A Chair with a bit of a back story.

In the interest of putting off our real work around oomlout we set ourselves a simple challenge, make a chair. What ensued a day (well we're a bit disappointed as it took closer to half a day but we digress) where we went from figuring out what size a chair should be through computer drawings, cnc cutting and finally assembly.

(shameless plug)
If you'd like all the details they can be found on our blog:


You'll need to format the drawings to suit your own CNC machine (sorry no g-code our machine is from the late eighties and functions on super proprietary programs (TPC FTW?)). Then cut from any 1/2" stock.

In terms of joining it all together, what is required is 16 1/4" x 1 1/2" bolts and 16 matching nuts.

(an aside)
While we love the chair we produced we would recommend the following improvements.
-improve rigidity by adding support bars on the uprights.
-unless you have a very large bottom the width could be reduced by an inch or two.

Made one yesterday with the universities water jet as part of my research. Found some scrap out back and within the morning she was all cut out ready to go. Had to adjust slightly to suit the 12mm ply and bed size. Thank you for providing the file.

I made the One Day Chair out of 12mm MDF that I cut on my laser cutter. Wasn't very fast to cut but still a fun little project. I did make a chair a little narrower so that I could nest the support within the base of the chair. I did this so that I used less MDF. ;) See my pic above.

Wow it looks really good.

We're feeling a bit guilty about not adding that it might not be the comfiest of sitting options.

No it's a cool little demo piece. Now i somebody ask if our 120W laser can cut 12mm Ply of MDF I can just point to the chair in the corner!

Thanks for the design Stuart!!
