No the 6K is a much larger and heftier collet. It will take through stock up to 5/8” while the 3C is limited to ½”

The 3C has a body diameter of 0.650” and a length of 2-11/16

The 6K had a diameter of 0.840 and a length of 3-1/8.

 

Remember the bore in the 10K spindle is bigger than the bore in the 9” Workshop 0.860 against 0.7656.

With that, the 6K is just a MT3 with the slot for the pin. Is that right a right conclusion.

Nelson;

The adapter is used with 3C collets. It does have a pin which engages a slot on the shaft on the 3c collet, preventing the collet from spinning. 

The adapter is held in place by the (almost) 3-MT taper on the spindle ID. 

The (so called) nose protector is used to extract the adapter. 

When using 6K collets the adapter is not used, the extractor is not needed. 

There is a pin on the threads of the 10K spindle which engages a slot on the taper of the 6K collet. Using the extractor/ nose protector hides the pin making collet engagement more complicated.

I'm not a pro at this but I believe the adapter is there to prevent damage to the spindle in event one turns. The adapter has a slot that engages with the pin and will not rotate. But the spindle has a morse taper #3.

That is my take on it.

no, that is not right because its the outer bevel that engages with the pin.

Re: 10K Spindle

Jim B. <btdtrf@...>
 

Always good to check.

Some years I purchased, on eBay, a small collet mounted chuck. The ad stated it was for a SB 9” lathe. I (mentally) read 3C. (The ad never stated 3C.) I wanted the chuck for the index head on my Burke mill which uses 3C collets and purchased it.

When I got it I found it was not 3C. It was a (similar but very different) Rivett 3NS. Apparently the seller had a complete set of Rivett collets which had been adapted to the 9” Workshop and to him the chuck was standard.

 

I (eventually) did make a 3C back for it.

All 10K lathes are that way. They take a 6K collet without an adapter.

They will still take 3C collets with adapters.

Re: 10K Spindle

Ray De Jong
 

Yes, in fact 10K spindles are all that way. Be aware though of the need to use 6K collets and if you want to use 3C collets it will require an adapter which an easy shop made item and a nice little project. I have a 9" and a 10K and made adapters so the great variety of collets I have can be used in both lathes
Have fun

Hi garretsonmike,
 
I did my spindle quite a while back.  I have a 14.5 and I do believe I got the bearing and thrust washers from Mc Master.  I did a quick look at some paperwork and found some numbers,  5909K43 cage assembly and 2  5909K56  .032 thick thrust washers.  They are all for 2" shaft diameter and 2.750 OD.  I do think I made a bushing to fit the shaft from some pvc pipe so as to stay centered.  But I would pull the end cover and look to make sure that is the size.  They are not that expensive, 9 or 10 dollars for both when I got mine, but if they don't fit then you have them hanging around for some other project to be used for.

Re: #2 MT and 5C collet

Lew
 

Attached is a photo of the Hardinge adapter.  If you can lay your hands on one, I believe there would be no need to Loctite anything together.  You may not need to use the driving collar on the TM mill. The need for the driving collar is determined by the workpiece material, the depth and width and cut and the diameter of tooling you would be using (i.e. the torque on tool).  Once you have the adapter in place, you can add a drawbar  for the MT2 tooling.  The MT2 drawbar will ride concentric to the stock 5C drawbar on your TM mill.   

While I do have both the MT3- and the MT2-to-5C adapters, I don't have photos of them at hand.  The attached photo was taken  from Frank Ford's excellent website, Frets.com.

I'd like to obtain a 5C to MT adapter to convert a horizontal mill arbor
for use in a Hardinge UM. Put some of the best lock tite on the taper
and a short bolt through the back end of the 5C into the MT's drawbar
hole and it wouldn't be moving.

The 5C part would need to extend out a bit in order to cut a keyway to
fit a drive collar.

I have one TM/UM arbor that is likely shop made since it lacks the drive
collar. One of those round tuits I need to do to put one on.
