  • 5 Cyl. Radial Engine Video

    George Bulliss and crew were kind enough to post plans of the radial engine I designed in the January 2011 issue of The Home Shop Machinist. If any of you are interested in it, here is a link to the video on Youtube.---Brian Rupnow

    Nice,
    First thing I thought of was a Turkish belly dancer.

    Slight pause for some asinine Tiffiepedia remark.

    Don't know why it was just the first thing that came into my head.

    You are to be commended on the time and work you have put into this to show the end result for other to share - thanks.

        It would be even neeter in slow motion.

            Brings to mind a scene in the '50s movie Operation Petticoat http://en.wikipedia.org/wiki/Operation_Petticoat
            where a broken spring or linkage on the submarine engine or pump was replaced with a woman's elastic girdle, rigged such that it inadvertently provided a humerous and suggestive movement.

                Great job and it runs real nice.

                Is it based off of the "hula hula" design?

                  Not really. The hula-hula design that I seen a video of had stacked connecting rods and offset cylinders. I wanted to design one closer to a true radial engine where all of the cylinders are in line and all the con rods go to a common journal and are all in line instead of being stacked.

                      I am seeing it right that the cylinders wiggle?

                          C'mon Brian, your original "Design" was going to have stacked con rods, you were advised to research "Master conrod"

                          Regards Ian.
                          You might not like what I say,but that doesn't mean I'm wrong.

                            Yes you are Noah. That type of cylinder arrangement is called a "wobbler". There are many great examples of single and twin cylinder wobbler type angines.

                              Yes Ian, and when I did, I wanted to design one with a " master conrod" on it. Not all design in this world springs from an original thought that has never been thought of beforre by someone else. Design is a process of evolution. The few people in this world who had a conpletely original thought are now all living on tropical islands with hot and cold running maids.
