An Embarassing Failure

Charley

Unless you are prone to working n the shop with your pants down, how could it be an "em bare assing" failure?

You might want to consider turning another ring for the outside and pressing the original top into it? That would lower the centre of gravity and by making the top stouter and heavier overall.

Hello!
A few things to think of when you're making a top.


The lower the center of gravity and the further the mass is from the center will give the top stability and momentum retention.

When you twist the top with your finger you'll notice if you have a larger shank diameter it will not spin as fast as a smaller shank diameter. The shank should be as small as possible to still grip


Eta: The top pictured will spin almost 5 minutes.

Before you modify it, you might try spinning it by winding a string around the knob and pulling. If you get enough rpm's, it should stabilize.
 
There is no such thing as 'failure', they are but 'Learning Experiences'.
 
Top heavy tops will spin ok once the speed is sufficient.
There are some tops that are designed to spin with the fingers but flip to upside down as they slow and keep spinning.
 
Interesting topic. My 8 year old son had taken a keen interest in spinning tops and we have been looking online at videos of tops add potential deliveries by Santa. We found a YouTube video of a top that not only spun for a really long time but actually stopped still upright, at the end of the video a hand eventually comes into view and touches it and then it falls over.
