Looking Good!!
Just a few comments.
You are already set up for 3/8 inch lead screws. Why not switch to 3/8 inch 12 turn ACME? You will get a 25% increase in speed and they are more efficient. Speed is always great to have when you need it; (just like a car) you don’t have to use it, or don’t run it fast but it keeps the lead screws from whipping because the RPMs are lower. It is pretty cheap from MSC and they have nuts too for the bearings. You will have to make new anti-backlash nuts though. I was getting burn marks on some cherry when making rosettes until I cranked it up.
I noticed that you have a modification with the side bars running the length of the machine. These would be a great place to add a center support (or more) for the long pipe.
Keep it up,
