Huge Pine Knots! How Does a Woodmizer LT15 Handle them? Wavy Cuts? 

I sharpened industrial bandsaw blades for a mill. We call the wavy cuts "snaking." Also, I've seen frozen southern yellow pine knots damage saw teeth so badly that I had to change blades.

I feel your pain. Bring someone over to see and its perfect!!! LOL

Would like to have had that log cut into 3inch slabs stickered somewhere for some woodworking projects in a couple of years.

deer around here act like I’m trespassing whenever I’m leaving in my car! They look slightly peeved!😀 Great video. Thanks

😁😁😁😁😁😁 watch your band leaving the log, it will tell you everything you need to know about your band life

Look like you got everything adjusted before you started milling, fine job 👍

Its Okay that you didn't screw up 🤣🤣

Those branch swells would make interesting bowls.

Don’t you just love it when you try to demo a problem and and the demo works faultlessly.. lol I found out if I cut my pine logs as soon as I get them real fresh and green green I don’t have much problems with the knots but if I let them dry out on me I will often get wavy cuts. Hey it’s nice to share with your neighbors… good video, but the next time you want to do a problem demo video . Don’t plan on it…. lol take care

Even though you're a liar, I hit the "Like" button anyway. Speaking of wavy cuts, what I recently found out from Wood-Mizer to reduce wavy cuts are these suggestions; 1. Mill a log from the small end. Apparently the angle of the limb growth rings can cause blade deflection. 2. Make sure that your drive belt is correctly tensioned. A loose belt can also cause deflection due to slipping. 3. Use a sharp blade. Obviously. 4. Blade hook angle can be 10 degree (for all-around milling) or 7 degree (for hardwoods but they say it'll work just fine on softwoods). I use Turbo-7s (7 degree hook and 39 degree back angles) and find that they are very aggressive and tend to leave chatter marks on the lumber. WM also recommends something like 25HP as the minimum HP for these blades. I recently used a 10 degree blade on some pine and the finish was very smooth with very little sawdust left on the board. 5. This is the surprising part; on my LT40 they recommended I increase the blade tension from 2800PSI to 3400PSI. They say that the newer blades are stronger and can take the extra tension. I don't know how to translate the numbers to the LT15 but I recommend you check with your local WB tech support person to confirm that this is correct. Good luck, Dave

Are you cutting those knotty pines from small end first heard might help with knotty wood definitely sharp blade

Well done Brother! Nathan at Out Of The Woods says speed has a lot to do with it, in addition to tension and blade quality that You mentioned! He has to slow down even on his Super 70!

We've had good luck with 4 degree blades on our Lt15 for knotty pine and/or hardwoods (work well on frozen logs too).

Does knot seam to be a problem.😊

You're not a liar, the mill just decided to play head games with you. (Now you know why I curse and cajole my tools and machines as I work...) I too experience wavy cuts on my Timbery M100 (220v 5hp) mill, and it's nearly always due to age of blade/sharpness and/or blade tension. Rarely, it has been due to 'gummy-blade' from the buildup of Ponderosa pine pitch on the blades. It took me most of the video, but I finally figured out what your angle was around the 9:00 minute mark; you're using reverse psychology on the LT15 to make it think you wanted wavy cuts... So, like a teenager, (or every officer I dealt within the Army) it does the opposite. Very clever, well done! Your workmates who want the damp/cool sawdust are getting used to your presence; I have one doe who enacts a casual grazing pattern as I work in my forest; I call her Jane, (as in "Jane-doe") she has even brought her newest fawn for a walk past/viewing; waaay cool. Just some random musings from your neighbor to the North, in Linn County.

Do you feed those deer or do they just hang around for the bedding, your company, or the good smells? Cool.

I love the full wraps!!nice broom lol cuts look good 👍 Have them on almost all my bigger saws

Maybe these knots just arent as dense as past trouble knots were?

What does your manual say about log size vers you koler horse power??

I just realized why YOU get wavy cuts. It's because you pull a "Dave".
