Hi everyone, I've been tossing around the idea of building a articulating dump truck for some time. So this winter I thought i would give it a try. Now this will not be close to some of the amazing builds that are on this site. This will be more a cut, weld, kinda build. Ive got ton of inspiration from andyathome rock truck build. It won't be modeled after any particular truck but I do have a small toy one from my earlier years that I've been using for reference. Here's a picture of it. .
So i started with some half inch square tubing i had kicking around from a boat trailer build.
I'm gonna run 6 25rpm geared motors.

Rims and tires I'm gonna use the same as andyathome used the wild willies. I got some closed foam inserts for it so the tires won't squat too much with the weight of it. So I got some tubing that the motors would fit inside as I don't have a lathe to turn the inside to size. Drilled some holes threaded it for some bolts to hold the motors in there.
Cut some metal to attach the motors to the frame so it will pivot in the middle to have some suspension like movements.
Got the bracket cut out and tacked to the tubes for the motors and bolted to the frame. The front I hard mounted it to the front frame.
For steering I'm gonna go with a 6rpm motor.

I got some different wheels comming with more offset to bring the tires in towards the frame more hopefully they will work. Not sure what I'm gonna use for lifting the box either some actuators or a screw lift. I'm up at work now and hope to get some done when I get home. It'll be a slower process but I have lots of time. The body i will try my hand at styrene.
