Top 1811 - Brass, Copper and Stainless Steel
This one-of-a-kind top is brass over copper with a stainless steel stem tipped with a 1/8" silicon nitride bearing. Hand machined and aged!. Spun once and stopped at 7:40. Unfortunately this one looks better than it spins, and has a pretty good wobble to it!
