Brass gears: what are your thoughts?

[Bob Tidbury]

As Kev said Never had a brass gear split but admit they are noisier ,a dab of graphite quietens them down for a while but  does wear off .
I think the white nylon gears were also very good I have never had any problems with them ,I have no idea what type of nulln Farish used but was told that those gears were very expensive compared to the black plastic .
I havnt had a problem with the thick black plastic ones yet but I have heard some people have ,time will tell .

Just my personal opinion on this - I have never had a brass gear split!

I've never had a Kato or Dapol gear split...


The 2mm Scale Association offer worm gears in Acetal or brass. Their spur gears are all brass. They also offer skew cut gears for meshing with the worm gears which will help reduce wear. As would helical cut worm/spur gear but perhaps that's going a bit too far?

@Will_J I've not seen what your motor bogie will go in. Care to share?

As already mentioned the 2mm Association sell brass gears, in fact they actually make them!

The problem that's been with the Acetal/plastic gears is that the axle hole is too small, so when these gears are fitted they are immediately under stress!
