Hello and welcome. Today i have started building caterpillar D9R. Since there is no kit avaliable (or i don't know about it) i have bought small toy at Toys'r'us, about 1:50, 1:52 scale and i will use it as a base for scratchbuild. I can estimate that i can get about 85%,90% accurate, but it still won't be perfect. I will have to use a lot of styrene sheets and even more putty.
Ok here we go:

Wasn't Cromwell Models working on a D9?

Good luck
A very motivated start!

Hello i have made a bit progress, everything will look much better when i will cover it with a base paint. The easy part is done, now the hard one.

Hi Adam
You migt want to have a look at the build my late dad (BARV) done about 2 years ago,
1/35th scale scratchbuild.

Not something for the faint hearted.

This is so cool mate, to scratchbuild this beast from plans only is very impressive. I have put my toy "update" on hold so far, i have mentally died after trying to build proper tracks.

Steve,
Hello Steve Jr. Yes this is one build executed by the MASTER!! Hands down. We traded info on this beast before his passing. Todd

I can't see your pictures.
As I know there is a copy in resin already avaiable and cost more than 100 euro.
In any case I also built a 1:35 D9N following the great Barv
and I started to scratch build a D9R if you like you can see some pictures below.
