Modifications Needed

These pictures detail the small modifications that need to be made to the Super 7 lathe before the CNC kit can be added.

Modification to Cross-Slide and Saddle ends

 

The Cross-Slide needs to have two holes drilled and tapped M5 in the end so that the protective end plate/homing switch mount can be attached. (A jig will be provided to enable positioning of the holes). You can also see that the Ball Screw rear nut mount requires two holes to be drilled and tapped M5. (Again, a jig will be provided for drilling alignment).
Note: Not all saddles have the 1/2″ hole ready drilled! If this is the case then you will need to drill this hole accurately to match the alignment of the hole in the front of the saddle.

ML7 & Super 7 Saddles

The above picture shows the difference between an ML7 and a Super 7 Saddle .  The saddle on the left is an ML7, the screw driver is pointing to one of the extra holes that are in a Super 7 Saddle. Notice also the width difference of the cross-slide bearing surface.
