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.
