I just got a new, used 98 LT40 super with 40 hp Lombardini engine and am not familiar with what type of blade to use. I want to sharpen and set my own, so not sure if the .055, the thick 1 1/4", is difficult to set and take care of? I think this is the blade Wood-Mizer recommends for the horsepower I have. Any experience with what performs well? I was using an electric 15 hp LT40 and buying 10 degree blades, standard hardwood type, and grinding some of them back to 7 degree for our super hard logs, like stone dead ash and hard maple that I get from tree service guys. This allowed me to saw and sharpen with two different blades, but take care of them without switching cams and whatnot on the sharpener. I don't want too many profiles to monkey with. Is the new 7 degree something to consider?

From contributor M:
I have the exact sawmill that you have. A lot depends on the species that you will mainly saw. I saw predominately SYP with a bit of hardwood thrown in. I use 10 degree blades and use the WM ReSharp service. I know a sawyer that saws predominantly oak and uses 7 degree blades. We are both satisfied with our blade performance.
We have an LT40 Super with 25 hp electric motor. We saw mostly oak. Sometimes the logs dry before we can get to them. Frozen in winter. We have standardized on Wood-Mizer DoubleHards .045 x 1.25 with 7 degree tooth profile. As contributor A said, the .045s will give more sawing life than the .055s. But the .055s are real nice when sawing the big logs.
We got the WM CBN sharpener and setter last year and Iíve been sharpening our blades. Itís amazing how many re-sharps I have gotten out of the .045 blades. Probably way more than practical.
