'Why I hate sawing Spruce'
By Swing blade Andy.
Most of the Spruce trees I got to saw were edge trees. Shelter trees, very low grade logs indeed.
There was a never ending list of problems.
1. The value of the timber was so low that I couldn't justify my cutting charge to the client unless he wanted beams than then it was touch and go. HE could buy the timber form the hardware at about 130- euro per cubic meter. Which is for nothing.
2. Most of the trees I was given to cut were from fence lines and so were full of wire, nails, bottles, bullets, steel bolts and all sorts of this stuff not good for the saw.
3. When you do get a log under the saw the resin is very sticky and there is lots of it needing a flood of water to prevent the blade gumming up and then heating up...... destruction of a blade.
4. Even if none of the above occurs and you’ve got a half decent log under the saw the knots a so hard that the rest of the wood so soft so that you can race along and 'bang' you hit a knot. Sometimes its enough of a shock to loose a tooth, than the following tooth hits the loose tooth and your changing blades (again).
5. The texture of the timber features very long fibrous grain, which is great for many building applications. But it never seems to cut clean; some of the fibres tear and so leave a fur. This is sometimes enough to increase friction and therefore heat in the blade. If it heats up enough then it buckles and 'whammo' your blade tension is gone. Change blade again and its back to the saw doctor for re-tensioning. But its never the same.
I gave up. Anyone who had spruce trees of anything like them I recommended cutting them with the chainsaw for the fire. I sold only Douglas for construction... None of the above problems. Lovely.
The end.
