In this video we repair a fantastic Fell All Way level. This spectacular instrument was invented and patented by William Fell around 1940. It is unique in that it can simultaneously evaluate two axes. It is ideal for machine leveling and setting up precision equipment. This level can resolve below .0005/ft or roughly 8 arc seconds of angle. Check out, patents.google.com/patent/US2316777A/en
We disassemble the level and open the vial for refilling and bring this unique instrument back to life.
