A human-powered cutter that uses a bicycle-style pedal drive to spin a cutting mechanism—ideal for off-grid workshops and educational demos on power transmission. Pedaling turns a flywheel via chain/belt; a step-up ratio brings the spindle to cutting speed. Two safe build options are provided:

1. Bandsaw variant (recommended): Pedals drive upper wheel; continuous band blade makes safer, controlled cuts.

2. Circular-saw variant (prototype): Pedals drive a guarded arbor with small-diameter blade for light cross-cuts only.

Important: Education prototype only. Use for softwood/thin sections. Always fit guards, a brake, and an emergency stop. For circular blades, operate two-person (one pedaling, one feeding) or use a flywheel brake + foot-stop so the operator can stop spin instantly.

Parts Used:

1. edal Drive Module: Crankset, pedals, bottom bracket, main chainring
2. Transmission: Roller chain and/or V-belt with selectable sprockets/pulleys (ratio tuning)
3. Freewheel & Safety Clutch: Prevents kickback to pedals; allows over-run
4. Flywheel (3–8 kg): Smooths torque, stabilizes speed
5. Cutting Module (choose one):

• 1. 1. Bandsaw: Two wheels (Ø 250–350 mm), tires, band blade (6–10 TPI), tracking & tensioners

     2. Circular Saw: Arbor/spindle, 160–185 mm blade, riving knife, full upper/lower guards

  2. Table & Fences: Flat worktable with rip fence, miter slot/guide, push stick

  3. Frame: Rigid MS frame, pedestal for table, vibration pads

  4. Braking: Foot-actuated friction brake on flywheel (mandatory)

  5. Dust Management: Shroud + outlet for manual dust bag or shop-vac (optional)

  6. Instrumentation (optional): Tachometer (RPM), simple load indicator

  7. Guards & PPE: Chain/belt guards, blade guards, safety shields
