This is the part where I messed up. I should have come up higher on my initial Plank. Short of redoing the entire thing, I’m going to make a filler Plank for this gap.
This is one thing that I love about this hobby. Because when you run into situations, you have to do what the Marine Corp doctrine dictates… I.A.O. Improvise Adapt & Overcome
Anyway, while driving to my doctor’s office, I thought of a way to make a template for making the filler Plank. I’m going to use a big piece of clear Scotch Tape and trace the gap onto it. Then, I’m going to bend the Plank around a Jig that I made and once these wood takes the bend, I’ll simply last the tape on to the wood and trace around it and sand it down to fit.
Mind you… This is all experimental. I’m in the process of repairing this Gap by making this shape of internal Plank.
