Hi all - was hoping to get some advice about a project I'm working on. I'm building a banquet in my kitchen have completed the lid but need to put a backing board that will be connected to the bench but I'm finding different lengths at various parts of the bench that is causing the problem. See pictures. For example in one part the gap is approximately 4 inches and 5/8 and in another part it is four and 3/8 ". Should I cut the board straight at the smallest width or should I try to make it align to the wall where I would need to cut a different lengths. would appreciate your comments and suggestions thank you.

I put the board against the wall, these shoe the gap really good. It's bad!!

Use a compass, (circle drawing type) and set the pencil 4&5/8" from needle.
Keeping it perpendicular to the wall trace a line on "backer board" holding the needle end against it.
You can cut with band or jig saw.
I use a belt sander for this, with belt in upright position, you can really fine tune it.

Can you elaborate? I tried it and when taking measurements the line is off 1/2 inch or so.
