Yo, Yo' (not the coca-cola type). If I may be rude to make a suggestion for next time.
If you plan to make another or decide to use different kerfed blades or angled/bevel cuts... between the tracks, convert the top 1/2" layer into 2 x 1/4". The bottom 1/4" layer fixed/permanent to the bottom 1/2" and the top layer replaceble. That way you can swap out the top "skin" with whatever kerfed/angled insert... just keep the first/original skin as a drilling template for future skins so that you hit the same screw holes without perforating the bottom layer.
BTW, 👍for the KM stop... I've got a couple and love them.
If your first cut is too short... Take the second cut from the longer end... LBD
