After a number of failed attempts on the table saw to match the angles perfectly, I realized I could make the cuts simpler and more accurate with the track saw, and so I set the angle at 10 degrees for each piece, with the blade tilted at 1.5 degrees (which was needed to keep the shape square).
I still do not fully understand why, but more about that in the final chapter.
Next I set the fingers on the jig and marked the center and proceeded to cut the pins.
With a 24” jig, the high end of the cradle almost used the whole space I had available, and made use of each set of fingers.
The tails are cut the same way, except you need to angle the board 1.5 degrees away from the jig.
Don’t fully understand that either, except that when I did not do it, I could not make the joint fit tightly, and it was not square, more later on that.
To accomplish that bevel while in the jig, I made up some plywood angled jaws to hold the piece in place which fit over the jig clamps.
And I thought this would be straight forward…
Refining the shape of the sides after the dovetails are cut.
And trial fitting to see where the head and foot should meet and shape those pieces.
In my rush to get this done, I realized after the trial assembly of the sides, that the floating panel would not really work for the bottom, as the bottom had to support the rockers.
The design changed once again and I decided to mount a breadboard style flat panel base to the bottom of the cradle after it was glued up, then dovetail the rockers into it.
I glued up a panel and cut a slot in the breadboard end and panel for a spline. Then cut the spine apart to allow screws to fasten the end to the panel. Only the center piece of the spline is glued to the panel and end, others pieces are glued to the panel, but left floating on the end.
Next I flattened the panel and prepared to rout the dovetail for the rockers.
Now to dovetail one side of each rocker blank so I have something square to work from, and test the fit.
Rockers are made from 5/4 tigerwood.
