Norman it looks much better with the mounting lugs. Cheers David |

This vice is nearing completion. This morning I clamped a piece of round bar in it and was pleased to see that the jaws are parallel and it clamps evenly. But, I did learn some useful lessons today also. I wouldn't class myself as inexperienced but most of my engineering work has been with steel, cast iron and aluminium. This morning I had to machine the bronze nut for the leadscrew on my lathe. After a couple of dig-ins using my usual tool I thought that I would grind a new one with no top rake, well, it's chalk and cheese! After that I backed off the point of a drill and it went through with no grabbing. I have always been too lazy to grind separate tools, all I can say is, "what an idiot I am!" The second lesson was not to forget to lock the slides on the milling machine if I want to prevent the cutter from digging in. All in all a couple of useful lessons, I knew about it but had just been in too much of a hurry. |

Sounds like you're coming along, Norman. Can't wait to see the finished vise at work! :thumbup: :beer: |

Taaraaah! It is complete! I have just finished assembling it and am delighted at how smoothly it operates and firmly it clamps. I fitted a roller thrust bearing on the screw which must help with the amount of force needed to clamp it. The capacity of the vice is 100 x 75 x 25mm, I designed it to be 100 x 100 x 25 but the plain section on the screw prevents it from opening further. Next time I plan to make any equipment I should ensure that I have all the parts before casting any metal. All in all it's been a great project and not too time consuming. |

Excellent stuff Norman - glad it's finished and working. Now . . . what's the next project using the milling machine and vice :clap: |
