Debugging completed, wood sub base surround finished, final
photography and videography finished, NAWCC Zoom presentation. October
The wood sub base surround is finished, the eleven case glass
keyways are delivered. In recognition of the completion of the project two
detailed video montages as well as photos for future articles in the NAWCC
Bulletin are included in this
installment. The front and rear cover issue of the September Horological
Journal featured an eight page article, and an additional three-part
series is being published in the Bulletin beginning with the current
November/December issue and explores what has been documented since the last
article that appeared in the March/April 2017 issue.
The glass keyways are completed from the case maker. These details will be
sent to Buchanan for the cutting of the holes in the case glass. We are
looking into museum type low UV and anti-reflective glass for the case.
A fly cutter on the mill is used to cut the brass stringers to produce a
rounded edge, next an over view of the mill.
The fabricated brass stringer stock. Next photo, the stock cut to size with
corners cut to 45
° angles and screw holes, ready for lacquering.
In the first photo the brass stock is being fitted to the flame
mahogany bases underside. Each part is carefully numbered for assembly. This
is another example of Buchanan's attention to detail, in case these parts
ever have to be disassembled. These same methods are used for the
fabrication of brass casework.
The brass stringers are now installed, first photo. Next a close up
detail of the front sub base.
The completed wood sub base.
The aluminum carrying structure also known as the 'sedan chair' attaches to
the lower movement frame for moving. In this photo it is used for a
simple short distance move from one table to the turntable. In reality the
real purpose of this device will be for the moving of the machine after
delivery to its final table. In that case all of the dial work,
(complications) and well as the pendulums, escapement and bells will be
removed so only the machine base and the three main movement modules will be
assembled for a total weight of about 110 lbs. The clock will come in at
about 140-150 lbs when fully assembled.
Buchanan now makes a turntable for the final photos for this installment and
the NAWCC article publications.
The September 2021 issue of the Horological Journal
featured an eight page article on the completion of the project.
