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.
