           case design1.jpg (486589 bytes) This was one of two designs considered. While this is a beautiful alternative, it did involve a larger 'footprint' on floor space. But moreover, it is nearly identical to a design for a case that will be built for my next commission from Buchanan, a very large and complex astronomical skeleton clock. A brief presentation of the design concept for this clock can be seen here: http://www.my-time-machines.net/Presentation_paper_final_web.pdf

 

           case design2a.jpg (474852 bytes) A simpler design was chosen for this clock.
Brass tower clock-Saff (31).jpg (642639 bytes) Shown here is the mockup for the stand and glass case. A change was made where the the glass case has a taper to match the the slant of the case legs instead of having straight, parallel sides,
           Brass tower clock-Saff (83).jpg (344801 bytes) Completed stand and case. The material is a heavy and densly grained wood called Afromosia. There are a set of three rollers hidden behind the front skirt to align and center the three weights. Click on the photo to see more of it's construction.
Brass tower clock-Saff (60).jpg (44414 bytes) Toward the end of the project I decided that I wanted a winding jack constructed. This would minimize the effort and potential for a disastrous tipping of the stand when winding the heavy 70+ lb. weights without any reduction gearing. We achieved a 9:1 ratio to make for a comfortable 8.25 lb. weight at the winding. Click on the photo to see more of it's construction.
