One of the final jobs is creating two gland nuts to seal the cylinder and valve chest.  Stuart supply a section of hex bar for this.  After turning down to the required diameter, I used the drill chuck in the tailstock to keep the die square as I cut the thread.

Removing the die and using it backwards allowed me to get the thread nice and close to the shoulder:

With both ends of the hex bar threaded appropriately, I could then drill and ream for the valve rod – the cylinder gland needs to be larger, but that can be done after parting off:

The finish left after parting off was quite acceptable – it remained to use a small file to round off the sharp edges of the hex bar for a nicer finish:

The part left in the chuck could now have its bore enlarged for the piston rod.  Here’s the parts nearly finished – just some gentle filing to remove any final marks.
