Undermount sink cutout
We are putting in Butcher block counter tops - and the ones we purchased are just the counter, where we have to cut the sink opening. We are installing an undermount - it is a rectangular sink w/ rounded corners. What would be the best way to cut this opening out? We will only get one chance - and can't afford a mistake. I thought about a skill saw to cut the straight part of the cutout, and then jig saw the curves. Or would a Router be a better choice to cut this out? and if so how would I make a jig for this. thanks.
