Some years ago, I started to build a tool and cutter grinder, mostly with a view to sharpening endmills. I needed to make a rotary table to mill a curved slot, so I set the grinder project aside. I finished the RT, but never got back to the grinder. This is as far as I got. That's an R8 spindle, since I have a full set of R8 collets.
Today, I had a day off so I decided to make the grinder spindle. I figured an MT2 socket would be the most versatile in order to mount whatever I may need to spin as the project grows. I roughed the taper at around 1 1/2*, to be trued up with a tapered reamer.
It took quite a while to ream out the MT2 socket, but it came out quite nice.
I got to try out my new swing-up threading tool to cut the pre-loading thread.
The finished spindle. Next step is the body that the bearings mount in.
