I need to get in the truck and drive to VT and get some lessons in casting 
Sure. But better make it after mud season, the fifth season of the year is upon us -- the thirty days surrounding the day taxes are due, when Vermont is covered with mud!
As for the table, I made a small temporary one, but want to cast a larger permanent version in iron after the weather warms and the land is dry.
For the permanent version, I want to make something similar to the Myford's Super 7 cross slide (preferably the long version) , but altered fit the Craftsman/Atlas lathe saddle's dovetail ways.
I very much like the British cross slide system. With a similar cross slide I could then also easily build lathe accessories to fit -- as described in UK books by Tubal Cain, JA Radford, and others.
What I would need for that are some basic measurements of the Myford cross slide, and then I could draw up the Atlas version to suit.
Mainly I need the length and width of the table, the Tee groove size and locations, and the location and size of the pivot hole for the top slide. If anyon could help with those, I'd be greatly obliged!
As for the smaller temporary table, I was looking through my scrap bin for something over an inch thick to make into a table of about 4"x4" in size. All I found was a slab of 4" diameter round, about 1-1/2" thick that someone had given me. It was some kind of machining mistake, and had 4 tapped holes in it and some shoulders one side, and a big cone shaped depression in the center of the other side. Outside was still raw, and it was stamped 2021-T4, so good stuff!
I cleaned it up, cut off the shoulders to flatten the top, and bored out the depression on the bottom side to fit the circular dovetailed pedestal on the Craftsman cross slide. I haven't finished it yet -- I need to put in the locking screws and pins. Though small and round, it does look to have some advantages, since it is easily rotable. Some tommy bars, indexing marks and a pointer and it could be used as a rotary table, as well as a small boring table. I also just set my vertical slide from the Gingery lathe project on top of the table, and it seems to fit there as well. I'll need to drill and tap new holes for that.
Unfortunately there's not a lot of bearing, and the center post of the cross slide is not the best design for taking heavy loads, so I'll need to be careful. A much better solution will be the larger cast iron Myford style cross slide that I hope to build, since it will bear all the way across the saddle, instead of at one point on the dovetail pedestal.
Anyway here are some photos showing the construction of the Craftsman saddle, and the new small boring/rotary table and the vertical slide setup:
The small table cleaned up and bored. The Sears Craftsman/Atlas 12" cross slide has dovetail ways, and a dovetailed post for accepting the top slide.
The small table mounted in place. It still needs fixing screws and pins.
Trying my smaller lathe's vertical slide to see if it will fit.
