Lest you think I am content with sloppy workmanship and will settle for jankiness in my life, let me update you all. I just bought a nice Makita 6″ cordless circular saw so I can now cut straight lines, more or less.
While I could probably benefit from a long straight edge to measure rip cuts for trim, I settled for a thin piece of Baltic Birch to draw my lines (I can’t cut all the jank from my life).
But I will not sit still for that rough edge and cavernous gap surrounding my kitchen formica. I invested in some caulk specially matched and tinted to “Laquered linen”‘. Not perfect, but OK.
