3D Model Complete
I feel that the 3D model of the Offenhauser 97 cu in. Mighty Midget is complete enough to take it to the next stage and start building the prototype. Including the hardware, there are 86 different part types in the model and over 300 individual parts.
I have 3D printed a few of the major components to get a sense of scale.
The gear tower is pretty small and has very intricate details.
I am going to machine the crankcase top first. Working on the mill, I square up the work piece and drill 4 holes as entry points for the 1/4" flat end mill that will rough out most of the inside material.
I create the tool paths in Fusion 360 then output G-code for the LinuxCNC router.
Then I start making chips.
I believe that this will wrap up this thread in the "Plans" section. I will start a new thread in the "Work in Progress" area to document the machining of the prototype. As I build the prototype, I will be feeding back what I learn into the 3D model and the drawings.
