Every now and also then us come across homemade roller coasters draft by amateurs and built in their very own backyards. While we appreciate the effort and also creativity that goes into building one, many look poorly made and are that questionable safety. That is until we discovered Paul Gregg, a retirement aerospace engineer that holds 29 US and also foreign patents, 2 special invention awards, and also was Boeing Aerospace engineer of the Year in 1988. Paul supplies his engineering skills to design and also test his backyard roller coasters until he can prove castle are reasonably safe come ride and also operate, i beg your pardon I’m certain his grandchildren love! We recently gained to questioning Paul a few questions around how he provides math, science, and his engineering experience to design and also build backyard roller coasters and why he determined to write a book around it.

Thanks again come Paul for taking the time and sharing his understanding with us. I really enjoyed reading his new book since he included part personalinformation and also stories and I felt choose I was acquiring to know him and his approach to design and also how to design a for sure backyard coaster. You can watch Paul’s backyard coasters ~ above his YouTube Channel and if you want to learn how to develop your own roller coaster you can purchase his new book, Backyard Roller Coaster Research and also Development: Volume I, here: http://backyardrollercoasters.org/

Update: us did a 2nd interview through Paul, click below to read more about track, wheel design, and also steering.
