No the X saddle will be just steel like it is now.

The base now have been baked for 26 hours at a max temp of 55 degrees in the end. Now it will be waiting on some measuring devices and epoxy to try to make the steel plates flat so i can mount the rail.
In the mean time im working on the Column design.
Im in contact with some Chinese sellers for a big servo for driving the spindle. currently im doubting what to do my BT30 spindle has a max rpm of 6000 but maybe in the future i will update it to higher rpm.
Now the servo i can buy will be or 8000 rpm or 12000 rpm but it comes with a 390 dollar higher price. On my current mill i also have a 6000 rpm spindle which seems enough but more is always better.
Would it be smart to already buy a high rpm spindle or just stick to an 8000 rpm max and use that money for something else.

I've always tried living by the principal of buying the best of what you can afford at the time because it increases the longevity of you using that item and not having to purchase the same or similar item again.

Having said that my suggestion would be to buy a high rpm spindle.

After doing a great job of the base and you are not having the rail mounting surfaces machine, mounting them on epoxy is not a good idea, all your rail and mounting areas need to be machined
