Spent the day yesterday troubleshooting and doing maintenance on the mill. There are so many little nuances that can effect performance and I am learning them the hard way. Something that appears so simple can develop into an engine that needs tuning, or a child that needs discipline. Big issues like a log that has pulled away from a dog or a governor that is not kicking in are obvious. Others that can sneak in or come on in multiples, not so much. Yesterday was one of those that test and educate at the same time. What started off Saturday as a log that stopped rolling (the knife had come out of the kerf) became a plague which started with a band aid. To make a long story short, several adjustments to the knife placed it back in the grove but the carriage refused to return without slipping belts. There are many reasons why belts will slip and apparently I had not thought of them all. After going through everything else, and before I adjusted the main mandrel on the carriage return, I found both the idler pulleys had sized up from dry grease, and the mandrel needed adjustment too. Once I began cutting again everything ran true for a cut or two then the saw began tracking away from the log. I popped it back and allowed it to cool, but not before thinking I had another slippage problem or the blade needed sharpening. None of those were the problem. It turns out one of the pucks that keep the smaller flexes in line before the blade is stabilized in the log had worn enough to look adjusted but not fall out, after being worn out to the max. Every time I seated it, I would get one cut straight then the next would drift. It finally fell out. It was almost dark, I had only two cuts left, so I made a new puck and ran a correction cut. The last two boards were perfect. The blade has been sharpened. The belts are fine tuned and everything is greased. Not like once you get your car humming you can go for miles without an issue. More like a Model A Ford. It'll run like a Watch until it doesn't. Only the symptoms are different, as is the learning curve. The power plant is a separate issue. As with life, it's only fun when you are not sick, the weather is nice, and your bowels are moving!
