I have, what feels like about .1 of movement in the Y. I've not taken anything apart, that was just holding the table and giviing it a push and a pull.

I think that could be enough, as on a 10 mil rad, the flat is about 4 to 5 mil wide, sounds feasible that that could be what it is, thanks chaps.

Next mission is to find out how it comes apart, haha.
