Blimey even I knew what the cusp is.... :vista: Flip me it's getting crowded back here.... :iploffy said:By the way whats a cusp please?,this is all tooo technical
Can I go to the back of the class now

I have had sets of wheels where I get a lovely running fit on one end of the axle, yet the other end won't even go into a bearing!Simon said:one thing that REALLY hacks me off is the way that the bearings and journals of the wagon wheels that they supply (in G1 at least) don't reliably work together. A function of variations in tolerances of machining I think and it really irritates me. It isn't a problem every time but on this wagon for example, one wheelset is fine and the other isn't. (with the same bearings being tried in succession on the axle ends)
You have a lathe, do you not?Hence I am farting about with wet and dry paper and will eventually get it to all work but at the expense of a really good engineered fit.
Yes.I think the journal sizes in G1 are bloody silly. The 2mm axle ends on Daver Hammersleys wheels are much more appropriate and I am pretty certain that elementary geometry would show you get less friction and rolling resistance on a smaller diameter.
Yet in 4mm Exactoscale can produce some very nice accurate wheelsets http://www.exactoscale.co.uk/4mmrollingstockinst.htmliploffy said:It always amazes me the rubbish was as modellers are expected to take you buy something and you expect it to work first time every time what an endorsement no 2 axles are the same not good enough really is it
no 2 axles are the same

3/16" collet in the collet chuck, use an axle end which fits to set your tool, and then skim any axles which are not right.

They are not 2mm the thing with ballraces is that they need to be a push fit onto the axle to work properly.Simon said:Is that across the "Roxey" wheels and if so do all the bearings supplied nonetheless fit?
Having asked that I guess you didn't get the bearings as you are intending to ball race the whole job.

Not a 1/32 4F.
I couldn't take the pressure.
