Cello Tuning

[tony1941]

I have just bought a second-hand cello (just in case I can ever learn to play it) and am having trouble with the tuning pegs slipping. What is the recommended method of increasing the friction?? The engineering solution would be to tap them in with a small soft hammer, but I think the problem really lies with the surfaces.
Thanks for any suggestions.

In order to keep the tuning pegs from slipping, you will need to apply inward pressure on the tuning pegs toward the cello head as you turn the tuning peg, but not using so much force that you may damage the peg hole. Tuning pegs are tapered hence the inward pressure will ensure that they stay in position once released. The tuning pegs must be made of ebony, and precisely fitted, or the instrument will constantly slip out of tune.
