Panel height

[577SXS]

I always have an issue getting the panel height right after inletting the lock. I usually leave extra wood because I don't want to mess up. The lock plate bevel ends up being below the wood and I know it should be level with it. OK I had an idea and I think its going to work perfect. I cut out a piece of 1/16" thick steel the shape of the lock plate. Really didn't take very long. I cut a notch where bolster was and clamped the lock plate to my sheet. I then scribed around it and cut it out. Now to get lock panel the right height I can set this plate into mortise and file flush to plate. Maybe this should be under Shop Made Tools.

Nice idea for sure, BUT just don’t see a need for it.  Just  takes a couple of file and try attempts, and it’s done.
Actually, I just use a belt sander belt, attached to a piece of 2x4 to keep it flat, and sand away.
If it works for you.......use it!

You know what the thickness of the lock bolster is. and you can determine the thickness of the lock plate bevel. Before you start inletting the lock get you panel thickness close to what the finish dimension is going to be.
It is easier to screw up the deeper you have to sink the plate into the wood. Don't need more than .015 extra wood.
