284. The First Signs of Spring
1264 is still safely hibernating in her carcoon, but along with the snowdrops, things are stirring in the woods.
Last week we had notification from the people checking the tacho that they are on with it, and that while they can’t alter the internal configuration to make it read correctly they can fit a little in-line gearbox in the tacho cable to sort the problem out.
This means that the drive to the tacho will go through a 1:1.8 increase in speed between the crankcase and the oil pump; a 3.6:1 reduction between the oil pump and the front end of the taco cable; and a 1:2 increase in the middle of the cable! Go figure.
Of equal significance is the news that the engineers relining the cylinders are nearly done, and they should be back at the Shuttleworth in a week. Everything else is ready – new pistons, new rings – and so it’s only a question of reassembly once Phil’s finished on the Mew Gull engine (which was spitting iron filings at the end of the season). And then we can bring the airframe over and reunite the two. We are hopeful that with all the work that’s done, we may see an increase in performance. What we had before was perfectly acceptable, but wouldn’t it be nice if we could confirm the performance figures generated 100 year ago?
And the third piece of winter work that’s coming to fruition is Stephen Saunders’ film. He has booked the Prince of Wales cinema in Leicester Square at lunchtime on 11 April for the premiere, and we are getting ourselves psyched up for the red carpet (stained with castor oil, of course)!
Things are definitely picking up…
