I have been busy. Mr Schroder's cranks are 110mm long, and my pocket calculator tells me that if I use one of the 29er tyres which my wife doesn't know I retained from her perfectly good gentleman's mountain bicycle when fitting it with tubeless tyres, then these tiddly short cranks will give me the same pedal speed as a 44 inch gear. It's going to have a 406 back wheel so we're not going to call it a penny farthing. We're going to call it a one-and-six. - D'you remember pre-decimal coins? I have the last letter from the chap who designed the thruppenny bit. He signed it. The coin. - Though he signed the letter too, obv.. - He signed the twenty pence coin too. You'll need a magnifying glass but they all say WG on them. He designed all the Falkland Island coins too but I've never been there so I can't say if they have WG on them. He was called William Gardner and he died on almost the last day of the century and wrote to me a fortnight before. I shall not say why he was writing specifically to me though it happens to be true and there happens to be a reason. I like to intersperse my blog with a bit of mystery. -
The front wheel has a Campagnolo Lambda Strada aero rim and the thirty-six stainless spokes that came with it, nine of them slightly munted from an escaped chain, but now unmunted with a pair of pliers. - I said I was Mr Mean-Pants. - This is because
a) it was given to me
b) aero rims are stiff
c) the air flow will be better and I will be able to go at 8 mph instead of 7
d) the edge of the rim is gouged but this machine won't need rim brakes
e) it will annoy Mr Knight.
Mr Knight, in passing, likes all things Campagnolo and would eat his dinner off their plates if Campagnolo made plates. He owns a complete Campagnolo tool set. It is better than this tool set for making bikes but not as good for making pianos. I digress.
The back wheel has 48 spokes for no good reason other than that I found it somewhere. Can't remember where.
The penny trike had split bearing housings but when I clamped them up tight they turned the bearings into very slight ovals, so this machine has bits of tube welded to plates which screw onto welded extensions of the forks. These extensions were welded in after the wheel was built and mounted, lest the wheel ended up at a curious and vexing angle. Vexing angles often happen, I find, when I'm the welder.
Finally, the frame welded itself into existence, an exercise principally in using up odd bits of sawn-up bike frames that otherwise belitter the workshop. And then it got left outside the kitchen door where it was found, on his return from school, by someone who promptly took to riding it round and round the house, somewhat inexplicably singing there'd be blue skies over, the white cliffs of Dover.
