  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area.

    Update on the Atkinson compression problem. Yesterday I had some time so pulled the spark plug out and shone a light into the 3/16 hole into the cylinder barrel behind the spark plug cavity. Rotated the engine until the left piston came back on the intake stroke. At the end of it's stroke it...

    Atkinson Differential Engine.

    Oh yes, Probably all of the above over a lot of years. If you want something really different, see if you can find anything on a Hesselman diesel. Not sure if I spelled it right. It was supposed to be the best features of a gasoline and diesel engine all rolled into one. It has had a magneto...

    Atkinson Differential Engine.

He had a 6 cylinder Cat engine in his truck and it was serving him very well. He was pulling the hill out of the boat ramp...

    Atkinson Differential Engine.

    Has anybody here built the Atkinson Differential engine by Vincent R. Gingery and actually got it to run? I built one and it turned out very well. I went through the run in procedure by hooking it up to an electric motor and running it for hours. It seems like it is firing OK but not strong...
