DAY OF DISCOVERY
Learned a lot today. Some I fixed, some I still have to fix, some I'll have to learn how to fix, and some I'll have to ignore.
Yesterday the blade came off. Tension adjustment was an issue. I looked at my bar-inside-bar theory with a hammer today. Bar is indeed SUPPOSED
to move within the other for blade tension. Not enough room for a real hammer so I used a claw hammer and beat it like it owed me money.
It moved enough to confirm my theory and loosened, then tightened the blade. It was, and essentially still is seized.

Got the blade back on and turned it all by hand a 1/2 dozen turns. The blades are not tracking evenly.

Loosened all the guides and reset everything. Originally I didn't put the guides against anything; just left them a hair away. They weren't touching anything when I got this thing so I figured leave well enough alone.
Today I set everything the way you-tube has been telling me to.
The horizontal guide bearing looked like it was supposed to keep the blade running in a certain place so I set it to juuuust touch the blade. Blade sits low, but the wear showing is from past use so.....

The blade hits the top cover but it looks like it's been doing that all along and doesn't even leave wear marks.

Late in the day I tried some cutting after all the adjustments and I'm getting some climb of the blade.
These are side views of the boards.

IIRC this is caused by the blade not running flat on the wheel, or guides. Not sure if it's a major issue at the moment because I'm
just needing to cut "landscape" timbers. I was also cutting at full RPM for the first time, and faster feed as I get more familiar and confident.
Using the level as a straight edge......

In the close-up picture of the blade guide, it looks like the blade points are very dull. Also, the blade cover being bent down and the blade rubbing on it will dull the edge of the teeth. The teeth are "set" left and right from the blade to make a slightly wider cut in the wood to prevent binding/friction/heat from the main part of the blade. Dulling one "side" of the blade and the teeth being dull also is likely the cause of the wavy cuts. Straighten out the cover so the blade doesn't rub on it and sharpen/set or get a new blade and you should see improvement in your cuts.
