Were not ready quiet yet to drill the holes. There’s one more thing we
need to know that we’ve not talked about. Can you guess what it is? We
don’t know how deep to drill our holes! If we drill holes all the way
through the pegs will fall out the bottom, but if we don’t drill deep
enough the pegs won’t hold and they’ll fall over. Well, we did some
experimenting with our peg games and found that we needed to drill
about a ½” deep hole into our ¾” board in order for the pegs to fit
snuggly. Here’s a trick to make sure all your holes turn out to be a ½”
deep. Lay your bit across the depth of the board and measure down ½”.
Wrap a piece of tape around the bit where the bit hits the top of the
board. Stop drilling when the piece of tape reaches the top of the hole.

Drill your holes and check the fit with the pegs you’ve chosen. Are all
the tops of the pegs the same height? If not you may have to go back
and check to make sure all the holes are drilled to the correct depth.
