1/25 scale AMT Caterpillar D8H build


Recommended Posts

Hey guys 

  Here are some pictures of the Cat D8H I'm doing on Unigraphics NX11.  I have access to  UG while my wife is working at home for FCA (Chrysler). So I've been working on the computer instead of my work bench and I'm trying to get everything done before she has to go back to work at the Tech Center. So here they are.

Hey guys 

 I found this model on the internet. It's a Cat D11!...BiiiG... It's a pretty good model, just needed some tweaking here and there. I had to replace the crappie simple tracks that it had. So I  took my D8H tracks and up sized them to fit, now it looks proper. It actually has the engine modeled up in it. But it's just a sheet body not a real solid model, so I'm not sure if I can print it, we'll see. So here are some pictures for you to look at.

20200916_192056.jpgshe is definitely a BIG MOTHER! But it does fit on the 4 axle drop nose lowboy trailer, barely.

Hey all 

  I've been working on the D8H Cad model some more. I have the D352 engine just about done, still have a few large items to do plus all the plumbing. I have the blade and the blade arms almost complete, still need to do the blade tilt cylinder and the plumbing. Here are some pictures for you to look at.

  Here are some update pictures of the Cat D8H. Jeff you wanted a R.O.P.S. and here it is, it still needs the attachment brackets and hardware. I added the Cat logos and lettering to the sides, front and rear.

Excellent !  (Although, given the size of your truck and trailer, I’d have said the D-11 was more appropriate to fill the flat bed ;))

Hey  Hubert 

 Actually the D8H just barely fits on the 3 axle trailer with the rippers on it. I'll post some pictures of it on the trailer tomorrow.
