turners cube

dan
ther is no need to have a self centering four jaw chuck.i use a small homemade jig,which consists of a piece of 4" dia bar which i mounted four pieces of 3/4" keysteel to form the outside dim of the cube, two adj pieces being threaded for 5/16" shcs.the jig is mountud in conventional 4 jaw,is just a simple matter of loosening 2 screws and indexing to next face.to facilitate cutting free the internal cubes you make 5 steped buttons to fit in the holes of each completed side.ie ,for 3 cubes they need 3 steps of corosponding dia's and depth of counterbore.unfortunatly i live in outback australia and digital cameras arn't common.but i will see what i can do to get some pictures for you.
regards
brad
