Been working on some products to sell at a Christmas bazaar at my kids school next month. Items can’t be more than $20 so I decided to make some small cutting boards to go along with a bunch of wood Bookmarks.

I got about 7 boards glued up & sliced yesterday. Today I need my router table to round over the edges. Didn’t want to fill the garage with sawdust again so I decided to build a downdraft box for my new to me Rockler Router Table.

Made the box out of 5/8” MDF with laminated Melamine top and put it together using my Kreg Pocket Hole System. If I did it again, which I likely will, I would use either Plywood or I would glue the box together. Since I only had MDF on hand and didn’t want to wait for glue I ended up with a not so well built but very functional downdraft box.

Cool part of rounding over the edges is I get to use my Campbell Hausfeld pneumatic Random Orbital Sander. What a fantastic Sander. It is self vacuuming!!! Soooo cool!

a) Do I understand right—that pneumatic ROSs use a LOT of air (require a high SCFM compressor) ?

b) Really nice job on the box. Does it need/have anything other than the reducer ring opening, on the router insert, to provide it with the ‘intake’ air ? Does it work really well, just as it is, for dust extraction ?

First of all, Great Cutting Boards!! hope that go well at the Bazaar ;) Secondly, Nice down draft for your router, I bet it works well. If you are like me you will be to busy to stop and remake it ;) Thirdly, Did you say your router table was new to you…. Does that mean that it was used? Where did you run into a dandy table like that used?

Thanks for sharing!!!

It’s looking good to me! How do you like that fitting on the d/c hose? I’ve wondered if its as good as the advertising suggests.

Great idea. Great for you health also. and besides, if it works, that’s all that can always upgrade it later, cuz that’s what we do :)

Yes the ROSs is an Air Hog, I have an 8 gallon Harbor Freight compressor and have to wear earplugs when sanding because it is running constantly and I have to let it refill every 5 mins or so. That is fine on a project like this but would get annoying for a large project. However, the sellf vacuuming portion makes up for all the downsides. I have an electric one with the little bag on the back that is a joke for dust collection. This is the real thing as part of the incoming air circulates back out to the vacuum bag. I wouldn’t dream of using that thing on anything less than a 2hp compressor.

Yeah man I go the table on a CL steal of a deal. Guy moving cross country and got rid of his whole shop.

The dust collection works fantastic, with the hose going out to the back of the fence I think their is enough air flow so far. I think it needs some baffles to guide the dust.

I used all Rockler “Dust Right” products. The hose, the wall hanger, and all of the connections are 4” Dust Right products. I have severe allergies and nasal issues so the extra money to make sure all of the fittings worked together was well worth it to me. When I first got my D/C I tried mix matched brands and got some pretty poor results. After That I decided to just stick with one Brand for all of my fittings.

Since I wanted the Dust Right Hose Storage Rack I decided to go with Rockler. The Hose Storage rack is so-so, only good for storing the hose overnight or longer periods. It is quite the task hanging it up in a way that it will stay up so it’s not something I want to do more than once a day. Other than that thought the rest of the fittings are perfect! I really like the keyed clamp rings too.

Great idea for the dust collection. Is the top hose supported or is it just coonected to the 4” reducer?
The reason I am asking is that the weight of the hose will cause the fitting to pop and ultimately break.

I love the boards. I see you are using all the nice wood you got last time.

The small hose coming from the fence is made exactly for the purpose it is being used. It’s the whole Rockler Dust Right line. It is about 3 feet long and hooks directly to the Router Table Dual Port. Pretty slick setup. Plus when I upgrade to an Incra Wonder Fence it will connect right to it.

I pretty much HATE having to use reducers. I have to use one with my Shopsmith and it is a real pain in the ass. I have to jury rig it together and then have to take it all out to move the headstock or change blades. Plus it’s unsupported so like you said, it will eventually break. But I will have to live with it until I can pony up and buy a SawStop.

Oh & the Purple Heart was reclaimed 12 years ago in the midwest where it was being used for industrial fan blades. Which is about the oddest use for an exotic African hardwood I have heard of. The Walnut came with the Lumber Rack along with the purple heart. The Maple & Jatoba I purchased about 6 months ago for this specific purpose. This is the 3rd round of cutting boards using those boards.

Up next is a few hundred wooden bookmarks. I have most of the blanks glued up. Just need to build the Bandsaw Table in the next couple days and I will be off to the races. Slicing dozens & dozens of thing strips of laminated wood. Saw your thin strip ripper, probably make one of those too.

Great idea!

I really need to get my dust/chip makers under control.

I like this quite a bit. I’ll have to build something similar for my table.
