Hi Ian,
I've just this morning placed an order with Arceuro for an X2 mill for conversion having just sold one of my lathes to make some space in the workshop and pay for the mill. To keep the costs low I intend to start with the original leadscrews and replace the nuts with homemade anti-backlash acetal nuts. For the Z-axis I intend to do something similar to Hoss here.
