Yea! And for the same amount of effort and difficulty I can recommend a couple as well!

- build your own kit car. Maybe start with something easy like a Ford GT with a V8 from a donor Mustang!

- build a kit airplane! Make it a jet for a little bit of extra challenge!

- make a rotary engine from scratch! Make your own materials!

- now a figure 8 propeller piston engine!

- create your own chip fab facility!
