I recently finished a piece of furniture in walnut for my wife’s computer. After hours of sanding to 220 grit I got the finest dust covering every square inch of the shop. It is disgusting to touch anything and see a cloud of dark brown sanding dust floating in the air. Fortunately I used a N95 mask to protect the alveoli of my lungs, however I would like next time to stop the dust at the source, I tought a sanding table with a plexiglass hood should do it, however those tables in catalogs are quite pricey, most likely I will build one. Any suggestion as to proportions, optimum size of holes, should I suck dust from the table and from the hood at the same time or this is overkill?
Any suggestion is appreciated, ..as always.

Here's an idea. I built a box of 1/2" plywood, about 6" high inside, and 20 x 45 or so. On one long side, I cut a 4" hole for a DC hose, and on the top drilled 1/2" holes in a grid about every 1.5" or so. Use it as the sanding table with the DC and most of the dust is downdrafted; very little is airborne. My size was determined by the scrap available. Cost was zero. I know there are fancier plans, with interior ribs and such to maximize the collection of dust, but my simple one works pretty well.

I have made a very low tech sanding table like the one described in this post. I do most of my sanding with a random orcital sander from Porter Cable. My model has a rubber boot that surrounds the spinning sanding disc and is connected to a shop vac. It really works great. Now I just need to figure out how to handle dust from lathe sanding.

Don,
If you have a good shop vacuum with floor attachments, you can build this simple jig I created for lathe dust collection (See the following post for a picture). The materials comprise of a few scrap pieces of wood, a few wood screws, and a single carriage bolt with a large washer and a wing nut. The unit is mounted onto the lathe's rails, and can be positioned anywhere along the work piece simply by loosening the wing nut.
If your vacuum has two hoses, use the one with the larger diameter. Slip the hose through the holes in the jig (the one closest to the work piece is taller to angle the hose upwards), and then attach the floor sweep. This will keep the hose from falling out of the jig. If you find the hose twists, wedge it in place with few thin scraps of wood.
Please feel free to send me any questions that you may have.

Don,
Here is the picture of the lathe dust collection jig I described.

Thanks Dan,
Very good tips.

John,
Another low tech option is to buy a cheap $3 20x20 furnace filter and duct tape it to a box fan. Position it right next to your sanding job. Works for me. My ROS dust collector works pretty good but I still use the fan. My old belt sander has no dust collection to it, I used the fan and a mask this past weekend.
I am thinking of a homemade sanding grid/table. My idea was to use the hole in my workbench where I place the router table top.
My next ROS is gonna be one like that Don. Sounds cool.
Enjoy, Roy
Who typed that mess!
