Hm, Tony....
If you want *one* piece or two pieces... Then you might pay for the labour. But
then a hub costs several hundreds. At least here in Germany everything involving
manual labour is horribly expensive.
Doing it via CNC makes the thing cheaper if many are made...
Kind regards
Philipp

I also need a few 24 sector packs, for an HP7900
drive. Those should be
easier to make than 16 sector ones, in that it's 'just' an extra notch
midway between the existing ones.
Hm, I will follow the electronic path for RK05
drives now.
But you could modify any drive where you have schematics for.
You don't need a complete hub IIRC> The
sectorign ring is a separate part
fixed on by 4 rivets. It should be possible to jsut replace that.
Really? I
remember the whole thing consisting of two parts. But I might be wrong.
Be warned if you do take the bpack apart that the
platter is not
automatically centroed on the hub. You ahve to put the platter in place,
fir the clamp ring, then put the hub on a suitable spidnle and use a dial
guage to centre it up. A right pain to do...
I did it. I did not have any tools for
centering. I did it as good as possible.
The first result was too "excentric", I did it again. The drive will happily
work with a badly centered disk. But it makes too much vibrations...
A centering cone or anything alike would be great...
cost would be
the programming and setup of the CNC that turns the hubs. Then
Can't anyone turn by hand any more?
