  • Tramming in a mill/drill

    I remember seeing on here a while back ways to tram in a mini mill/drill. I have the generic HF variety (technically Homier) with the "big nut" style tilting head adjustment. I could tram that part in OK, but this post (that I can't find through search) was talking about IIRC 6 degrees of freedom that need tramming in. I figure if I'm going to take it apart to replace the broken gear inside, that I might as well get it nice and trammed in. I don't really know the ins and outs of tramming as I have never done it before (new mill user) so if anyone remembers where that post is or wants to help out that would be awesome. Thanks
    You never learn anything by doing it right.

    My notes on squaring and tramming in a mill or vise are here:

    Sounds like you're interested in squaring, which will involve shimming the column until it is square to the table. Some folks would also take the opportunity to install a pin so the trammed head stays trammed, but that's a function of whether you think you'll want to use the head tilt much.
