Wow! Like so many impossible records that were eventually broken, the 1 hour spin is not as impressive any more!  >:D
Congratulations master!

I guess you couldn't decide which camera view was best and you left both  ;D

No ta0, the two cameras are for the 3d-view, cross eyed!

Yes, true. With a brass flywheel and the shroud, three years ago, I reached 1h 10m 31s, so I knew that with a lead flywheel and the same set up it should spin even longer. With tops like these, 1 hour spins are an easy target.

The Sony RX10, (at the left), is my best camera, but it has a defect, it shuts down automatically after 30 minutes video recording, so usually I use a second, cheaper camera, (an old Canon), for to have also a continuous video recording of the full spin, without interruptions. 
If I want to submit the record attempt to RecordSetter, I send them the lower quality video recording without interruptions.
I use the best quality video recording of the other camera for to make a short video for YouTube.

In this case it happened that the video of the best camera was not so good because a bit out of focus. So I decided to include both the video recordings in the same frame for to shrink them and make the out of focus less evident.

This is the full spin video.  The timing starts at 10:30, I spent really much time twirling the top.

Great effort to spin it at over 2,900 RPM!

PS: The auto-range function of the tachometer that switches from RPMs to tenths of RPM when it goes below 1000 RPM confused me at the beginning.

I was at the fourth attempt and at that point my hand was a bit tired. Normally it takes me about 4 minutes to reach 2900 RPM with this top.
