Fixing 8" disk hubs

[Richard A. Cini]

All:

 

            I'm restoring an IMSAI system which has an Icom "Frugal Floppy"
system setup (8" FD-400 drives). I've been getting CRC errors since I got it
running a few weeks ago, so I decided to run it with the cover off to try to
see what's going on. Tonight I noticed that the floppy disk itself wasn't
spinning. The hub engages when the door closes but it must be *just* missing
contacting the diskette by *this* much.

 

            What kind of tricks are people using to improve the contact
between the floppy disk and the spindle hub? I remember they made "hub
protectors" for 5.25" disks - is there something similar? Other ideas?

 

            As always, thanks.
