saddle slot

How much do you leave wood from the saddle slot to the front side of the bridge?
4-5 mm? My Marin has only a bit less than 3 mm.

Less than 3mm is risky IMO. I've seen one bridge where the front of the slot had broken off as a result of being made too thin. Depends on the wood used of course, and also the geometry (break angle and height of saddle above the slot), but generally 5mm is a safer bet, and I don't know of any advantage to making it thinner.

I've been using a setback of 5mm; it doesn't look as elegant as 3mm, but what's elegant about a bridge with the front broken out? I also angle the saddle back by 9 degrees. This reduces the tipping force on it, which helps a lot. It also more or less automatically adjusts the compensation if you raise or lower the saddle to change the action height.

I wish that all luthiers followed the practice of angling the saddle back for the reasons mentioned above.
