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.

Initial CAD Model

3 Figure 2: Design

Customer Requirements

1) Save money 2) Climbing holds will gain usable texture while resembling

• riginal 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)

Final Design Components - Ultrasonic Cleaner

Non- invasive Can run batches of holds Set on timer = low human input Reasonable Price

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

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.
