Horizontal mill cutters and spacers

I tried several times to upload a few pictures, but couldn't get it to work. "Upload Failed" was all I got.

The end of the arbor has what looks like 1A stamped into it. There is also a stub arbor. Not yet sure what to do with that.

Thanks for all the responses.

Hardinge sold two size arbors I am aware of-1" and 7/8". 1" seems to have been the standard that most machines came with. 7/8" don't show up much and I have only one. You have a factory Hardinge arbor. None came with keyways, at least none that I have seen and I have owned many of these machines. Your spacers are not Hardinge though. Hardinge spacers do not have keyways. Obviously this is not a problem as friction is all that prevents a cutter from spinning. Make sure the nut is tight before you start cutting. I don't believe I have spun a cutter (yet) on my Hardinge mills. Enjoy. They are great machines, in my opinion. Gary R.
 
Gary,

Thanks for the reply. I'm looking forward to learning a lot on the machine.

Do you have any comments or information about the stub arbor?

Thanks,
Mike

I don't recognize this stub arbor as orginal Hardinge equipment. It should still be a useful tool holder for saws and some mill cutters but the work will need to be close to the spindle with this short reach. Hardinge did have some stub arbor equipment. One style similar to your piece came in 3 sizes if I remember correctly-3/8, 1/2 and 5/8 dia. Each came with spacers like the larger arbors. The arbor sticks out of the 5c collet mount maybe 2 inches. I have two of the three sizes and could post pictures of them if there is interest. I also have Hardinge documentation that shows an arbor similar to a fly cutter. This would be useful say to cut a gear using a lathe tool if you didn't have a gear cutter which would mount on the regular arbor. There are one or two Hardinge groups at Yahoo groups that would be worth checking out. I don't recall but some of this info might be there. Enjoy the learning journey. Gary
 
Thanks for the info.

I would be interested in seeing the pictures.

Thanks,
Mike
 
I had these very same questions with my Hardinge, thank you all for the information!
 
The Atlas I had used a #2 Morse taper. My #4 Burke used a #9 B&S taper,which was considerably larger,and not as tapered IIRC.

Not quite on topic but does anybody have a source of Arbors, 1" would be good, with a B&S #9 taper on them?

Jeff Beck has them for the Atlas mill but they do not have the correct taper. I once asked him about supplying them but I guess the market is too small.

The B&S mill arbors are rare. I have a mill that uses a B&S #10 and I have not found a source for a B&S #10 anything. I am toying with setting up and making my own.

A buddy of mine just got a new-old Burke mill with a B&S #9 spindle taper that came with a somewhat battered 1 inch arbor. The need for a new replacement and possible different sizes for the small slitter saws came up. My thoughts on the subject was to get a set of B&S #9 collets or at least the largest one available and make whatever size arbor shaft needed and just size the driving end to fit the largest collect available. Jeff Beck offers the B&S #9 collet set shown at http://www.tools4cheap.net/proddetail.php?prod=bs9. The largest collet in that set is 3/4 inch.
