I haven’t done much for the last few days but I was finally able to get back to this project.
I checked my body against a tracing of another 66 and found that very little of the wood on the sides is missing, only the edges. Thanks for your help Jack.
I decided to make a test body to figure out how to rout for adding wood back at the edge of the guitar. I also made a template to show how much wood is missing from the body and how much I need to cut out to square the body back up.
I cut a 3/8 x 3/8 rabbet in the test body to see how it would work.
I overlaid this with the missing wood template to check coverage. Looks like I have to take out a bit more for the rabbet
I've given up on the idea of bending the strips for fillers. It looks like they would be too big to bend easily. I'm hoping to use this test body to make a template to use for cutting the filler strip and for routing the body.
Feel free to jump in - I'm open to suggestions.
