shtml
Table Saw Jig: http://www.glen-l.com/wood-plywood/plate10h.html

Rehd's Board Straightener looks like it requires a fine touch on the table saw. The other 2 require long, straight edged and flat stock (near impossible to find) to make a jig.

All of these methods look like they would work, but in my hands I'm afraid they would give marginal results.

How do I true one edge ... and do it well ... without wasting a lot of stock in the process? Is there a better way than any of the methods above?
