6-wheelers derailing

[jhb171achill]

This little yoke has a huge aversion to staying on the rails, and refuses to do so at all if being shunted.

Thoughts?

Brassmasters 6w suspension Unit http://www.brassmasters.co.uk/cleminson_underframe.htm if you can persuade some on to assemble it.

Try removing the center axle and see if it stays on the track. If so try an source a flangeless wheel set.

 

[jhb171achill]

Good thinking; and that palethorpes thing might be a basis for a 6w scratchbuild….

[Dave]

Take the flanges off the centre wheels.

[Mike 84C]

The palethorpes wagons are not very free running if mine is anything to go by. Is one axle higher than the others? a little bit of play in the center axle may be all it needs?

[Galteemore]

Might be worth checking the back to back as a first step. Gold standard fix is some kind of flexi chassis as identified above, but flangeless wheels are an easy fix. 6 w coaches can be curious beasts and and require a bit of fettling to get round the track…

[David Holman]

We ask our stock to go round ridiculously tight curves. Bogie and four wheelers are usually fine, but six wheels, and indeed longer wheel bases cause problems.

 Some sort of flexible chassis is therefore essential. In 7mm scale, the Alphagraphix 'Cleminson' type works a treat. Flangeless centre wheels may go some way to solving the problem, but one of the outer axles may need to rock and/or pivot to go round tighter curves.

Couple of suggestions,first back to back needs to be checked, then put on a proper flat surface, plate glass or something and make sure all the wheels are sitting on the deck,then check that the central axle can float up and down in relation to the outer pair and that no brake gear etc foul the central wheel.When i've built my own 6 wheel chassis i had it with one end with a fixed axle the other on a rocking axle with the central axle free to move up and down in a set of slotted axle guards with a certain amount of lateral movement.hope this helps Andy.

I'm thinking that, actually. The thing may not be 101% perfectly level. Also, there are several small undulations in the track.

Drag it to Hogans Halt on Sunday JB 
We can have a look at it

[Sean]

I have one of these that i built myself using a 6w hornby van, the middle axle should slide in and out as the wagon goes around corners..

 

if thats a silverfox unit it should be the same chassis from my oggling of the photos, the couplers should also turn through corners

[jhb171achill]

I'll hopefully get an expert eye over it tomorrow - meantime I am expecting four more six-wheeled vehicles, but given the provenance of the maker of them, I know I won't have any worries.

Anyone have any experience of running the new Hornby six-wheelers?
