3Z107B 3 Cylinder SpeedAire Compressor (part 11) molasses update

I removed the parts from the molasses and cleaned them up.  The procedure was recorded with 2 cameras but there is a lot of video and  and it will take some time to edit it.

The parts were in the molasses for a long time and a crust formed along the top of the parts.  The good news is that it looks like there is no damage from this and a significant amount if not all of the buildup is gone from all but the worst cylinder.  The lesson here is to use a deeper container or rotate the parts every week or so.

The next step is to take the snap gauges and determine which cylinders to use.

Someplace on the web I read that a place which rebuilds compressors honed the cylinders by media blasting.  No details.  The idea is that it prepares the surface to better hold oil.
