LEE Said> Perfect Powder Measure Leakage
Posted by on 20 October 2011 04:01 PM
To eliminate leakage, disassemble the measure and clean thoroughly. Dust with powdered graphite or mica, and re-assemble. Powdered graphite is available at most hardware stores (often used as a dry lubricant for locks). Work the lever back and forth to spread the powdered lubricant over the mating surfaces. Disassemble and observe the wear pattern on the cone shaped mating surface between the metering chamber and body. There should be even wear across the whole surface. If not, dust with lube and try again, with the tension screw slightly tighter (or looser, depending on the appearance). If you can't get an even wear pattern return the measure to the factory for repair/replacement.

To get the proper tension on the screw that holds the rotor assembly to the base, place the lever in the up position and tighten the screw until you cannot move the lever up and down. With an empty powder measure, begin loosening the screw until the lever begins to move downward. Once this occurs, you have achieved the correct tension.

Cast iron and aluminum parts need to be lubricated, and cast iron is susceptible to rust.

The lubrication is the graphite on the powder put there for flow in manufacturing and to limit charging from movement and static electricity.
The powder conducts well enough the grains cannot have different charges.

Unless the plastic is loaded with carbon or another conductor it can trap a static charge on the surface.

Keep the powder measures in at least a box with some VCI chips.

I have guns, reloading dies and equipment, a mill, lathes (wood and metal) table saw, bandsaw, jig saw, 8 inch jointer, 18 inch thickness planer, taps, dies, power mortiser, grinders, and racks and drawers of other tools.

They ALL can corrode without protection.

Every drawer and container has VCI chips.

No corrosion even after a few inches of water in the basement from a collapsed main sewer line.

I do not lube my Redding measures anymore. They don't need it.
