Project Information

Wanting to build a downdraft/outfeed table for a while now since I do a lot of sanding/shaping/carving with my intarsia, I searched LJ and the internet for ideas. I was happy with a style that I found through Clint Wenthur, the link to his project blog is here: http://wenthurs.blogspot.com/p/blog-page.html and to his complete photo album here:

Thanks Clint for the inspiration and insight.

I changed and modified his style a little to better fit my needs…mine is on locking castor wheels, has an overhanging table top to easily clamp on carving tools/sanding accessories, and a metal screen running underneath the holes to capture any small intarsia pieces that may slip out of my hand and can be saved!

I started with a repurposed furnace blower my brother-in-law gave to me. After initially setting it up, the motor was bad so I decided to also upgrade the power at the same time and make it a multispeed motor…the new motor is 1hp up from .5 hp and is 3 speed compared to one speed. The local Grainger outlet was super in helping me out to order the correct motor and multiple speed switch.

The case is made out of plywood with some 2×4 sections internally for bracing. I used two sets of 20"x20" screens, one set disposable and the more durable reusable/washable kind. There is also a 4" dust collection port that allows for the dust trap area to be periodically cleaned out.

I put on a quad outlet to be able to plug in all of my hand sanding/carving tools and dedicated a 15amp circuit for everything. A big thanks to Ron F. for helping me with the wiring of the fan and running the dedicated circuit to it.

This table was also designed to be the same height as my table saw to help me more safely cut sheet goods and longer planks. It works great, isn't that loud and it really sucks!

I like it, good idea! If j had more room in my shop I'd try to emulate.

Adding to my favorites. Once I move, I will have to add this to my list of things to do.

Health first!

I like it! Especially the sucking part of the design. The picture perspective didn't look like the table matched the saw, but the explanation helped. Is there a dust collection system attached?

The table tops are the same height, or within a 1/32" to 1/16" of each other…the downdraft table being slightly lower so the material being cut wouldn't "catch" when approaching the table. The picture perspective does make it look like a greater variance.

The blower fan creates a vacuum within the table via blowing out an exhaust outlet. I have a dust collection port installed for cleaning out the unit, but it is fully functional with the blower motor by itself…the dust collection is not used while in operation. that's the purpose of having a 1hp motor driving the squirrel cage fan. Hope that answered your question.

Having seen (and in a very small way, participated in) the assembly of this table, I can assure everyone that it is built to the same exacting quality levels that Joel puts into all of his works. Another great project, pal!

That is really clever. The furnace blower and removable filter are neat.
