Thank you for all of the feedback.
So basically, one can do everything on an 1100 that they can on a 770 but since the 770 has a faster spindle, it can work aluminum much faster hence saving time, right?
It sounds like I will need to pick my endmills carefully and set myself for minimal final finish endmill cleanup passes. I will most likely need to explore the use of ball endmills for my finish passes since the shapes I am working on will be more organic.
I can't afford an expensive ultrasonic sander yet but will look into less expensive alternatives like scotch brite and soft blasting techniques.
I may look into a vibration tumbler to get the mold parts closer. If anyone has a recommendation or link to more info on them, I am all ears.
Thanks again.
Thanks for the link Brad.
Best,
Nathan
