Need some quick help from someone a bit smarterer than me.

If you go ball bearing runners, yea not so much needed.
If you go nylon you need to For the draws to counter lever Off of.
I'd still add the one down the guts as it makes it easier to screw your sheets down. It's much easier to work in halves than to try get the top in 1.

But 12 mm is odles. 12mm ply has a braking strain of some 250kg over the 2.4 length, so spanning 600mm, it'll never brake, it just added weight..

My larger runners cost me $88 wholesale... the retail was a killer but they can handle nearly 2 of me sitting in them if the bottoms of the draws were strong enough.

I ordered some 100kg rated 800mm and 700mm off eBay

Also, when you build the drawers, have the ends sit inside the sides, as this will mean you are less likely to rip the front off

Hi, with my fridge slide and drawers, I used slides from Ovesco.com.au, they have an online catalogue which is very helpful, I used 45kg slides on the draws and 125kg slide on the fridge slide. As to length 800and 700mm will do fine. They are a great company to deal with, I have no connection with them other than a satisfied customer
Regards Burto

I have read lots of good things about them. I ordered some stainless T handles from them.

He means have the ends sit inside the box. But by doing this you will have the draw runner gaps.. I've had no issues with them in the end and you can flush it all in and look professionally done..

Also as you have used runners you might want to incorporat locks to hold the draws in place.
Father in-law used a simple cam lock and cut a slot into the front top support.
I'll try get some pics of it for you..

I think I get ya now... how would that make it more likely to rip the fronts off?

I'm using locks like this.

I think he means to rebate the end pieces into the sides, if it were the other way around it would be easier to break the ends off.
