Rather than bore out a solid lump of steel for the cylinder liner I started with a piece of tube.  Not visible in the photo but I had to remove the tailstock to clear the boring bar and was close to max capacity on bed length.  Used the dividing head to cut the steam passage slots and final photo shows it in position in the cylinder block.

Good progress Simon.  Is the sleeve a push fit or is it glued?

Thanks Vince.  The drawings call for a very light press fit but I've chickened out of that so it will be glued  ;)

The drawings show a very plain cylinder end cover but the real engine has a webbed end cover so decided to try and mimic that.  Milled the webs out and profiled their outer edge in the lathe - plan is to bore out the centre of the end cover and then bond in the webs.

Thanks Jim.  Machined up the main bulk of the end cover with a taper at the bottom of the bore to mate with the taper on the webbed infill piece - amazingly they match quite well so bonded in the webbed piece so I can clean it up when I finish the flange to final thickness.

Pretty pleased with how it turned out even if it does look like a sink plug hole!

Sure looks good Simon, well done. 
I envisaged the centre of the web standing proud by a mm or so and the "fins" angling down to the rim, don't know why.  :shrug:

Thanks guys.  Jim - I know what you mean and the McDivitt Corliss has this feature;

But from the picture below of the engine in the Grand Rapids museum the ribs are if anything sub flush so that was what I was aiming for.

I see what you mean and if we all liked the same things it would be a dull old world so we each do what pleases us. 
And it looks less like a plug hole, although that didn't occur to me until you said it, when it is all painted the same colour.
Whatever, it's a nice detail which will add to the model and well worth the effort.  :ThumbsUp:

Jeff - may add those little jacking screws at some point.

Went to town on the opposite end cylinder cover too trying to match the real engine but this time just did it conventionally milling the pockets into the cast iron.  Took ages using a 3mm cutter taking care to avoid any Lu Lu's.
