Here is the only picture I have. There is another thread on how the machine itself was assembled below, but those are old and when I used a stamped metal z that I abandoned.
Here is the base. - this is old - now using x-carve x-axis plates instead of the older style. The key here is to make sure your base is dead square. This base MAKES the maker slide square and solid. Also, a lower center of gravity increases the stability of the x and z axes. I can only mill 1/2" thick material unless I carve a deeper pocket into the base. But - this machine is dedicated to metal. It now has forced air/coolant and shelf liner protective hoodies over the v-wheels.
