All the pegs and all the holes that we sell are made from the same wood by the same machines, in order to make them fit tightly.
The peg has to be installed using a strong man (male) force. It mast be strongly fit in order to hold falling from the didgeridoo weight.
Please place the base on the floor, stand on it with both your legs, then place peg directly on the hole in an exact vertical position, hold it with both hands, and using your body weight, push the peg inside the hole, while twisting the peg a bit to the left and to right while pushing.
