Thanks again for your thoughts, guys.
Just when I thought I'd put this design to bed, you've got me loading up SketchUp again... :roll:
As far as the runners go, I've decided to go with JonnyD's idea on having one central runner with a strip that runs in a slot housed in to the underside of the muntin. I'll probably use beech for these two parts (I have plenty of it!!
). What I like about this is that it'll save the cost of new timber and save me a little work. I won't need any side runners either, except on the bottom drawer.
To be honest, I keep looking at my drawings and something doesn't look right...
I can't decided whether I need to try and squeeze a top rail on to the front or, as you guys keep saying, it's the drawer rails (or, lack of!)... I will raise this one with Pete again. We've have agreed on a slight graduation to the drawer sizes as well. It's subtle. Not as clear cut as the Hambridge method but, it does make a difference.
