You sure are just moving right along on the Corliss. It will not be long and it will be running.

Waiting for ordered tools, I start again.
The first two images are tests to validate the direction of rotation in self-tightening, speed and depth.
First, lathe machining, at a dimension + 0.03.
Then finish with a flat file + 800 grit paper, to the exact dimension with "0" clearance. This is to finish with fine lapping paste afterwards.
Then without disassembling the part, I transfer the chuck to the divider of my “13”
First open with a 20mm, 1mm thick disc cutter. As a reminder, I need 1.58 finished by 7 deep.
Then use a 1.5 end mill. Advance of 11mm/T and 2000rpm (maximum I can have)
At this moment, I have already cut 2mm deep and I assure you that I am watching like milk on the fire!!
Fortunately I only need two valves with an opening of 1/16"

Looking really good! Good plan!

Hello, after a break due to some domestics duties, I'm back.
The four valves are now finished. Two was wrong machined....
Now, all the parts are finished and I will start slowly the assembly/ fit of all the parts.

J'ai trouvé sur le net quelques informations sur le montage de ce moteur Corliss
Je profite de traduire en français

Ôn l'arrière du cylindre, je place 4 petits disques en aluminium
C'est pour ajuster le timing d'ouverture et de fermeture

Did you make those bonnets one piece or two pieces. I cannot tell.
