Hello, I am looking for a licensed New Jersey Professional Engineer to evaluate an inground vinyl pool wall collapse in South Jersey. The contractor drained all of the water out of my inground vinyl pool during work in 2025. The pool wall later collapsed, leaving the pool unusable and causing major damage. My homeowner’s insurance claim was denied, and the denial referenced poor workmanship. I am trying to determine whether fully draining the pool, improper workmanship, soil pressure, hydrostatic pressure, or failure to properly protect the pool structure contributed to the collapse. Because I am working with limited funds, I would like to start with the most cost-effective option first, such as an initial consultation, site inspection, or limited written opinion letter. If neede...

I have a wireless-power-transfer concept that hinges on a well-tuned antenna, and I want to prove its performance inside CST Studio Suite through a full electromagnetic simulation. The goal is clear: design, simulate, and refine the antenna until the S-parameters, gain, and efficiency meet the power-transfer targets I will share once we start. You will start from my rough dimensions and operating frequency, build a clean 3D model in CST, run the frequency-domain solver, and iterate the geometry or matching network as needed. Along the way, I expect you to explain the choices you make—material settings, boundary conditions, mesh strategy—so I can replicate or adjust the work later. Deliverables • CST project file with all simulations completed • Exported results ...

I’m finishing a pro-touring 1977 Trans Am and need a matching pair of front wheels to complement the 18x12 billet Snowflakes already on the rear. The spec is straightforward: 18 x 10.5, 5 × 4.75 bolt pattern, carved from aluminum billet in the classic Snowflake style that YearOne offered before they were discontinued. The car runs a Detroit Speed front subframe, so I’ll need a custom offset/backspacing; I can pull precise measurements once we start, but guidance on the best way to gauge them is welcome. I have a clear reference photo of the exact Snowflake pattern I want, so you won’t be guessing on spoke shape or pocket depth. What I’m looking for is a fabricator or small shop with access to CNC milling/lathe equipment (or equivalent) who can model the wheel...

I have a clear concept for a mechanical cloth-knotting tool and now need it laid out professionally in AutoCAD. The device’s core purpose is to create consistent knots in multiple threads at once, so all geometry, tolerances and part interfaces have to accommodate true multi-thread handling without tangling or mis-feeds. Your job is to translate my sketches and notes into a complete digital package: a fully detailed 3D model, clean 2D fabrication drawings with dimensions and tolerances, and a short animation or exploded view that illustrates the knotting sequence. If you prefer to prepare the solid model in another package first (e.g., SolidWorks or Inventor) and then deliver the final DWG/DXF set, that’s fine as long as the AutoCAD output is flawless. Deliverables • P...

I will share detailed drawings of small brass and copper parts used inside MCB / RCB assemblies, together with the exact material grade and the tolerances each feature must hold. Your assignment is to turn that data into a full progressive-die design that delivers three things at once: minimal scrap, reliable bends and forms, and a price-conscious build. The strip layout must be creative—far beyond the basic local market approach—so every station adds measurable value while keeping unusable web to an absolute minimum. I am especially interested in new ways to shorten changeover time and to validate the design before steel is cut. The solution has to incorporate: • Quick-change tooling features for rapid die set-ups • Advanced simulation for design validation (spri...
