the size of the final hole you want to end up with (about 33-40 mm across). Discard any extra beeswax you might have and join the ends of the beeswax. Now work around the mouthpiece pressing the beeswax firmly onto the top surface of the didgeridoo, keeping an eye on getting an even circle and that the wax tapers out nicely and does not get too thin on the top surface of the didgeridoo. On the next round seal the beeswax firmly against the inside of the didgeridoo, letting it taper out evenly into the didgeridoo. Then adjust the heights level of the mouthpiece and the inside diameter. You want to form a fairly sharp edge which allows your lips to vibrate freely, rather than a rounded edge which will make that harder.
