Project Description Issue: Loss of texture over time Client: John Doskicz of Flagstaff Climbing Figure 1: Flagstaff Climbing Center [1] Center Clean Retexture Recolor Goal: Retexture indoor climbing holds to save money over time Kyle 2

Requirements Customer Requirements Engineering Requirements Save money 80% original texture (surface roughness 5.5x10-5in ) Climbing holds will gain usable texture while resembling original hold Cost of operation (< $3.00/hold) Can be applied to majority of hold Size of device (< 6 ft longest length) collection Durability of machine (>500 holds before Can be stored reasonably maintenance) Can recolor Color (visual color scale) Kyle 3

Original Design Resin based texture Figure 2: Original Design Kyle 4

Design Changes Table was not necessary Texture is now concrete based Dipsticks are not manufactured (all materials can be purchased) Ultrasonic cleaner is bought rather than built Included a drying rack Dylan 5

50% Hardware Review Final texture developed Adhesives, aggregates, colors Ultrasonic cleaner, cleaner solution test Figure 3: Sample Textures Dylan 6

Ultrasonic Cleaner Vinegar + Water mixture is the most effective Time to clean is 30 to 60 min Before After Dylan 7 Figure 4: Ultrasonic Cleaner test

The Mix What’s in it Concrete fortifier ● Concrete for patching ● Copper slag aggregate ● (optional) Dye (optional) ● Water (optional) ● Figure 5: Mixture Materials Dylan 8

The first of its kind The holds pictured to the right were the first holds to be given to Flagstaff Climbing to be put on the wall. Seen below is the second attempt at a hold to be put on the wall. Figure 6: Retextured Holds Dylan 9

95% Completion - Hardware Review 2 Construct dip sticks ● Construct drying rack ● Remove texture from resurfaced holds ● Test resurfaced holds in ultrasonic cleaner ● Drew 10

Dipstick Figure 7: CAD and finished Dipping Rods Drew 11

Dipstick Petroleum jelly prevents texture adhesion to bolt or hose. The rubber hose expanded as expected to fill the bolt hole. Figure 8: Testing Dipping rods Drew 12

Drying Rack Drew 13 Figure 9: CAD and Physical Drying Rack

Continuous Improvement The texture is not perfect. We are working on making it more durable. We tested vinyl concrete patch ready mix yesterday. Finishing touches on drying rack (back stopper) Abdullah 14 Figure 10: Retextured Hold
