3 Hold Wax: Hopper Designed to hold an entire bag of wax flakes Reduces operator work during operation Hopper held within base with springs to reduce affects of vibrations from vibrator For drawings see attached

4 Transport Wax: Chute Goal: Transport 2 gallons of wax at a time into the tank Wax flow controlled by a door operator by a linear actuator Ideal chute angle to transport wax flakes: 45° Vibrator is attached to the backside of chute to improve transfer Super-Quiet Low-Impact Electric Vibrator Nonadjustable Force, 115 VAC, 1.4 Amps, 25 lbs Force http://www.mcmaster.com/#catalog/119/517/=lsgnla

5 Melt Wax: Melting Tank Goal: Melt 2 gallon batch of wax within 10 minutes Aluminum tank structure heaters around exterior wall of tank is sole provider of heat to melt the wax Aluminum shaft and 2 stirrers induce flow and increase melt rate Insulation surrounding tank prevent heat loss to surroundings
