Only Meade has parts. Usually they want you to send the scope back to them for repairs. However you can contact their customer service department and ask if they will sell you just the part:

Is there a gear kit for the Fellowes MS-450CS Micro Shredder?


Hello Jay

I have the same problem. I found a place that sells nylon gears. They are not to good in responding back though.

This is the email address and the lady's name is Delores
sdp-sisupport@sdp-si.com

The cog below is shattered on the spindle and the bottom one, the skew spindle has chewed a hole in the cog in one place. I would like them all replaced with bronze.

The contrast and brightness can be reset --- here is the manual -- how to do this is listed in the manual. If this does not repair the controller then you will need to buy a new hand controller-- the 497 hand controller is available used on Ebay from time to time.

Cannot get rear derailer to work properly 24 inch girls evolution


Don't start messing with the derailleur yet! Make sure your shifting trouble isn't due to something else, such as a warped, dirty, or stretched chain, gummed-up pulleys, crud in the cable housing, trapped cable, or a bent derailleur hanger
Clean the chain and the rear derailleur pulleys. Pull the chain away from each pulley, and turn the pulley to make sure it can move freely. A pulley that offers resistance to turning must be replaced.
Now check the cable to be sure it slides freely. Mud and grit within the cable housing, or on a cable-guide, can keep the derailleur from moving a "full gear" during downshifts. If the cable doesn't slide freely in the housing, you may be able to clean or lube it to restore smooth shifting.
Let the high-gear limit screw. In your highest gear on the shifter, and with the chain on the smallest cog, position the derailleur so the upper pulley exactly matches the teeth of the small cog. Run the chain a bit with the front derailleur in the large ring, adjusting the limit screw until the pulley and the cog seem to match perfectly.

Setting the high-gear (small cog) limiting screw.



Once you're sure the derailleur matches the cog, move it just a whisker (1/8 to 1/4 turn) towards the other cogs. (You may need to readjust a bit if you get chain-skip.)

Closeup of setting the limiting screw.



Now adjust the low-gear limit screw. Shift into the lowest gear (largest cog). If it won't go, loosen the limit screw. With the chain on the largest cog (and the front derailleur in the small chainring), adjust the derailleur so the upper pulley exactly matches the teeth of the large cog.Once it's perfect, turn the limit screw so it moves the derailleur a tiny amount towards the other cogs (1/8 to 1/4 turn usually works).

Setting the low-gear (largest cog) limiting screw.



Now shift to the highest gear (smallest cog). Push the shift lever to downshift one gear (go from the smallest cog to the next-smallest). If it doesn't shift, tighten the cable with the barrel adjuster, 1/2 turn counter-clockwise. Backshift and try again. Continue tightening until it shifts. If it overshifts, going from the smallest cog to the third-smallest, loosen the cable by turning 1/2 turn clockwise. Backshift and repeat until it shifts exactly from the small to the next-smallest cog.

Fine adjustment of tension in the derailleur cable.





Now go to the second-smallest ring. Tighten or loosen the cable slightly, until the outer side plates of the chain are just clearing the third-smallest cog. Shift up and down, fine-tuning until you're satisfied.

Checking the position of the chain on the cogs.

Found this on another site (fixed4free.com) posted by Dave in Jan 2009:

This is one of those things where a picture would be worth a thousand words, but as I can't put pictures on this site, the words will have to do!
- Turn the orange cog anti-clockwise as far as it will go, (putting the nozzle to direct the water to the conditioner drawer)
- Look closely at the orange cog and you'll see that the last-but-one tooth at each end of the row is shorter than the rest. Looking from above and standing at the front of the machine, I call the rightmost tooth on this cog number 1, the short tooth number 2 etc. (my cog has 17 teeth)
- Position the white cog so that (looking from above) the leftmost tooth on the top (incomplete) row of this cog is between teeth 2 and 3 of the orange cog. This should be such that if the white cog rotates anti-clockwise it will turn the orange cog.
Now the difficult bit:
- The shaft that the yellow cog fits on has four vertical 'webs' running down it. Look closely and you'll see that one of these is bigger than the other three. As you would expect, if you look carefully at the centre of the yellow cog it has three small slots and one bigger one spaced around the hole.
- This shaft can be VERY CAREFULLY rotated if you pull it gently upwards against it's spring and wiggle it while twisting it. NEVER force it, the cogs underneath are VERY fragile. If it won't turn, just let go, and try again.
- Look again at the white cog, and you'll see that two of the teeth on the lower (complete) set of teeth have no slot between them, they make a tooth that is 'double width'.
- Look at the yellow cog and you'll see that it has a 'double width' slot on it's lower row.
- The challenge is to rotate the yellow cog's shaft so that you can fit the yellow cog on it, aligning the double-width slot on the yellow cog with the big tooth on the white cog. This is just a case of trial and error, but is the key to getting everything back together.

COMPLICATED BIT OF EXPLANATION!!
The yellow cog only ever turns clockwise and the white cog is a clever bit of engineering allowing AEG to move the nozzle (orange cog) backwards and forwards across the five positions.
The yellow cog turns the orange cog anti-clockwise until it runs out of teeth, then the white cog turns the orange cog the other way.
After a full rotation of the yellow cog, the orange one has moved clockwise to the stain-treatment position and the by-pass beyond, then anti-clockwise back to the conditioner position.
