After a lot of time and effort building a welded steel fixed gantry router and then starting to build a granite surface plate mill, I've come to the conclusion that I don't have the time or patience to build and complete a strong/true CNC frame.
The machine's purpose is mostly AL or plastic milling. I looked into a Tormach or Syil X5, but the overall footprints of these machines won't fit into my tiny work area. That and I've already spent thousands on motors, spindles and rails/screws I rolled the dice on this;

I sent the wire transfer 2/12 and received the frame today 4/4 via port to door shipping. I dealt with David from Fullmida who had provided a full .stp model. The frame I rec'd is pretty much dead on to the model except for the headstock. The stp model has a 110mm clamp headstock, but the one I received has a 80mm headstock. I had confirmed this w David before I purchased it and it is fine as I currently have a 80mm Jainken spindle. To get the >80mm headstock was several hundred dollars more and I didnt want to convolute an already convoluted transaction. I do plan on getting a larger spindle to move up to BT30 tooling but the 80mm will be fine for now. Because I had the model I was able to pre order all the linear components to size and it looks like everything fits just right.
My first step will be getting a base together then prepping the frame for kinematics. I have a fairly large steel base from my steel router, but the dimensions are a bit off and the weight of the new frame is about twice that of the router at 600lbs for frame only.
The machined surfaces have a goldish clear lacquer like coating. Anyone have tips on how to treat/prep the machined surfaces?
The other goodies so far;
-2.2kw Jainken ISO 20 spindle, will be upgraded to 3.2kw BT30 Jainken or FM30 cncdepot
-400w Delta AC servo drivers for all axis
-Centroid Acorn controller
