Thanks @Pete. my concern is that the jib is about 1/2" short of start of the adusting screw with the rear screw fully home, so the adjusters are doing nothing. Looks like I need a jib about 3/4" longer.You can shim the non-working side of the gib. A shim of a few thou thickness will bring it back within working range.
You might also want to scrape the working face to stop it sticking and allow some oil pockets to retain lubricant.

Aye it it does, knew there was wear when I bought it, it was worse than I expected, lucky I have not had to make anything very long on it.**Language** me that's got some wear
There is some damage to the face of it, I will stick a post on the M300 forum to check what length the jib should be.That doesn't make sense. Unless the narrow end has snapped off. Does it look like it was cut or broken?

Though I Think the issue is, with the jib against the fully screwed in rear adjuster screw, there is this gap to the front screw:
Well it's only the cross slide which won't affect to much. A nice project to scrape in.Aye it it does, knew there was wear when I bought it, it was worse than I expected, lucky I have not had to make anything very long on it.

Thats the problem, think I would need to make a washer with a lug where the gib strip sits and a pin on the lug to push against the jib.I think the depth of the pocket in the cross slide will be the limiting factor there.
nice idea, will see how hard it is.Until you find a new gib, is it possible to put it in the 4 jaw and drill and tap both ends, then loctite socket head screws into both ends to elongate the gib and get the adjuster screws to have something to work against?
Standard gib is 390mm, replacement oversize is approx. 440mm.There is some damage to the face of it, I will stick a post on the M300 forum to check what length the jib should be.
Mine is 325mm long! So 65mm short on narrow end.Standard gib is 390mm, replacement oversize is approx. 440mm.
