You will also need a forstner bit to drill out the recesses for the tea lights. My electric tea lights were 1.5 inches in diameter so that is the size bit I used. If you chose a different size candle make sure to change the bit size. Forstner bits are not cheap but they come in very handy if you can pick some up. You can buy them individually or in sets.
If you don't have a forstner bit then just use 1/2" thick wood and cut the holes with your saw. The tea light will still stand proud of the top and look fine.
