Introduction and History

• The East coast and the Chesapeake involve a heavy
  fishing market
• Currently in the market, there is no machine
  designed for production of crab clips
• Crab clips are originally made by hand with the
  assistance of a design plate with placed screws,
  etc.
• Economists predict there will be a decrease in
  cost, which will re-spark an interest in crabbing
• This response will put our machine to good use
• Will eliminate cost of buying crab bait clips and
  save time

Objectives

• To create a semi-automatic machine that is
  capable of creating multiple Jimmy clips
• -Jimmy clips are used in the crab industry as
  holders for bait in crab traps
• Combination of skills in design of Jimmy clip
  maker
• Incorporate assembly drawings into manufacturing
• Maintain within project budget of 1,000
• Supply/Order parts necessary for machine to
  function

4
Initial Planning

• Brainstorming
• Original Designs
• Initial component pricing
• Material Selection (Ex steel, zinc, aluminum, or
  stainless steel)
• Overall design
• Finalized assembly drawing

5
Design

• Jimmi Clip Design
• Overall Functionality
• General Machine Design
• Using Inventor to Aid in Drawing Parts
• Part Clearances and Motions

Operation Instructions (Shortened Version)

• Procedure
• a. The operating instructions for this project
  are simple and easy
• 1) Press Button 1 (hook is made)
• 2) Raise handle (90º bend is made)
• 3) Press Button 2 (540º coil is made) Solenoid
  pushes pin off machine
• b. Emergency Kill Switch is a silver toggle
  button that is located at the bottom right side
  of machine

Safety and Precautions ! ! !

• Be aware of objects in motion
• Make sure all wiring is properly grounded
• Only operator should be near pin maker while in
  operation
• Always wear safety glasses, goggles and/or
  protective gear

Recommendations

• 1. Parts should be welded first, then machined
• 2. Components not in motion should be
  supported/reinforced
• Rack Plate
• 3. Limit switches should be better mounted
• 4. Certain dimensions should be measured more
  accurately
• Rack Plate
• Short Actuator Support Plate
• 5. Parts should not be ordered until plans are
  well thought out and parts are machined
• 6. Decisions considering project should be
  unanimous
• 7. Complex contour parts should be done on CNC
  machine
• Coiling Wheel
• Support Legs
• T-Slide
• Rack Support Plate
• Actuator 1.625 Plate
• 8. Common thread types throughout project
• ¼-20
• ¾-10 LH
• 9. Tolerances should have been established before
  project began

Budget

• Total Budget was 1,000
• Amount spent was 864.59
• Under budget by 135.41
