David. I've already tried to work that idea. But, the head is then rather short........ Thanks for the double screw idea Chaps! :clap: Just had a quick fumble, and finished with a working assembly! With 2mm protrusion.... Some more fine tuning, of my screw shortening technique will see it sorted! :thumbup: Thanks All...... For the ideas. :bow: :bow: David D |

ND Industries makes a product called Vibra-Tite. It comes in two forms: solvent evaporation and bake-on. The solvent evaporation version is a goo you paint on the threads and allow to dry for 30 minutes or more. The bake-on variety is painted on, allowed to sit for at least 2 hours, and then baked at 250°F (225°C) until the part is uniformly heated, and then allowed to sit for at least 8 hours before use. It acts like a Nylok insert. The bake-on version survives operational temperatures of 400°F (200°C) quite nicely. You do need to thoroughly degrease the threads before applying. This is my preferred thread locker when a screw needs to be repositionable or retorqueable. Enco, MSC, and Fastenal all have access to it (but it is rarely stocked due to distribution restrictions required by Henkel/Loctite -- a product line I go out of my way to avoid). |

Thanks Lew. I made an M4 chucking sleeve, and finished up with two screws Total, 11mm oal...... Then realised, they couldn't be locked together, as the inner screw can't be tightened against the gib strip. :doh: Any road! Screwed in place. New lock screw installed........ Works well! Thanks Chaps...... :thumbup: David D |

--- Quote ---Then realised, they couldn't be locked together, as the inner screw can't be tightened against the gib strip --- End quote --- that's why hardinge's locking screw has a through hole - try shortening the lock screw until the key will pass through ~3mm |

I follow you Bill...... But, both hexagons are the same a/f, at 2mm. Unless I'm missing something! :scratch: David D |
