[QUOTE="MagnumManiac, post: 2061571, member: 10755"] It all depends on how concentric your centreline is from chuck to tail stock. I have an old lathe which has .0018” eccentric in the chuck...someone prior to me purchasing it drove the bit holder into the chuck, no amount of shimming would fix it, only made it worse. I worked for a gunsmith whose lathe was .008” out...he wouldn’t replace it. If those cheap lathes can keep concentricity then it is viable. You can live with a few thou out, but it’s better if there is none. Fixtures made on a lathe that are out will be out too, unless you true them prior to making the finished product. Cheers. P. S. My turned solid bullets are CNC made. The price is very reasonable for a solid. The aluminium versions are 3 times the cost and outside my budget or needs. [/QUOTE]
