Let's see what you did with that Bar. Was it angled slightly across the grain from top to bottom or straight with the grain? Is there a crack under the bar or only up to the bar at the bottom?

I did shave it a lot just enought so the bar let the top to sit in a flat surface to make sure that it's flat:

Original:

a small crack in the botom

Question, this is where the old bass bar used to be, I am thinking on putting the new one right on the same spot, but is the bar could be way to align with the top grain, that could cause a crack later on!!!

Scored lines? Black ink?

The shadow of the oxidation difference is plenty enough to see where the old bar was for reference regardless of where the new bar is going.

No ink just pencil marks, but should I place the new one on the same spot?

I can't see top to bottom well enough on a straight line but if not angled, angle it slightly more. There is a formula I read years ago for this but forgot where I read it. It has to do I think with the length of the bass and possibly the width. Not sure. Ask Arnold or Jeff. They have dome more 'correct' bars than the average 10 or more luthiers.
