Top 1703 - Brass and copper
This one of a kind top is brass with a copper stem tipped with a 1/8" silicon nitride bearing. The stem has been hollowed out to lower the center of gravity. Hand machined and polished, this is a great little spinner that spins smooth and should be in the 6-8 minute range for an average spinner like me.
1" diameter.
Weighs 58 grams.
