Hi all
Any suggestions where to find two 50Hz-Pulleys for the 8" Floppy drive
Mitsubishi M2894-63B?
If there also the appropriate ribbon gummies available, I would be very
happy.

Thomas
Thomas's floppydrive is currently on my bench : as we were unable to find the rights
parts I proceeded to 3D print them.
A sleeve for the existing 60 Hz pulley was made from PLA, a replacement belt was printed
using "Ninjaflex".
The resulting combination is already running for several hours, the belt is as flexible as
the original and shows no signs of wear yet.
( This particular drive has the distinction of using a true rubber belt, not the
reinforced textile band you normally see )
This ninjaflex material could potentially be very useful in producing capstans....
Experiments will follow as soon as time permits !
