Eric, glad the trespassers did not cause damage. Glad it was only air guns. I guess they would have to go to a shooting range to shoot? Or their own land?
txdon said, "Most older windmill's manuals require oil change out once a year. They have been doing the yearly maintenance long before I got here."
I don't recall our windmill ever having an oil change. You don't suppose my memories from 65 years ago could be fading, do you? I do seem to recall it sometimes getting to "squealing?" and I had to turn it off and get up there with a little oil squirt bottle to oil it. But I suppose that memory could be a bit wrong, too.
I found this study interesting.Feeling OK...bit stuffy...
This COPD isn't going to get better...best can be done is control it. I'll be going to the doctor's this week and there are inhalers that help (wife's been on inhalers since her heart valve replacement...they're used as needed, not constantly).
