Gday everyone,
I've been given a Brazilian rosewood bridge blank with diagonal grain running lengthways at about 15°. By skewing it, with a tight bridge, I could reduce it a a little. But would you? How important is grain in this direction?
Vertically, the grain is near perpendicular.
Many thanks for your views
James

The thing some people watch for is the orientation with regard to splitting in the area in front of the saddle. The greatest vulnerability to cracking is in the direction perpendicular to the grain as you probably know, so it's forces that stress that axis that you want to avoid. I've seen discussion about that either here or at the classical forum.

In any case any resulting effect is on how you work the blank in cross section, to the extent you have a choice. The angle as seen from above isn't the issue and may even be slightly protective. But my lutherie chops never yet extended to guitars so take me with a grain of salt. [;)]

Oh my…

I think you woke be better off saving this for somthing else.

That bend in the grain on the left corner is a big issue.

Still, square up the block and see how that goes. I saddle slot with a full block first with a table saw but if you use a chisel or anything else it’s going to be a struggle. Goes without saying care must be taken with any bladed tool.

I think if you can make it a bridge without a corner “checking” off it might be worth glueing yo a top, regardless you’ll learn somthjng even if it hangs on the wall unadorned as a reminder.
