Hi folks, Got myself a new milling vice, a Vertex K5, and the thing is baked in solidified shipping grease which doesn't dissolve with WD40 or brake cleaner. Got most of it removed but I can't get to the underside of the moveable jaw in order to clean it up. There is a locking collar in front of the handle which takes the thrust when you wind the vice out. It's a standard steel collar with two grub screws securing it, which the manual describes as 'tapered pins' (I presume they are just grub screws with a point on the end, which fits into a dimple). The problem is they take a 2.5mm hex key and they won't budge. Tried oil, heat, various types of hex keys, nothing. Luckily the heads on them haven't shredded but they definitely won't move. Any tips on what to try here? Usually when I encounter this problem it's on a motorbike and I get the air gun out, but I'm worried about buggering the hexagon up. Should I just drill em out? Rich |

Hi Rich, As no one else has replied to your question let me offer this; If they are taper pins they need to be driven out with a pin punch and a hammer, not an Allen key. If they are indeed taper one end will be smaller than the other, make sure you hit the small end! If an Allen key will fit , they could be "roll pins" , which are cylindrical, in which case they will be parallel and will come out either way. If they are really Allen grubs screws, use a key, if they round off you are no worse off as you will have to drill them out anyway. Ned |

If it is grease causing the issue, try a little bit of heat? |

I have the same make of vice but the 4 in version..I would try the tap approach with a pin punch ...Youl'l feel any opposition to movement by the solid feeling when you hit the punch with the hammer...If they are roll pins and hollow, can you get something down the hollow? |
