Look at that. I bet you wish you’d got your own twinkly bar stool for Christmas too, don’t you? For some time I’ve wanted one of these in the garage and Anthea bought me one for Christmas, which I think came from that purveyor of fine quality garage items known as Argos.
It’s Christmas Eve (I wish this time of year was still as magical as it was when I was a child) and I’m stretching out the time until Santa arrives by writing this post. Not that there’s much to write about to be honest.
With the engine in bits I could suspend my disappointment and get on with other things. First up is to sort the wishbones that I’ve been meaning to remake. This is to get rid of the Delrin bearings, which haven’t really worked, and hopefully to get a bit of weight out. So, making my usual MDF and bracket jigs I remade the rear upper wishbones, as seen here. You’re right, they’re awfully short (although you have to add a lot of length in the rod-ends to this photo) and this is what completely re-designing the rear of the car would have sorted. However, I just don’t have the time, especially as I’ve just got a new job. (As well as still teaching, this time to “Engineering Doctorate” students, up at York and my PhD viva being next week. Eeeek.)
I took the crank up to Andy yesterday to see what he thought. As I was beginning to suspect he reckoned that the #2 and #3 big end journals were toast. This is a real bugger, as you can’t get undersized shells and therefore can’t get the crank reground.
Finally, I was getting to the root of the problem. And, indeed, demonstrating that it really was a problem. First thing, though, was to close up the top of the engine. So, I took off all the cams and drive gubbins, put the followers somewhere neat and tidy and put the cam cover back on. All this so I I could up-end the engine without the followers falling out. What’s more, with the cams out I can twizzle the crank around as I want without worrying about the pistons bashing into any valves.
So, I took the engine out, intending to get to the bottom of the oil pressure issue. I’m getting reasonably good at taking the engine out of this car, but as usual you always end up with a quantity of fluids falling out and making a real mess of the floor.
I’d got myself all ready well in advance, here’s the car sitting on the trailer and, after a morning lecturing to students. I jumped on the train, zoomed down to Cambridge and drove to Silverstone. There, miracles of miracles (they must have got some new security guards) we got in easily and parked up for the night.
And so, after a season of frenetic car building, engine swaps and sundry other excitements the RGB year ground to a halt at Cadwell at the weekend. It was, yet again, a wet weekend although a very enjoyable one. That the club managed to get 26 races on track over the 2 days, along with all the qualifying sessions, is a testament to how well organised it is. For something that only has two paid staff (and lots and lots of volunteers) this is pretty miraculous.
Since I was last here I’ve been pressing onwards, and missed the RGB meeting at Donington last weekend. Anthea and I went up to watch and got burnt in the sunshine while watching the RGBers swooping down the Craner Curves. What’s to bet that when we go back there later in the year it’ll be raining, like it’s doing at the moment? More importantly, it’s now not long until the meeting at Snetterton which I’m aiming at for the newly engined car.
As a couple of people suggested to me, I made a support for the standard-sump equipped engine as in the photo here. This allowed me to support the engine in position to see what I was going to have to do to make some engine mounts.
Note that I’m using a motor sport magazine to get the support at the right height.
