Introduction
Coins corrode when they come into contact with chemicals, minerals or the natural elements. Corrosion is unsightly and can cause lasting damage, such as pitting and scarring, to the surface of the coins. Coin collectors and hobbyists can remove corrosion from coins using a number of homegrown methods.
Some say Salvage & Repair of Cracked Cymbals can’t be done. We say: Of course it can be done! The question is: Can it be done with acceptable results? The answer is depending on three factors:
- Type, Location and Severity of Damage
- Method of Repair
- Expectation of Results
The severity will of course have the biggest impact on the end result. Sometimes it’s just simply not worth the effort to repair cracked cymbals. In this article however, we’ll attempt to salvage even the most severe cases, just for the sake of reporting the results.
There are two basic approaches we’ll explore. the first is simply salvaging. This approach simply means removing the entire damaged area or stopping the decay in it’s tracks. The shape of the removed portion plays a huge impact on the end result. The second approach is repairing. We’ll test numerous methods and report back with sound samples and step-by-step instructions. methods include brazing, soldering and other ways of patching.
Regardless of which approach we take it’s important to understand that the cymbal will never sound the way it did before it cracked. Results will vary from sounding like a broken cheap china, to “Wow, that’s cool sounding”.

When a cymbal has a small crack at the edge, the easiest and most common fix is to simply remove the crack and surrounding material. The less material removed, the less impact it will have on the sound. Fortunately, the slightly decreased weight also results in the fixed portion naturally rotating towards the highest point, which is the farthest from where we hit. Although it is advisable to remove as little material as possible, it is vital that the entire crack, including any hairlines at the end, is removed. Otherwise it won’t take long until the crack reappears along it’s original path. However we also need to balance minimum material removal with as smooth a “cut” line as possible. Both for the sake of not converting the cymbal into a deadly weapon and to avoid any sharp interior corners as those would be starting points for new cracks.
Many times this salvage method yields quite acceptable results and the cymbal can be used for it’s original purpose, although with a slightly altered sound. Other times, this method results in an obnoxious “Broingy” sound. This is caused by the disrupted balance in the cymbal. The portion of the perimeter that is now interrupted is no longer controlled by it’s own circumference. Lower frequency vibrations are now free to form at the flaps and spread inwards. “Brrrrrrooooiingngngngng”.
The Paiste Crash to the left exhibits a slight bit of “broingyness” but well within acceptable levels. Removal was done with a Dremel loaded with a high-speed cutting disk. After cutting the edge was ground smooth with an emery cloth “barrel” also loaded in the Dremel.
If the minimum removal method results in above described “broing” we need to remove a wider, but smoother arc spanning up to half the cymbals circumference. Often this is enough to restore the balance to a point that the “broing” is reduced to acceptable levels.
Repairing Cracked Cymbals
Just cracked your favourite cymbal(s)?Hoping there is some magic trick that will let you repair it good as new? Well, I'm sorry to say that once a cymbal starts cracking, it's all down hill from here on out. There is no 100% reliable way to repair a crack, but you do have a few options, however none are particularly desireable or attractive.
Lathing
Should you REALLY want to save your cymbal, you could try having it lathed. This means that someone who knows what they're doing will shave about two inches from around the outer edge of the cymbal in order to prevent the crack from spreading futher. For example, if you've got a 17' crash, you might end up with a 15' crash (or possibly less) after the work has been done. There's no guarantee that this will work however as micro cracks can form in the metal which are unseen (for now) but will possible show in the future. If you're going to go this route, you need to catch the crack EARLY (i.e. stop playing it as soon as you see a crack and seek help).
Drilling
Some people believe that drilling the cymbal at the top of the crack will slow its progress. Whilst this is true, remember that you're creating a big hole in your cymbal and whilst it MAY slow the crack from progressing further, your cymbal will lose a lot of volume and sounds pretty awful from now on. I've recently done this to one of my cymbals (Sabian AA Crash) which has 2 small cracks which very quickly developed into 2 large cracks :(
Cutting Out
Again, you can simply cut a wedge out of the cymbal which contains a crack but this is similar to drilling and produces a similar sound.
You're basically left with one option; Buy a new cymbal. Yes, I know that's not what you wanted to hear, but that's life I'm afraid.
Cracked cymbals are sometimes a manufacturing defect, but this happens VERY rarely and more often than not it's down to poor cymbal technique. I suspect that the zildjian on the right was a manufacturing defect due to the way the cymbal cracked (you don't often see a crack start in the middle) but as I'd had the cymbal for a number of years, I felt it had done what it was supposed to do. At the end of the day, we're hitting these cymbals with force (though with correct techniuque most of the time) and I personally don't expect cymbals to last forever.
I'm the first to admit that my cymbal technique isn't perfect, when I'm playing a gig and really getting into it, I hit my cymbals way harder than I should. The end of our set has a song I love playing and has a gigantic ending with lots of crashes. I've only ever cracked 3 cymbals in 13 years of playing which is one every 4 years so I'd say I'm doing okay (but not brilliant). Fp200a sensor driver windows 7 64. If you play carefully with correct technique, there's no reason that cymbals shouldn't last forever, for the sake of your cymbals (and your wallet) brush up on correct cymbal technique (article coming soon).
However, if you have cracked a cymbal you need to make a decision as soon as you notice the crack. Do you drill/cut it and hope that the crack will stop(and potentially kill the sound of the cymbal) or let the crack take it's course and replace when the cymbal is virutally unplayable. Cracking cymbals is certinaly not big, clever or an indication that you're some kind of drum playing god. By all means enjoy your playing, but remember that decent cymbals run at ~£130 depening on make and size.
