Taiolstock_Offset | = | part_len * Taper_Per_Foot |
On my South Bend, I should be able to obtain 0.200" offset on the tail stock. That is about a 0.5" swing from side to side. So, to cut a taper for my tailstock (a #2 taper), my taper-per-foot is 0.5994. If I use a 4.5" piece of steel for this, I will get (4.5 * 0.5994) / 24, which comes out to 0.11238750 ". That means, I can use a 3/4" piece of round bar about 5" long to cut a taper with about 1.5" extra inches to put a flange on. I only have to offset the tail stock about an eighth of an inch to do it, and I'd have the spindle for the die holder to run on.
