I worked on the drawers and drawer case on 4/9/2011.
The drawer case has to be the same width as the rest of the main frame boxes, which is 15”, and the same length. I’d originally planned to do 24” but after getting the drawer slide hardware I decided to add a bit of a gap between the backs of the drawers so added another 1/4”. The frame boxes will all be 24-1/4”.
I chose some full extension 12” drawer slides (Shop Fox D3028, 100 lb. capacity side mount, $8.55 per pair, from Amazon, with free shipping since I bought 2 pair and a Arsenal 5700 shop apron the same purchase). They are 1/2” thick each, so the width of the drawers then comes to 12-1/2” (outside dimension).
Here’s the exploded drawing of the drawers, and I even took time to do the box joints:
And here’s the drawer parts:
I haven’t built drawers before and I can see that the fit can be an issue. I may need some shims between the drawer slides and the pieces somewhere if things aren’t accurate.
I used a box joint for the drawer backs. I’m not putting on a separate drawer face so I used a french dovetail joint to attach the sides to the drawer front. I think this should be pretty sturdy.
My original drawing separate pieces for the drawer case and the tray above the drawers but I had some 7” wide pine on hand so decided to use it for the sides. That gives me a single piece which should improve stability and rigidity in the frame.
I had decided to use box joints for all the frame boxes, this one included. This wasn’t too bad to only put the box joint on the top part, 1/2 way down, for the tray above the drawers. I only screwed up one cut, doing the box joint cuts all the way down the edge. Another reason to do a prototype!
In these pictures I haven’t done the dado yet for the plywood drawer bottoms or the tray bottom / drawer cover, nor have I mounted the slides yet, but here are the parts all together now:
After getting these done and submitting them for my wife’s review and approval (I tend to show her every thing at each step – proving I’ve done something with the tools and haven’t inflicted any serious self injury), she wants deeper drawers in the “real” version.
