John, I think this conversation is on topic as it relates to mating the Taig Z to the CNCBridges base, but if you want to create a new thread let me know.
That said, just wanted to make sure you understand that the milling head attaches tot he column via a dovetail slide. And that Taig makes extensions for the lathe that will work. Of course if you already have the tools to make your own, then never mind
Also, I'll send you a PM to get the pricing Nick gave ou, or you can post it. His prices reflect Taig's - 10%, but I'm not sure what all sub parts make up the whole assembly.
Thanks,
Jay
