Thanks Bill... --- Quote from: BillTodd on December 11, 2011, 06:40:28 AM ---Doug's Museum of Retrotech my provide inspiration : --- End quote --- Everytime I look there I am tempted by the Brennon gyrocars!. --- Quote ---Your separate combustion chamber is a good idea, but may only work well if you have some kind of fuel injection. A long stroke 2-stoke will probably require some kind of deflector piston if cylinder ported, but I wonder if it is possible to arrange to have the scavenge blast shot up from the centre of the piston? (your fixed con-rod may help) --- End quote --- I had been pondering self a operating poppet valve(s) in the piston crown.. :coffee: --- Quote ---Or.How about something wild ? Have the combustion chamber at the 'bottom' and use the con-rod to control the scavenge (making the cylinder uni-flow) making the engine pull on the con-rod :) --- End quote --- Thats worth a thought, doing it that way around would make it easy to mount the carb. on the end of the engine.. |

Fergus, BC, I have often admired such machines and noticed two very lightweight mopeds for sale just last week but my friends dragged me away before I could fall victim to their faded, but still very obvious, charms. I want to make something that will be totally different and as quirky as possible. |

I'm over 81 but I recall my father who claimed that he had a motor cycle which had no kick start. It had running boards and an exhaust valve lifter. One simply ran along with the valve lifted- until it fired- and then one was too exhausted to jump on. Again, I had a Silent Lee Velocette complete with hand start-- and a rather watercooled radiator to keep legs warm in winter. Mind you, I was watching the Antiques Road Show and some one had a set of paintings of Noddy and his little car. Seat made only 27 of them from the original Fiat 500 or 600 Little Mouse. I found one in deplorable state in Menorca but the price was daft. I was going to buy a pair of ordinary ones and bring them back in a furniture van to the UK, do it up body wise, get the wicker work done by the local blind school and give it to the kids who at 14 were already driving- on the back of the beach! And then the bloke ' Welshed' and finally it is buried in a football field. Oddly, next door to a cave belonging to a deaf Arab who abducted a local Spanish virgin( her story) and he was finally tracked down- in the snow- on a Spanish Island- and he jumped off a 300 foot cliff- later to be followed by a Brit-- on one of your bloody daft bikes. Well, it is a true story- or mine is. Go buy your confounded bike-- and have fun! Cheers F O'M |

Fergus, I aint buying nothing! If I cant find the bits I need at the landfill the job will not go ahead! :D I wondered about those old bikes, how did one ever manage in town if you had to stop at an intersection etc, maybe like those cyclists I saw in Beijing? They came up to the corner and if the lights were against them they all went into a sort of 'holding pattern', a dozen or so cyclists riding in a tight circle until the lights changed. One of my first projects was a Noddy car, cold molded ply on a Triumph Herald chassis, it went rather well with the light body but the proportions were all wrong with the motor making the front too heavy. So I rebuilt it... P1010033 by aardvark_akubra, on Flickr Incidently, when I was building this one I took the old 'Noddy' body to the landfill. Two guys in a pick up truck saw me heading that way and did a u-turn obviously hoping to 'score' a vintage car and being careful not to get too close in case I might try to sell it to them. I had cruel pleasure heaving it off the trailer and sending it tumbling down the mountain of household rubbish and used disposable nappies. I hung around just long enough to see them jump out of their truck and start scrambling down..... :med: |

Great story! Proves that there is initiative left. Oddly, I watched British TV with a symphony orchestra playing '1812' at the Royal Albert Hall but with instruments made from scrapyards. And they got a standing ovation!!!! Keep at it, the 'Empire' depends on you! Cheers Fergus---- and that's a daft name. Comes from a mythical ghost - a long grey man that lives on a Scottish mountain. Near a whisky trail and Loch Ness, I have to confess! |
