I tried the straight edge on the fret plane thing, the bottom of the straight edge lines up just under the top to the bridge channel with no bridge in.
I tried the bridge set up that is suggested by stew Mac - this didn’t seem to work well with my kit, using their measurements my bridge would be 20/32 I.e. 5/8 inch high.
Also the bridge is way below the underside of the hand rest of the cover plate, they suggest that the strings should be touching prior to tensioning them.

Trevor do you have any idea of how far you bridge was depressed when the strings were on and in tune? Reading internet stuff some said 1/4 to 1/2 inch depression

This is a whole new ballgame to other guitars
