Here is the 1931 gasoline powered Caterpillar Sixty track tractor, last year the gasoline powered model was made. By this time it had 72 brake horsepower and could pull a little over 6 tons. It was used for everything from AG to construction to shunting rail cars and just about everything in between. The 1/220 scale kit includes two tractor bodies, two sets of track frames, two seats and two sets of seat cushions, two clutch controls, two exhaust manifolds, two optional front fender/radiator guards and one optional corrugated metal canopy. Kit also has detailed undercarriage and detailed exposed engine, rear hitch and front hook. You can find this model here: http://www.shapeways.com/model/1933257/cat-sixty-tractor-set05-01-14.html?materialId=61 Thanks, -Jon
Glad you guys like it. Rust? Oh no... I cant do that... As a heavy equipment designer and a life long fascination with all things heavy equipment, both historical and new, I could never do that... It would be like asking a Porsche designer to paint a 911 rust color. You just dont paint your own baby rust color... But I have absolutely no problems what people paint their babies or Porsche 911's... In fact, if anyone bought this thing, I'd love to see it all in rust ......
Is there any chance of getting this file to edit and print in HO? You contact me off list at nvrr49 AT yahoo DOT com Obviously great job!
Hi Kent, I use ProEngineer and works off of whats called parametrics. That means all the features made to create the model are related to each other. I also use whats called the master model technique. That means I built the entire tractor as one part out of many individual closed loop surfaces. I then export out these parts as separate individual parts. That being said this model has 789 features. Scaling is no problem. But if one of the 789 features fails during regeneration after scaling, it can get really, really ugly real fast. And if I export it as an iges or step file (to eliminate all the features) and then scale it and the model fails, there is no way to fix it. But I'm willing to give it a try. But before I do, keep in mind I have pushed the limits of FUD in 1/220 scale so some stuff might look over sized in HO scale like the controls and some of the engine detail and canopy pillars and so on. It might end up looking more like a toy... Model might be a bit pricy in FUD but at least you'll have other options to choose from for materials in the larger scale. So let me know if your still interested. Thanks, -Jon
Does not sound like a good risk versus gain proposition. If it was done in an SKP file, I could size and edit it, but such is life. Thanks for the ProEngineer edification.
