It's still not finished, but I needed to have it partially assembled in order to take some measurements and design the cable ends, so I thought I would take some pictures and see what people think so far. This is a push-pull cable steering system that will be put in motion with a stepper motor. The motor will spin the lead screw and in turn push and pull the cables to each differential. So far I have overcome a bunch of issues, and hopefully it will be operational within a couple of weeks. I think I have about 65 hours into this steering as of yesterday. The first 4 images show the lead screw, positioning nut, cable hardware and tubing, and the last is one of the pivots on the diff.

that looks like its gonna be a pretty bad ***** rock crawler when you get it all done, just out of curiosity, why did you post pix in the giant scale section? with the T-maxx tranny and Clod style axles, wont it be more like 1/8 scale?

anyway its a great idea [sm=thumbs_up.gif]

Anomie

The wheelbase is more than 20", and the overall length of the body is about 29", so it's a tad large for it's tranny. Closer to 1/6 scale, I believe.

Thanks for the compliment!

have you seen the actual size of his truck [X(] this is his custom machined build... no traxxas BS here[:-]

Anomie

Thanks, dude :-)

Dont get me wrong, i'm not knockin your work, its top notch [sm=thumbs_up.gif], but isnt that a Billet T-maxx tranny?

[X(] HOLY SHMOLY,
That is incredible, nice work. Your truck is going to be insane when finished.

Sweet squared!!!! Very nice indeed!!

Wow, those metal tubings, all aluminum construction and cleanliness are...beautiful! Which CAD software have you designed your parts in and I assume you use a CNC to make everything? And what kind of stepper specs are you looking for...and how would you drive the stepper with an rx?

Amazing job btw!

Yes, it is a T-Maxx tranny. I needed something that matched all of the machined parts, and the billet case was just the touch. Unfortunately, most of the functioning has been disabled to operate as a single-speed forward-only tranny.

Anomie

Thanks to everyone for the compliments!

I don't have access to any CAD software or CNC machinery. All of the work I have done is on a manual Bridgeport Series 1 mill and a Hardinge 6" lathe. The only advantage I have is a DRO on each machine.

Just took alook at your gallery, Can't imagine the hours you have into that. Wonderful job![8D]

i dont understand it

Anomie

Come to think of it, neither do I!

The motor will turn the lead screw, and when the screw turns in one direction or the other, it pushes and pulls the cables to swing the steering. There is only one cable in the pictures. I haven't finished building it yet, but wanted to get some pictures up here to solicit opinions.

I really appreciate everyone's comments! Thanks!

can u take a wide shot or something

lt250dave

so are you going to have front and rear steer? and if so will you be using one motor to drive the lead screw to operate front and rear steer at the same time?

Anomie

Yes, it will steer both ends together. The stepper motor will be driving a worm gear.

I'll try to get a better shot when it's assembled further.
