The front doors are tilted back therefore the drawer slides used to connect them at the top are under additional stress when the drawer slides are extended (door closed position)   You can see the stock slides are shot when compared to the new Accuride ones.  After creating new holes and mounts the new slides have been attached to the doors. 

The doors are hung but sag when they are closed because of the tilt factor.  I am not real happy about this as the doors should open and close effortlessly.  So, I plan too attached a truck / rail system at the top connecting the large opening to remove this sag and allow the drawer slides to perform with out the tilt stress.  This will allow the top of the doors to be connected at 2 points instead of just 1.   At least the is the current plan….

Control Panel Structure

I took some old steel shelves and cut them into the control panel sides for the basic box structure.  Drilled holes and sanded them for the spot welds and got the basic box constructed.  The front side where the CNC cut bezel is now drilled and tapped into place, then made a quick access panel for the back side so the wiring for buttons can be installed with ease.  I should have the screen mounted in the next couple of days as the internal mount fabrication is almost complete.

Thanks Marty...  A large portion of the junk in my shop is from industrial trash

Finished up the internal mounts and gusset for the 17in LCD screen and added a simple keyboard tray with support gussets.   The top and bottom of the enclosor also have covers so the basic box is complete.  Once the paint is on it will look like new.

Next I need to get it connected to the mill with a swivel and provide a place for the cables to run.

The Spindle Housing Cover was cracked and is very wobbly.  Since I am in sheet metal mode, we whipped out a quick plate to keep the damage from getting worse and to minimize the wobble.

Finally got the front doors hung and adjusted.  Didnt need the top rail after all.  Just needed more TLC and shims..

Using 2 chunks of angle, we welded up the the cable tray.  Then with square tube, the control mounting arm was fabricated and welded to cable tray.

I put an offset in the control arm for cable to route from the box into the tray.

A piano hinge was welded to the mounting arm and wedge was made for the bottom.  With the cable tray and wedge installed, the mounting arm is ROCK solid.  The control panel has 1/4 20 screws to connect to the mounting arm.  This way the control panel can be removed as one part.  The same for the cable tray and arm, one assembly that is bolted to the CNC.

Now the control panel is mounted and swings nicely, just need to finish the swivel cable tray from the control to the main tray.
