Before I bought my mobile dimension mill,  I had an Amishman with a band mill saw for me.  I had a few poplar logs that had been cut a while.  He said he would saw them but they would be wavy.  He was right.  But the fresh cut logs sawed nice.

 After sawing 30 red oak, white oak and white ash logs today, got ot ther first poplar at about 2 pm, put on a just sharpened blade that was a little low on the set it dove 1/2" in the first 2 feet, then put a blade with good set that straight for over 2 hours. It's the set.   Steve
