6:02 ok so with drilling the holes i used to have trouble but the most perfect perfect way that is right every time, you just mark the exact position with a ruler and then with a small drill bit (FOR WOOD) with the little guide spike on the tip, drill a tiny guide hole. Then you need a step drill bit which gradually gets bigger like a cone shape. Use this bit then to get perfect hole sizes. Do not just use this drill bit or any drill bit that has a rounded tip, they can move slightly. Use the wood drill bits with the pointed tip and then the step bit to make the actual hole. hope this helps!
