    It might sound of a bit of daft question but why does the flexy only have three legs? Wouldn't four be better?

    If I can get the 18mm or 20mm rods tomororw I will just built it with three legs then. I will probably mark the rods with a pernement marker where each shelf should go and measure it so it should be pretty easy to get level. I've found a fasteners 12 miles away in Oldham so that should be fun carrying them a load of buses. They will be heavy too.

    Also I found a fasteners 1.5 miles away from me so I will get a taxi back it should cost no more than £5.

    Its three point form a triangle of stability. Uses less material than four legs. Easier to level. Ithink of some more reasons soon.

    with four legs or more, it is almost impossible to avoid rocking because the ground is not perfectly level, one leg being a shade longer, etc.

    Two legs or just one leg will also be perfect to eliminate rocking but unless it is balanced to perfection your precious hifi euipment will fall off :eek:

    This is the basic receipe of what I am doing, if its wrong its too late now as tomorrow at 8:30 the timber merchants will be cutting my MDF

    (6) X 450mm x 65mm x 2mm MDF sheets
    (3) X 18 or 20mm (call this n for now) threaded rods
    (36) x n bolts
    (18) x n rubber washers
    (18) x n metal washers
    (3) x n dome nuts
    (1) x spade drill bit
    Paint

    I just hope nuts are going to be cheap otherwise this going to cost a furtune? This better be better than the £100 rack from RS!

    Costs so far

    Spray paint £5
    MDF £21

    I am guessing rods will be no more £3 each. Nuts are probably about 25p each? Thats still £9, so I am probably looking at £20 for nuts and washers. So the cost will be around £50 which if it all works out it will be fine.

    are you sure? 2mm is a bit on the thin side,i know its called flexi but surley not that flexi, and 65 mm is olny 6 1/2 centermeters (just over 2 1/2 inches)seems a bit narrow
    think ya meen nuts
    go for 6,gives the top a nice finished look
    hope these are just typos or its going to end in tears:D
    think my total bill for 3 meters of 20mm rod,50 nuts and washers and 10 dome nuts cost around £50

    Yeah I meant 20mm thickness of MDF, well thats what I asked for, but I think the nearest they had was 18mm.

    I was simply missing a few vital 0's. Its good job I am not engineer I might get the sack after a few days.

    Its actually

    450mm * 650mm * 18mm.

    I think I need some sleep. Or is my keyboard playing up? Nope its just me.

    Those shelves sound quite big to me, but I guess with the legs going through you need the extra size. All sounds as if you've got it sorted, so good luck! Let us know how it goes, and piccies if you can!

    Better slightly bigger...my kit is an exact fit ! and yes the nuts do intrude, but most full size kit has feet so the nuts and washers go under the boxes. I though I'd allowed enough room !

    bit steep for the MDF aint it?

    B&Q charge £9.98 for a sheet of 18mm MDF that would produce about 6 shelves, and theyll cut it

    Yeah thats what I thought, the problem is I had to get it locally, the only B&Q that will cut it near me is in Stockport, which is 7 miles away. I will have to take them back home in a supermarket shopping trolly. I have not even thought about how I am going to manage these rods, I need to setup a kind of contructiion line, so I get spray one shelve, get one rod, do another shelf get another rod etc. Its a lot of traveling but at least the shelves will be dry.

    If the holes a bigger that the rod won't this cause it to wobble?

    drill yer holes in the wood before painting,otherwise your bound to slip with the drill and end up having to repaint it.o and you can get 12-600x400 shelves out of a b+q £10 sheat of mdf

    I suspect this shop is trying to con me then. I will have a look at some alternative suppliers today. Yep I was going to drill the holes first, but after I get the confirmation that I can get hold of these rods easily.

    Its a pitty my local B&Q didn't stock shelves similar size to what I wanted. They are all to long and narrow.

    Only cetrain B&Q's do it though thats the problem, the nearest one to me that have a cutting service is 7 miles away which I cannot get to. The problem is I am relying on public transport so it is restricitng me some what.

    I've found some rods but they are only 16mm, those these will probably be better than the 12mm I was going to use. They cost £4.10 each though but its a place I can get to quite easily on the bus.

    My grandad said he would take me to this MDF place near me, I phoned round a few other places but it seems they have one price for trade and one of any other random customer. Its just a pitty B&Q wasn't an option.

    On the plus side the nuts are cheap.

    the price you were qouted may not be the rip of it first apears.b+q mdf is bog standard nothing special,however the stuff youve been quoted on may be "A1 construction grade" suitable for flooring,raised platforms ect,it may also have some form of water proofing material added.
