Replacement Shaft  Plate and Nuts.
Replacing shaft
Shaft may be supplied loose or carded.
Spare nuts are included.
Unscrew the black plastic nut, note it has a left hand thread so unscrews clockwise.
Remove the old shaft and fit replacement.



If a shaft fails check the condition of the plate, it may be a good time to replace the complete unit.


Reasons for Shaft failure
Almost all shaft failures are caused by not following the instructions.
If the tool is used correctly shaft failures are rare, and usually occur after years of heavy use.
When the tool is not presented at right angles to the surface the shaft bends backwards and forwards on each rotation of the tool, up to 3000 times per minute. It can take this for a limited time but with prolonged misuse the high tensile steel wires in the shaft break due to metal fatigue.

Dust also dries out the oil on the center of the shaft and during storage dampness or condensation may start rusting in the wire core. As well as weakening the metal the rust particles act as an abrasive causing further damage when next used. To prevent this oil the center of the shaft occasionally.


Old version
The original Flexidisc had a different shaft design with two identical steel nuts (more details).
These are a minimum of 20 years old, replacements are not available.
As a special bonus if you return at least one of the two old style nuts with your order for a new unit we will give you a free mini plate, normally 4.50, as we occasionally get asked for spare old style nuts.

Replacing plate
Unscrew the black plastic nut, note it has a left hand thread so unscrews clockwise.
Remove the shaft and fit it into new plate.
Ensure the pip on the plate locates into the hole in the shaft.
Tighten the nut securely.

Damage to the plate Velcro type hook surface.
Damage to the plate is rare if the tool is used correctly
The usual cause for discs not attaching firmly to the plate is because of previously using the sander without attaching a disc which permanently damages the hooks on the plate.
A less obvious cause is the false economy of using cheaper quality discs which can generate heat. The heat passes through the disc and if it gets hot enough it can melt the tips of the hooks. A similar heating effect can occur if excessive pressure is applied during use.
Catching the edge of the sander against protruding objects like nails can slice the rubber under the surface.

The original Flexidisc had a different shaft design with two identical steel nuts and no recess for the plate pip (more details). These are a minimum of 20 years old so replacements are not available.
