<p>i made it but one wheel is always strongest other one.</p>
<p>Here's my version:<br><a href="https://www.instructables.com/id/Smallest-KNEX-Differential/" rel="nofollow">https://www.instructables.com/id/Smallest-KNEX-Diff...</a> </p>
where would u put the axel???
The whells go on the yellow rods then it is driven from the yellow gear.<br>
I found a way of holding the yellow gear on without the wire but it does require a broken rod.<br><br>
&nbsp;I posted something very similar a while ago (here: <a href="https://www.instructables.com/community/Knex-differential/" rel="nofollow">www.instructables.com/community/Knex-differential/</a>&nbsp;). &nbsp;Instead of using wire I modified (drilled a hole in) the yellow gear. &nbsp;Your cage requires more pieces, but the additional structure may make it sturdier, I'd have to build one to find out.
I've maked and it works really good. i m making a car with it and also the <a rel="nofollow" href="https://www.instructables.com/id/Knex_Car_Steering_mechanism_with_ajustable_steerin/">steer system from king1000</a>.<br/>
