Hi all: me again :-)
I have my new Haas mini mill installed in the old garage now and am happily making big lumps of plastic turn into smaller lumps of plastic quite well :-) A lot of my big lumps of plastic are circular in profile so I quite often (90% of the time) hold them in a standard lathe 3 jaw chuck.
The problem with this method is my chuck is of dubious quality and the faces/points (bits that contact the workpiece) are not perpendicular to the table so if doing two op's part alignment can be dubious. If I had a lathe with a toolpost grinder I could sort this problem out, but I don't. So is there a way of doing something on the mill, without screwing over my fine new Haas investment with loads of grinding dust, that will help me with my alignment problem?
As an aside I had thought about flattening off the top of some soft jaws and making a set of pie jaws to bolt on, or making some soft jaws in the vice for the smaller bits (40mm diameter aka 1.5") . If I were to do this do you cut your soft jaws slightly undersize, if so how under size, or just bang on?
Cheers all
Jools
