complete overhaul of x2
« on: September 27, 2010, 01:45:15 PM »
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( http://www.homemodelenginemachinist.com/index.php?topic=6007.0 post#11).  I am also putting tramming adjusters on the side of the spindle carriage as found on cnccookbook( http://www.cnccookbook.com/CCMillTramAdj.html http://www.cnczone.com/forums/showpost.php?p=745618&postcount=324. )

So this is what i am working on now.
