I have an old block plane and LA block I'm going to clean up. Could someone tell me what angle to grind the bevels to?
Thx,

Block plane irons are typically ground at 25*, I believe.

Since a block plane is a bevel up plane, you have the option of a wide range of bevel angles, each one of which is used for a different purpose. It is a really good idea to invest in one or two extra blades for your block plane.
Assuming that you have a low angle block plane (not a standard angle), the bed is 12 degrees (the standard version is 20 degrees).
For end grain, use a 25 degree bevel (= cutting angle of 37 degrees).
For face grain on medium density, uncomplicated timber, use a 35 degree bevel (= cutting angle of 47 degrees).
As a mini-smoother of difficult face grain, use a 50 degree bevel (= cutting angle of 62 degrees).
