Twiggy drive servicing

Alas - if only it was so!!!
Yes, only disks.

I did find this site in Italy that has reported they were going to make new twiggy drives - but whereas the site is still up - no one seems to be home to answer the emails or web postings.

I started a thread in the files section ... Twiggy Media

I was helping Mauro (or at least trying to) with some details for this project starting in 2009; periodically there is progress, but it is a major and not inexpensive job.

Does anyone know if the press-fit plastic spindle (?) in the Twiggy drive can be sourced from another 5.25" floppy drive? I'm talking about the black plastic rotating disk in the center:

It comes down onto the topside of the FileWare disk's central hub and facilitates rotation of the donut.

If you mean the thing that clamps the hub of the media and spins (see pic), then I'm not aware of any substitutes -- let us know if you find any ... I'd guess an adequate replacement might be 3d printable, though not a trivial design task.

Recall that the Twiggy & Widget designs were consequences of the so-called NIH (Not Invented Here) discrimination syndrome at Apple at the time, so deviations from industry standard were often severe.

Although the clips around the perimeter are springy, there is almost no friction between this one and the spindle, so I think the spring requirement is minimal and perhaps unnecessary if the fit is good.

I was able to 3d print one of the kickout clips, and it seemed to work ok... it needs some design tweaks to print better and be more durable but as a proof of concept I think it is successful.
