On anything but the thinnest twigs, the old hedge clipper will bind and I'll
hear that loud squealing noise. I took it apart and inside there is a rotating
wheel with sort of splines on it, which is driven by the motor. This presses
into a sort of cylinder and the friction fit drives the cylinder, which works
the clipper teeth. It's old and worn, so it slips and squeals.
Is there any way to repair it to get another season or two out of it? Thanks.
You could try some epoxy - some types are pretty strong, and also stand
up well to vibration, heat, dirt, grease etc.
I wonder if the wheel is designed to be a weak point though, saving the
motor if the blades jam (a bit like mower blade keys that are supposed to
shear rather than causing more severe engine damage if the blade hits
something solid). If that's the case, replacement wheels might be
available at a reasonable cost.
