Wheels binding up - please help

[Railman66]

Hi - I am trying to use BBB wheels and technic beams for rods (the thin kind) and no matter what I do, the wheels bind up. I am working on a simple 0-6-0 configuration with the center wheels non-flanged. Do any of you have any suggestions on pins or a design that won't bind? I am at a loss. Thanks!

I had similar problems with my Type 08 Diesel that I used Medium wheels on in an 0-6-0 configuration with the centre pair un-flanged. Whatever I did they seemed to run for a few minutes then grind to a halt. I was using a PF Medium motor with technic gears. I tied loads of different ways, changing the gear ratio, changing the wheels around so different ones were un-flanged, loosening the rods, tightening the rods, but nothing worked. In the end I changed the rods to single bit Technic lift arms.Then it worked perfectly OK. Sometimes it is the obvious solution, I think using the beams I just had too many joints that i could not get the right tension or all of them being the same, whatever, but it worked.

I assume of course that you have got them off set? Otherwise that will tend to cease them up. But I think the point being is that it was the rod set-up rather than the wheels.

Do you have any images of the problem?

Not sure what you mean by binding up. Do you mean the pins in the wheels snag on the chassis or do you mean that the beams connecting the wheels go off-horizontal and lock up?

If it's the latter then you probably haven't "quartered" the wheels. Basically, if on one side of the engine the pins are at 12 o'clock then on the other they should be at 3 o'clock, not 6 o'clock like the pedals on a bicycle.

I hope that makes sense?

Was not quatering! Was trying same and opposite but not quarter - thanks!
