This structural studio is completely separate from general residential architecture houses or consumer toy manufacturing. We specialize in the mechanical drafting and geometric optimization of low-gravity mobile frames, non-motorized testing platforms, and aerodynamic wooden or composite shells utilized in kinetic engineering experiments and structural stress testing.

Ordered by latest update — all threads are active.
The CNC shop confirmed ±0.05 mm on the main rail holes. We should update the assembly drawing to reflect the new clearance spec before the next test run.
Vacuum bagging pressure increased to 0.9 bar. The second test panel showed no delamination after 12 thermal cycles. Ready to proceed with full shell layup next week.
The aluminum mold halves have been polished and sealed. First layup scheduled for Thursday. We'll document the peel-ply texture for the FEA correlation report.
All four load cells read within 0.2% of the certified weights. The DAQ script has been updated to log at 100 Hz. Ready for the static load test once the frame is assembled.
We have the low-speed tunnel on March 12 from 09:00 to 16:00. Maximum model size is 1.2 m length. The beech shell and MK-II frame fit within the envelope. I'll prepare the mounting adapter.
Our studio focuses on mechanical drafting and geometric optimization for kinetic engineering — not residential architecture or consumer goods.
Every frame is drafted for low-gravity mobile platforms and non-motorized testing. We don't adapt house plans or toy molds — we engineer from the load path up.
Beech laminates, carbon-kevlar hybrids, and 6061 aluminum each require distinct joint design and stress modeling. Our drawings reflect real fabrication constraints, not generic templates.
Prototypes are built for wind tunnel and impact rigs. Data from accelerometers and strain gauges feeds back into the next revision — no assumptions, only measured results.
Each structural studio capability is built around measurable outcomes for prototype validation and mechanical testing.
Truss and monocoque layouts are refined through iterative FEA to reduce material mass without compromising the 3.2× safety factor required for low-gravity test runs.
Chassis are engineered for gravity-assisted acceleration on inclined tracks, eliminating drivetrain variables from aerodynamic drag and structural load measurements.
Carbon-kevlar hybrid layups are tailored to specific load paths, with documented ply orientations and vacuum-bagging protocols for repeatable test results.
Steam-bent beech laminates provide natural vibration damping, yielding cleaner accelerometer and strain-gauge data during low-speed wind tunnel runs.
Quick-release brackets and standardized hardpoints allow rapid reconfiguration of instrumentation payloads between test sessions without rework.
Platforms are built to withstand repeated impact and torsional loading up to 8 kN, enabling both destructive and non-destructive validation of joint designs and laminate schedules.
We specialize in low-gravity mobile frames, non-motorized testing platforms, and lightweight mechanical chassis for kinetic experiments. Our work is strictly structural and mechanical — we do not design residential architecture or consumer toys.
Yes. We provide detailed mechanical drafting and geometric optimization for prototype frames, aerodynamic shells, and composite monocoques. Deliverables include dimensioned drawings, material callouts, and assembly notes suitable for fabrication.
Our primary materials are 6061 aluminum, carbon fiber, Kevlar, and steam-bent beech plywood. We select materials based on stiffness-to-weight ratio, damping characteristics, and compatibility with the test environment.
We design platforms specifically for structural stress validation, including destructive and non-destructive testing. Our composite monocoque test platform, for example, is built to withstand repeated impact and torsional loading with a predicted safety factor of 3.2× under maximum design load.
