Re: Cat 777D Mining Truck
I think Google sketchup is free, and know a few people that have used it. It's not a high dollar program but it can get things further ahead than napkin sketches.
Good luck in your recovery, hope...

Re: New Bucket for the CAT

Re: cnc ?
Not sure you can add live tooling to a Romi lathe, but have seen Darex auto indexing turrets on them. For starters though a good Aloris QC toolpost is about all you need, and a paint pen to number...

Re: Cat 777D Mining Truck
Looking good. I see the cutouts for the steering arms now as well, that clears it up. Can't wait to see more progress pics.

Re: Cat 777D Mining Truck
It's looking really good! I love the motor setup.
I have to ask, maybe I'm missing something. How will it steer? I mean it looks like the steering arms will hit the frame rails when it turns?
