I couldn’t get a good camera angle from underneath to show you guys how to cut the wood but basically what happens is, once the wood is cut, the sink is literally going to drop.

Therefore, if we keep it supported from up above, then we can safely lower it down without actually creating any damage even worse, falling on some plumbing pipes and causing a really big issue, so you want to get a really good game plan together What you see here is We are cutting out the corian for the new sink.
