Heat-treated oil well slips and reins, machine repair, and custom parts for manufacturers. A family-owned shop in the birthplace of the American oil industry, where the person who answers the phone is the person who runs your part.
Our core product. Slips and reins machined in-house, heat-treated for strength, and pressure tested. Operators across the Appalachian Basin run them because they grip and they do not fail.
Bring us the worn or broken part. We reverse-engineer it from the sample, repair it where that makes sense, or make a new one from scratch when it doesn't.
CNC and lathe work for regional manufacturers, from one-off replacement parts to complete purpose-built machines. We build equipment for Titusville's ribbon factory, and have for years.
A slip has one job: hold the load in the well without slipping, cracking, or deforming. We heat-treat every set, then pressure test them. When we put ours up against competitors' slips under the same test, ours held after the others gave out.
Test figures and photos of the comparison to be added once the shop confirms the numbers.
Honest numbers so you know up front whether a job fits. If your part is outside these limits, ask anyway; we work with partner shops in the region for the rare job we can't take.
Highlighted values are placeholders to be confirmed with the shop.

Crawford Machine is owned by Bill Webb and run day to day with his son BJ Webb. When you call, you talk to the person who will run your part. No sales desk, no hand-offs.
Titusville sits a mile from the Drake Well, and this town has been making oilfield machinery since 1860. We are part of that lineage: a small shop that serves the producers, service companies, and manufacturers of northwest Pennsylvania, and ships anywhere a part needs to go.
