Echesak - somehow I couldn't see your post when writing mine ,I think I have not refreshed the page for some time. That seems to be exactly the same idea :)

Wow! I didn't expect so many replies. Thanks to everyone! I should have specified what I'm looking for in the first post. What I need is something similar to a Wankel rotor case - it has to be very smooth on the inside just like in a Wankel engine. Thats because I would like to try to build an...

Thanks for your input :) Thats not what i mean, an endmill will leave a round hole, just where it makes contact with the surface will be elyptical . I'm after something like the 'cylinder case' in a Wankel engine but instead of the 'double-bubble' shape I want it to be elyptical. By the way -...

Hello! How would you attempt to mill an elyptical 'hole' without a CNC? I know the 'pantograph' or 'copy' method. I'm interested in milling this shape using a conventional mill. Also the question is not limited to a milling machine. Maybe there is a different way? Any ideas are welcome...

Today I've made another reed valve flap (petal?), this time bigger, covering the intake hole better then the previous one. Checked it with my mouth blowing and sucking air through the intake. I think it seals better - but thats just the 'mouth comparison'. It tries to run. I can clearly hear the...

Amazing work! I hope its not too much to ask but would you like to share some details about the turbo? Are you planning on connecting it to the intake? I know its probably not going to make any boost at this scale but i still fancy the idea. Keep it up! Cheers!

Ok here is a quick video. Sorry for poor quality. I got it to run for 10 seconds and it dies. I want to try a hotter glow plug. If anyone has any ideas what might be wrong, please let me know. Cheers!

Well I'm back with some good news. It pops! I was so excited i took only two pictures :) Yesterday i was cleaning up my shop and i stumbled upon this little engine which i kinda forgot about. It was a quick decision - no more cleaning, let's finish building the engine ;) I couldn't find the...

No updates because I'm stuck on the glow plug thread. A hand or machine tap is almost impossible to buy in Poland or is very expensive and my lathe only does metric threads.... What to do?

hmm, that was my first post soo.. Hello everyone! My name is Igor, I'm 28 (1988) and I come from Poland. Thank You for the kind words, it means a lot to me. Ok, so i bought a wireless keybord as it was cheaper then repairing the existing one (laptop). @Niels : Unfortunately i don't have a...

12mm bore, 12mm stroke, ci piston, steel liner with 3 intake passages, intake timing governed by a rotor plate. sorry for poor description but i'm using on-screen keybord... more to come. cheers from Poland!!!
