so it's easy to add two blocks into each side of the X axis but the problem with the gibs.. (3dshooter80) was right! and I think to go 2" each side without gibs is losing accuracy and possible vibrations.... and I think that is true specially if you do cut next to that area..
for CNC if you are going to replace the lead screw then longer ball screw is required to full the length of the X axis travel..
it's better to increase the Y axis than the X axis since the Y axis is done by just cutting the extra metal in the saddle channel.
and for that main reason I picked G0704 against PM727M I have plan to make supporting metal that can be screwed on the column from top to the bottom and then that metal will go like L and set on flat plate that both the base (saddle ) and the column will set on it and the L will screw on that plate now with this modification you can add 3 phase motor with 2 Hp and you don't have to think even about the tilting or any rigidity problem..
then extending the Y Axis up to 9" at the end will have very ridged 9x18 travel mill!
I was about to call Grizzly and ship my G0704 back and get the Pm727m instead!
I am getting my mill tomorrow!!!
