I'll list my issues from first image to last.
The first two images show problems after glue up. I noticed the metal or paint on the metal off the clamp was coming off and seeping into the wood quite a bit. So when cleaning the glue off while still a bit soft, I had to go a bit deeper on these parts with the chisel. I really took my time there still and I was taking really small shavings off. However, the sapele part of the panel seemed to gave been just ever so slightly higher, and when trying to go with the grain on the walnut border, I chiseled across the grain on the sapele. And it looks like there's minor tearoit there now. What might be the best way to resolve this, or will sanding do the trick?
