Manual Machining
For one-off precision work, prototypes, feature-add, and sustainment repairs where CNC setup isn't justified. Kingston manual lathes staffed by experienced machinists for jobs that need a human eye more than a G-code file.

Frequently asked questions
When would I choose manual over CNC turning?
When quantity is 1 and CNC programming/setup isn't justified, when the part is a repair or feature-add on existing material, or when reverse-engineering a worn sample. Manual is faster on true one-offs; CNC is faster at quantity 2+.
Do you reverse-engineer discontinued oilfield parts?
Yes — routine sustainment work. Send a worn sample; we CMM-measure, PMI-verify the material, infer tolerances, and produce replacements with full traceability. Common for downhole tools, wireline tools, and API-adjacent hardware.
What tolerances can you hold on manual work?
±0.001" is standard practice with experienced machinists on Kingston lathes. Tighter with careful setup and gauge blocks. Every critical dimension inspected and documented.
What's your turnaround on one-off manual work?
For existing customers with stocked material: same-day to next-day is realistic. New customers with new material: 3–7 days. Emergency rig-down: prioritized on the schedule.
Do you take walk-in or field jobs?
Yes — Montgomery County / Walker County / North Houston customers can drop off parts. Emergency parts get worked into the schedule. Call (936) 291-7827 first so we can plan the shop-floor pass.
What manual equipment do you run?
Kingston manual lathes for precision turning, plus Bridgeport-style manual mills (see Manual Milling for details). All operated by experienced machinists with decades of practice.
