Okay. I have to ask this question. After looking at your photos, how is that semi pose to turn when you have a set of wheels center of the frame and then back about 30 scale scale feet dual set of wheels? I know it's only a model.. but I am curious as if was a real life vehicle, how would it turn.

Well the center would have to articulate with the front wheels.

Jim, I am building an extended Mack with a DROM tank and it needed a lift axle. When I got to looking at the internet to see what is out there these days, I found some very cool and very interesting self-steer lifts. They use a tensioner similar to a shock absorber that is connected to the steer rods. Is only tight enough to pull it back to straight/keep out the wobble.

Oh. okay. I'm not too good with these kind of things yet. I have only built like 2 model semis so far in the past. Thanks for shedding light on this stuff and helping me understand this kind of stuff.

I think this project is pretty cool....and turning would be no big deal with all wheel steering.....Either way I am going to watch to see what all goes on this this build!

I'm making the slide out with 1/4 x 3/16 rectangle tube going inside 5/16 x 1/4 tube.

It is truly amazing the ideas that can come from ones creative mind..........

On the steering, since the center axle you have already mounted is a driven (powered) rigid axle with a power divider & dual tires, how exactly will it "articulate" with the front axle??? What happens to the power in the drive shaft when the 1st axle in the rear tandem also has a power divider?

Seems to be a slight stretch of a modern engineering marvel........

The center drive axle is not a locker or a limited slip, at would be able to track as a single wheel wonder.

Thanks Richard

quite the engineering marvel, any pics of one in real life?

Richard I will look for so, but I have seen so wild thing on the show trucking on TV.

Ive driven over the road for some year(in the office now), I must say this quite an awesome build. I do believe there is an articulating drive axle available. Check out Sourkroiys web page for his truck parts, he has numerous resin axles of all types. Being that yours I'd already set I'm with you on the fact it's a model......so let's all use our imaginations a bit and some "make belive" in our minds and just say the darn thing would turn in real life and enjoy build progress. :-)

Thanks Chris , if you are not doing a build of some ones car or truck imagination is a big part of modeling.

OK now back to the build!
