Home-Gym Squat Stand CAD Modeling

CAD BRIEF · NT Lite Stand 2340 | Darwin Sheetmetal · millimetres only
FREELANCER CAD REQUEST
Bolt-together squat stand + 610 mm spotter arms
Model a compact home-gym squat stand with pull-up bar, J-cups and a pair of 610 mm safety arms. Look and function like a Rogue SML-2 / SAML-24, but use Australian steel and millimetres so Darwin Sheetmetal can laser-cut and weld it. No Rogue names or logos on the model or drawings. Project name: NT Lite Stand 2340.
AI draft — you decide the fit-up. This brief was generated with AI from product photos and public specs. Some numbers may conflict with each other or with the pictures. The draftsperson is expected to resolve that. Priorities, in order: (1) every bolt and pin hole lines up so the stand can be assembled without site drilling; (2) J-cups and spotter arms pin onto the uprights at every Westside height without binding; (3) the stand sits flat and the pull-up bar is square; (4) stay on the Australian sections and millimetre sizes below. If a photo inch-mark fights a millimetre in the table, use the millimetre and note the change.

1. What to model
• Two 75 × 75 × 3.0 SHS uprights on a bolt-together U / T base (75 × 50 × 3.0 RHS).
• Single 25NB pull-up bar across the top (Ø33.7 pipe). Pair of open J-cups. Pair of 610 mm spotter arms.
• Westside-style holes on the uprights. All hardware Ø16 mm / M16.
Fig. 1 — Form target (ignore branding and inch arrows).

Fig. 2 — Layout: J-cups on the uprights. Envelope 2,343 × 1,245 × 1,219 mm (from 92″ / 49″ / 48″).

Photos may still show 3×3″, 5/8″, 92″. Do not model those. Use the table.
3. Parts in plain language
Uprights — 4-way Ø16 holes so cups and arms pin from the inside. Number every 100 mm on one face.
Base — two side runners + rear cross member. 5 or 8 mm foot plates with 4× Ø14 floor-anchor holes each side. 5 mm triangle gussets. Uprights bolt on with M16 through laser holes.
Pull-up bar — one 25NB pipe (Ø33.7 × 2.6 Light CHS). Spans the posts, pins in the top hole pair, cannot walk out. Not a fat/skinny pair unless the draftsperson prefers it; 25NB is the call.
J-cups — pair. Open J toward the lifter, wrap on the inside of the upright, pin through a Westside hole. Not a closed hook.

Fig. 3 — J-cup shape.
Spotter arms — pair. 75 × 75 beam, sandwich plate on the upright, hitch-pin under the arm, UHMW on top, welded end stop. Must not rotate when loaded.

Fig. 4 — Arm look. Stamp SARA not ROGUE if any lettering is modelled.
4. How Darwin will cut it
• Laser everything. No drilled holes unless marked tap-drill.
• Plate DXF in mm, 1:1, layer CUT. Tube as STEP / pierce points.
• 3–4 mm fillets typical. Hardware M16 and Ø16 hitch pins only.
• Drawings in millimetres only. No dual inch dimensions.
5. Hand over
• Native CAD (SolidWorks preferred, Fusion OK) + STEP of the assembly and every part.
• DXF for every plate. PDF workshop drawings + ballooned BOM.
• One exploded view and one A3 iso for the fabricator quote.
• Send a skeleton screenshot for approval before detailing welds.
