control cable questions

Having to reject the last nicropress
on the rudder, two strands were cut when the nircopress was cut off with a
drmel tool.

The question is whether we can reinstall a nicropress in the original
position and then add one an 1/8" further?? or,

Make splice two lengths of control cable with double nicropresses?? or,


Is there any reason why a turnbuckle couldn't be used ouitside the fuselage
at the rudder??

Thanks
