[QUOTE="J E Custom, post: 1365098, member: 2736"] I made my self a 4 screw Spider with brass inserts in the screws for the tail of the spindle and dial the muzzle in the same way I dial the shank end of the barrel but it does take two rods at the same time and two dial indicators. Once I get the barrel dialed in on both ends it never comes out of the lathe until all threading and chambering is done. the spider seems to hold the barrel very well and stays in alignment. While I'm set up I also check the od of the barrel, and if it is not true to the bore, I re-contour between centers so that everything is symmetrical and true to the bore. Some say this is not necessary, but I don't mind the extra time in order to end up with everything as near as perfect as "I" Am capable of. Just the way I do it J E CUSTOM [/QUOTE]
