After my earlier two threads on this subject
Sketchup: viewtopic.php?f=34&t=1106
and
Mechanism: viewtopic.php?f=26&t=1095
It was time to knock up a prototype to refine the design and the methods I'd use to make a batch of these things.
I still had a small stash of the Iroko harvested from the Corby school benches (remember those ?)
It is not that nice to use for joints as it splinters easily - maybe as it is old and bone dry.
Anyway I machined up a pile of length of 22 x 65 mm and a smaller amount of 42 x 22 for the door.
The rail and stile frames were made using a shaker profile cutter from Axi (Wealdens would normally be my cutter supplier but they did not do the profile).
All the panels were left open for the prototype but finally will be fielded with 15/16mm veneered mdf apart from the door which will be fitted with beveled glass.
I'd only bought two 500mm lengths of the brass angle so the runner mechanism is shorter than the final version but it proves the function. You might notice odd rebates that are longer than needed and the odd other "refinement" but this was the whole purpose of making a prototype.
The design consists of 4 panels, top bottom and two ends connected with half blind dovetails. In the final version veneered mdf will form a captive back. This is omitted here for access to the mechanism etc.
Door fully open:
Door closing:
Door fully closed:
The position of the pivot is designed that when the glass is fitted (weight about 2.5kg) it will hang vertically rather than gape slightly open as in the photo.
Im not sure if I have the rails and stiles the "right way round" for the door.
Option 1 as it currently is:
option 2: where it would be similar to the corner of the fixed frame:
I'd value your opinions please especially those who have some artistic flair ( unlike myself!)
Cheers
Bob
