I haven't seen too many examples of this configuration and I was just wondering why?
Is it too complex, not overkill?
On first thougth, it seems to have alot going for it, besides the cost of extra components.
The spindle mount would be very simple with the minimum of overhang and one could have a longer Z axis to allow for higher jobs.

Have I missed something obvious?....

I hope to be building a T Slot Router one day and I would like to know if this is a viable option.
Your thoughts?
