What wood for bookcases

Post by nicknoxx » Thu Nov 15, 2012 3:56 pm

Hi All

I'm planning to make a wall to wall bookcase which will be painted but I'm not sure what wood to use for the construction. Obviously needs to be cost effective but most important is the shelves don't sag. The span of the shelves on the right hand side is 820mm but the span over the doorway is 138mm. It may be possible to put an extra support in the middle of that span if necessary. Any suggestions? (and yes, there is a gurt big RSJ in the middle of the room)

Thanks
Nick

If you want a grainless surface beech, if you want it to look like painted wood then ash (if you can get it). Both are cheap and take finish well.

That span over the doorway looks quite long though so check the movement you might get with the sagulator.

if you are painting it, why not use MR MDF?

If you want a grain to show through the paint then use veneered MDF

Don't use MDF, at least not for the shelves, it will sag.

Would 25mm sag do you reckon?

I think you'd be ok if you fixed them from behind, but not if they are on pegs.

I use MDF on pins but i always lip the front with solid timber if they are going to take things like books or over about 600 -700 mm .

There's SketchUp trap where you end up tying to make something complicated basically because you can't make SU work for you. Try a pencil.
NB real wood is 100% or more better than mdf esp for shelves.

If it`s going to be painted it may as well be MDF or veneered MDF if you want the grain to show through.

I`d just put a vertical central support in the middle of the section of shelves above the doors, this would cut the shelves down to under 700mm, could be fixed from the back & wont be noticed when full of books.

What ever you do they wont support that RSJ........for long

Was that tongue-in-cheek, Nick, or is ash that difficult to get hold of?

I'm guessing that as there is a ban on moving the stuff around, it is going to get rather scarce rather quickly. Not that I've tried recently.

I thought most ash came from the US which isn't affected.......

Do you think the govt is clever enough to know that. Rushed legislation and all that...

I think you'll find that the movement restriction applies to live trees and possibly green timber. Anyway, virtually all of the ash timber on sale in the UK has been imported, primarily from the US in sawn and kiln dried form. Therefore no risk or shortage.

Indeed the saw mill man who I bought this stash of ash from yesterday is expecting a bit of a glut of native stuff.
