[QUOTE="nksmfamjp, post: 1935383, member: 1951"] Interesting, I was surprised to hear him basically slightly oversized the receiver threads with the idea that torquing to the face, lug, shank will hold it square. The other camp says you have to single point cut them... Which do you do? Has anybody done much testing both ways? For the bolt, he clamps the bolt running true to about 0.001”, the cuts the aluminum holding jig, then reclamps to the jig and spider. The jig seems to add variation, But can the spider be dialed to remove that variation? The other method being to hold the bolt with a truing jig and adjust until the bolt body has minimal runout. Seem similar methods. Is one better, more direct? [/QUOTE]
