Hi
I used white birch ply boards in various thickness from Bowen's timber. I had to order it in. It was available in 15,12,9, 6 mm sheets. I used various sheets. 12mm for the top, bottom and sides of the drawer carcass. 9mm for the side of the drawers themselves and 6mm for the base.
This stuff was so much nicer than the normal structural ply, but the material was twice the price, but also weighed heaps less and was much higher quality hardly had to sand it.
It worked well, but took a lot of weekends to fabricate.
Tools used were a circular saw with straight edge, plane, chisels, router and drill.
Just heaps of panels to cut and plane to equal sizes.
The picture is them fitted in the back of my Land Rover 130.
I like timber drawers as they are quiet, insulate from the heat, look good, and can be often be fixed up easy if damaged. These probably cost more than aluminium, but if you are building something yourself I always think the savings on labor should be spent on better materials.
Pics on next post.
Most of the where housed, glued and screwed.
Happy to provide more info is desired.
