OK, after laying awake trying to figure out why this does not run as nicely as it looks I might have figured something.. That solenoid is an AC device? If so it is quite different in operating principle to a regular DC solenoid. The AC solenoid operates on the same principle as a split phase AC motor so you should probably ignore my earlier comment about giving it a vigorous DC kick. However that still does not explain why it does not work. John |

Al ,,,,,,,,,, Still a great thread whatever the out come :clap: :clap: :clap: :clap: i am sure you will get that cat skinned :med: Rob :thumbup: |

If that is a typical solenoid, the switch should close at or shortly after bottom dead center then open at or shortly before top dead center. Does your switch open or close when the cams push against the button? Chuck |

Has it been tried with only one of the collar-ramps engaging switch? Looks too cool to quit now! Regards, Jamie --- End quote --- Al. I'm with Jamie on this one...... At the final crank rotation....... The solenoid "squarks" at both ends of the stroke....... Or, am I missing something....... :scratch: What a crackin' build. :clap: :clap: Please don't abandon at this point....... :palm: David D |

I dont have a whole lot of experience building motors yet (planing on fixing that once i get a couple of other projects out of the way) but do have abit more than the usual electric/electronic knowhow. an ac solenoid will only work in one direction (usually pull) reversing a dc curentthrough it wont change that. try using a small spring for one direction (I would start with push)and electric excitation for the other(pull). the idea of using capacitors to more grunt is a good one but would need to be fairly big.
