Wooden Christmas tree with colour-changing lights

Step 5 Drill the holes

Here you can see my assistant drilling the holes. Note how he is holding the wood firmly to the bench, with his hand well away from the power-drill. We don't want any red colour where we want green.

Note also that he's taking care not to drill a hole in Daddy's bench.

It's best to drill from the side that you want to be the front (if it matters which side is which), because the drill tends to snap out of the back and make a less tidy hole on the other side.

Depending how thick your MDF is, you may find it drills easier if you keep lifting the drill out as you drill, to clear the MDF "dust" from the drill bit.
