Submit a drawing

The column on the right is the estimator's checklist. It is what has to be on the sheet before a number can go on it. Lines close as you fill them in, and you can send the sheet with lines still open - it will just come back as a phone call first.

The part
PDF, DXF or STEP. Flat patterns are not required - we develop them.
If there is no drawing yet, say what the part does and roughly how big it is. We have quoted from worse.
Or the duty, and we will call the grade.
How it has to come out
Mark the ones that are doing work. Everything unmarked is held to the shop standard on the front page and quoted at that cost.
Where and when

Why each line is on the sheet

None of it is form-filling for its own sake. Each line is a decision somebody in the shop otherwise has to guess at.

  1. A drawing or a model

    PDF, DXF or STEP. Flat patterns are not required - we develop them, and we would rather develop them than inherit one built to somebody else bend allowance.

  2. Material and grade

    Or describe the duty and we will call the grade. Tell us if a specific mill or a specific certificate is required, because that changes the lead time before it changes the price.

  3. Quantity, and whether it repeats

    A run of four prices differently if there are forty behind it. Say so and the tooling gets amortised properly.

  4. The tolerances that matter

    Mark them. Anything unmarked is held to the shop standard published on the front page of this site, and quoted at that cost.

  5. Finish

    Mill, blast and prime, painted, or hot-dip galvanized. Galvanized work adds roughly two weeks and needs venting and draining designed in.

  6. Delivery

    Where it goes and the date it has to be on site. If the date is the constraint, say that first - it changes how the job is routed.
