Thanks John, forgot about this little problem. I got sidetracked with the newest edition to the CNC family.

Ptfe? I'm only familiar with the plumbers tape, can you get it as solid as well then? Any one with a surface grinder that could Knock me up a new gib strip? (not you John I know your not well,)

Before I get too ahead of myself I also need to check headstock and tail stock alignment and carriage alignment, Ive seen various methods for each element but is there an order to which they should be checked and which is the best method given that I have completely striped and rebuilt it, Any pointers would be good (the bed was leveled with a precision level, not sure of the spec but moved at lot even when a rizzla paper was put underneath)
