I have some pictures of the D7 both still and in action in my MSN group
about bulldozers. (http://groups.msn.com/WelcometoPuffie40/home.htm)
a picture on the first model I tried to build is in my brickshelf gallery.
(http://www.brickshelf.com/cgi-bin/gallery.cgi?m=puffie40) (Folder name is
CatD7)
I have not taken any pictures of the second one yet...
I have both the parts and service manual for the D7, And I could use this as
reference for parts not readily visible on the machine.
Realistically, I would just like a stand-still model, no "Bells and wistles"
:-) (Though I am not sure how I would make the cyilenders) I would just like
a bulldozer with moving tracks, pivoting trackframes and a blade that moves
up-down. I'll worry about motorized funtionality later.
The main problem I have is the front. On the real model, the rad is rounded
somewhat on the top and both sides. I am trying to replicate that, but I
don't have much of a "Mental parts list"(Being able to know part shapes and
how to use them) The first model does not show that
Seconed problem area is the frame, Which I want to be fairly solid, but
realistic enough.
I am making the scale fairly big (To get a picture on things, I am using
40-tooth gears for the sprocket and idler)
I am making the model on MLCad.
I am wondering if I am asking too much from lego...;-)
Also, I will take pictures of the seconed model this afternoon, and post it
in the brickshelf gallery.
Thanks!
