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...

je suis aussi intéressé Salutations LZ

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...

KAISER swiss made

The original kit was made by Emidio GATTAFONI in 2004. But, Emidio is now very aged. I bought mine from him. JT-modelle make copy of this kit with authorisation of the creator if my informations are right. If JT-modelle have no more kits, I don't know who's follow it now. But the HP is also a...

Best Wishes for 2024, and good luck to all! Now I reamed the center to 9mm. this is for a centering pin, for later. Dismantling the chuck + returning to the lathe to bore the lower part and cut off. Now, I glued the body into an aluminum tube to straighten + ream the upper part. LeZap
