Mike,
Fair enough, I'll wait a bit. We will all need your buffers!
Have just enjoyed a quick session on the lathe following unklian's explanation.
1. The slaters wheels were removed from axle, chucked rear face outward, simply held on the tread, and 0.5mm removed across the rear face. Overall tyre thickness reduced to 6.5mm. The spokes were rebated by a further 1.0mm. for appearances sake.
2. Then mounted in turn on a mandrel front face out, the flanges were reduced to 1.6mm depth and filed to profile.
3. Axle was mounted, one end in the 3 jaw, outer end in a piece of pb held in tailstock (drilled from chuck). Taper turned with topslide at iro 0.75 degrees. Taper turned from tailstock to centre of axle first, then reversed and the other side cut to meet. The original 6.35mm dia. was held at each end.
4. Two washers turned up at c. 1.0mm thickness. OD approx 10mm to represent part of the wheel hub as shown on a drawing of the period. All pushed back on and Back to Back checked at 60.00mm +/- o.1 mm
All good fun, and quick. The spoke rear edges feathered a little but a quick scrape with knife shaved it off (although I can see a couple of missed bits).
