LEE pro auto disc leaking powder (fixed w/pics)

OK, so I'm having a situation where my pro auto disc powder dispenser is spilling some powder. I took the unit completely apart and I can't see anything obviously wrong. I do have about 1/16" of free slop in the discs and I don't know if the discs are supposed to be sealed against the body or not. Those of you that have the double disc kit is there any play in the discs ? I can also see light between the top cover the to top of the disc so this is obviously where the powder is leaking out. There is a rubber sealing ring that is not contacting the top disc and I'm wondering if this is my problem ?

I would assume that the "elastomer wiper" not contacting the disk is your problem. I use the double disk when loading AR fodder and do not have a gap between the wiper and disks. I do have about a 1/16" play front to back as well. Seems as that's the norm with the disks.
 
Over time the wiper may degrade a bit, causing leaking. Mine is doing that right now especially with powdersl like AA 7, which is more like dust.

I keep meaning to try making a gasket or two out of various materials (paper, thick paper, plastic) to see if that cures the issue. If not, I'll try replacing the wiper.
 
Road Clam,

I get some "leakage" with mine also, I got the upgrade kit. Seems to really only do it with my Ramshot True Blue, and other really small grain ball powders. Some of which really are like powder... :rolleyes:
 
Wild Willy, that's exactly the mod I was thinking of. I also might take the base and mill about .010" off the top rails. This will basically achieve the same outcome as sanding down the risers. I think if I can get the disc to contact the rubber wiper i'll be all set. My base machining mod will also work if I only want to use a single disc setup for pistol charging.
