1323 forum posts 1431 photos | Just made 12 M8 fine stainless hex-head bolts for a mates bike - made the bolt from round bar and machined the hex on the rotary table using the 3-jaw chuck. Centred the chuck with a piece of 8mm bar in the chuck, and then did the bolts one after another - no faffing with 4 jaws ( or 2 at least..) each bolt time...The chuck centres as quickly as one would centre a bar in a 4-jaw. The same backplate /centering ring also takes the 5C collet chuck, so the centering ring mechanism works a treat. Joe |

The way I get it concentric is place my morse taper test bar in the hole in the RT
then place the chuck over it
clamp the jaws onto the test bar then bolt the chuck down
undo jaws and knock the test bar out
