Anyone have an outstanding plan for a RAS dust chute? Yea, I know I
can buy it, but...hve 4" hose running to the RAS

I meant to save a link for a chute. Someone posted a link where they
made a chute with a curved back that seemed to work well. I just got 4
pieces of 3/8" plywood. I made the sides about 14-16" tall. I put a
top on it and punched a hole in the back. It keeps the dust under
control with a bonus hose attached to the dust port on the blade
guard.

I don't know about the "outstanding" but here's some pics of mine.
The top and sides are 1/2 Birch ply; the bottom and back is 20 gauge sheet
metal.

Nice looking dust chute. Your design points out an important design
tradeoff that anyone building such a chute needs to consider. From the
[lack of] kerf marks on your table, it looks like you use your RAS
strictly as a cutoff saw, with no miters of bevels (or rips for that
matter, but that is not relevant to design of a dust chute. So yours
extends fairly far forward, effectively shrouding the blade during the
beginning of the cut. But if you were to do a bevel cut, it would be
poorly aligned to pick up any dust (if I am understanding your design
correctly).

The other approach is represented by the store-bought dust pickup I
have and not real happy with. It is flared to pick up dust from a
larger area, and the mouth of it sits even with the column. It picks
up a lot, but a lot is missed, too. Its advantage is that it can be
swiveled about the column, keeping it aligned with the blade during
bevel cuts.

One improvement I have seen on a guard for strictly cutoff work (and I
think this was in Charlesworth's Furniture Making Techniques book,
although I can't put my hands on it right now) is a telescoping dust
chute, with a shroud around the blade that slides into a chute like
the one you have built, keeping dust collection as close to the cut as
possible, even as the blade is moved through the wood.

Here are a couple of ideas:

way down the page)

I did something a little different. I will try to post pictures this
weekend.
