Hello All,
I used flex rods in my design ,mainly for looks.
They don't really flex in my design.
My train is a 4 6 2.
Is this the part #3747, which you are talking about?I used a 3 long technic axel
with stud on one end.This is on the middle drive wheel,that moves sideways.It
has not been deflanged.The push rods connecting to the connecting rod also moves
sideways.On the other drive wheels , I use a technic half pin and round 1*1
plate
It works 99% of the time. The only fault is that the connecting rods come off
some times at fast speeds. I've got a few ideas on how to fix it, but just
havn't done it yet.I was only taking it slow in the corners at BrickFest PDX,
Because I did not want it smashing all over the ground.
Some silicon grease on the moving joints ,should really help.
But don't get it on the wheel rim.
I havn't tried this.
But I have used it in some Lego gear boxes.
It's very hard to explain without detailed pictures.
I hope to get some more pictures up soon.
Showing in close detail , what parts I used.
Including a few Pictures of it pulled apart.
Trying to show some instruction on how I built it.
Thanks, Teunis M>ltc
