Leon,

He may be trying to cut way too much log for the blade and saw.

Last fall I ripped a well dried 6"x8" beam into boards with a 1/2"
Timberwolf blade. I eventually got several usable boards from it, but
had lots of problems with the blade bowing in the wood. I was cutting
very slowly too, so I doubt the feed rate was an issue.

The key word there is a well dried beam. Your log might be wet in
spots.

The bowing problem occurs with wood that has been drying for 50+ years as
well as fresh green logs. So I don't think it is an issue with the material
I am cutting.
