[QUOTE="Nightjar, post: 65549, member: 1414"] Golddigg, Maybe something you can try. At the moment it appears you have a direct blast of air into the box and a counterweight for vibration. What you need is interrupted air supply, eg: bellows type dry blower is interrupted. Before you spend more money it would be worth your while experimenting with making your air supply "flutter." ie: Difficult to explain, but here goes. Cut a round metal disc to the inside diameter of the blower delivery, curve the ends so the blown air will make it spin on a shaft. Drill holes through the pipe slide a rod through then tack weld it to the disc. When the blower delivers air it will flutter with the spinning disc and help move your fines down the riffle box. Maybe someone here can draw a diagram to explain it clearly. [/QUOTE]
