I had this issue when I first bought my Mill. Spent weeks trying to figure out the problem and checked and rechecked and rechecked every component that needs to be aligned and adjusted but it still cut wavey.  Im the end it was the Bands themselves that was the issue. They where Bacho bands and they where to thin, so even over tensioning did nothing to help. Someone recommended getting Ripper 37 blades and that solved the problem instantly. The plus side is I now know my Mill inside out and its adjusted to within 1mm and most likely 0.5mm everywhere.  

 

Other things to check is you tension set right? Try and over tension a little and see if that helps.

Are the wavy cuts at knots? This can have an affect on your blade wandering up and down.

I guess you have a series of alignment checks and adjustments to perform on the Band Wheels, bearing guides etc etc? Could be worth re-checking all these in the correct order.

 

Id order some Ripper 37 bands regardless, they are great (unless you-re already using them) so if you spend the next couple of days investigating the issue and still have not got it sussed then you'll have the new blades arrive and ready to try out.

 

Call Steve directly and you can order less than the 10 blades stated on the website. '

no idea, whatever Woodland Mills use. how many hours of softwood before they need sharpening/replacing?

just opened it up and cleaned it out. the blade is out of line on  one wheel so will try and correct that tomorrow.

also, i wasn't bothering to clamp once i was on the flat bottom. never did with chainsaw mill but will see if doing it makes a difference

I totally agree with Andy's advice - Ripper 37 are the blades to use from Stephen Cull.  But to answer your question - you need to change the blade often.  If we are cutting all day we get through 5 or 6 blades, so changing every hour or so.  And not because we are cutting muddy logs or hit metal.  Just these type of bandsaws need super sharp blades.

 

Also you could be going too fast with the cut.  So try a new blade, (preferably Ripper 37) and if still wavy try slowing down.

WHAT??? bloody hell. didn't know that about changing blades! i am going as quickly as possible, couldn't resist after the slo mo of chainsawing. i was going to ask about mud but figured it wasn't as important to avoid mud with blades as it is with chainsaws but still need to do. will start using my skidding cone again.

Around 4 hrs cutting time on new timber on the woodlands but if hitting mud or muck that will reduce that by half at least.
