Sink Installation Video
Do you want to install a sink in an existing countertop? Tim Carter shows you how to install the sink with these easy to follow tips.
Position the new sink upside down on the countertop and accurately trace the outline of the sink. This provides a guideline for the real mark for the cut-out. The cutout will normally be about 3/16" inside the original mark. This allows for the lip of the sink to overhang the countertop. Check the sink installation directions for the proper measurement. Don't make square corners when cutting out the hole. The corners should have a radius of about 1-1/2". Grab a can out of the pantry to draw your curve.
To make the cut out, two power tools will be needed. A regular drill to drill a starter hole in the counter and a spiral saw to cut the countertop. Drill the starter hole and cut out half of the sink opening with the spiral saw. Screw a board across the opening to hold the cut out piece of countertop from falling down into the cabinet. This board can also be used to lift the piece out of the counter.
The next video, Water Faucet, will show how to install the sink into the opening you just cut and install the water faucet.

I have an undercounter sink installation which is not complete on one side and has (2) 2x4's that are supporting it on the kitchen cabinet floor which needs to be replace after my garbage disposal was leaking. The sink was to have silicone around the top and clamps that would have made it more secure after being left alone for 24 hours. The installer only did a slight row of silicone and no 24 hour set. They were in a hurry to finish and leave. I could do it but I'm not as strong as others. Looking for some help.
