I changed my bearings and have not properly tightened the castle nut on the lathe spindle. I have been advised it needs 30 ftlbs.

I need a socket that will fit the nut and fit my torque wrench.

I looked at the internet and the result came up blank.

The castle nut on my machine is about 52mm in outside diameter and across the narrow parts of the slots it is 46mm.

I found a 38mm socket has the metal in it to do the job.



Here it is offered up to the spindle nuts.



I turned the inside and out to clean it up and open the inside to 46.1mm to fit into the nut slots.



Next, the “teeth” can be machined on the mill.
