Driving Me Bananas

I was set up to take the first slab off, but when I started the cut it pinched hard, slowing the bandsaw right down until, it was smoking with the fricton . But after thumping in a wedge it was free ,this happens now and then but todays problem log was a wind blown tree. How do I know this through many years of problem logs! The ends of the log won't reveal much if there's dirt and dust but when its clean and first cut this would be more apparent. When the first slab fall's away if its a wind blown tree a dark line of moisture will show up along one edge.
This line of moisture shows up when a tree is blown down in a storm, the downward side of the tree is still being fed by the roots .If this is left for a long time before being cut off at the stump, lots of tension starts building up along the underside of the tree. Which causes severe deviation when cutting.
Luckily this was a small log so not to much time was wasted, from sticks like this ,banana and corkscrew timber is likely to be cut . And yes I'm getting used to this new computer :)


  1. Interesting - I didn't know about that.
    I think you must have sold that tree to Jewsons last week and they delivered it to me to use as studding!

  2. Not me mate we scrap all the gash bits like that. Or cut smaller section stock to salvage what we can :)

  3. Over here, there are a few mills with "floating heads" or whatever they call them that make the next cut at same depth, no matter how the log springs. Proper stacking supposedly allows the boards to straighten in drying. It seems to me that would retension the boards, but with big mills, it's about production, not quality.
