Steam Locomotive drive wheels

[Anonymous]

Has anyone a good suggestion how to fix a drive wheel to the axle so that it will not slip around and cause the con rods to lock-up? The problem as I see it is that as nearly all driver wheels are plastic spoked/centred they are press fitted onto the metal axle. If for some reason they start to slip--usually without warning-- it seems near impossible to fix them to prevent this. I have a Bachman + Northern 4-8-4 and one driver keeps slipping & locking up the rods. Have tried super glue. Not much else comes to mind. If only the centres were metal you might be able to solder the problem. How about it all you experts?[?][:(]

The best solution is the Bowser chassis:

The only adhesive that might work is Cyanopoxy:

CA does not have a chance in this sort of application, which is shear. CA is very strong in tension, and not at all strong in shear.

You have the 'old Bachmann steam., not the current.
The axles would turn inside the press-fitted wheels and the valve gear would lock up.
They need to be scrapped, and replaced.

Bachmann will replace with new units (and better drive) for $15 each (and you pay the postage both ways). Good Deal! If one of your engines is the Santa Fe 4-8-4 (or 2-10-4) - there is no replacement as the dies were broken or lost.
