Next step will be to mount a Kart hydraulic disc brake to slow the flywheel.   The rotating assembly will then be dynamically balanced. I spun the flywheel up to about 4000 rpm and it was relatively smooth in the vertical axis but when decelerating it would vibrate laterally a small amount then go away and re appear at a lower rpm. likely another issue stemming from welding two plates together.


Wow some nice work.  Some great fabrication work there.
I caught a glimpse of your Miller Tig, very nice.


I was wondering if the vibrations could be caused by harmonics since it only seems to happen at certain RPM's.
If so you might have to put a break on it to slow down faster and eliminating the problem.
