Research. Build. Prove. Under one roof.
Illyra JSL is a tool development company. We take a specific, repeated task in one trade and carry it from the jobsite to a tested, buildable tool, without handing it off between agencies, shops and labs.
Jobsite research
Ride-alongs, time studies, task selectionWe spend time on real jobs, time each step, and pick the one that still costs a crew a person, an hour or a callback.
Mechanical design
CAD, load and failure-mode analysisEvery concept is modeled for the loads it will see on site, and for the ways it could slip, bend or mark a finished surface.
Simulation
Interactive models before metalWe build working digital models to test geometry, ranges and set-up before anything is cut.
Prototyping
Fast builds in the Chicago areaPrototypes are built close to the people who use them, so a design can change between one site visit and the next.
Bench testing & validation
Overload, slip, drop and surface testsNothing leaves the shop without passing our own bench tests. Results are published as tested, never rounded up.
Field trials
Prototypes on paying jobsField Program pros use our prototypes on their own work and tell us what's wrong. If it doesn't save real time, it doesn't ship.
From ride-along to production.
Each stage has one job: kill weak ideas early and make strong ones cheap to build. If a tool doesn't save real time on a paying job, it doesn't ship.
