To make this brief, I am trying to replace my kitchen sink. Laminate coutertops, hole is right size but there is no overlap of countertop to attach sink clips.

There is 1/2" thick base cabinet wood walls on either side so I was thinking of routing or chiseling little notches to fit the sink clips and give them something to bite into.

Then I thought an easier way would be to go ahead and silicone the sink in place and then put a 5 gallon bucket of water in each bowl to provide weight and let it sit for 12-24 hours.

Any ideas??
