I learned about the cascading effect a malfunctioning brake lever can have on an electric bike. A frustrating lesson but a diagnostic bit of knowledge I will never forget. Especially after spending hours replacing parts that were fine.

I also learned (painfully) that eye protection isn’t a bad idea to have when servicing front suspension forks for mountain bikes. 10w oil or potentially isopropyl alcohol is no fun to get in your eyes….

Put together a bunk bed. My wife thought our granddaughters, who stay with us frequently, would enjoy them, so we pulled the queen bed out of the upstairs guest bedroom and I assembled a rather well made bunk bed with a full bed bottom and a twin bed top bunk. My gripe was the universal pictures-only assembly instructions, but it went ok and I agree that the girls will have a fun time with them.

Today I learned that the auto-leveling function on our the large 3D printer at work doesn't work well... and I learned to level it manually.

I also learned that I need practice on that -- clearly, I didn't get it right the first time.
