    Cylinder misalignment question

    Hello, I am building my first engine (4 stroke spark ignition) and one of the questions I have is regarding how much error is accepted in the position between the crankshaft and the cylinder. Theoretically they should be perpendicular, but does anyone know if a slight angle deviation will...

    Would a brass crankshaft work on a model engine?

    Thanks everyone for your input. I am making the webs out of brass and will make the shaft out of steel and will solder it with silver. That should make the process much easier. Thank you again for the ideas

    Would a brass crankshaft work on a model engine?

    Hello, I know that the ideal choice for crankshaft is steel but I have a watchmaker Emco Unimat 3 lathe and it's difficult to machine large steel components. I am working on a small boxer 4 engine and have already made some components (engine block, cylinder sleeves, pistons, etc.) And now...

    Metal casting at home

    Hello Pat J. Thank you for all your messages and links with references. I saw the videos from Kelly Coffield on lost-foam backyard casting. The results are impressive, but I agree that making the patterns is very tedious, and since I don´t have a CNC mill or router, I will not use that method...
