| M4 "Nylock" Grubscrews....... |

Surely that's OK as long as they're not locked together. Back the lock screw off until the hexagons line up and then push the key in further. Tighten, then pull out to engage only the lock screw. I have no experience of this idea - I'm just going on the description. Russell |

Russell. The problem is, I mustn't tighten the main screw. As it will lock the gib to the slide....... The screws are used to position the gib, in a sliding fit. Tightening the lock screw, just turns the main screw further in. I'll leave it, until/ if there's a problem. Then I'll have a go turning a recess around a new screw, and fitting a little O ring.

I had a similar problem. I removed the slide and relocated the grub screw positions so they cleared the offending object. Added one more screw for a total of four. Plugged the center hole with a shorter screw. But, you may not want to drill through your cross slide. |
| Stilldrillin:
Yes! that would solve the problem Steve. But I prefer to take the "easy" way, if I can......... :thumbup: Frankly, three screws have worked perfectly well for the past 8 years. And the present mod has notched up 2 days, no problem... I wonder if I dreamt about grubscrews, with a longitudinal stiff strip? :scratch: David D |
| BillTodd:
Russell has nailed it:-) Just back the adjuster out a twelfth of a turn berfore locking. One important note: the gibs must be prevented from sliding relative to the adjusting screws else they'll ride up the adjuster points and jam. It is better to have a flat/cylinderical end on the adjusters that fit into shallow pockets rather than the more usual point and counter sink. |
