Earlier I spent some time trying to improve on the saw dust collection system that I use. I thought that I had made some real inroads and then this happened! Guess I still have a bit of work to do.

Yep! the shop gremlins relocated to the jointer!:D

Just let the chips pile up under the infeed table. That HELPED mine.

It surprises me that 'debris' collection works as well as it does on the jointer considering the 'chips' are being flung forward AWAY from the 'chute'. Perhaps as Beeg said, let the infeed side fill up. That would cause the chips to leave the blades later(toward the chute).

Wow. I'd never thought of using my jointer to shred Parmesan cheese. I bet you have to do it on a cool day, eh?

These next four images are two before and two after the final fix. I don't have to tell you which is which.

In the second picture, the table was raised so that I could view the dust pattern that collected on the saw guard..

Final Fix Has Been Incorporated

Ed in Tampa, these last pictures prove your theory in that there is some dust that comes over the top. However, I think I am through with this set of modifications until I have had time to do a couple wood working projects. The extent of cleanup will tell me if I must do more.

NOTE: In any of the images shown where the amount of sawdust was the subject being presented, the cut that created the sawdust was a single rip cut through a 3'-4' long through a piece of 1" MDF. I don't have any good lumber that I am about to cut up for testing. That will have to wait for a real project. SWMBO says that better happen soon. She is getting tired of waiting.

This might be silly, but what about moving the dust collection port to the front of the saw guard instead of the back? It seems like the tracksaw guys (eurekazone) feel like that improves performance. Makes sense to some degree - start grabbing the dust as soon as it comes off of the blade post-cut rather than letting it fly all around the lower guard trying to find every nook and cranny to escape.

Anyone consider that? Maybe I missed a post where this was considered.
