Thank you Dan and Clayton.
Today its time to see the start of the chassis with the modifications.
The first important thing, is to get the double drive axle in the right place, this was a bit of comparising on the basis of the st Joseph Motor Line picture.
Afterall, the double drive fits about 1,5 times between the front axle and the first rear axle.
On the ATM chassis it means that the double drive need to be 3,5 cm moved to the front.
Than remove the plastic axle clips and drill the right axles through and through.
Then replace these plastic axle clips with a brass tube, so that the model is always straight on its wheels and you don't have the risk that on later term a shaft bends or breaks off.
I'll do this to all of my truck models.
The chrome rear wheelrims are de-chromed with oven cleaner, because i will paint them later in a white colour.
The next job is to make the front axle steerable.
First i drill the holes in the weelhubs, than cutting and replace them with brass pinns.
After this one i remove the engine supports in the frame, because the papa truck has a V8 engine, and the marmon is getting a Cummins 6 in line engine.
This engine fits good under the cab and does not extend behind the cab.
Then place the engine and shortened drive shaft between the chassis, together with the rubber tires from the kit , to see the proportions.
Below I show the difference between the tires, in front the low profile tire and on the rear the normal tires.
At last but not least, the bumper.
Above the resin bumper and below the styrene bumper.
For the radiator I have to check whether the radiator of the Peterbilt is a better choice, because of the height.....im not really sure.
To be continued.
Hermann.
