Well like i said before i picked up a used portable saw mill.

Issues
I cut a 4 foot red oak log say 18 inch dia cut great was able to cut 1/4 inch thick boards.
Same tree but log was up around 22 and way wetter, Saw cut wavy. UP and down.
Tried pushing slower max speed on blade rpm. Did not get good results.

The only differences was the dia and the bigger log seamed greener and wetter.

I learned to check
The blade tension
The blade guides
I also read possibly the blades “set” is to wide. I don’t know a way to change this but by replacing the blade.

Any one seen this or have this experience?

I have heard that a wavy cut is sign of a dull blade.

-- I intended to be a woodworker, but turned into a tool and lumber collector.

+1 on both of the above. A dull blade will definitely wander… Wavy cut. It is also affected by which blade you’re using. Tooth rake is important. Aggressive rake for soft woods, less steep tooth angle (rake) for hard or highly figured woods. I’m also on the forestry forum and have learned a lot there.

Have your say...
