1904 OLDSMOBILE RUNABOUT 1:12 scale

To all,

Since I am building the Runabout version first, and to keep it separate from the Delivery Wagon, I started a different thread.

Here are some pictures of the frame assembly.

Thanks Ringmaster! There are some really great frame-worthy pictures on that site.

Today, I worked on the leaf springs. The pictures speak for themselves; I just want to point out that the yellow spring-profile templates are important to use during the assembly of the springs to ensure that the car sits at the correct height, and that all 4 wheels touch the ground. The last few pictures show the frame and springs glued together and edge-painted flat black.

The Flywheel was probably the heaviest single component of this car. The reason for the mass in the flywheel was to allow a smoother effort when turning the start crank (which could be started from the seat), and also allows the car to transition from a dead stop to moving in a less jerky fashion.

The model is designed so that the live axle (white coat hanger wire in this case) can be slid out from the side of the frame rail, and the flywheel, planet gear assembly, clutch and drive chain can be removed. You will see why that's important later on when the rear axle is installed.

The engine crankcase and cylinder doesn't resemble anything like today's internal combustion engine. The first picture shows a breakdown of the "actual" basic engine. The remaining 2 pics show the start of my version of this strange-looking contraption.

I would love to take a time-travel vacation back to 1904 just for a week! I could become an overnight genius just by suggesting to add a "choke" to the carburetor! Once I gained everyone's attention, I could then start making ridiculous claims; like brazingly suggesting that one could start the engine using an electric motor and a battery, or by adding brakes on all 4 wheels by applying the concept of "hydraulic pressure".

hehehe you could realy blow there minds if you told them about four wheel drive, and four wheel independent suspension. Not to mention
AC, anti- lock disk breaks, and Hemi engines.

Interesting: in that illustration of the engine, it looks like the carburetor IS the cylinder head. Beautiful so far!

They'd hang you. I am so impressed by your ability to extrapolate such a fine model from the drawings you have, envious actually, but in a good way. Brilliant!

The weekend is finally here!

Tonight, I added more detail to the engine block (if you want to call it a block). I still need to add the compression head assembly, and a little edge-coloring, and the engine will be placed in the frame permanently.

Tomorrow, I will be putting the rear axle together. This will include the drive chain and final installation of the engine and flywheel.

This is just looking excellent!
