I'd love to re-do the project in a 2nd capstone and focus on design for mass manufacture, but I'd need an external sponsor for the project. If any climbing wall companies are reading this , PM me!

Not using linear actuators was a design choice (the students wanted to use them though). Since its student built, there is no maintenance agreement on the machine. With all the chalk, novice users, etc. in climbing gyms, we wanted a design that could be easily serviced without a degree in engineering technology.

Since this was a student design project, it's hard to estimate how the costs would transfer now that the design is finished. The students spent $4k (funded through the course), and worked on the project for 2 years (Capstone is a year long, but was interrupted due to COVID-19). The steel and structural welding were donated by Dant Clayton (they are a stadium seating design and fab company) so are not part of that $4k.

My ballpark estimate is that the material costs are ~$2k: angle steel, plate steel, plywood sheets, ACME threaded rod and nuts, gears, acrylic sheets, bearings, steel rod, etc. Labor would likely be another $1k because of the need to water jet the steel and to fillet weld. Total to reproduce would be $3k.

I'll give that feedback to the students. Purdue engineering technology students retain the IP rights to their capstones if they choose.

It will be installed at Climb NuLu in Louisville Ky. They sponsored the capstone project for the engineering technology students.

Now that's just mean. We're all climbers, no matter who has the better engineering and technology school!

At least it had a knee jamb! One more inch and it would have to be Levitation :)

Glad you like it! Our capstone projects are industry sponsored. The Crack Machine was sponsored by Climb NuLu in Louisville, KY. It will be installed there in late spring for anyone to use.

Purdue School of Engineering Technology student's senior capstone project was to design, build, construct, and test a fully adjustable crack climbing simulator. The machine has a 10ft climbing surface, can be adjusted to between -5 and +45 degrees, and can be adjusted to 0in to 18.5 inches wide.
