If your pegs are too loose and keep slipping, try firmly pressing the peg in while spinning the peg. If this does not work, some cellists use peg compound or a substance called peg drops to keep pegs from slipping (peg drops, also known as peg grip, are used solely for slipping pegs). There are two types of peg compounds: liquid and powder. Liquid compounds can be mixed together before use; powder compounds must be mixed with water before use.
The string bed of the cello is designed to hold the strings at a slight angle so that they do not touch the side of the neck. This allows the strings to vibrate without damping out their sound. However, if the peg holes are not drilled deep enough, or if the cellist uses pegs that are too large, the strings will touch the side of the neck when played at certain points along their length. When this happens, the vibration of the string is damped out completely, which means that it cannot produce sound. In this case, the only way to fix the problem is to drill deeper holes or use smaller pegs.
Drilling deeper holes is not a practical solution since this would weaken the body of the cello. Using smaller pegs is possible but impractical since a cellist needs a lot of flexibility in his or her fingers to play the instrument well.
The best solution is to use pegs that are just right for your cello.
If this does not work, some violinists use peg compound or a substance called peg drops to keep pegs from slipping (peg drops, also known as peg grip, are used solely for slipping pegs). There are two types of peg compounds: liquid and paste.
Peg drops are substances that can be bought at any hardware store. They come in a spray can and usually contain polyvinyl alcohol. Violinists mix peg drops with water and apply the mixture with a brush on the outside of their shoes. The purpose of the peg drop is to create a slippery surface on which to stand. There is no scientific evidence indicating that using peg drops on pegs will damage them.
Peg compounds are not recommended for novice shoe wearers because they may not remove all the compound quickly enough before walking on the peg. Also, the mixture could dry out and become hard over time.
If you choose to use a compound, make sure it's a non-toxic one and doesn't contain any chemicals that might harm the wood of your instrument.
In conclusion, pegs can be fixed in three ways: shaving, dipping, or spraying with a compound. It is important to understand how each method works before attempting it yourself. Don't forget to wear protective footwear when working with tools!
Pegs can sometimes fail to keep your string in place because the peg itself has worn out and will no longer grip well in the hole. This sort of issue may be resolved by removing the peg and very carefully roughening up the surface with very fine grain sandpaper. Typically, one gentle swipe would suffice. You should only do this with clean, dry hands and a clear view of the area you're working on.
If you choose to replace the peg, there are several options available. The most affordable way to fix this problem is with some fine-grain rubberized guitar picks. These can be found in any music store and are a great alternative if you have trouble playing the violin for long periods of time.
If you'd like to take things a step further, here are two high-end replacements that will really polish your violin up: Fivarina PEGS and BOB EVANS. Both are premium products that will provide you with years of quality performance.
Finally, if all else fails, visit your local violin shop and they should be able to help you out. Most shops carry spare parts so it shouldn't cost much to get everything fixed up!
