Here you see the Minimoog's Pratt-Read keyboard assembly.  All the keys are now removed.

The rubber key bushings are dried out, cracked, and crumbling off the key stops.

A few deteriorated bushings had been replaced by pieces of spaghetti tubing.

Here you see the exposed key stops after scraping off the old bushings.

The stops aren't all level, especially in the heavy traffic area.

We'll adjust the stop heights after the keys are reinstalled.

Here's the cleaned-up keybed with newly installed rubber bushings.

The bushings were lubricated with Dow Corning^® #7 silicone release compound.

The "V" shaped fins of each bushing go down, as shown here, and the wider trough goes up.
