To much set to much sawdust

[Shiny steve]

Hi all, I have been running a woodlands 130max for about 5 years. I have been using ripper 37 1 1/4 blades (sharpened and set myself) although lots of these have now snapped I’m not to stress about this for the amount of used I’ve had from them 

 

I have purchased a new to me used mill (wm lt40). It came with a load of blades, I have just started using some of these on the woodlands as the Woodmizer isn’t set up yet. I have been getting some strange results, they look very coarse set I haven’t measured them yet but the finish is terrible and loads of sawdust is left in the cut. I got fed up with this today and switched back to one of my old blades, problem gone
