A friend sent me this link : http://www.craftsman....com/chenot.htm
but I cannot crack including the photographs. However, they are all on the link.

A miniature functioning replica 1932 Duesenberg by Louis Chenot, a beautifully
constructed 35" long working model made in 1/6 scale.
Louis Chenot has spent the past ten years building this incredibly
detailed 1932 SJ Duesenberg LaGrande dual-cowl phaeton.
Not only does it look good, but the engine runs, the lights work,
the top mechanism functions and the transmission and driveline
are complete. Lou started his research on this project over fifty
years ago with the purchase of a book and through the following
years collected many drawings and studied a number of
Duesenberg's while they were being restored, taking photos and
recording dimensions.

Here's a shot of the finished car from the side on its specially
made display table. The model weighs about 60 pounds.
Lou's 40 year career was spent as a mechanical engineer.
In the 1960's he spent 7 years restoring a vintage 1930 Cadillac
convertible that was on the show circuit for years, but now he
prefers to work on smaller projects in the comfort of his home shop.

The bodywork is all metal, not fibreglass. Here is the car in
Lou's shop before the brass coach work was primed or painted.
Lou is not adverse to remaking a part that doesn't meet his
standards. He started over on the especially difficult brass
radiator shell nine times.

Here is the engine removed from the model and sitting on its
test stand. The transmission is in the foreground.
Most running models are built at larger scales like 1/3 or 1/4.
Working in the smaller 1/6 scale magnifies the problems caused by miniaturizing certain parts.
Remember that these scale parts are 1/6 as long, 1/6 as high and 1/6 as deep as real parts,
making them 1/6 x 1/6 x 1/6 or 1/216th the volume of the original part.
By comparison, a 1/3 scale model is 1/27th the volume and a 1/4 scale
model is 1/64th the volume. Further complicating the prospect of
building a running engine at that size is the fact that fuel molecules
and electricity don't scale. It is very difficult to get tiny carburetors
and little spark plugs to work like the big ones. A video of Lou
starting and running the engine for the first time can be seen at


Inside the straight eight engine are all the correct parts custom
machined to scale from steel, cast iron and aluminum. Here we
see the block and crankshaft at the top. Arrayed below the block
are the cast iron cylinder sleeves, pistons, wrist pins and
assembled connecting rods.

Even though there would be no way to tell once it is all assembled
the cylinder head shows that Lou didn't cheat. The engine has
4 valves per cylinder--32 total--just like the real one.

Here is the head (before painting) with the camshafts in placeĀ¬
there are 16 lobes on each shaft. (The apparent curve of the
upper shaft is caused by the camera's wide angle lens.)

The gears inside the differential will never be seen by anyone,
but Lou cut them as actual hypoid gears like the real one rather
than machining simpler bevel gears.

This is the dashboard and interior with the body primed but
not yet painted. Note the detailed instruments and engine-turned
finish on the dash.

The complicated convertible top mechanism is shown in the
lowered position before the canvas top material was installed.

Lou was presented with a special Lifetime Achievement award
by the http://www.craftsmanshipmuseum.com/in 2009. The
model was nearing completion but the engine had not yet run.
Now that the engine runs and the model is completed, Lou has
been selected as the foundation's "Metalworking Craftsman
of the Year." The award includes an engraved award medallion
and a check for $2000.00. Lou is the 15th person to receive this
coveted annual award. Because it is likely that this could well
be the finest running model car ever built in this small a scale,
Lou's award this year will be presented as the "Craftsman of
the Decade." More can be seen on this car and some of Lou's
other projects athttp ://www.craftsmanshipmuseum.com/chenot.htm
