    I picked up a Chromega 8x10 print drum recently. My Unicolor drum started to leak, and I hear the Chromegas are better built and use less chemistry. As it goes, the Chromega drum I got does in fact have a small leak. It's on the bottom cap and, strangely, it's not even at a seam. It seems to be leaking through the plastic itself. Is there an easy fix for this -- caulk or something?

    Also, the Chromega drum has this centering ring which I'm unsure about. It seems to be used to keep it centered on the Chromega agitator. I wonder if I can use the drum, sans centering ring, on my Unicolor motor base. Or is there something magic about the Chromega agitator and centering ring that enables the magic "sine_wave action" that they tout?

    Thanks.

    Good Evening, bvy,

    Neither of my Chromega drums has a centering ring; that's no particular problem as long as the motor base is level.

    As far as I know, the plastic used for Chromega drums is softened by the common acetone-type cement used for constructing models. If you can locate the spot of the leak, it should be simple to "melt" the plastic back together or to patch it with a small bit of similar plastic. If the bad spot is indeed on the cap, the repair could be either internal or external without affecting functionality at all.

    Thanks. Good idea. The previous owner conveniently drew arrows pointing to the leak, and it looks like it's even been patched up before.

    The sine wave action comes from the fact that the wheels on the agitator are not centered, so the drums rock back and forth as they rotate, causing the liquid inside to move left and right while the drum is turning.
