This variant of the Lambda top is machined from a single piece of solid brass bar stock. This consumes 4x the amount of brass compared to the two-piece tops, but it also delivers a more perfect spin. Any machinist will tell you that the most accurate part is the one machined to completion without removing it from the machine.

This also means I went from 2 manual machining operations on the two-piece top, to 5 manual operations on the solid top. Does that make the Lambda Solid an even more unpleasant slog of boring, repetitive manual labor? Yep. Is it worth it? Totally.

The Lambda was the first spinning top to feature an instrument ruby contact point and many imitators followed. Hundreds of hours have been dedicated to design and testing to bring you the world's most high performance top. Accept no substitutes.
