I've been getting a lot of use out of my homemade disk sander, but I tend
to get a lot of dust thrown about with it. I do most my sanding work on
the downside of the rotation, so the dust would be thrown towards the base
but some hangs on and is thrown further.
If I installed a trap, such as a piece of angled wood, would it reduce the
amount of dust that gets free? Do I need to do something else?
You can only do so much with caulk, cardboard, and duct tape.

shopvacs don't make very good collectors for machines that produce a
lot of fine dust, but you can do a few things to improve the
situation. first, make sure that the vac filter is clean and that the
hoses are airtight and not kinked. build a shroud around the disk
sander that makes the air flow the direction of rotation and directs
it into the vac intake. you'll probably need to experiment a bit to
get a shroud shape that flows well and collects the maximum dust while
still allowing you to use the machine in all of the ways you want to.
you may even end up with parts that you remove to for instance get to
the edge for some operations or to allow sanding of long boards. but
generally a shroud that encloses the full circumference will catch the
mostly I end up making dust control shrouds from plywood, sheet metal
and plumbing fittings.

Just yesterday I was turning and then sanding an oak spindle. I
spring-clamped the 4" DC hose just under the spindle and it looked
like it continuously sucked the dust. The pattern was rather cool--it
looked like an ocean wave. Sanding and bandsaw work produce a lot of
fine dust. Your dust collector can work wonders for cleanup and your
