I got some outwales from OT for my 16" yankee but the rabbet they cut is at a 45 degree angle. What is the easiest way to recut the rabbet to a 90 degree angle like the original? One of the problems is the outwales are bent so it's not easy to use a table saw and dado. Also the bend is not like the canoe, so what do I need to do to make them more flexible to conform to the canoe? I am very new at this so please excuse my lack of knowledge.
