Help with design of large TV cabinet
Hi All,
I hope you are well. I am busy designing and building the below TV unit. The carcass as well as main dividing shelf in the middle will be constructed out of 22mm A.White Oak and all drawers out of 16mm oak veneered chipboard (Particle Board). Currently the unit measures 2100(L) x 450mm(W) x 450(H). The middle shelf will be supported by a dado joint and glued in place, while the body of the unit will be biscuit jointed, glued and pocket joined.
I have a concern that over time the unit may sag in middle, with no support in the cavity underneath the drawers. There is a hidden space as shown in the middle of the cabinet to house electronics where there is a box frame which support and joins the top with the middle shelf which should provide some support.
Am I being silly in thinking that this may sag over time?

Some additional support\bracing
Hi Everyone,
Thanks to everyone who has commented thus far, all comments have been very useful.
@auscab>> Your comments regarding the french cleat intrigued me and I realised I'll need to support that top in some way, so, see below images attached...I have placed a 22mm x 50mm stretcher (MARKED "A" + "B") front and back of the top shelf which will be glued and screwed across it's length as well as width joining it to the sides of the cabinet.
Additionally, I have placed a stretcher of the same dimensions (MARKED "C") underneath the middle shelf\divider just behind the midpoint so as to minimise the chance that it can be seen unless you really want to.
Thoughts from those are assisting me on this one?
Once again, thank You for the responses and assistance on this one :-)

So, I've reworked the entire design...
Hey Everyone...
Gave it some thought, seems it may have been flawed completely, attached redesigned unit below.
It now consists of 3 independent carcasses that will house two sets of drawers on either side, and then the centre carcass for the electronics etc. These will be tied together with screws to join them, as well as fixed to both top, side and bottom panels. It does add more weight, however, overall I think it increases the load distribution a lot more. All carcasses will be made using 16mm oak veneered chipboard, a 10mm backing will still be used to add additional rigidity too.
Any thoughts, suggestions, kicks in the ass etc encouraged :-P
Appreciate everyones help on this one.
