Awesome, glad the shaft worked out for you and no apparent CV issues.
That's correct and if it turns 4.5 or 4.8 times you would know it has 4.56 or 4.77 gearing respectively.
My only problem with this is, how the heck can I tell the difference between 4.5 revolutions and 4.8?? it seems like such a miniscule amount.. will it be apparently obvious, or will I need to use some type of measuring device?
