I ripped a 1" piece off a 17" piece of 4/4 hard maple. Looking at the
offcut, there were burn marks on the left side ( the 1" offcut ) but the
main piece was as smooth as a whistle. Using a WWII thin kerf blade.
Usually
have no problems. Only thing different is I used one of those Micro
splitters that stick in a zero clearance insert. Altho how it could burn
on
the inside of the free piece is puzzling to me.

Any idea what could cause this. Only thing that occurs to me considering
where the burn marks are is that there were some internal stresses in the
wood that causes the offcut piece to press against the left side of the
blade.

A splitter will help prevent binding and some burning. The blade does in
deed come in contact with both sides of the cut before it reaches the
splitter.

You are pushing the wood too slowly, or the blade is not perfectly clean, or
your fence is toed out on the back right side of the blade.
