I've designed a 65mm spindle mount to fit a Shapeoko2! I'm using this mount to hold a Chinese water-cooled 65mm AC spindle.

It is an alternate version of the dust-collection foot. This version doesn't restrict air-flow as much, but it does obscure more of the cutting head. I think its better at containing chips and fine dust, but you be the judge! For extra-credit, try adding a strip-brush to make the seal even better!
