The task of this cabinet is to support the center front of St Patrick Cathedral model. I will make it so that the center of the model will pull out 24” to view the interior details.
This cabinet will be 22” wide and 32” deep. There will be an internal frame attached to cabinet 7, to support the sliding assembly for the cabinet.
This shows the complete fixed portion of the cabinet. It will be the main support for the shell.
This is the complete frame for the outer shell to be attached later.
Here is the cabinet frame in the extended position.
You will see that on the right side there is a cabinet, this is part of the assembly. The LH side is not in position as of now.
This side view shows the full extension of the assembly
Notice the two support blocks located towards the upper right.
The support blocks will be under tension in the lower position (not shown)
They will rotate up when the cabinet is moved 3/4 of the way. They will then be in position as shown.
In this position it will support the model base. This base is not on top of this cabinet it is 22” removed to the back. This cabinet is larger than the model, so there is a cantilevered table top that will slide and rest on these blocks. The weight of the supported model above these block is 65 lbs.
Here is the assembly of the support blocks, tension springs, shaft, and mounting hardware.
Once the frame was complete I added the raised panels styles and rails, added lower trim, added walnut rail and picture frame.
I sized and fasioned the support post and raised panels to have a uniform flow in the closed position.
And in the open position I also have the rear support post matching when in position. This detail is not neccessary but why not size and position geometry to have meaning.
This shows half the table top in position to give you an idea of how the support blocks will preform when activate
Between the white plastic strips is a wire chase. This will be used to support all the electrical cables to the model. Harnesses will be supported when the table moves.
There are several lights to be added in the future. There are 2 internal wire takeup reals that will coil and uncoil wires etc.
The staining of the walnut has me stumped. I might post for suggestions as to go dark or natural stain, or no stain. Thanks for viewing.
