so after doing a little research i am redoing my x2.
some of the mods are c-channel column bracing, hydraulic cement filling or epoxy filling the column, treadmill motor and controller upgrade, belt drive, spindle bearing replacement with SKF bearings. Once all that is done i am going to make new brass gibs and then lap the surfaces.
so the spindle motor has been harvested along with choke and controller.
Now i am bending up a 20 gage sheet metal box and top to mount all the electronics stuff. I am housing a 3 way swith to go from pc to manual spindle control like hoss, the mc-60 controller, the motor choke the c-10 board, the c-23 board, the c-6 board, stock e-stop a forwar and reverse 3 way switch, and 4.7 POT.
I already have the column and spindle a part for changing the bearings to the needed ones.
got the column brace material. I have 2 options:
1. a 4x4x1/4 square tube that goes all the way up the column. I no longer have the control box on the back so i can brace all the way up.
2. I have a section of 5x1/2 c-channel that will go all the way up the back.
which would be the better choice?
I also figured out the belt drive base late that i will use to mount the 2 hp motor without interfering with the z axis ballscrew and mount. I will use the belt drive base plate to also adjust the x axis tram tool devised by john sheperd(

So this is what i am working on now.
