Step 7: Easy Heavy Duty Shelves

These are the stock shelves by the garage door at Emeryville Squidlabs.

Look carefully. This is a very strong set of shelves made without any rabbets or mortises.
The whole thing can be made very quickly with repeated square cuts.

The vertical boards are 3/4" plywood with 3/4" square plywood cheekpieces sandwiched against them.
The ends of the 2"X10" shelves are inserted in the gaps between these square cheekpieces.
The 1"X2" end caps on the verticals keep the shelves constrained horizontally and stiffen the verticals further. The top of this shelving unit supports a storage loft.
<p>That's great! Rumor has it Benjamin Franklin used one of these.</p>
<p>I made a chair like the ladder chair. The links below in the comments helped me get the plan</p>
What is this type of chair called? I would really like to research it a bit.
http://tech.cls.utk.edu/wood/projects/bogchair/bogchairplans.htm <br> <br>Bog Chairs
About the 2 piece chair. Is 3/4 inch pine really going to hold my big fat, 180lb butt? Or should I use 1 inch thick oak instead? I'd love to make one of these. <br>
I weigh 290 lbs i made some of these of 3/4 plywood they won't hold up under my weight i'm making some out of solid 1&quot; walnut this time should hold up very well the plywood ones will hold up 160# or less kids love them around the campfire <br> <br>But if you do make some out of plywood don't leave them out in the weather as it makes them weak and they bend and break after a few rains .....
I didn't know these were also made in Africa. I've always heard of them called &quot;Stargazers&quot; because when you sit back in one you're looking up at the stars. I have also heard of them called &quot;Bog Chairs&quot; because there was one found in a bog up north in europe and that it was made by Vikings.<br><br>I make these.<br>
I think these are gorgeous! Mind if I copy them?
LOL video for the cardboard box chair &quot;is that comfortable?... Hell yea&quot; LOL
liruke gave perfect directions and measurement specs.<br><br>A few comments:<br><br>The wire is just to hold the initial assembly together to verify everything was cut and drilled correctly. The chair is held together with threaded rod, but might be done with rope or even wire. The stresses are shear except at the ends, but a good knot would do with rope. Rope or wire would give the chair more &quot;give&quot;.<br><br>The chair is made from 9--1 1/2 x 1 1/8 &quot;sticks&quot; if you go the 2x4 route. Any stick lumber near those dimensions will work. I have an unlimited supply of bamboo, which i plan to make one of these chairs with.
This is a similar construction to a 'Holy Book' stand I got back in the '70's.
Do you have a list of materials? measurements?
You start with three six foot 2x4s ( I used pressure treated pine), ripped into nine equal 1 1/2 x 1 1/8 pieces. By judicious measuring, this should yield the following: Seat: (A) 6 pieces 15" long ) each piece has two 1/4" holes (B) 2 pieces 35" long ) drilled in the center of the wider side.Measure from the same end: 1st hole 1 1/2"; 2nd hole 12". (C) 9 pieces 9 5/8" long: Two holes, 1 1/2" from each end. Back: (D) 4 pieces 31 1/2" long) Each piece has two holes, at (E) 2 pieces 29" long ) 1 1/2" and 25" measured (F) 2 pieces 42" long ) from the same end. All held together with 9 gauge galvanized wire.. Align seat pieces as : A-A-B-A-A-B-A-A and hold together loosely at top with a length of wire through the upper (1 1/2" holes); At the lower (12")holes, intersperse each piece with a length of C. That is: C-A-C-A-C-B-C-A-C-A-C-B-C-A-C-A-C. Wire and set aside. Align back pieces in the order F-D-E-D-D-E-D-F, and again hold together loosely with a wire through the holes which are 1 1/2 from the end. Now marry the two parts by threading wire through the remaining holes, with the C pieces acting as the connectors. The new joint should have the configuration: C-F-C-D-C-E-C-D-C-D-C-E-C-D-C-F-C. Draw all wires tight, cut off and secure ends somehow (I threaded them and used cap nuts). Now take it all apart, sand as appropriate, finish as desired and reassemble. Note that this darn things folds too!
Great project.<br>Could you explain further, or give a photo, of what you used and how to finish off the wires?<br>It's probably a &quot;DUH!&quot;, but right now I don't know how to do this.<br>Thanks
I thought I should expand on my confusion -it's with your statement &quot;It's held together with four threaded rods with nuts and washers on the ends', but later on you say it's all held together with 9 gauge wire. <br>I must be missing something. :-}
Thank you so much for sharing. It is a beautiful chair. Where could I find the specs for this chair? I would like to know how high off the floor the seat is and the instructions can be revised to make it a little taller. Although very comfortable, the pictures seem to show an extgremely low chair. Thank you! cr
Mr. Anderson, your Instructables are awe-inspiring. i always look forward to seeing new projects from you. i love the instant cardboard chair! i finally know of someone else who does that. i will certainly be putting some of your ideas to use next time i build up enough motivation to rearrange and downsize my belongings.
You can simplify construction. Instead of the hole, cut a slot the thickness of the wood in each piece so they slide together like the seperaters in a cardboard wine case. <br />
It will not be near as strong as the authors chair. You may end up with a broken tailbone or more or less.
My first laugh as well. Thanks!
i've been doing this in my dorm room and a really easy way to make them stay together and stable is zip ties. those little plastic ties that are really cheap and readily available at hardware stores will hold them together even if you load them with books. just put about two to each side through the holes in the sides of the crates<br />
my family created campfire seating out of an old staircase we took off of the cottage...<br /> just sawed it into 3-stair pieces and attached thick planks to the backs and sides to hold it up. it works great.<br />
You say they're sturdy. If they're set up, will a fairly well made one withstand a 70kg man crashing onto it? serious question, because it looks like it would snap at the join
I made one of these a test piece also out of cheap 1/2 inch plywood. It held my weight no problem. Im close to 200 lbs. I would not use plywood but I had some scrap wood laying around. I am going to make a nice one now with real wood and do some nice wood carving on it,.<br />
i just made one from acrappy woodworm infested&nbsp;plank (prototype version) and it takes my weight just fine - i weigh 16.5 stone , i think thats about 220 pounds? they are suprisingly strong and&nbsp; again suprisingly comfortable!
I mean the african chieftain chair
I saw this in National Treasure!&nbsp; <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> Just saying.
measurements for the base pieces?
the third photo is a side view. scale the photo so the seat is as high as you want it to be. Then measure the other sides. they will be properly proportioned! this process is called "photogrammetry" which is faux greek for "measuring photographs". It's a big deal in europe because they destroy all their buildings every fifty years or so in big wars and then try to rebuild them from photos and paintings.
i have one of these chairs, everyone in my family fights over who gets to sit in it
There is a debate weather or not vikings used this style of chair as well
<a rel="nofollow" href="http://www.popularmechanics.com/home_journal/workshop/4226197.html">http://www.popularmechanics.com/home_journal/workshop/4226197.html</a><br/><br/>This style is a benjamin franklin library chair, plans at the link above<br/>
My first laugh of the day. Thanks!
For everyone looking for plans for the ladder chair: There's a plan on the Popular Mechanics site for the ladder chair (Step 10). I saw it a couple months ago. <br/><br/>link: <a rel="nofollow" href="http://www.popularmechanics.com/home_journal/workshop/4226197.html?series=20">http://www.popularmechanics.com/home_journal/workshop/4226197.html?series=20</a> (or look for the 3D workshop). <br/>
awesome, thanks for the link Also, for anyone building the two-board chair, make sure to get hardwood
I want that ladder - chair sooooo bad. I can kinda guess what I will need to make it, but are there arny plans/measurement to work with? That would be awesome if it's out there somewhere...
Is there a picture of the chair folded up?
do you know if this would work with masonite boards?
i made <a rel="nofollow" href="http://www.instructables.com/id/Learn_About_Mid_Century_Modern_Design/">this video</a> on mid-century modern design (Eames Era)<br/>
I think I found acpl, of those chairs by drunken mistake 1 time after moving , very comfy .LOL, good job . I needed a laugh , thanks
Can you post more on 10? Blueprints, etc would be helpful
Actually a library chair. Something to sit on as you read, after you got that rare book down from the top shelf. I think it is an English design. They are still made and the mass produced version sells for about $150.00.
lol i made a lean-to, with a poker table, and chairs out of............................................ FIBERBOARD!
There's one on the deck from a houseboat along the way walking from trainstation Amsterdam, Holland to Sience Center NEMO. I love the simplicty.
i work on a packing bench and theres some great makeshift furniture there, theres cardboard boxes taped together with chipboard tops, theres shelves made of cardboard, its awesome.
post pictures!
Any chance on getting measurements or a pattern for the many stick folding chair?
I think I'll skip the carving, spray paint it instead (I'm a pretty good painter and I imagine my carving skills are probably less than proper), and layer it with some acrylic clear spray so it won't rub off. Awesome Instructable!
I think I will try to convert an old chair to something like this step ladder chair. I'll probably use flip-top hinges so one does not have to sit on the pivot pin. (e.g. <a rel="nofollow" href="http://www.leevalley.com/hardware/page.aspx?c=1&p=40574&cat=3,41241,41261">flip top hinge</a>). Has anyone played with making or converting to this?<br/>
OH I for got one thing, they are <strong>comfortable</strong>!!!! and sturdy.<br/>
