Moose skulls are difficult to boil and clean primarily due to the angle in which the antler bases diverge from the skull. Containers used to boil a moose skull can be quite large in order to immerse the entire skull and in doing so, at least portion of one antler. This large container can hold up to 45 gallons of water and is difficult to heat the water to the boiling point. The grease in the water can discolor the antler surface at the waterline.
Several years ago, I came up with the idea to design and build a special moose skull boiler that could also be used for elk and caribou. During the design phase of this project, a prototype was made using ¾-inch plywood for the base and cardboard for the sides. Several large Alaska-Yukon moose skulls were fitted into the cardboard/plywood prototype and alterations were made where necessary.
