MANUFACTURING CAPABILITIES
The shop behind the champions.
Every Team Whyachi robot is designed, cut, machined, and welded under one roof at Westar Manufacturing. That same shop builds parts for other people — from one-off prototypes to production runs, in metal, plastic, stone, and glass.

ABRASIVE WATERJET
Precision cutting, zero heat.
Ultra-high-pressure abrasive cutting stream
Achievable precision on a single setup
Maximum material we can cut clean through
Cold cutting — no warping, no hardening
What waterjet does best
An 87,000-psi stream of water and garnet abrasive slices through almost any material without heat. There is no heat-affected zone, no slag, and no hardened edge — so parts come off the table dimensionally stable and ready for the next operation. One machine cuts virtually any 2D profile, which makes it ideal for prototypes, fixtures, and the kind of short, precise runs that keep our own robots competitive.
We've cut robot armor and weapon rings since bringing waterjet in-house in 2008 — and we cut the same way for our customers.
Materials we cut
DESIGN FOR WATERJET
Getting the most out of the cut
No heat distortion
Because the stream cuts cold, parts come off the table ready to use — no heat-affected zone, no warping, and no hardening along the edge to machine away later.
Tolerances
Plan for ±0.005" on most work and ±0.002" on thinner material. The cutting stream is about 0.030" wide, so add a small radius to inside corners rather than a sharp point.
Holes & detail
Minimum practical hole diameter is roughly equal to material thickness. Fine lettering, logos, and intricate profiles cut as easily as straight lines — there is no tooling to change.
Material savings
Any flat profile can be nested tightly on a single sheet, so prototypes and short runs are fast and economical with very little scrap.
MACHINING & FABRICATION
More than a cutting table.
Waterjet is where most parts start. From there we machine, weld, and assemble complete components in-house — the full path from raw stock to finished product.
CNC machining
Tight-tolerance milling and turning to finish waterjet blanks or machine parts from solid.
Welding & fabrication
Structural and precision welding, chassis, frames, and weldments built to spec.
Assembly & finishing
Sub-assemblies, hardware, and finishing — parts arrive ready to install.
DEFENSE & REMOTE VEHICLE SYSTEMS
Combat-proven engineering, off the arena floor.
The same instincts that make a robot survive in the BattleBots arena — rugged drivetrains, reliable remote control, parts that don't fail under abuse — translate directly to the field. We've designed and built remote-control vehicle systems for the U.S. military, including remote-steering conversions for HMMWVs and a purpose-built remote buggy, with on-site installation and support at Fort Campbell.
Have a part you need made?
Send us a drawing, a sketch, or just a description. The team that builds champions will tell you how to make it — and cut it. Deep industrial and B2B work runs through our sister company, Westar Manufacturing.
