Of course, now we do not want to cut into the nice, pristine, virginal surface, do we? Since the track hinge positions the track for a repeatable saw cut, what is needed is a replaceable insert for a saw kerf. The plan was to make this with a sliding dovetail. This could be left loose and removable, yet be solidly attached.

The track and saw are used to kerf the outside of the insert. This is 1/2" deep ..

I had made two inserts (one a spare), and these were doubled up to create an angle guide for a chisel. The dovetail was created this way ...

And, finally, a board was sawn using the track, leaving a fine kerf in the new insert ...
