Une autre méthode pour usiner les jougs. Basé sur des roulements à billes. LZ

Quelques photos de l'avancement. LZ

je suis occupé à tourner dans les différentes parties du moteur LZ

Hi Richard, yes, one piece. LZ

Salut Dave, quelles sont les nouvelles ? LZ

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

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

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.

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...

Two misfired valves! The first difficulty is that the bores are different, by a few hundredths but still. Then the bore has a taper of 0.02mm by 50mm, this is unacceptable but real! Machining valves with -0.01mm clearance and taper is not a big problem. The first one, I missed because I was...

bonne idée !, je vais suivre ta suggestion, mais en terminant avec une fraise en bout LeZap

Désolé, je suis un peu en retard dans mes publications. Il s'agit du roulement de bielle fini avec l'écrou de blocage. Montage vierge UN Centrage avec le centrifugeur Deckel Dispositif de graissage sans graisseur et vis provisoire Dernière difficulté avant le montage, les quatre...

and the finished connecting rod.

I left the parts for which I did not have machining solutions until last. But after a few sleepless nights thinking about it, the ideas come. Below, the master connecting rod. It’s a good 3km long! For square drilling, apart from a file, I don't see it. Unless a kind soul would have a square...

The valve is now finished. Last part is the throttle valve wheel. LZ

The video is not exactly a "manual lathe" and he works on brass. Stainless Steel 304 it's other things! Cast iron was just a peace of cake. There is my method. LZ

The centering went well, I was within 0,02-0,03 mm The first picture is the machining of the valve seat. 60° In the end, everything fits together without forcing or hard points. All that remains is the wheel to be machined. L.Z.

I'm not particularly happy with the thread, but they do the job. The drill bit is 1.6. But, it's made from Stainless steel 304, and not very easy for machining LZ

Now, machining two machine jig in M19 x 70. One of the caps is cut from the same stainless steel. But threading in this material is really painful and the finish.....boff... To have as perfect an alignment as possible, here is the machining sequence I will follow. First machine parts 160 and 162...
