I did not think about that, I have seem many repairs made this way, its does make sence that an
straight grain patch can cause problems, in this case the patch is being feather in all 4 the edges, and its also small.
I suppose next time that If I do an square patch make sure it doesnt align with the grain, or make it oval.

Arnold! Any advise on the bass bar placement ???

Yes. It goes on the E side.

Ba-dum-bump!

Seriously, you want to first choose your bridge width. In general this is not much wider than the distance between upper f-hole eyes. Then you lay out the bass bar so it is slightly outside the center of the bridge imprint. The angle cannot be set by the violin-maker's method because basses are not standardized. I personally like the distance from the center line to the bass bar to be a bit more than half at the top what it is on the bottom.

That's some great info Arnold thanks...
Two things:

-I got tree bridges, the bridge of chooice should be a medium side bridge, just to be safe.
-The My understanding is that the BB length is 7/8 of the top length.

Did you chalk fit that Bar 100% flush with the Top? Looks like it's gaping all over from the pics.
