A setter's bench test: what employers watch

A bench test asks a setter to set one stone, or a short run of stones, at a bench the employer provides, while someone watches the hands. It is a practical examination, not a conversation: the employer is looking at how the stone is seated, how the metal is moved and how the bench is left. The tools that do that work, the punches, pushers, burnishers and millgrain wheels that place a stone and keep it there, are the same tools a reference such as the setting bench describes by shape and purpose.

What does a bench test for a stone setter actually ask?

Most bench tests give the candidate a prepared piece and a stone, then ask for a finished setting. A typical brief is a round brilliant in a collet or a claw setting, or a small channel run of three or four stones. The employer supplies the metal, the stone and the bench; the candidate supplies the hands.

The test is timed, but the time is rarely the point. What is being read is the sequence: whether the seat is cut before the stone is pressed in, whether the stone sits level, whether the claws or the bezel are drawn down evenly, and whether the finished surface is burnished rather than filed flat. A setter who rushes a claw over a stone and cracks it has failed the test whatever the clock says.

Some employers add a second task: a re-tip, a re-polish or a repair on a customer's ring. That is closer to the daily work in a repair shop than a clean setting job, and it tests judgement about someone else's metal.

Which hand tools does a setter bring to a trade test?

Employers differ. Some provide a full bench; others expect the candidate to arrive with a roll. The safe assumption is that the candidate brings the small tools that are personal to the hand, and uses the employer's bench, vice and lighting.

A working roll usually holds:

• gravers, scorpers and burins for cutting the seat and cleaning the edges
• a bezel pusher and a burnisher for drawing metal over a stone
• a set of punches for opening claws and moving metal
• a millgrain wheel and its handle for finishing an edge
• a small hammer, a bench knife and a loupe
• a selection of escapement files and a slip stone for the graver edge

The bench itself, the peg, the pin, the clamps and the shellac, is normally the employer's. A candidate who turns up with a full roll and no way to sharpen a graver will be noticed. The edge is the tool; a blunt graver cuts nothing and skids across a seat.

How is a bench test scored, and what counts as a fail?

Scoring is usually a short list of observable points, marked by the person who set the test. The common ones are:

1. The stone is secure. It does not move under a fingernail or a loupe.
2. The stone is level and correctly oriented. A table that tilts is a fail on a visible stone.
3. The metal is moved, not cut away. Claws and bezels that have been filed thin to make the stone fit are a fail.
4. The finish is clean. No file marks, no flat spots, no scratches across the polish.
5. The bench is left tidy and the tools are put away.

A fail is usually one of three things: a loose stone, a damaged stone, or a setting that cannot be repaired without remaking it. Time overrun matters less than a broken stone, because a broken stone is a cost to the employer and a lost customer.

What the employer is really watching

The test is a reading of habit. An employer watches where the candidate's hands rest, whether the piece is supported before the punch lands, whether the loupe is used before and after, and whether the candidate stops when something is wrong.

A setter who says the seat is too deep, or that the stone has a feather, is showing more than a setter who finishes quietly and hands over a cracked stone. Bench work is small and slow, and the person hiring knows that the first sign of a good setter is the willingness to stop.

Under the Equality Act 2010, an employer must make reasonable adjustments for a disabled candidate during a trade test, which can include extra time, a different bench height or a different chair. A candidate who needs an adjustment can ask for it before the day.

What the contract says after a passed test

A passed bench test usually leads to a trial period rather than a permanent offer. In the United Kingdom, a statutory trial or probation period is a contractual matter, not a statutory one: the law sets the notice and pay rules, not the length of probation. A typical arrangement is a three-month probation with a short notice period on both sides, then a review.

Pay is normally PAYE, with National Insurance deducted at source and pension auto-enrolment after the qualifying period. Working time, rest breaks and holiday entitlement follow the Working Time Regulations 1998. A setter on a bench is usually paid hourly or on a salary, and overtime is a contractual term, not an automatic right.

What to practise before the day

The test rewards repetition. A setter who has set the same collet twenty times at their own bench will read the metal faster than one who has read about it. Practising a claw setting on scrap, then a bezel, then a channel run, builds the sequence that the employer is watching for.

The tools matter less than the order they are used in. A graver, a pusher and a burnisher will set a stone if the seat is right; no tool will set a stone if the seat is wrong. A candidate who can explain why a seat was cut a certain way is already ahead of one who can only show the finished ring.

Questions to ask at the end of the test

A bench test is a two-way reading. The candidate can ask what the daily mix is, whether the bench is shared, what the repair turnaround is, and who sharpens the gravers. The answers say as much about the workshop as the test says about the candidate.

A short, honest test with a clear brief is a better sign than a long one with no brief at all. The employer who watches the hands is also showing the candidate what the bench will be like on a normal Tuesday.
