Sliding bevels are normally set once for a specific angle, the splay of a leg for example, and then left set for the duration of the project. In that context the screwdriver lock sliding bevel has some key advantages:
It is easier to get a really firm setting with a screwdriver, you don't need to give it the white knuckle death grip, but something just a little stronger than finger tight.
Because the screw is flush with the surface you can use it any way around without having to think about it.Because you need to get a screwdriver out to adjust it, there is less likelihood of inadvertently using it for another job and changing the setting; a bit of masking tape with "workshop stool leg splay angle" written on it is also a good idea.
Sliding bevels are an indispensable tool for recording, storing and transferring angles from drawings to workpieces and from one component to another. Used as a T, Y or an L shape sliding bevels are versatile and adaptable to the situation at hand.
