Well that's the first mistake but fortunately it can be rectified easily - the 8mm hole in the last part should be an 11mm hole (8mm is the pump piston diameter, doh!). So, set it back up on the lathe drill to 10mm (my nearest drill) then some nice boring to size. When boring goes well it's great!
The circle about halfway 'twixt hole and edge is where I marked out for the fixing holes.
Once that was finished it was time to start on the gland. The first attempt was ok but the spigot was a rather loose fit in the hole so I turned the piece around and did it again. Second attempt came out much better, here it is with the two diameters turned to size then mated with the steel part.
The part was reversed and the 8mm hole reamed (yeah, the right size in this part :P). Just needs some facing down the the right thickness but I didn't have time to complete that so it's still in the chuck and no picture to show.
