I'm sure some of you have experienced the effect of insufficient dust extraction on a thicknessing machine where the chips either get hammered back into the workpiece by the rotating cutter block or by the outfeed roller crushing them into the timber leaving little dimples in the surface, it's quite a common occurrence with planing machines.
But I would wager not many of you have experienced it across the whole face of a board before, and along the whole of its length.
As you can see, the plank is very rough everywhere and so much heat has been generated that the earlywood and latewood have "delaminated" from each other in a lot of places and you can peel big pieces off. Bearing in mind the plank fed before it looked like this, nice and crisp:
"Ye gods" you might say, "How did that happen?", Well...
There's your problem, that's the cutter block completely engulfed in shavings :lol:. So, what caused that to happen?
A couple of nasty splinters (the largest being about 8" long, looks quite small in the picture but the chips around it are rather large and coarse compared to regular shavings) from a previous run had managed to get wedged in the 6" diameter flexi-pipe and enough softwood shavings gathered around them to completely block it, which resulted in the plank being all torn up as the shavings had nowhere to go except right back at the timber and out the back of the machine.
Thought some might find it interesting.
