I'm building a bartop out of 1/2" mdo. I have enough 3/4" t-molding to cover it and I'm trying to avoid spending any money at the moment. I cut a slot in a scrap piece of 1/2" and tried to shave down the t-molding to 1/2" with a utility knife. It turned out okay but not great. Any tips or tools I could use to get better results?
