Cut my first ash tree yesterday and had the worst blade wandering ever. As soon as it got close to a knot the blade dove. New woodmizer blade 7/8 pitch probably 10 degree (changed it twice just to make sure). Tried creeping very very slow. using diesel/ oil mixture for lube.
Cant make happy customers but no idea what to do to minimize.

I use a Simonds 1 1/4 .042 3/4 pitch 4 degree with real good results in white ash. 1/4" down pressure is important. I also have used Simonds 1 1/4 .042 7/8 pitch 10 degree which cut good also but get dull quicker. If those are WM Silvertip good luck, the last box of 10 I tried I took them back, never used WM double hard. With white ash on wide cuts I feed a little slower than normal but still at a good rate.

Also I don't run 1 1/2" blades but have heard reports they don't cut frozen wood very well. Steve

Sharp DoubleHard WM blades (10 degree) is what I use and have not had any problems with Ash, knots or otherwise. Are you cutting from the bottom up on the log or from top down?
I have read, but not experienced it, cutting from the top down (small end to large end) can lead to that problem.

ash is a drier wood ,use more lube to keep your blade cooler but, not to much. the drier sawdust will actually expand with the water making the blade's rakers want to ride up or down because it can't remove the sawdust. i use 1-1/2 x.055 7/39 year around .they work really well in frozen wood.

i won't /don't use woodmizer blades, definitely not worth the money >:( i use kasco blades and resharpen them to 7/39. they last on average 2 sharpenings longer and cost about $20 less per blade
