New to the forum and new to the table saw. I purchased the Ridgid 2400 and love it so far. I am pretty comfortable with using my saw but I have a question I can't seem to get a reasonable answer on. I am building a built-in bookcase and I am preping to rip down the 4X8 ply to start building the carcass. Trouble is that after meausing 12 ways from Sunday I don't believe my $40 sheet is perfectly square as provided from the factory. Obviously if you put a wavy edge up against the fence your result will be a wavy cut or worse....Is there a tip/technique that can be suggested that can be used to ensure cutting a straight edge? Can anyone suggest a good book that would cover solving problems such as this? One suggestion I received was to attach a straight edge to the sheet to use as a guide against the fence but I don't know about that....
Any suggestions would be great and thanks in advance for the help.
