Gallery-17 - Duesenberg


The last of the trio, the 1933 Murphy Boat Tailed Speedster

‘J’ Duesenberg, for me a very classic Duesenberg design. 

The engine and chassis follow my normal practice, as above

described, it being on a standard long wheel base chassis

with unsupercharged engine and internal exhaust system

with an 8 into one exhaust pipe header.


The main  body parts were formed in  brass and copper sheet

over hard wood formers, as were the fenders, following

normal practice.  The aluminium parts were then formed

over these, to make a very tight and close fit.  When

completed there were epoxy resined in place onto the cleaned

copper and brass sheet body panels.  The finish being provided

with a fine wire-wool - bright scratch finish, rather than a polished

finish.  This blended will with the highly polished chromed parts.

The rumble seat is hinged as on the car to open to a comfortable position, then fold flat to the out side shape.  A spring loaded catch holds it in place, so that a slight pressure on the rear half will open it.  Full size practice would be to open with a key.  A side door on the right side, was to provide access for a set of golf clubs, there is no trunk as such.  The top when folded would be located under the panel to the rear of the seats, and is completely hidden like that at the Rollston Convertible Victoria.


The running boards presented considerable more work than with other Duesenberg models, as the chromed strips had to be made individually, rather than machined as part of the whole.  The brass block first had milled to the top surface a slight recess, to take a veneer of a fine grained hard wood - pear wood in this case, mahogany in full size  practice. The corners were squared out sharp for a rectangle for the veneer, which was then taped in place and drilled with the aid of a simple drill jig.  Easier to mark out a drill jig once then use it for both sides, rather than mark out the two side individually.  The individual strips of brass were machined as a long length, then cut to the required size, and trimmed to match the originals.  the chrome is in fact just a surround for a black rubber foot pad/step, so these had to be masked out after the chroming to simulate the mat flat black rubber of the pads.  Each machines strip, after cutting and shaping, was drilled to take two small pins, which later were used to attached the strip to the plating wire, then to locate the strip on the running board, in the final assembly.

For those looking for more information on the construction of the Falls of Clyde, I am running a ‘Log’ on the building of it on the ‘Model Ship World’ web site.


Check out < http://modelshipworld.com > and search for ‘Falls of Clyde’


Most of the photos will  be the same as here, but there will I hope be more insight into the actual working of the materials and building of the model.


Four photos are added at the start of each month and relevant text on the building.  It should be running for a considerable time to come, and hopefully will not repeat what I have here too much.
