I guess along with reasoning, reading isn't your strong suit.


You know, you'd have a lot more fun if you weren't spring-loaded in the
****ed-off position.


John:

I'm curious -- what did you calculate as the side force on the bearing
-- worst case (edge load of 100lb. -- c.o.g. at platform level -- point
mass -- 150 rpm -- 24" disk -- assuming no vibration due to imbalance
i.e. simplest case).

You seem to be a mech. eng. my specialty is elsewhere -- so not sure I
remember all the stuff I should take into account especially once I
looked at a bit of vibration all bets seemed to be off :-) . (I had to
grab one of my mech eng. books to remind myself of the factors... at
least you can see electrons unlike this mechanical stuff. LOL)

I ask because my quick calculations gave me a higher figure than the
rating of the hub suggested. Not sure there is any safety factor there,
not even sure that the hub suggested is within "required" spec.

Thanks for the thoughts -- even if you don't reply... :-))
