Re: 6X6 Quarry Dump Truck
Thanks IZZY!
Hi Alex, glad to see you on here, boy have I got some news for you! Watch for a PM or I might even give you a call in the next week and thanks, the truck should start moving along, just a few more parts to make for the rear suspension. |

Re: 6X6 Quarry Dump Truck
Cool looking build. Im loving the walking beam set up. that will be a beast with all that articulation. I have been tinkering with a set up like that for my next truck.
I did notice the plastic driveshafts. Just a word of caution. My mack 6 wheeler twisted one of them up on the 1st day I installed it. I had to put metal ones in if I wanted to haul loads with it. same with my cab over freight truck. if i pulled my flat bed it would twist it as well. I keep them for mock ups and then purchase metal shafts for use and abuse. keep the pics coming |

Re: 6X6 Quarry Dump Truck
Rear suspension update, It's done !! Ok so it needs adjusted, tested, painted etc. but at least the fabrcation is done and it appears to work as planned.
Rear suspension centerline crossmember Final assembly shots Drive shafts next. Then I'll power it up and make sure it runs the way I want it too and then work on the bed mechanism. Thanks for looking! |

Re: 6X6 Quarry Dump Truck
Q - who's drive shafts you have up front?

Re: 6X6 Quarry Dump Truck
It's out of an axial crawler and pretty much stretched to its limit, I couldn't get it to come apart flexing the suspension but it only has about 1/2 to 3/4 inch penetration. I used it primarily to set the transfer case location.

Re: 6X6 Quarry Dump Truck
Got the driveshafts done, I need to shorten the inter-axle shaft up a hair. Should be able to power it up this weekend.
Thanks for looking! |

Re: 6X6 Quarry Dump Truck
wow loving the walking beam set up. and the brass tube for the driveshafts!
I had tried the RC4WD plastic driveshafts that look just like the Steel versions. They would twist the star "tube" to the point that the U joints would then slip out. Granted this was with a truck pulling a full load of sand and going over some real harsh ground. On the other hand even my on road Cab over mack twisted a shaft pulling my flat bed when I was backing down a steep hill and then tried to move forward. IMO the RC4WD shafts are only good for trucks that dont get dirty or pull any sort of weight around.

I was thinking about making a walking beam that rubber mounts the axles to the beams and thus keeps the inter axel drive-shaft angle straight at all times. only the front shaft would move in and out of the tube to take up the length difference when traveling over bumps. I know your example is more 1:1 but I always have issues with lots of articulation and the little driveshaft. I went back to the tamiya cups and dog bones between both drive axels because they were performing better than the scale driveshafts did.

Here's some Friday and Saturday updates. Here's a new t-case mount, I didnt like the way the first one turned out. Made a larger cab floor/radio tray. Made the dump box frame/hinge assembly. Thanks for looking! |

Re: 6X6 Quarry Dump Truck
It's coming along nicely. Even though that articulation is too much for that drive shafts I doubt you will ever see that much need for it.
Watch you triangulation when doing your lift mechanism. |

Re: 6X6 Quarry Dump Truck
Looks good so far . Great job on the walking beam , I would only suggest getting metal rod ends , I've broken the plastic 1's I 1st used on my IH9370 with the walking beam (hendrixson )

Re: 6X6 Quarry Dump Truck
Awesome job so far. I'm not up on all the various available parts so I apologize in advance for asking, but what transfer case are you using and where did you get it?

The dump mechanism will be interesting, it will be a slow process until I get comfortable with the set up. Quote:
Hi Finster, thanks for the comment. The t-case is a transmission out of an Axial AX10 Scorpion crawler I parted out. I believe the part number is AX80009. The input shaft has to be modified to use it like this. If you shop eBay or some of the more popular RC Crawler sites, there are better alternatives out there, I just happened to have this collecting dust on a shelf and knew Travis used one in one of his builds so I gave it a shot. |

Re: 6X6 Quarry Dump Truck
Thanks for the info! Oh and I forgot to mention I really like your walking beam setup. I may have to borrow your method(s) for a future build
