Old school Cat D8H

[bobmorey]

Hello All,
This is my first post on this site. Lots of cool projects here.

I've wanted a CAT dozer since I was little kid. So I'm going to make one that is RC. I like the old school D8 and D9, before the high drive came along. Not that the newer design aren't awesome - I just like the look of the old D9H and G.

I bought this model on ebay as a reference. Its the 1/25 ERTL/AMT Cat D8H.





Not sure on scale of my model, I like 1/16 and 1/6 tanks, but a dozer in 1/6 would be huge. Perhaps 1/14 to be used with Tamiya trucks? Depends a bit what motors I can find. I'd like to make it hydraulic as well for blade lift although this will be my first venture with that.

I will be using Autodesk Inventor to design the model. Its similar to Fusion 360 and from Autodesk.

I will start on tracks and drivetrain first, as this the hardest part. I have CNC mill and manual lathe to make the parts. The model will be mostly aluminum, but perhaps steel tracks.

So not much to show until I get the plastic model to design from.

Till next time..
Bob
