Practical, no-jargon guides for getting custom and replacement parts made — how to order without CAD, reverse engineering, choosing materials, reading a quote, and sourcing safely from China.
Practical, no-jargon guides for getting custom and replacement parts made — how to order without CAD, reverse engineering, choosing materials, reading a quote, and sourcing safely from China.
You don't need engineering software to get a part made. Start here.
Sketch, photo or sample — what to send to start a quote.
Turn clear photos + one dimension into a real part.
What helps — and what's optional — for an accurate quote.
Understand setup, material, tolerance and finish costs.
Why single pieces and small batches are welcome here.
When the part is discontinued, back-ordered or the supplier is gone.
How to reproduce a part when the maker is gone.
No drawing needed — from the worn part itself.
Reproducing obsolete pump components to spec.
Remaking obsolete engine components from a sample.
Recreating worn or obsolete gears to original spec.
Reproducing obsolete hydraulic components safely.
Remaking obsolete plastic parts with no tooling.
Bringing legacy equipment back to running order.
Recreating a part when there's no drawing — only a sample, a photo or a broken component.
The measure-rebuild-confirm-machine workflow.
Reproducing cast parts from an existing sample.
How to describe a mystery component for remaking.
Matching metric, UNC/UNF and odd legacy threads.
Recovering original dimensions from a worn shaft.
Low-volume plastic reproduction options.
Technical guides on hydraulic and pneumatic thread standards — BSP, NPT, ORFS, JIC — and when you need a custom adapter.
Parallel vs tapered BSP — how to identify each type, sealing methods, and what happens when they're mixed.
BSPP or BSPT to NPT — any size combination, carbon steel or 316 stainless, 1 piece minimum.
JIC 37°, ORFS, SAE ORB — any combination machined to order.
Choosing the right metal and understanding tolerances and finish.
Which to choose, in plain language.
The area-ratio rule, galvanic corrosion, galling — and when to isolate or switch material.
Strength-to-weight, corrosion and cost compared.
Anodizing, passivation, black oxide & more.
What ±0.1 mm actually means for your part.
How to vet a supplier, protect your design and pay safely.
