Vintage Thing No.36 - the Honda CJ250T

Tempted? It was during a rather ribald discussion with some of my motor cycling friends that the question arose -- what is the motorcycling equivalent of an Austin Allegro? My Austin Allegro is a particularly nice example but that doesn't stop them taking the piss out of it. I know that it is not one of the world's greatest cars and some people voted these chubby little cars the worst ones of all time but I like to point out that much of the Allegro's vital organs are shared with the Mini, which, at about the same time, was voted the greatest car of all time. It seems odd to me that two cars with the same engine, gearbox and the clutch from the same manufacturer, and with suspension systems that follow the same damperless and space saving concept, could be both the best and the worst between them. But, as we say in Cornwall, "There it is and there you are." And as some deeply philosophical type might also say, "Less is more." After a great deal of...

Nothing but hot air - Stirling engines

Image
I found this chap and his demonstration models of Stirling engines in the model tent at the Boconnoc Steam Fair. I'm afraid I forgot to ask him his name but I had a long chat with him about the Stirling engine and the principles involved. I'd heard of Stirling engines many years ago but had discounted from my sphere of interest because they didn't have any automotive application. Stirling engines operate simply on temperature differentials. Low friction materials have given a new lease of life to this very old concept, named after Rev Dr Robert Stirling who patented the idea in 1816. Boyle's Law states that as the temperature of a gas in a sealed container increases so does its pressure and the Stirling engine exploits this principle by have a heat source and a heat sink, such as air fins. When gas is allowed in contact with the cold and heat alternately, it can move a piston, displacer or diaphragm, which in turn can drive a crankshaft. Stirling engines operate...

Beautiful Boconnoc

The good weather that we had for the Boconnoc Steam Fair in July is now nothing but a distant memory. Everyone I spoke to said what a great event it was. In previous years, some have said that the atmosphere was a bit "clicky" and that previously the organisers were only interested in the steam engines but this year there was a good overall balance and no complaints about unfriendliness. There was a fine range of exhibits, too, although decent autojumbles seem to be things of the past. Everybody seemed to be there. If you hadn't caught up with old friends for a while, here they were, polishing their cars or riding on their tractors. The surroundings in the great park are magnificent with the big trees and rolling landscape down to the house and the lake. Some of my neighbours from up the line called Boconnoc Bock O'Nock when they moved down here and those of us who should know better have started saying it, too. It should be said like B'con'c with the ...
