I have a simple solution if you can think outside of the box. When my gear stripped, I chucked away the electrics, and now drive the shredder via a crank handle on the side. It gives good excercise, and isn't difficult to turn with anything up to 6 or so sheets.
If you want to do this, open the machine, and remove the smaller gear at the opposite end of the drive (take off the circlip) to expose a hex shaped shaft. You can also chuck all of the electrics, and all but the two gears that are on the shredder shafts. Then cut a hole through both the top casing, and through the bucket, to line up with the shaft end and allow a 9/16 socket to pass through. When reassembled, there is sufficient room to drive the mechanism with a standard 3/8 drive ratchet, although you could make a fancier drive with a handle on.
Happy Days
