Well it is the method I use on mine with an appropriate Allen key….

the same table is used in the ArcEuro SX1 – Graham Meek in EIM has commented on the somewhat poor gib design and suggests replacing with ones that more nearly fill the gap – I bought a 2nd SX1 to use as a base for some digital control (keeping my current working model available for making various addons) and decided to replace the gibs with somewhat wider brass being more easily obtainable, rather than Meek’s suggested cast iron, the originals being steel (which should work well on against a cast iron bed) – one of the original gibs was actually significantly banana shaped would happily spin round on a surface plate – I’d always had some problems with keeping the gibs on my original in good adjustment – easy movement in centre often resulted in too tight a movement at extreme travel whilst easing here tended to give some play in centre thus I suspect one of the gibs on my original is also banana shaped as Meek comments that only a small adjustment no more than hand tight of the centre screw should be needed to fully lock the gib
