Measure or confirm: Gear ratios Tooth profiles Shaft diameters Bearing interfaces Synchroniser assemblies Clearances & tolerances Material specifications (if known) Produce a fully dimensioned 3D CAD model of the OEM gear set and shafts. 2. Dog Engagement Conversion Redesign the gear set to use dog rings and dog engagement hubs. Replace synchro assemblies with dog‑style engagement. Maintain or adjust gear ratios (to be discussed). Ensure compatibility with OEM casing, shafts, bearings, and lubrication system unless otherwise recommended. Provide engineering justification for: Dog tooth count Engagement window geometry Material selection Heat treatment Surface finishing Expected torque capacity 3. Manufacturing Drawings (Critical Deliverable) Provide complete, unambiguous drawings for every component, including: Input shaft Output shaft All gears Dog rings Engagement hubs Selector forks (if redesign required) Spacers, thrust washers, circlips Any modified housings or covers Each drawing must include: Fully dimensioned orthographic views GD&T tolerances Surface finish requirements Material specifications Heat treatment specifications Hardness requirements Machining notes Assembly notes Exploded diagrams where needed 4. Final Deliverables Full 3D CAD model (STEP + native format) Full 2D manufacturing drawing pack (PDF + DXF) Bill of Materials Tolerance stack‑up analysis Assembly instructions Optional: FEA on critical components (quote separately) Required Experience Applicants must demonstrate: Prior work on dog boxes, sequential gearboxes, or motorsport transmissions Strong background in gear design (involute profiles, dog engagement geometry, etc.) Ability to produce manufacturing‑ready drawings Proficiency in CAD (SolidWorks, Inventor, CATIA, or similar) Understanding of heat treatment, case hardening, and high‑strength alloy steels Please include examples of previous gearbox or motorsport drivetrain work in your proposal.

Hi there, I’ve reviewed your Dog Box Conversion project. With proven experience in motorsport transmissions, gear design (dog engagement geometry, tolerances, heat treatment), and producing production-ready drawings, I will deliver a complete CAD model and manufacturing pack tailored to your M66 internals. Approach: 1) Capture gearbox specs (ratios, tooth profiles, shaft diameters, bearing interfaces, synchroniser removal) and produce a fully dimensioned 3D model. 2) Redesign for dog engagement (dog rings/hubs), justify tooth counts, engagement window geometry, heat treatment and materials. 3) Provide complete manufacturing drawings for all parts (GD&T, surface finishes, materials, heat treatment, machining notes, assembly instructions, exploded views). 4) Deliver: STEP + native CAD, PDF + DXF drawings, BOM, tolerance stack‑up; optional FEA on critical parts. Deliverables are compatible with OEM casing, lubrication, and seals, with a clear rationale for any deviations. Questions for you: - Do you have the OEM specs or measured data for the current internals? - Are you aiming to maintain the existing gear ratios or optimize for durability and shift feel? - Any constraints from the casing, lubrication routing, or heat treatment capabilities? - Would you like FEA included in this scope or as a separate quote? What are the exact target gear ratios and torque range for the dog‑box redesign, and are there any OEM constraints we must preserve? Best regards,

Hello I have direct experience in motorsport gearbox and drivetrain design, including dog-engagement conversions, gear train modeling, shaft design, and production-ready manufacturing drawings with GD&T, materials, and heat-treatment specs. I’ve delivered CNC-ready drawing packs for high-load transmissions where durability, engagement geometry, and tolerance control are critical. My approach is to first fully reverse-model the OEM gear set, then engineer the dog engagement system around torque capacity, engagement speed, lubrication, and OEM casing compatibility, finishing with unambiguous manufacturing documentation. Key technical points I’ll address: • Dog tooth geometry, count, and engagement windows • Material selection, case hardening, and surface finish • Tolerance stack-up and assembly clearances Thanks
