Resin print of Standard C80P trucks

They arrived quicker than expected. This is how they are coming out of the shipping box, printed by i.materialise. The quality exceeds largely my expectations.

Tenshodo SPUD measures and drawing

The Tenshodo "SPUD" WB24.5 motor bogie is a good base for heavy interurban models. With its wheelbase of 24,5 mm, it matches totally for 7' trucks with 36" (or 37") wheels.

This bogie is a little speedy, but with a good controller and some ballast it will work well.

His low construction permits a virtually unlimited rotation of the truck under the car.

But Tenshodo don't deliver a blueprint with this truck, so I needed to draw it of my own.

You can download a pdf sheet of the measures here.

I made 2 versions : First the real H0 scaled version with the real measures of the model  in Millimeters and then a version in scale 1:72.

I made all my bi-dimensional drawings in 1:72 scale, because it is easy to handle a scale of 1 computer point to 1 inch.

As 3D drawings has no scale, I made even a 3D blow up of the Tenshodo SPUD for virtual 1:1 scale.

Now, it's up to finish the truck side frames, and to think about a car body to put on.
