Cup and cone wheel bearings

I am doing up an old Carlton mixte frame ladies racer to turn into a commuter.

I have transferred over my 27' wheels and decided to true up the rear, which had a bit of wobble and a kink in radial trueness. I did all that and centred the wheel perfectly, then decided to repack the bearings.

One of the cones on the cassette side was pitted. I have replaced it with another, but it is longer and this has thrown the centre-ing of the wheel out.

I have been trying to find a cone of exactly the same size (no luck so far).

I was also thinking smaller smaller spacers would sort this. Any ideas on this? Do people just cut them for correct length or something?

I assume there is no reason why I can't use different length cones?

Another alternative would be to loosen the spokes and then re-dish the wheel for the new set-up. But that seems extreme - an unwise for a wheel that works fine at the moment.

    What are the dimensions of the old cone? I could have a rummage.

    I have measured it at 12 mm long.

    I'll have a rummage...Is it a QR or a solid axle?

    Really kind of you, thanks, It's a QR.

    Any reason why you can't mix cone lengths?

    No reason not to mix them but you must keep to the original OLD. The drive side cone also decides where the top sprocket is in relation to the drop-out. Not a problem if it has enough chain clearence and you only use one wheel.
    No need to re-dish if it all clears OK. I have dished wheels biased towards the non drive side a little for better strength before and never noticed any difference riding.

    I have a cone that measures 12.35mm. Problem is that it is from a Raleigh solid axle which is a different thread than my Campy and Shimano QR wheels. If you think it is of any use, I'll pop it in the post for you. If not, I might be able to find a spacer to compensate for your larger cone.

    That's very generous offer. Thanks. I have sorted this and was being a bit dumb. I am not that practised at this and then forget what I did the last time ... familiar cycling tinkering story.

    I had been doing this with the left cone locked tight. Once I loosed that I could just shift the cones to the right to align wheel in the frame. I only have two and a bit threads of axle on the right side, but it is enough to stay in place.

    I am lucky too in that this wheel has a five speed freewheel which I put on with plenty of copper slip, so it comes off easily. Means I can see what I am doing and put the wheel on without the freewheel for fine tuning in situ.
