I'm no expert, but I have picked up on a few little things over the years that I would like to share. Always buy your reels in pairs. That way, if you end up with a bunch of leftover parts when you clean your reel, you can take the other one apart and see where they are supposed to go. Lay everything on a towel. Parts don't bounce when they hit a soft towel. If you're hard of seeing, use a white towel so you can locate all the parts easier. When you take a reel apart, lay the pieces in a line in the order you took it apart. Use screwdrivers that fit the screws properly so you don't mess up the slots.
