Here is a photo of the beautiful rainbow we saw arching over the transmitter site when we arrived this morning:My goal for the day was to improve the performance of the PA inductor that I inspected on Friday.  One of two thin shims was removed under one of the idler roller carriers.  The idler rollers now only touched slightly in one spot and the drive shaft of the inductor turned much easier.

This is the shim that was removed resting against the carrier from under which it had been removed.

The plastic splined drive shaft is supposed to move in-and-out freely, but was too tight.  It is supposed to be just tight enough to not allow backlash when changing direction.  Absent a milling machine to slightly widen the slot in the spline, I tried a file, and sandpaper with little success.  Evently, I scraped it with the blade of my pocket knife.  It was a slow, tedious process, but it did the job!

The white plastic drive shaft, at the left bottom of the photo, pulls out about a foot further than seen here and needs to slide easily with no backlash when rotated.

This evening we took a step of faith and purchased air tickets for our month-long trip to Swaziland starting in mid- October.
