A DIY tool to unscrew the top of the cassette

John McMurdo

This tool takes some of the pressure off the plastic lugs.

In the flap from the top of the cassette, drill two holes, slotted to make a keyhole shape. They are at 70mm centers on our cassette; yours might differ.

The stick is a piece of broom handle, 300mm long.

Cut a slice out of it. This isn’t necessary but makes it fit more closely.

Partially screw in two screws to match the holes you drilled in the cassette flap.

Use this stick as a lever to turn the flap without putting too much pressure on the lugs , which are only plastic and easily broken.
