Well I was thinking about making some kind of a column support plate to reduce the flexing/vibration of the column of my Micromark SX2 mill, but the more I think about it, I like the idea of the extra inch of Y and two extra inches of Z travel that I would get with LMS' solid column conversion kit.

But before I try to cough up the money, I'm wondering, has this mod been shown in practice to make a big difference in terms of flexing and vibration?
