I have a new Jet jointer (6 inch) just assembled it yesterday. It is correctly assembled, but the chips fly back in my face and on top of the infeed table. I’m taking a 1/32 cut and I have a large jet dust extractor hooked up and running and still get blowback…. so what’s wrong?

Maybe nothing, maybe depth of cut is too much. Couple of questions, does this have staggered knives, or 3 solid knives? What is the depth you are taking?

Does it have skirts? Are they on? Or an open legged machine. Are you getting anything into the dust/chip collector?

For giggles also put down the model number of the JET you bought, all tools are not created equal. It’s possible an owner of that machine could tell you what they get.

It isn’t a stretch that some chips do fly out onto the infeed table. I have seen skirted machines with the skirts off, and they had terrible chip collection, put the skirts back on and problem went away. Some unskirted machines misbehaved until plywood skirts were added, suction almost always improves with a better enclosed machine. Not seeing how much you are getting back I can’t really tell you much.

It is so difficult to help with a problem with no model number or pictures. Please help us to help you.

If it’s brand new is it possible that there is something inside (packing?) under the knives? That’s what mine does when it is clogged. There is nowhere for the chips to go but up and out through the top. Is it an enclosed model with a 4” dust port?

+1. That’s the first thing that popped into my head. My JJ6 only does that when I’m lazy and don’t hook up the DC and it gets packed with chips.
