Hi Steve,
No I did not do it at the end... The casting of the column was twisted... Could not get the precision I needed.
If yours comes from Warco, It will probably be better. Just don't get it from Amadeal, these are horible.

At that time it was pretty difficult to find any kits, but these days the X2 CNC kits are available in a lot of places. So you should not have too much trouble. :-)
