I am installing new butcher block-style counters in my kitchen. The new sink has a flat flange around the edge. (It is made to work as as undermount or a drop-in.)
I want to drop in the sink. Ideally, I'd like the top of the sink flange to be flush with the top of the counter. I'm wondering what is the most precise way to shave 1/16" (or less) of the countertop down.
I figured I would drop the sink in its cutout, then use a utility knife to trace around the flange. Then remove the sink, and shave down the counter between the scribe mark and cutout. Any tips on how to remove just a tiny amount of countertop?
A router seems like more tool than you want in this situation, but maybe it could be adjusted to make such a shallow cut?
A chisel seems like it would be hard to control for such a shallow cut.
Do I want to use a hand plane along my knife edge?
Background: My butcher block is from IKEA. It has a beautiful walnut herring bone pattern. Over particle board. The veneer is plenty thick, and my kitchen sees more microwaving than baking from scratch, so I think it will last just fine. But under-mounting the sink isn't an option.
