« Part 7: Closing up the bottom Part 8 of TS outfeed table with downdraft series no next part

I kept some stubs of perforated angle iron I didn’t need when setting up a set of basement shelves…. They’ve been out in the shed for 9 years….. I knew they’d come in handy some day, and today I used one to mount the out- feed table to the bench. I drilled a pair of holes in the Biesemeyer fence angle for the other side and leveled it flush with shims….

Next up is hooking up the DC hoses… Then I need to mount the side boards with piano hinge

That’s a mighty fine looking “Multi-Purpose Outfeed Table”!!!
Now let’s fire that thing up & see (hear) some sucking!!!

SEE THERE? And my wife says I keep too much STUFF!

Nice progress on the sucker box.

Hooked up the two 4” DC flex hoses…

It pulls pretty well for as big as the table is. I can see how the side walls will be needed to keep the dust with any velocity contained in the ’ suck zone ‘

I think having an out- feed table is a big safety upgrade, as I have spent way too much time leaning over a spinning blade, in order to keep my work from falling off the back end of a saw.

I think white would have looked a lot better….. But free is free!

You are correct, white would be better.
You’d better build another one in white. I’ll dispose of the original for you!!! ;^)

Looks great! I’ve been looking into designing something similar. I’ve been going back and forth on using my DC, or trying to put something together with a squirrel cage fan. Do you think that with only 1 DC hooked up, 1/2 the size of the “suck zone” would work, or do you think squeezing a little more suck would be ok?

Hey Steve,

I only have one DC hooked up…. but my DC has a 3-way ‘Y’ off the inlet, with three 4” flex hoses. Without the ‘Y’ the inlet is 6”. So I wanted to get as much air flow out of the set up as I could… and two 4” pipes was the best option for my layout and equipment.

Bill Pentz has a good article written about this topic here. I found the principles from the article very helpful, but without a true, measured CFM number for the DC (the numbers published by the manufacturer are almost always dramatically over stated), it’s hard to apply the specific calculations. Also, all of Bills numbers are for a square downdraft table…. and because this is primarily and out-feed table for me, it’s bigger than it should be.

I used my belt sander on it the other day, and with the discharge of the belt sander attached to a shop vac (with a HEPA filter), the DC sucking on my table, and the overhead air filter running on low, there was almost no perceivable dust. The most dangerous dust to your lungs is invisible, but even invisible dust from sanding pine seems to have a resinous odor that lingers in the shop, and I could barely perceive that odor.

I don’t really think I’m pulling enough air volume to re-direct and capture the dust as it blows off of the sander, but as part of my overall system, it appears to be working pretty well. I have yet to install the hinged panels for the 3-sided walls, and that should help to keep even more of the dust in the “suck zone”.

If I had to do it again from scratch, I would make the perforated area of the top smaller, and push the sloped walls on the bottom closer to the middle.
