Test notes/comments:

starting temp approx 27C

ramp up :20rpm, 400kN, 40 rpm, 60 rpm, 80 rpm

first capture at stationary bearing

Test conditions after 5 min 45

rainy day (no sun)

extremely steep temperature gradient after hitting 100rpm

laptop charger was in same extension

cables repositioned around 3hr 15-16 approx because a vibration in cable point where resting on rig was noticed

4hr 36 approx some bounce noticed in rig, video taken from strongest side but still present on other side

clank around 5hr 05min, could be from outside

c12 = 05:30:00 - 05:30:00 d last capture is of stationary bearing


unloading
reduced to 20 rpm 
load removed - as load came off rpm jumped up before reducing again dor some reason
