Interchangeability of nutted axles and QR forks and vice versa

[horizon]

Just running through/summarising the options again:

1. Use a 9mm QR willy-nilly in the 10mm drop-out and tighten well.

2. File a 10mm axle down on two sides to 9mm (.5mm per side) but insert the axle always on the correct side (flats for 9mm, threads for 10mm) depending on the drop-out.

3. Bulk out a 9mm axle with tape in the 10mm drop-out, remove tape for use in a 9mm drop-out.

4. Use a short section of 1mm thick alu tubing as an adaptor for the 9mm axle in the 10mm drop-out. I'm presuming that the "tube" has to be no longer than the width of the drop-out in order to allow the QR to grip the fork against the hub. So effectively this would be a thick (2mm?) 10mm "washer" with a 9mm hole (if I'm right). Or several washers of course. Hmmm.

5. Filing down the 9mm drop-outs. I've decided against this as it means filing down all the drop-outs where I might want to use the wheel rather than one or two axles at most. I'm going to go with addressing the issue at the axle.

6. Changing the 10mm forks: these are on the cheap, serviceable Die Hard and seems a waste of time and money. Giving up on the interchangeabilty and just going for one or other is also a possible strategy.

Of the above, I guess I like the 'flats on the 10mm axle' approach the best. btw if you use a spacer, it must be 0.5mm wall thickness, not 1.0mm.
