My next mini project with my shapeoko 2, what do you think my chances are of machining 6mm aluminium with stock spindle?

i would think you can do it if you use cutting fluid and have a small step down.

Yeh my thoughts exactly, 4, 2 or 1 flute end mill?

hmm… i dunno. i tend to use whatever i have. i think all might work… not sure what would be best.
