Thread: more curves than a dogs back leg

is that accross the cut or along it?

The last time I saw curves like those the missus slapped me

Being a bandsaw owner Travis, how that was stacked has nothing to do with it. Either it was cut too quick or bad blade setup. Either way, sawyer error in a BIG way. Dont mean to bag anyone via the internet and not in their face but its all i can do from here

Thanks everyone for input and thoughts.

I did think the sawing was not up to scratch and everyone has had a similliar opinion that backs up my thoughts, recieved a positve email back from the mill today, they want to work something out, replace the lost timber the manager was not aware of the bad job done by the sawyer, very apologetic, the sawyer no longer works for the mill anymore and the bandsaw that was used is now retired.

Stickering was not the cause of the curves, timber is too thick over too short a distance, a 1" board, yeh....

Carl, not sure what u are asking, but the pics are of a board/s that I have cut from a slab that I have then turned on its edge, it really makes the blade wander standout.

Well thats not so bad.

Agreed nifty, as a sawdoctor I have a fair understanding of what causes that effect, hence my first comment regarding the saw and the operator.

So PJT is that bandsaw for sale? Please pm the website of the owner.

Looks like it was stickered very badly,has it been seasoned?
Surely (bandsaw owners could tell me) with that amount of 'wave' in the board, if it occurred during cutting the blade would bind and not cut anymore? Relating it back to my Lucas, if the log has shifted after a bit of cutting and ends up with the horizontal face about 5mm high and pushing up under the blade, she bogs down and is 'hard' to push along the rails, you certainly know you need to come back out and resurface that layer to keep going...

I reckon this pic shows what Al is talking about here...

the sawyer at a guess has been pushing and it has resisted as the blade has dived off, I know with mine that it will get to the point it just aint gonna go any further and if u persist u are trying to then trying twist the blade further away from a straight cut.

yes I agree what sigidi is trying to express and what you have encountered with your huon are 2 different things and it is most definetly due to the way it has been sawn. I will get some pics of some blackwood which is very similar but not as bad as what you have there. It is a common thing with bandsaws and is caused by a couple of things including incorrect setting of the blades but most commonly blunt blades.

Hi all i run a forrester mill myself and when i see cutting like that on a forrester it could be a couple of things blade tension,blade guides on machine not adjusted,not the right tooth angle on blade,very blunt blade or pushing it to much trying to cut to fast. mine cuts for about 9 hours a day 6 days a week never had a prob like that doesnt matter what type of wood cut a heap of dry wandoo and tuart the other day not a prob at all.thanks regards
