Finishing turned wood without leaving the lathe

On the lathe, the finish goes on with the piece turning: Cellulose Sanding Sealer for a quick, smooth base, de-nibbed with 220, then High Build Friction Polish on a lint-free cotton cloth, a carnauba stick on its edge and a burnish with a dry cloth. Melamine Lacquer Gloss, a hard semi-gloss resistant to heat and water, for a lamp base or a display bowl, revived with Burnishing Cream; Food Safe Oil or Pure Tung Oil for bowls and boards that meet food; Wax Cutting to take down a gloss that is too bright. Allow two hours for a bowl.

Why the lathe changes everything

The piece turns, the finish follows

A turned piece is rarely finished at the bench: it is finished on the lathe, while it turns, with products made for that. The rotation spreads the product in a thin, even layer, and the heat of friction does the rest. That is the move Mylands makes Cellulose Sanding Sealer for, a fast-drying base that fills the pores and smooths the surface, and High Build Friction Polish, a turning shellac that goes on with a cloth and is polished with a carnauba stick.

Four routes, depending on what the piece is for. Friction polish for the deep gloss of a bowl or a display box. Melamine Lacquer Gloss, a hard semi-gloss resistant to heat and water, for what gets handled or sits next to a lamp. Food Safe Oil or Pure Tung Oil for what receives food. Sealer and wax for a piece soft and matt to the touch. Cellulose Thinners thins the sealer and the melamine lacquer, and cleans the brushes.

The method

A bowl in friction polish in six moves

A warm, dry workshop: shellac clouds in humidity. Piece mounted on the lathe, last cut made.

  1. 01

    Sand through the grits to 180

    With the piece turning, 120 then 150 then 180; then with the lathe stopped, a last pass along the grain to erase the circular scratches, which shellac would magnify. Dust off.

  2. 02

    Seal with Cellulose Sanding Sealer

    With a cloth or a brush, piece stopped, one thin coat; it dries fast. Thin with Cellulose Thinners if the product thickens. Once dry, de-nib with 220 until the surface feels glass-smooth: this sanding is what makes the final gloss.

  3. 03

    Charge the cloth with High Build Friction Polish

    A folded lint-free cotton cloth, a small amount of polish, the piece turning. Press firmly and keep moving: the heat of friction sets the shellac. Recharge in small amounts until you reach the build you want.

  4. 04

    The carnauba stick

    Once the build is there, present the edge of the carnauba wax stick against the turning piece, without forcing: a fine veil is laid down.

  5. 05

    Burnish with a dry cloth

    A clean, dry cloth pressed against the turning piece, up to a mirror gloss. To go further, a drop of Burnishing Cream on a cloth lifts the lustre again; to quieten it, Wax Cutting.

  6. 06

    Clean up, let it harden

    Sealer brushes and cloths in Cellulose Thinners, away from any flame, window open. The piece can be handled at once, but shellac stays sensitive to heat and alcohol: coasters.

Four pieces

Four turned pieces, four finishes

01

1. The ash bowl in friction polish

Open-pored ash asks for careful sealing: Cellulose Sanding Sealer, de-nib with 220, then High Build Friction Polish on a cloth, carnauba, burnish. A deep gloss that shows the grain. A display bowl, not a salad bowl: shellac dislikes heat and alcohol.

02

2. The oak lamp base in melamine lacquer

Handled, dusted, warmed by the bulb: Melamine Lacquer Gloss, a hard semi-gloss resistant to heat and water. Sealer de-nibbed with 220, then 2 to 3 thin coats 3 to 4 hours apart, de-nibbed between them. Burnishing Cream to raise the lustre once hard.

03

3. The beech salad bowl in food-safe oil

No sealer, no shellac: bare wood sanded to 180 at most, Food Safe Oil, tasteless and odourless, generously, 5 to 10 minutes, wipe off, nothing left wet after 20 minutes, three coats 12 to 18 hours apart. Pure Tung Oil, resistant to food and acids, suits it too.

The choice

Which finish for which piece

FinishLookForWorth knowing
High Build Friction Polish over sealer Mirror gloss, warm Bowls, boxes, spinning tops, display pieces Shellac: dislikes heat and alcohol; repairable, new coats melting into old ones
Melamine Lacquer Gloss Semi-gloss, hard Lamp bases, handles, pieces that get handled Resists heat and water; cool dry atmosphere, or it blooms white
Food Safe Oil, Pure Tung Oil Matt, bare wood Salad bowls, platters, boards, fruit bowls Tasteless and odourless; a maintenance coat when water stops beading
Sealer and Wax Clear Soft matt, silky Boxes, decorative objects No wet cloth; wax once or twice a year
Acrylic Sealer, Pure Tung Oil Matt or satin Toys Acrylic Sealer complies with EN 71; Pure Tung Oil non-toxic, usable on toys

Raising or lowering the sheen: Matt, satin or gloss on wood. The whole selection: Wood turning.

To avoid

What ruins a turned piece

  • Sealer left un-sanded. The friction polish or the lacquer follows every raised grain: the surface is dull and rough. De-nib with 220 to a glass feel.
  • Too much polish on the cloth. It drags, ropes and streaks. Small amounts, firm pressure, continuous movement.
  • The cloth held still on the piece. It burns the shellac into a dark ring. Always keep moving.
  • Cellulose Thinners near a flame or a heater. A flammable solvent: window open, no flame heating in the workshop.
  • Shellac on a salad bowl. What touches food gets Food Safe Oil or Pure Tung Oil, nothing else.
  • Lacquering in a damp workshop. A milky white bloom on melamine lacquer as on shellac: warm and dry, always.

Frequently asked

Your questions, our answers

Can friction polish be used off the lathe?

It is designed to be applied with the piece turning, the heat of friction setting the shellac. Off the lathe, you move to traditional French polishing with a cotton rubber: see French polishing with shellac.

How do I get more gloss, or less?

More: Burnishing Cream, very mildly abrasive, revives the lustre of friction polish and melamine lacquer once hard. Less: Wax Cutting, a pumice wax, lowers the sheen of an already polished piece; or, on shellac, a pass of fine wire wool two days after the last coat.

Why does my lacquer or shellac turn white?

Workshop humidity, trapped in the film, gives that milky bloom. Work in a warm, dry atmosphere, and wait for a dry day rather than forcing it: on a piece that has already clouded, you de-nib and lay a fresh thin coat, in the dry.

Which finish for a bowl that will really be used?

Food Safe Oil, tasteless and odourless, or Pure Tung Oil, resistant to water, food and acids: three coats 12 to 18 hours apart, all excess wiped off after 20 minutes, then a coat on a cloth as soon as water stops beading. Never shellac or lacquer on what touches food.

Is Cellulose Sanding Sealer compulsory?

Under a friction polish or a lacquer, yes: it fills the pores, dries fast and gives, de-nibbed with 220, the smooth surface a gloss needs. Under an oil, no: oil wants bare wood, sanded to 180 at most, so that it can penetrate.

“The lathe makes the shape; the cloth, with the piece turning, makes the light.”
