Do I need to send the original part?

For anything with a tooth form or a spline, yes — or the mating part. Photographs and overall dimensions are enough to quote, but not enough to cut teeth.

How accurate can a reverse-engineered part be?

As accurate as the references we can measure. Bores and faces are held to the tolerances on the approved drawing; a heavily worn tooth form is reconstructed rather than copied.

Can you tell me what steel it is?

We test chemistry and hardness and report what the sample is. If the original grade is unavailable, we propose an equivalent and state the difference.

The drawing you approved, the part, a dimensional record, and the material and hardness results where they apply.

Measure the sample.
Then cut metal.

Some parts arrive with nothing but the part itself: no drawing, no material certificate, no part number. We measure it, establish what it is made of, and turn it into a drawing and a route you can approve.

When there is no drawing

Older equipment, a workshop that has closed, an archive that was never digitized. The part in your hand is the only reliable record, and it is enough — provided the worn surfaces are not mistaken for the original ones.

What we measure

Bore, faces, keyways and splines; tooth count, module and helix angle on gears; runout and concentricity against the datums the machine actually uses. Tooth form is checked on the gear tester, not scaled off a photograph.

Material, established not guessed

Where a certificate exists we work from it. Where none does, a sample is tested for chemistry and hardness, and the substitute is agreed with you before machining.

The limits of a worn sample

Wear is not symmetric, so the dimension chain is built from the references that did not run: the bore, the mounting face, the unworn flank. If too little is left, the mating part supplies the missing numbers.

Approval before cutting

The drawing goes to you first. Tolerances, material and heat treatment are agreed on paper; only then is the route card issued and the first cut made.

Send photographs and the main dimensions.

We reply with what we can measure, what we cannot, and the questions we still need answered before quoting.
