I have a batch of precision metal parts that must be produced on a lathe to very tight tolerances. All work is on metal stock only—no wood or plastics. The tasks involve three core operations: turning multiple diameters, facing surfaces perfectly square, and cutting both internal and external threads exactly to the drawing specifications. I will provide detailed PDFs and STEP files that call out ±0.02 mm tolerances and surface-finish requirements. You will take the project from raw bar to a fully inspected, production-ready component. That means setting up the machine, choosing the right tooling and inserts, dialling in speed/feed and coolant, running in-process micrometer checks, and completing a final inspection before parts leave your shop. Consistency across the small-to-...

I’ve already sketched and modelled a sleek, pen-sized instrument that fuses four everyday essentials for medical-device reps: a fine-tip pen, a permanent marker, a rechargeable laser pointer, and a concealed, auto-retracting ceramic blade for opening cartons. Now I need to see it come to life in the form of one or two fully working prototypes that prove every feature actually functions. Functionality and quality are my top priorities. The prototypes have to write cleanly, shine a steady laser, and retract the blade the instant pressure is released. To make that viable all day, battery life and a convenient USB-C (or similarly compact) charging solution are non-negotiable. Safety is equally critical: the laser must include recessed button for activation, and the ceramic blade mechani...

I need a collection of fully-parametric wild animal 3D designs that can be cut straight from sheet metal on a CNC laser. The key is that every profile scales cleanly when I change material thickness or overall size, so please build the models with global parameters, equations, or design tables in SolidWorks. A clean STEP export alongside the native files will let me reuse them in other CAM packages. Think bears, wolves, eagles, stags—strong, recognizable shapes that translate well to single-piece cutouts without fragile bridges. Each file must arrive as a flat 2D body in the correct plane, with closed, knife-edge contours and zero overlaps so my nesting software accepts them without extra cleanup. Kerf compensation and tabbing are handled on my end; your task is the geometry. Deliv...

I am looking for an engineer or team that has already completed full-scale retrofits on large-format CNC equipment and can bring an HB03/TS150 JUARISTI up to today’s standards.

Project Brief: Stealth-Modified Automatic Parking Disc (Certified for Public Road Use in Germany) Project Goal: I want to technically modify a certified electronic parking disc approved for use in Germany (must have an official certification number and ECE approval), so that it continues to automatically update the displayed parking time even after the vehicle has been parked. This modification must be invisible and undetectable from the outside, meaning the device must look and behave like the original product to any observer or parking enforcement officer. Background: Standard electronic parking discs are designed to detect when a vehicle is turned off and then freeze the display at the next permissible half-hour mark. This allows parking enforcement to determine how long the car has b...

I want to turn my stock WowWee MiP into a fully-independent companion with far more capability than the original phone-controlled toy. The big push is to give it functional robotic arms—servo-driven, proportional, and strong enough to perform simple pick-and-place demos—while keeping the self-balancing chassis intact. To drive everything, I need an internal “brain” (Raspberry Pi, ESP32, or another MCU you’re comfortable with) that can: • run onboard code without any phone connection • store multiple programs in flash so I can swap behaviors on the fly • process a forward-facing camera for navigation and object tracking • handle voice-command triggers and speak back in character using a small speaker For interaction I’m l...

The KnifeBox is an automated dual-blade system that adjusts with high precision the opening between two knives, controlled by Omron NX102-1100 PLC via EtherCAT and EtherNet/IP. Each knife is driven by an Omron 1S servo motor (R88M-1M40030T, 400 W) with R88D-1SN04H-ECT drive and a 10:1 Apex AB060 gearbox. The system includes an HMI (Omron NB/NA) connected over EtherNet/IP for operation, monitoring, and diagnostics. The goal is to achieve and maintain two nominal openings — 400 µm and 700 µm — or a custom value defined by the operator or external PLC. The PLC must continuously calculate the current opening (difference between right and left knife positions), display it on the HMI, and send it in real time via EtherNet/IP to the main line PLC. Safety is critical: any...

This project calls for a skilled welder who can recommend the best process—MIG, TIG, or Arc—once the specific joint design and material are confirmed. I’m still finalising whether the work will involve steel, aluminium, or stainless, and whether the end-goal is a repair, a fresh fabrication, or something decorative, so your guidance on technique, filler metals, and required prep will be valuable. You’ll need to supply your own equipment, demonstrate consistent bead quality, and meet standard safety practices. Clear photos or short clips showing set-up, test passes, and finished welds will serve as acceptance criteria. Please outline the process you would follow, the codes or standards you normally work to, and typical turnaround times.

I already have a working Flex Tool for vanilla Revit that reads a duct-to-grille pick, sizes the flex, and drops in the correct spigot. Since our workflows have moved to Revit Fabrication, I now need that same speed and accuracy inside the fabrication environment. Here is what I expect you to deliver: • Auto-size the flex run from the two picked points on the fabrication duct and the grille connector. • Place the spigot automatically at that location. • If the duct is too flat for the required diameter, select an oval spigot from our existing library and place it instead. • Tie the whole process into the fabrication database so part numbers, materials and sizes come through cleanly and schedules stay correct. • Provide the advanced material and size selec...

I have a gas-liquid separator whose internal geometry needs to be verified before fabrication. The task is a complete CFD study of multiphase flow through the vessel, capturing the interaction between gas and liquid phases. My main concerns are flow distribution across the internals, overall pressure drop, and the resulting phase-separation efficiency, so the model must resolve these three metrics quantitatively. A CAD file of the current layout, design operating conditions, and fluid properties will be supplied at project start. The simulation should be run at the specified throughput, using an appropriate multiphase model (VOF, Euler-Euler, or similar) in Fluent, CFX, OpenFOAM, or another recognised solver, with mesh independence demonstrated. Please include transient behaviour if it ma...

I’ve just received an aftermarket Overland roof rack kit from for my 2017 Subaru Crosstrek and need someone to put it together and bolt it on correctly. Everything that came in the box is here, but I don’t own any of the tools required to do the job, so you’ll need to bring a full set ratchets, torque wrench, Allen keys, sealant, the works. The task is straightforward but must be done cleanly: • Unbox and verify all Overland parts against the packing list. • Assemble the rack on-site, following the manufacturer’s torque specs. • Fit it to the factory mounting points on the Crosstrek without scratching paint or bending the weather-seals. • Double-check alignment and take me through a quick shake-test so we’re both confident everyth...

Our three-month wastewater-treatment-plant build in Jubail City is entering the mechanical installation stage and requires full-time, hands-on supervision. The heaviest concentration of work will be around pumps, the associated piping runs, and the blower train, followed by tanks, DAF units and sludge-handling equipment. Daily duties span progress tracking, quality checks, contractor coordination and interface management across all plant interconnections. Because the blowers and DAF units must tie cleanly into the electrical network, you will be leading the electrical connections and integrations as well—paying particular attention to insulation and protection so we avoid any start-up surprises. I am counting on a Mechanical Engineering graduate with 5–10 years of industr...

I need an engineer-designer who can take my concept for a medical-grade breath-sampling mouthpiece and turn it into a production-ready part. The core requirement is a passive, purely mechanical flow restrictor that caps expiratory flow at roughly 100 mL/s so the downstream analyser always receives a stable, repeatable sample. Material and user experience The body should be 3d printed or injection - mouldable plastic; no mixed elastomers unless you recommend a soft over-mould solely for the lip interface. Above all, the final geometry must feel natural between the lips—comfort outweighs cleaning convenience or extreme durability in this application. Performance specifics • Flow restriction: target 100 mL/s ±10 %, unpowered, with typical adult exhalation pressures. ...
