What did I do wrong? You had a blade pinched becauseit dropped on either side Oh, I see, and thenthere's tension on there.
When the motor's, when you hearthat sort of thing, you're like "Ugh" immediately becauseit's like damaging itself as it's doing that.
That's fine, it should be fine.
Now there might be a littlerubber smell from the belt.
So, what happened here isas Paul was making this cut, the blade cut deeper and deeperuntil there was just a tiny little corner of wood left,and that little bit, was just a bit too flexibleand with the wood being heavy on either side,and only supported by a small table saw sled,it came down on either side and pinched down on thatblade and stalled it.
This sort of blade pinchis more often experienced with a hand held circular saw.
Ifyou're cut ing a piece of wood and it's not supportednear the saw.
But, it's easy enoughto avoid by making sure that the piece of wood issupported near the saw, and the piece that'scut off will drop down but maybe not too far,when it's cut.
>> Paul: What causes burn-out?What am I doing wrong? Am I going too fast or too slow?>> Matthias: Too slow, yeah.
No problem,I did the same thing.
Yeah, yeah, I mean,this little thing is where When ripping a rectangularpanel, like this, a lot of people, knowingthat the blade is dangerous, try to push the wood as faraway from the blade as possible and that actually makes it worseSo imagine we're actually making a cut instead of grazing justthe top of a stationary blade, if I push here,the blade is pushing here, and that givesthis piece of wood rotation, and it wants turn like this.
Now, as we're finishing thecut, and I'm still pushing against hereand not enough against here, as I get to the end of it, the rotation of the blade wantsto lift this piece of wood up, and it'll jam in therereal good, lift it up and this happensin a fraction of a second.
Now it's on top of the bladeand now the teeth are just pullingthis piece of wood along and keep in mind this is goingvery fast and this piece of wood now comes flying, and gives youone hell of a bruise in the belly, if you're lucky.
No burn, yet.
In terms of burning on the cuts, sideways pressure on theblade would make it worse, a dull blade makes it worse,harder woods make it worse, but also cutting too slowly.
Now, if I want to cutthrough this piece of wood, and my saw has only got1 3/4 horse power, I won't be able to cut thisfast enough to avoid it.
Okay, that was a devil fail.
I was sure this would burn with me cutting this slowly,but if I need to cut to this depth,in hardwood with my saw, I tend to do thisin two passages like this.
So, even thoughI had to make two cuts and raise the blade in between,my total cutting time was actually less.
This is the kind of just made and this is the previous cutand actually looking at it now you can see some stainshere and here.
