After doing some initial aluminum cutting and also running into some size limitations with the stock Shapeoko2, I decided I need to upgrade the machine to make it both a) larger and b) stiffer.
Inventable's X-Carve has a number of parts that are bolt-on upgrades that are compatible with the Shapeoko 2. The first I purchased was the improved DC Spindle mount. This provided a much-improved interface between the DC spindle and the Z-axis slide- both improved rigidity and alignment. It's machined from a single aluminum extrusion and black anodized.

Installation of the upgrades was pretty straightforward. The entire Shapeoko2 X axis needs to be disassembled. The wheels and stepper motor can be attached to the X-Carriage. Then, the X-carriage extrusion is slid over the X-axis Makerslide extrusions.

I also took the opportunity to expand the stock build surface using new makerslide and some 8020 extrusions I purchased from an industrial salvage place.

I used the stock 500mm x 500mm wasteboard, then added a new wasteboard I cut from 1/2" MDF. I did buy a set of 5mm threaded inserts to add hold downs to the new section.
