The other end of the same supports are dovetailed:
My match marks might be a little on the quirky side.
Later on, after milling the dadoes, I had a chance to check the fit of one of the drawer runners to one of the main vertical support boards:
This is just what I wanted at this stage - a close 'light interference' fit which can be eased very slightly later on. Just a shaving away, that sort of thing.
The horizontals - the rails- are pretty much complete:
Another view - the spear point miter remain long at this stage:
The spear points are about 1/16" (1.5mm) long at this point. Fitting spear point miter joints requires a cautious approach I have found. You can creep up on your lines, cut by cut, but things can take a bad turn if you go beyond those lines. It's the sort of work I now find suited to aid with an Optivisor, put it that way.
Test fitting the rear rails to the vertical dividers, the connections involve pairs of simple half lap joints:
A little closer look:
This joint is about halfway from the fully closed position, and seems to be going together without undue complaint. There is very little 'crushability' with bubinga.
A view from the other side shows the open mortise on the rail to accept the runner support piece's tenon:
The other set:
I know from measuring the parts that these joints for the rear rails should close right up, and they're feeling about right so far, so no point smacking them all the way down with the mallet just yet.
The wider boards which serve as vertical dividers will need some further mortising yet, however they are getting there. The bottom of these boards will have multiple tenons, while the top end will feature a stepped arrangement of sliding dovetails.
All for today- have yourself the best possible weekend! On top post 38.
