    stepper motor control using arduino

    Hi Folks! This is a complete tutorial/code to build a very interesting and complex electronic indexing head: Snailworks Electronic Index Build Log I have followed it and is fully functional and easy to build. Being on MPCNC forum, one programming skilled, supportive fellow helped me modifying...

    30cc Inline Twin 4-stroke Engine based on Westbury's Wallaby

    Hi Greg, I like very much your build and I appreciate much more your effort in presenting a full tutorial + plans. Though not first on my list - I'm aiming for a more basic design that could be my first 4 stroke IC motor, I consider it a straight forward. I like it, like the presentation style...

    Hello from Brad, Romania

    Thank you very much! I do appreciate HMEM a lot for all it offers to model engine lovers. I have learned a lot from here and much more, I have been part of making true of many personal projects!

    Whippet Westbury style engine.

    This could be my first built engine, and I have set on a Westbury Whippet - like engine. The reason is that it is a 4 stroke (which would be a must for me) and it is a common/proven and forgiving design. It will be down-scaled and stock material built vs original. At least, this is the plan. As...

    Hello from Brad, Romania

    Hi, I've been a member of HMEM for about a year or so, but never presented myself. I'm 53 and I have always enjoyed thermo' engines. For me they are a combination between mechanics and thermodynamics. Thermodynamics are pure physics and mechanics (meaning concept/workshop output) are pure human...

    V-TWIN---MAYBE V-4

    Hi Brian. First I have to say I follow closely this thread and I enjoy both your design solution and the build. Looking at full sized engines ways of dealing with this (I'm speaking of the 3rd piston ring area), how about making radial holes in piston and maybe in the cast iron ring combined...

    5 stroke engine

    Hi, Kerosene flame temperature is about 2400C , steam cycle high temp is slightly above 500C. There were some industrial applications of topping cycles (many retrofit in stationary plants) based on liquid metal (mercury or other) to intermediate the difference between the 2 temperatures. there...

    5 stroke engine

    There are various methods to extract wasted energy from an engine both from gas pressure and thermal gradient. The recovered energy is quite low compared to already existing output. Of course I don't expect big engine manufacturers to go in all directions, considering price increase and engine...

    Why not ductile cast iron?

    Thank you for your answers. I will look for the mentioned thread. The reason is looking for an easy find raw material here, in Romania. Mihai

    5 stroke engine

    Hi gg89220. I very much appreciate your project. I think you are only at the middle of it. There's no doubt that an IC linked with a compressor will work, especially if mechanical chain is reduced to a minimum. Please go further! I know you want to prove yourself something and I'm preety sure we...

    Hello everybody!

    Thank you for your warm welcome! I think everybody needs support -technical and not only - and beginners are the the first in need. Mihai

    Plans for my first build/s

    Thank you for your answer, UpshurEngineWorks - rocketr.net looks very appealing.

    Why not ductile cast iron?

    Why ductile cast iron is not an acceptable alternative for cylinder liner/ piston rings? I know the the grey iron has favourable tribological properties but steel is also used for liners/rings. From my experience ductile iron is in the middle concerning machinability and wear behaviour. It also...

    Plans for my first build/s

    Hi, I am looking for plans/ideea for my first builds. My targets for the moment are rather utilitary engines -though I'm not intending yet to use them in any project. They should be small capacity 4 stroke singles - side valves/ OHV and OHC, also have in mind a boxer twin of same type and maybe...

    Hello everybody!

    Hi, I am from Deva, Hunedoara county, Romania. I have turned to pieces few real size car engines and brought them back to new life. I've read some old-style books about internal combustion engines; clasification, basic thermodynamics and mechanics, design, machining techniques, development...
