Okay step one question...My HS-907 doubler is warped lengthwise that when you set it on the table the middle is about 3/4" off the table (imagine what a bridge would look like). I thought this may have occurred when they cut the doubler and drilled all the holes at the factory so I carefully bent it straight. Then I thought should I have left it and just clecoed it as the directions said, or was the warp a problem that I should not have corrected? Thanks in advance for any help.
