How do you get the front suspension to move up and down with the steering shaft. I fell short and ordered the parts, I built the model and it did not really move. Do you know why the travel was well lacked on the driver(left) side? Also, if you have a K'nex man can you put him(or her(your choice)) in?

295887 (author)2958872017-05-19

*other than the steering*

GWorks (author)2958872017-05-21

Actually I built the steering centre a few days ago again, and just like you, I found out that its either steering or the suspension. So it's not your fault.

Explanation: Do you see the ball joint + Y-clip that's attached to the orange piece on the steering shaft? Well, that limits the up and down movement. The right wheel has less problems with this issue.

About the K'nex robot (let's keep 'm genderless ;) I'm not sure if it will fit in, never tried it. But I think it should be able to :) Hope you're still satisfied with the build!

I Built This About 2 Weeks Ago Its Pretty Cool But There Was Some Pieces I Dont Have Or Have Enough Of So I Had To It A Little Differently But It Still Worked

GWorks (author)KnexOnly2017-04-17

Wow! Looks cool! I love the rims + wheels. All black, very nice combo!
That's the best, find solutions even if you don't have everything.
Any problems you encountered when building? I'd like to know so I can further improve :) Thanks a lot for building the model! Have fun

KnexOnly (author)GWorks2017-04-17

no not really it worked pretty well

sonic broom made it! (author)2016-06-27

I just built this the other day it's really nice! But the front suspension breaks really easy.

295887 (author)sonic broom2017-05-06

Maybe you just are to hard on it?

GWorks (author)sonic broom2016-06-27

Woo! Cool you made it! It looks good in standard colours too, I guess. Did you have problems with the part count just like Dannicb in the comment below? Then I'd like to know ofc.
What did you use as "shock absorber"? An elastic band?

What exactly did break? Something like the ball-joint connection? They're not too sturdy, but I didn't have problems with them myself. Thanks for telling me, though!

sonic broom (author)GWorks2016-06-29

I used a rubber band. I did not have any problems with the part count I just decided not to build the roof.

Dannicb made it! (author)2016-05-27

I made this truck but you need to re do your parts list I keep my knex at work and counted out only the knex parts I needed per the list so that I could make this at home I couldn't make the roof because you undercounted green/black rods and white/silver rods also blue spacers and clips with rod ends also you can't attach a large clip in the manner suggested in the instructions the pile of parts in the picture is what was listed for the roof that I couldn't make because I didn't have any rods left

295887 (author)Dannicb2017-05-06

I never had problems with it. Maybe you miscounted the parts?

GWorks (author)Dannicb2016-05-28

Hi Dannicb,
I was very pleased to hear and see (although the picture is upside-down) that you made my model! But unfortunately, with some difficulties :/

Could you provide the quantities of parts that you are missing? That would be the easiest way to update the parts list. I am only human, so I do make mistakes. Sorry for that.

Also, if you need help with that clip, please be more clear in what you mean. Which step? which picture? I made everything myself, and all connections are legitimate.

Please use interpuntion next time, that makes reading a lot easier.

martijnb95 (author)2015-04-17

i like the details! very pleasing for the eye. also nice to see that the model is functional (doors, steering).

GWorks (author)martijnb952015-04-17

Thanks alot for your kind comment!
I want to make a video as soon as possible, so I can put it in the ible :)
It's up for voting (they have to check it still) for the knex competition, so a vote would be awesome! ^^

martijnb95 (author)GWorks2015-04-19

i would vote, if i were not in the same contest. good luck to you!

GWorks (author)martijnb952015-04-19

How about a vote for a vote? ;) I prefer our creations above guns at all times :P
And indeed, good luck :D

martijnb95 (author)GWorks2015-04-21

I usually do not vote for vote, but hey, why not? :)

sandroknexmaster (author)2015-04-18

Looks good!

GWorks (author)sandroknexmaster2015-04-19

Thank you ^^

didexo (author)2015-04-18

Very cool!

GWorks (author)didexo2015-04-19

Thanks :)
Feel free to give me a vote in the knex contest ;)

Harvey knex (author)2015-04-19

Very cool you need to find a way to put a motor in it

GWorks (author)Harvey knex 2015-04-19

Kinda true. But without motor makes this a model availble to almost anyone because the piece count is not that high. Also, a suspension system this small (smallest as far as I know) is very hard to power. I've thought to replicate the LEGO drivetrain system for knex in 3D, but so far no plans to actually do this.

Thanks for your comment and vote if you want ;)

sonic broom (author)2015-04-16

This is very cool but do you need to use the little orange parts?

GWorks (author)sonic broom2015-04-18

Err, yes? why are you asking? If you wouldn't need to use them, I would have left them out...

sonic broom (author)GWorks2015-04-18

Because i do not have those parts and i was just wondering if they where need for the function of the 4x4. Good luck in the contest.

GWorks (author)sonic broom2015-04-18

I see, well for the suspension and the steering, they are not used (if you mean that by "the funcion of the 4x4") They just make the rear stronger.
Same to you.
