Fitting 7750 hands on a 28XX - 2mm OD - 1.5mm ID / 1.2mm OD - 0.9mm ID tubes available?


Recommended Posts

I need to fit ETA 7750 hands (hour and minute, 2mm/1.2mm did) onto an ETA 2892 (hour and minute, 1.5mm/0.9mm).  Is there any supplier of tubes to fit inside the hand tubes to allow this installation.  These tubes would need to be 2mm outer diameter - 1,.5mm inner diameter for the hour hand and 1.2mm outer diameter - 0.9mm inner diameter for the minute hand?  I suppose I can make these tubes myself, but if there is a supplier that sells these ready made it would save me some trouble and time.  Also, is there a supplier of tubes that would heighten the tube of EZA 2892 hands on the pinion?
