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.

Thanks.  Really like the Miller Aerowave, kinda an oddball machine. Inverter/transformer machine.

I ordered the disc brake set, see how it spins with the brake disc installed and figure out if it needs further balance work.  Dynamic maybe?

Could be harmonics with the long shafts?  Need to cut em down to size
