Here you can see my drawer box dry fitted, the internal corner with exposed dovetail joinery, hand-cut of course.
And the finished drawer on Accuride runners, one fitted to the side as normal, the other fitted to the bottom of the drawer bottom. When fully extended there is a bit of play, so I'm going to fit another runner to the bottom.
Here you can see the under-mounted drawer runner, there is enough room to place another to the right of the existing.
I did think about having a normal drawer, and letting the drawer front sail over. But thought that that was a bit of a cop out, and decided on this course of action. As it turned out it only took perhaps a couple of hours longer, and the clients have an extra 1.5 cubic foot(approx) of storage. They also have some funky dovetails to look at when they open the drawer.
The drawer fronts on this wardrobe are joined together with a piece of face frame stock in the middle, this will look the same as the other wardrobe except for having two large drawers instead of four.
There is still a bit of cleaning up to do on these drawers and to make the bottom drawer front also, but they are more or less finished, thanks for looking.
