The 65mm barrel on my 450 YCL has a fine crack running from ring to ring. I have seen moisture emerging through this crack but infrequently. Can this be easily repaired (by me)? If so, how? If not, then I would like to replace it. So, if anyone has a compatible barrel, not cracked, in your drawer that you would be willing to sell for less than $30 (I'm saving for a 650) I'd be a happy player.

You could 'fix' it yourself with either beeswax (temporary-to-permanent) or Cyanoacrylate glue (AKA Krazy Glue), which is a probably permanent, but ugly solution. However, the best solution would probably be to take it to a good repair person who will either pin it or band it. That way, it'll look good and the crack won't open up again. Ever.
If the barrel is a good one and sounds good, go ahead and get it fixed. If it is not, and you'd really like an excuse to get another one, try fixing it yourself and see if it works. Then it's no problem if the solution doesn't work, or you save some money.

I wouldn't recommend the self repair.
The type of crazy glue required is not the consumer stuff you get at the quick mart. It is a version that is less viscous and takes longer to dry. A friend of mine tried to repair a cracked wooden head joint. That was a mess!
Pinning (or carbon banding) a barrel may only be about $30 (maybe). Ask a reputable repairman BEFORE you try learning on something you still want to use.

>> either beeswax (temporary-to-permanent) <<
Putting any wax could make it much harder to later repair it properly, since you might never be able to remove all of it thoroughly, making it much worse to glue.
>> or Cyanoacrylate glue (AKA Krazy Glue), which is a probably permanent, but ugly solution. <<
It's not ugly. The wya it looks has more to do with whoever does it than the method. Using super glue (cyanoacrylate) can be about as invisible as any other method.
>> the best solution would probably be to take it to a good repair person who will either pin it or band it. That way, it'll look good and the crack won't open up again. Ever <<
Often unnecessary. I prefer to glue only, and only if it re-opens consider other options. Cracks usually don't re-open when glued well, though sometimes they do. I've pinned and banded cracks, and never had any that I've seen re-open, but I have seen pinned and banded crack open, and that's not because a poor repair. It's not common but it's not 100% either.
>> The type of crazy glue required is not the consumer stuff you get at the quick mart. <<
Not necessarily. I've tried many types, including the "famous" ones (like Loctite, and some brands sold from musical instrument repair suppliers). The type usually available at a small random store in my neighborhood happens to be just as good as anything I've tried. Most regular super glue is very thin (low viscosity) unless it is the gel type.
Old super glue can become thicker though.

What clarnibass says! I've used regular super glue on several bells/barrels of old clarinets and it's worked just fine. Just carefully fill the crack from the outside and after it dries sand the excess carefully with very fine sandpaper.
Best regards,

Use the thinnest, low viscosity, superglue (that's also the fastest curing), so that it really penetrates into the crack. In some cases to improve penetration I first drilled .5 mm holes along the cracks, in this bell (photo) from the inside only and not visible from the outside. This repair was done 5 years ago, and it hasn't reopened since then.
Over here you get assorted superglue from technical or modeller mail order shops like Conrad or Höllein.

The thinnest glue is available from a hobby shop. Be careful. It runs much faster than water and can make a mess. Use ventilation.

Thanks to all for your comments. I have some ZAP THIN CA that I use for jewelry repair. I'll give that a try and see how it goes.

I use Zap CA for crack repair (and with wood dust as filler) as that wicks right into cracks and sets almost instantly making it workable within next to no time.
