Tilting of de table! Raising/lowering de table. The bottom of the segments be floating and pivoted.

Believe it or not, I think I am following you and I believe it could be done just as you described. But I think you might need to be a watchmaker to construct it!

There be one lurking around here!:rolleyes:

Nev mind.

He's a clock guru.

But I think he would be up to it.

Anyone with a shop in a laundry room has to be quite capable of many things.

I thought of mentioning his ability to tolerate 'Ralph' but thought better of it(almost)!;)

Sorry newbies! The old salts will understand. No I have not been here long enough to be salty!

This morning I set up the dado blade to make a cut.

Here's a photo showing the dado blade in place and the insert removed to better show the accordion deflector.

The result of the test cut.

The result that counts.

I recorded a video, below the table, and posted it to YouTube. Here is the link: http://www.youtube.com/watch?v=Eq9yq1mKC88

I am very pleased with the result, especially as dado cuts usually leave large piles of fluffy chips all over the carriage.

Of course I also tested a standard rip cut.

The result that matters.

I also did a YouTube video from below the table (forgot to get the final result on the video:mad: but you can see it in the photo). Anyway, here is the link:

Very happy with this result!

I have never seen anyone store the CHUCK with a magnet on the headstock before!!!

Deflector looks good. Does the video expose the source of that which escapes?

I think it would be unreasonable to expect any better dust collection than that. Great job.

Now, if we could just do the same thing with the table tilted.

Actually, I can. BUT, the effort required to do so is unreasonable. A more flexible deflector that does not interfere with the tilt AND does not interfere with the blade is required. I have not yet come up with that.

I knew that you would spot that, Eagle Eyes! That magnet is actually a magnetic parts dish from Harbor Freight. Can't remember whether it is the 4 inch one http://www.harborfreight.com/4-inch-mag ... 90566.html or 6 inch one. http://www.harborfreight.com/6-inch-mag ... 97825.html

I think the videos suggests that some dust is escaping the tie bar side and some from the front. I also suspect some from the headstock side. In short, everywhere. But less than without the deflector for sure.

If I get ambitious later I will do a tilt test. It works but it does require some bending/folding over at the top of the deflector. I will be on the look out for an even better material to make it easier.

algale: Your results are better than were mine which (I think) means your deflector is doing a better job than mine did at that point.

I have modified my original approach. The modification greatly improved the results.

This video shows what I had until I modified the deflector to rap around on the side. In the video you can see where much of the saw dust comes from.
