Hello, I’ve been resawing a lot of 3×5 white cedar recently. It’s very old …. DRY.

I have a highland woodworking wood slicer 3/4” x 3-4 TPI blade.

In my unprofessional opinion it’s just not cutting fast enough. The blade is fairly new. I’d estimate it takes me 3 minutes to rip an 8 footer.

Is that normal?

I thought I wanted a 1-2 TPI blade and wider but I discovered that highland doesn’t go wider or lower TPI which made me question my thinking. My saw is an OLD Grizzly 18”. Forget the HP. Nothing crazy.

Would appreciate your thoughts!

todd, That cedar should be pretty soft and easy to saw. I put a 1”, 1 TPI Timberwolf band on my 17” Grizzly and it will resaw 10” Jatoba (really hard) as fast as I can feed it! It’s almost scary as there is almost no pushing required. I also have a 2-3 variable TPI 3/4” bimetallic band from Timberwolf that saws almost as fast and leaves an amazing finish. Timberwolf is really good about advising you as to the best blade for your application. Call their 800 number and ask questions.

Wood slicer from Highland is a good blade, but with an 18” saw I’d go to a 1” blade with lower tooth count as gfadvm suggested.
Also, blades get dull pretty fast sometimes; depending on what they have been cutting more than how much. I have dulled a new blade on one board. It’s possible.

Thanks guys.

I really want to experiment with a wider blade. I’ll order one.

I think you’re probably right about mine getting dull. I wouldn’t think my cedar would have much tension in it, but it was actually binding. It got to the point where I had to split it on the output side or it would bind the blade and stop it from spinning. Maybe that’s just because the blade got dull?

Do you sharpen your own blades?

I can’t figure out why the blades on my sawmill last SO much longer than the ones on my bandsaw. And when they get dull, I send them in and they get resharpened/reset for $7 each! And they cost less than half what the bandsaw blades cost!

I wonder if more horsepower actually eases wear on blades.

Any thoughts?

I recently did a bunch of resawing and could tell on exactly what “cut” my lower thrust bearing locked up (failed). When the thrust bearing failed, the feed rate dropped to probably 25% of what it was. The cut was still straight, but had to push much harder without any other feedback from my 14in Rikon 10-325 BS.

Just a thought. Bearings are cheap, if you shop wisely. And they are very easy to replace.

Here’s a link to Woodgears guy – who sharpens his own.

I have to ask, have you been cutting wood with bark on it?

Bark dulls blades fast. I used to saw raw logs w/o removing the bark.
I was never happy.

On a chance I started taking the bark off. I was now able to saw longer, and faster.
I use the same blade for resawing. And I noticed a huge difference in resawing. So I was killing my blades when I was sawing logs.

Jeff, Almost all the logs I saw on the sawmill have the bark on. Doesn’t seem to be a problem unless it has dirt/mud/gravel in it.
