    That's cute. I hadn't thought about making a radial engine out of the oscilating engine.

      Very nice work Jim,pretty impressive indeed.What kind of pressure and rpm's are we looking at?Oh and of course where did you obtain the plans for this engine.
      After seeing it run at that speed I would personaly be a little scared to see it throw a rod and ruin all that good work,but it looks as if she's built for it.Once again beautiful little engine excellent work.

            Thanks.It is fun to run.It is running on 40 lbs.I will check and see how many rpms it turns someday.I have ran it faster but figured I will keep it together to sit on my desk in 1 piece.
            I got the plans from an artical from smitty on this board.Dont remember the magazine.I sent it back to him.

              Very nice engine and good video too. Thanks for sharing. I'm a little envious of the monarch 10EE in the background. I'd love to have one here at home. Great lathes. What year is that one and will it cut metric also? Thank your kid for us for making the video viewable.

                The hula-hula engine may be found in the Village Press book "Two Shop Masters".

                Best,

                PS Looks like an awesome project, BTW!

                  Wow...that was a little scary. I too am surprised it diddn't jump off the table with all that Hula going on.

                    japcas.Thanks. The monarch is a 43.No metric but can if I get the gears to do so.Nice machine.
                    It runs very smooth really.I may get the tac on it and see the rpm.I am kinda courious to see anyways.

                        Fantastic little whirly-gig you got there. Must be nice to finish a project, mine all seem to get set aside for something like work.

                        Also like the EE. Had 2 at the last place of employment. They ran so smoooooth. Fairly tough except for that vac-tube power supply. If something in there went south, dig out the wallet.

                          Real nice engine. I enjoyed watching the video. What do you do for lubrication on those. Is it lubed from the compressed air? JRouche

                            Hi JRouche. I squirt a little oil in the inlet and a drop on the crank and wristpins when I start it if it sits a good while.

                              That's very cool. I've seen articles on those, but somehow I never imagined them running so fast. Nice work there.
