just a note, books are heavy, and at that price I would hope this is a shelf which isn't falling off the wall.

one option (and maybe this is the case here) is to have a wall mounted metal frame which mounts securely and then this have a metal bracket which slides on to that. There may also be metal pegs coming out of a wall mounted which lock on (maybe what those two dark spots near the middle are).

I've had simple looking shelves which which worked like this.

Here's an example of the peg option: http://www.consmos.com/bracketless_wall_mounted_shelf_hollowboard.html

One serious note, If you are having trouble visualizing (and planning) the cuts here is a simple way to get it right:

- get a 2 by 4 or other piece of wood

- cut two long pieces and two short pieces. These cuts need to be at a 45 degree angle. Each end of each piece should be cut in the opposite direction. For example if you imagined the end angles continued after the wood, they would come to a point (or form a triangle) on one side.

-Now you have two long and two short, glue them together like a box or picture frame (use wood glue and clamps)

-let it dry

-Now cut your box into two pieces at a 45 degree angle

-Flip one side around (should be easy to see how it goes now) and reglue.

In response. I think a 10 foot two by four would be about $5. This looks like less than 6 feet to me. Something with a nicer grain pattern may be more, but it's not a lot. Consider it a training fee, knowing how to make and fix furniture will save you future money.

I'm not a pro woodworker, but I build things often. Since you are new I would say to skip the fancy ways to do the edges and start simple. As for clamps, you do need to clamp wood, but if you don't have the cash you should be able to keep pressure on for the glue. I just made a bunch of picture frames and to glue them I used a metal square box and two heavy weight lifting weights to hold the joint tight. Clamps are easier but you can figure out another way.

You can also do without a miter box, although it's also probably cheap and worth it (but everything adds up). Draw good lines for your angles and cut just a bit outside. Use (and buy) some sandpaper (medium grain probably) to get the edges nice. [since your new i'll mention that you wrap the sandpaper around a scrap wood piece to have a flat sanding edge].

Really the best thing you could do would be to find some scrap wood and try stuff first. If no scrap is around just buy something smaller and cheaper to try first so you can see how it will all work. Something like http://www.homedepot.com/Lumber-Composites/h_d1/N-25ecodZ5yc1vZbqpg/R-100075477/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=wood&storeId=10051

At only 75 cents for 8 feet (it's much narrower) you can try cutting and gluing and all that out first. I'm sure hand sawing through 2 by 4's will not be pleasant, especially if you make a mistake and need to redo things. So just make a mini version first and the final shelf will likely come out much better since you'll know what works.

This look pretty simple. YOu could probably make one with one plank of wood, one packet of nails/screws, a drill, a handsaw, and maybe a quide square.

You could mount it with L-brackets to studs, and it would hang fine. I kind of want to do this...

I am interested in making this - the angles and fitting are no problem, but how is it mounted to the wall?

Anyone?

I suppose that except for joiner's glue in a butt end (on joints on 45-) there must be connections a «thorn is a slot» for more durable fastening. To the wall comfortably to fasten 2-strange skotchlentoy.

I think its that much because of man hours and such.

I also recommend that instead of making one of these you make 100 and start your own shelf company.....and then post an Instructable about "How to Swim in Money Like Scrooge McDuck".

This is pretty much 2 or 3 bucks worth of 2 by 4 and a few simple cuts. And for $120 a piece you would have profit margins which would put drug dealers to shame.

Oh, that is just too neat. It does look very simple... the only tricky bit would be the corner.

I do hope someone tackles this. :D
