Oiling a wooden handle

A turned wooden handle, like the beech one on our bell, is not finished the way a table or a floor is finished. It has no hard lacquer sitting on top of it. That is deliberate, since a handle gets gripped and warmed by a hand far more than it gets set down, and a bare, oiled surface feels better in the palm than a sealed one ever does. It just means the wood needs a small amount of care that a varnished handle would not.

Why beech takes oil well

Beech is a close-grained wood, meaning its fibres sit tight together with very little of the open pore structure you would see in oak. That tightness is what lets it be turned smooth on a lathe and take a fine finish, and it is also why oil sinks in evenly rather than pooling in patches. Other close-grained woods, such as maple or cherry, behave the same way. Open-grained woods, like oak or ash, drink oil unevenly and need more of it to look right. Beech does not.

Mineral oil, not vegetable oil

Use a food-safe mineral oil, sold as butcher block oil or board oil, rather than anything from the cooking oil shelf. Vegetable oils, olive oil included, are organic and will eventually go rancid inside the wood, which shows up as a faint sour smell that will not wash out. Mineral oil is inert. It does not oxidise, it does not spoil, and it has no smell to begin with or after. A small bottle lasts a long time, since a handle this size takes only a few drops at a time.

How to oil it

1. Make sure the handle is clean and completely dry.
2. Put a few drops of mineral oil onto a soft cloth, not directly onto the wood.
3. Rub it into the grain, working along the length of the handle rather than across it.
4. Let it sit for ten to fifteen minutes, then wipe off anything that has not soaked in.
5. Leave it somewhere it will not be handled for an hour before use.

Do this every one to three months for a handle in regular use, or whenever the wood starts to look pale and dry rather than warm. There is no need to oil it on a fixed schedule if it still looks and feels right.

The furry signal

After washing, run a thumb along the handle. If it feels slightly rough or fuzzy rather than smooth, that is the wood grain lifting from contact with water, a normal reaction and not damage. It is also a reliable sign that the handle is due for oil. A light sanding with fine paper, 320 grit or finer, worked gently with the grain, will knock the roughness back down before you oil it. Skip the sanding if the roughness is only slight; oil alone often settles it.

What to avoid

Never soak the handle or leave it standing in water, and never put it through a dishwasher. Both will drive moisture deep into the wood faster than it can dry out again, and repeated soaking is how a turned handle eventually splits or loosens at the joint. Wipe it with a damp cloth instead of submerging it, dry it straightaway, and keep it away from direct heat such as a radiator or a sunny windowsill, which dries wood out just as surely as water damages it, only more slowly.

A little oil now and then is the entire routine. Keep to it and the handle stays smooth, keeps its colour, and only gets better to hold with age.
