outfeed/downdraft sanding table

Listing #94   Listed on: 09/22/2013

I needed a new outfeed table for my table saw, someone gave me a blower motor, one of those squirrel cage motors from a heating system.

I built the table from 3/4" birch ply, made the top from MDF, placed 2 ribs underneath the top to keep it straight.

I sprayed the top with prekat then a couple coats of hard wax.

it has 4 heater filters.

The table has surpassed my expectations,

I always disliked sweeping the shop in the winter due to the dust cloud that would hang forever, now when I sweep the shop I turn on this table and the air is clear in no time.

Also I installed a 1hr timer to the table, so if I'm sanding or the shop is filled with dust I can turn on the timer and the go to lunch and it's cleaned by the time I get back.

The most expensive part of the table we're the heavy duty leveling feet I installed on it.

If I was going to change anything I would add a kick space for my feet while I'm sanding.

In the future I may hook this thing into my dust collection system.

Wow! Be careful with that! All of those places for hang-ups in an out-feed table is a disaster waiting to happen. At least, continue the dadoes all the way clear until you can find a better place for this, or until you can redo the top in a safer way.
A safer top could be made with lots of 1/8" diameter holes, and hit them all with a countersink. Cut your miter gauge slots first next time, so you don't have any edge penetrations. I'd still be aware of the possibility of a hang up in certain situations, but as it is, you're running too much risk.

Mark,
Appreciate your thoughts, what I didn't say in my description was that I've had this table for 12 yrs. In all these yrs I've never had anything hang up on one of the holes and I use the saw every day. I just don't think it's a concern in my case but thanks.
Gregg

I like your idea of double duty table. It all makes sense, however, how would you tie it in to you dust collection? And I see that there is a vent on the bottom side...would than not detract from suction on the top?

There is not much discussion of the air handling part of this. It looks like the filters are in tandem for extra elimination of dust.
Does this thing perform well for other than settling dust after sweeping? Do you sand on it?
Air changes per hour is a good indicator for someone considering something like this. I think this is a nice idea and also think the air flow capacity wants to be robust for many woodworking operations.

I hook a hose to my sanders, do most of my router work on a router table (with dust pick-up) and vacuum my floor with the same hose. Fans exhaust the air.

Very cool! Bottom vent would be for air discharge, right? How orten do you have to change filters?

I built a very similar table but used a AC/HEATER blower and filtered the intake side of the blower with 2 filter slots. First for a cheap ac filter to catch bigger stuff and second a better filter for fine dust. The unit also doubled as a room air cleaner. I used bigger holes in the top and also never had any hangup issues of any kind.

You want to go to a deeper filter 2 or 4in.
Running filters doubled up adds resistance.
