I just bought a Delta JT360 Jointer. It has an open base with a 4” dust port on it. I don’t know if I am doing something wrong, but a lot of wood scraps are coming out towards the in-feed table. It is to the point that it is hard to lay the board flat because I keep putting the boards down on extra scraps. Is this common for this type jointer, or do I have something hooked up wrong. I know I have the dust collection on correct, but could I have the tables too close to the blade, and thats not letting the scraps pass through? Any insight would be appreciated.

I had the same problem with my closed based 6” Delta.I had used it for about a year before I connected dust collection to it.The DC was barely helping.One day I decided to clean around the cutter to see if that helped.I stuck the DC hose right over the cutter and cleaned for about 15 minutes dislodging every bit of dust and shavings.It works great now.It seams that the dust lodged all around the knives were preventing air flow.I can now joint all day with only about a half cup of dust on my machine at the end of the day.

I appreciate your feedback, but this is literally a brand new machine. I might have joined 3 edges before hooking the dust collector up. Thats the part thats tricking me. Is it possible to have the tables to close to the blade for dust collection? I would think the machine should collect air ether way.

Could there be packing material stuck up inside the collection chute?

when i get to fast on the jointer ,
it builds a dam of sawdust ,
and can pack in real tight .
i have to use a stick
and an air hose to get it all out,
then it works fine .
same with the planer ,
it clogs on the sides of the cutters ,
and will keep the head from lowering .
if the vac. gets full or clogged ,
it all happens again .

You were all right. The maple boards I was planning kept clogging the very top part of the shoot. So even when I would clean the whole thing out, I would do a few passes, and it would clog it again. I couldn’t see it when I opened the shoot unless I got down on the ground and looked up. It was clogging up so often that I ended up using clamps on the dust port instead of screws so I could take it off quick and clean it.
