Hi guys,
Almost done setting up my new Laguna 14 Twelve.
I am 99% sure all settings are good. Using a 3/4 blade from Infinity.
Fence seems properly aligned with the blade…
But when I cut (just a 3/4 baltic birch piece) against the fence, the blade moves left and I get a curved line…
I tried to tweak the alignement go the fence… but I get roughly the same result.

Any idea?

Thanks!!

Watch that. You also may not be tensioning the blade enough. 3/4” Blade is a bit much for a 14” saw.

on Laguna’s web site they have a bunch of videos on the 14/12 look at the one that is about setting the drift angle that could be your problem

Thanks. I did check all the videos already. What’s funny is that Alex Snodgrass swears that drift doesn’t exist…
I have emailed Laguna.

I don’t fully buy into Snodgrass philosophy (I set my wheels to be coplanar) but I do agree that a properly set up band saw should not have drift. Check to make sure your band saw wheels are balanced. I use the sharpie method to see if there is a heavy spot and then balance the wheels using golf club lead tape to balance the wheels. You can also drill out material on heavy side or use wire on the light side but the lead tape works for me as I don’t like drilling wheels!. Make sure the table is square to the blade in both the front to back. Set the blade guides as close as possible but you don’t want the spinning blade to touch the guides. Set the thrust bearings close but also not touching the blade when blade is spinning. Square the fence to the blade. Then with a sharp unkinked blade you should be able to resaw or rip without noticeable drift.

Thanks guys.
I knew about this video.
I now my blade worked well before I changed the tires over the week-end.

Thanks ElChe – much appreciated.
My wheels are “computer balanced” – and I saw the same blade cutting straight a few days ago.
All my guides are 100% good.
I will recheck everything one more time.

I guess I should see the same problem with any blade size?

Will keep you posted!

Give Laguna a call. Their support guys are top notch, and they really know the 14|12. I had some problems with this on my 14|12 and ended up swapping blades and the problem went away instantly and has not reappeared since. I have had great luck with the Resaw Master as well as a 1/2” 3TPI Timberwolf blade. The 14|12 resaws like a dream with either of these blades, with no fuss whatsoever in my experience.

This might sound absurd but feed rate? Everything else seems perfect but feeding too fast could cause the teeth to swerve as they try to move around a buildup of sawdust in the gullet that couldn’t escape the cut. I also think that blade tension could be an issue. The only way I know my blade is tight enough is by spronging it. If it makes a nice tight SPRONG when plucked I’m just about there.

I don’t suppose you got a recommendation for blade tension with the blade or the company website? If not Google BS flutter test. A loose/lax band can cause the band to swerve, a band with one or more thrust bearings set too far back or too far forward can also cause drift. Any of or a combination of both can cause chaos.

Hi,
Thanks for chiming in.
I tried everything (but the kitchen sink…).
Feed rate is not the issue. Tension is perfect.
Just doing test cuts with 3/4 baltic birch.
I will try with a 1/4 inch blade tomorrow.
I even tried playing with the fence – wether its “too much in or too much out”, the blade goes left and the piece leaves the fence…. pic attached

As long as your blade is good and tensioned properly and your guides are set right, you just need to dial in your blade tracking.. that is what it’s there for.. lot’s of folks think it’s only to position the blade on the wheel.. it’s not. A properly adjusted bandsaw has no drift and you should never need to tweak the fence to ‘compensate’ for it.

Cheers,
Brad

My tracking is fine…
The blade is at the same position on both wheels as per Laguna.
I also tried having the gullets in the center as Alex Snodgrass recommends.

Where are you teeth on the tire? Do they ride over the middle of the crest, in front, or behind it?

Well… I tried Alex Snodgrass technique of setting up the back of gullet on the center…. did not help

The tech at Laguna told me to adjust tracking so the blade would run on the same place on both tires

I will talk with them again today

Thanks a lot for chiming in. The saws cuts like a dream. Can’t wait to get a straight cut….
