    Parksy's v4

    Hi rubyfocus, yes still around. Life has been hectic the last year and haven’t been on here as much as I’d like. I’m fairly certain the firing order information is in this thread somewhere. Valve timing wise, both camshafts are made identical, and I’m also sure the specs...

    Longboy's "BEST FRIEND FOUR" model gas engine.

    Looking good longboy. Will be following this build. Oh and you have no idea how much it pleases me that someone is using my idea.:)

    Electrolysis, and cast iron.

    I've plated cast iron with nickel. Can be done.

    Ghosty's "V" Twin

    Drill a hole in the centre of it and loctite a rod in place. Use a trepaning tool to cut a deep and wide enough groove into the side so you can use the lathe chuck to hold it. This is how I make 100mm steel flywheels on the sieg sc3 lathe.

    Panther Pup Help - Won't Run!

    I had issues starting my v4 and it was an electrical issue. I tried running it with glow plugs on nitro fuel and it started right away. If you have the ability to try a glow plug, I highly recommend it.

    Vertical I.C. Rupnow Engine

    Herbie, i would try and run it with a vapour carb for trouble shooting purposes. Doesnt need to be anything fancy, just a glass jar and some tubing. Just to see if you get a different result.

    Ghosty's "V" Twin

    Anything that produces an uneven firing pattern within the 720 degrees is good in my books. Purely from a sound perspective.

    Radial engines

    Thank you all for your responses. I would love to make a radial engine one day and in my mind, the cam ring and gears to drive it would be the hardest part of the project.

    Radial engines

    What sort of bore to stroke ratio do radials generally have? Do they run a flywheel? I assume they run a dry sum system. What are the critical oiling points inside?

    Radial engines

    Thanks guys, I really appreciate this information. Gbritnell, I meant to say four stroke, not four cylinder. I seem to do that a lot...

    Radial engines

    Hi all I was wondering how people go about machining the cam ring in four stroke radial engines. A conventional cam is relatively straight forwards to machine using a mill and rotary table. Can a cam ring be done in a similar fashion? Things I've learnt so far are that a 9cylinder radial has...

    Engine on the Fly

    Excellent work Ghosty. This didn't take much time at all. Was that the first attempt at starting?

    Good Old Aussie Post

    Let me guess, Aust post? They've increased prices, reduced delivery days and the CEO is one of Australia's highest income earners. Terrible.

    Valve seat cutting

    Hi all I wanted to post an update on this as it may (or not) benefit someone. While making the valve cages for the v4 engine, I did try using a 90 degree chamfer to cut the seat. I did this while the valve cage was still chucked on the lathe and not yet parted off. Once the valves were...
