Final Proposal Presentation Team F1 Climbing Hold Resurfacer: Abdullah Alenezi Mohammad Almutairi Kyle Connelly Drew Shumway Dylan Simon

Project Description Purpose: Develop system to restore texture on used/worn out climbing holds Client: John Doskicz of Flagstaff Climbing Center Importance: Texture will extend life of rock climbing holds. Solution will save climbing gyms money. It will reduce waste to landfill. Holds are often made from toxic materials. Figure 1: Flagstaff Climbing Center [1] 2 Dylan

Initial CAD Model Figure 2: Design 3

Customer Requirements 1) Save money 2) Climbing holds will gain usable texture while resembling original hold 3) Can be applied to majority of hold collection 4) Can be stored reasonably 5) Can recolor 4

Engineering Requirements 1) 80% original texture (surface roughness 5.5x10-5in ) 2) Cost of operation (< $3.00/hold) 3) Size of device (< 6 ft longest length) 4) Durability of machine (>500 holds before maintenance) 5) Color (visual color scale) 5

Final Design Components - Ultrasonic Cleaner Non- invasive Can run batches of holds Set on timer = low human input Reasonable Price Figure 3: Ultrasonic Cleaner [2] 6

Final Design Components - Ultrasonic Cleaner Before After Figure 4: Ultrasonic Cleaner Testing 7

Final Design Components - Resin Dip Figure 5: Textured Dip Concept Testing 8

Final Design Components - Resin Dip No texture has been finalized. Each potential material would include polymer resin and sand. Potential solutions: Epoxy Acrylic Nylon Polyurethane Food Grade Urethane Figure 6: Castable Resin [3] 9

Final Design Components - Mixer Original idea was an egg mixer like the one pictured below or a motorized one. Motor ● Disposable mixing rods ● Disposable protective sheet ● 10 Figure 7: Mixer [5]

Final Design Components - Color Color can easily be added to resin during mixing. Figure 8: Color Dye 11

Next Steps Price comparison for resins Further ultrasonic cleaner tests Figure 9: Coefficient of Friction Tester [6] Friction testing Surface roughness testing Figure 10: Surface Roughness Image [7] 12 Drew

Schedule - Currently on Schedule Figure 11: Gantt Chart 13

Budget Now $2,000 available Allows for larger scale system $200 testing budget $500 reserve budget $1300 for parts and materials Figure 12: Bill of materials 14
