Blade selection
« on: April 19, 2010, 10:55:36 AM »
What is the best 1.25" Wood-Mizer band for sawing White Spruce on an LT40 with a 24hp motor?

Using the 10° band with 22-24 set ain't working very well, I get wavy lumber.
Even with a fresh band.  Running fast or slow.

I'm currently cutting spruce for a customer, and having some problems with wavy cuts as well.  I'm using new DoubleHard 1.25" 9 blades.  I don't have a setter, so the set is whatever they put in at the WM factory.

I think being generous with the lube helps.  I'm using water with a cup of Pine-Sol per 5 gallons.  I'm also learning to pay closer attention to the tension gauge.

The thought had gone through my head that maybe I should try 10 blades instead, but I guess that wouldn't help.  :)

Had a major problem with Norway spruce and got some 7 * blades , .055 1-1/4 had set of .028 to .030.from WM.
worked better but still had some wavy lumber.
Logs were 20" plus.

I love cutting spruce, it is my most favorite wood.  However, it is Sitka Spruce here.

Good reference, I am guess you are not cutting white spruce unless you are in Alaska or Canada.

Well, we're not in Canada, but almost!
We're about 35 miles from Canada in the upper-most part of New York.
There is a lot of White Spruce here, and the best of it was hand-planted in the 30's & 40's.
There are some scattered wild White Spruce, here and there.

Looks like I need a 7 blade to make a decent cut, I think I'll stick with the 1x.045-158 WM blade on the LT40.
