Rare is the day when i follow through with pics, but i had the camera and got finished early so... after a beer, i took some pictures of the old girl.
here is the spindle size 1.5 inches and morse taper 4.5View attachment 48014
Here is the same spindle with a 4.5 to 3 reducerView attachment 48015
and here is the collet nose in the spindle with a 5C collet (5/16 iirc) View attachment 48016
So if you ahve the collet closer and nose (and thread protector... forgot to take a pic of that), you can use them with a piece of steel tapered to 60 degrees.
