Side Valve i.c. engine from Bar stock

Brian Rupnow:
Hooray for my side!!! Just as I was about to go bonkers from terminal boredom, I got a call ten minutes ago for some design engineering work starting tomorrow. I have been thinking about using my new engine to run a lighting plant, using an old bicycle generator, the kind with the friction wheel that ran off the front or rear tire. Dearie me!!!---Time has moved on in the last 55 years since I had a bicycle. I went into 3 bike shops and Canadian tire asking about generators for bicycles, and they all looked at me as if I had two heads. Apparently now, if you want a light on your bicycle, you use batteries and LED's. I see many of these generators (also called dynamos) on ebay but I don't totally trust buying used electrical things from people I don't know in places I have never been to. I will pursue this a bit more though, because I would like to have my new engine power something.---Brian

 Hi Brian,

As you have found out LEDs have revolutionised bike lighting but there are still those who use dynamos. The tyre driven dynamo seems to have disappeared in favour of hub dynamos. I guess the hub type are designed to run at too slow a speed to drive from your engine without a wheel size pulley.

How about just using a permanent magnet motor as a generator.

Phil.

Brian Rupnow:
A very kind gentleman from Michigan who built my Muley style Sawmill and exhibits it at shows around USA has just "volunteered" me a bicycle generator. It will be sent here by snail mail (I assume) and then we will go about building a "lighting plant" for my newest engine to run.---Brian

Back when I tinkered with motorcycles. A pal fitted a bicycle hub dynamo, onto the crankshaft of his trails bike. To provide, "bobby dodger" lighting. (ie. no battery)......

It worked!  :thumbup:
