Weather has keep me from the mill till yesterday I was able to tighten belt and band tension and noticed no difference. I may have titled this post wrong my cuts are true I am getting teeth marks in the lumber I am cutting. So the cuts are straight and dimension is true, I may need to switch to a lower degree blade. I also think i need to lube my rails more I blow off the mill frequently throughout the day and spray silicon lubricant along moving parts and the rail. I am using the mill to remove maple trees through out my property to improve for wildlife. Everywhere there is a stump from the last time the property was logged 2 or 3 maples grew in that opening.

Woodmizer sells a variety box with 6 blades 747, 4 degree and 9 degree. I think ill try them my cousin has a red oak we were thinking of sawing into trailer decking. I know that red oak will need a better band then what i have.

 Those marks usually mean you have knocked the set out on the blade. Are you sure you haven't hit your back stops? Try a new blade. If the blade is still cutting good save it for lumber that it doesn't matter on.

Woodmizer says not to run anything on the LT15 except 4 degree.  The 19HP engine isn't enough power to run any higher degree band.

I don't use any silicone based products.  If it gets on anything, including wood, it will create problems with any finish applied.  Body shops will not allow any silicone based products in their shops because it wreaks havoc with paint/primer.  Tire shine that contains silcone is a bad thing as it will get on the paint and if it ever needs bodywork/paintwork, it is extremely difficult to get off.  Just when you think you have it, you spray and the paint or primer beads like water on oil.  Arggggg!

Why would you have lubricant on mill rails- as rollers don't need lube on rails?  Is it to keep sawdust from sticking to it?  I don't usually have that problem with hardwoods.  I do wax my cross bars with Johnson Paste wax to help logs slide better so make manually turning them easier.
Anything someone can design, I can sure figure out how to fix!
If I say it\\\\\\\'s going to take so long, multiply that by at least 3!

Yeah the spray was what I had the idea of lube was for clean up and just a smoother operation. I spoke with a guy west of where I live he ran a Norwood and said he cut everything with a 10 degree. Timbery doesn’t sell a 4 on there site the variety pack I spoke of earlier is kinda pricey with shipping, but I’d like to try a few blades before buying a 10 pack. I want some 4 degree blades so I can cut a little hardwood.

Good Pics! 8)

I will be interested to hear your results with 4 degree bands if you get some. I am milling with a 15 horse engine and 10 degree bands. It feels like my mill struggles with wide cuts but I haven't thrown down the money for some 7 or 4 degrees yet.

Grab a few 2x10s from Depot, put on the mill and check everything is level.

Then try and cut the 2x10’s down and inch and see how uniform it is.  If this test passes then you can move to wood type, belt tension, etc.

Send some pics of the wavy wood and run your test with a new blade.

Good luck

If you are getting chatter all along the board then yes a tooth or teeth have been dinged or knocked out of set.

If the chatter starts and stops then that is often a sign of not enough feed speed. Which can be due to wrong tooth angle for the wood being cut, dull band not allowing adequate feed speed, or just not enough feed speed.

Here's a good suggestion that I remember hearing way back when I first got my mill:

When things are not quite right with your mill, "make only one change/adjustment at a time"!

If you change a few things at the same time and the issue gets fixed, you don't really know which one of those cured the problem!

Just sayin'!

Try 7° in softwood and 4° in hardwood your cuts will be nice and smooth

 I had a good day of sawing today tightening the blade tension took the chatter out of the saw head. I Snugged the drive belt a little but that was just a minor adjustment. I haven’t been able to order new blades yet but when I do I’ll give an update. The lumber turned out really well over 300 bdft for a friend. Maple siding for the inside of his shop he was very happy and I was glad to repay him for some help he has given me.
