CAT D11 bulldozer 06-21-15 update


Recommended Posts

The record snowfall has been preventing me from using my spray booth. Not being able to prime and check the sanded parts is a real pain.

 

New front and rear idler wheels have been fabricated. The fronts are 1-1/2” CPVC, cut to 17 scale inches wide, the rears are 1-1/4” CPVC, cut to 17 scale inches wide. All wheels are wrapped with (2) .020” X .250” styrene strips. .080 styrene is used for all centers:

The inner radius was made with Bondo glazing and spot putty:

Here’s a quick mock-up:

Modifications to the undercarriage have been made (not completed):

Here’s some pics of the blade before any modifications:

The inside of the blade has been re-lined with .030” styrene to achieve a radius, and scored on the back and bent to simulate original:

After the addition of the wear plates at the base of the blade, a piece of .015” styrene was installed above them and will be blended in:

Well it’s been about a month since the last post. I’ve managed to get a few things done. I purchased these at the local CAT dealer:

A coat of CAT yellow primer was applied and new track rollers and supports have been fabricated:

That's just fantastic work Dennis . Will it be brand new or used and abused ?

Thanks Dave. I'm not sure if I'll keep looking new or used. Definitely not abused...I've put too much time into this build to beat it up :lol:
