Building, racing, crashing race cars with the 750 Motor Club
No photo, but it’s interesting so I thought I’d post something. I sorted the car out to take it to Andy’s to make an exhaust system this evening. With it on the ground, I flicked up the reverse switch and it moved backwards all under its own power. Not that there was very much of that, I suspect the battery wouldn’t last very long without the engine running.
All the same, seems a fun milestone.
I trimmed down the dash a bit and mounted the instruments, so far as they go, to the smaller plate; here it is. The space on the right is for the Palm. Traditionally, I put this on the left but the gearchange actuation lever is in the way. I might change the software slightly so as to move the gear indication to the left of the display, although it might not be necessary.
I’ve been slowly pressing on with the electrics. In particular, I’ve finished doing the engine loom, easily the most complicated bit, which is shown here languishing in the kitchen. This now fits the car and, as you can see, I’ve taped it all up so it shouldn’t be vibrating to bits at the first sight of a working car.
I’ve got the main switch panel finished, as in the photo on the right. All I’ve got to do for the wiring now is to connect to those connectors that you can see sticking into space. The ones that aren’t connected to anything.
Some progress again at the weekend, although whether this is enough is anyone’s guess.
First up, as I promised, are some turnbuckles to adjust the tension in the chain. Here’s one of them, although admittedly it’s hiding behind a bit of chassis. Essentially it’s a right hand threaded rod end, a left hand one, and a length of hex bar with a right hand threaded hole in one end and a left hand threaded hole in the other. You can just twiddle this around to change the distance between the two rod ends, thereby moving the diff carrier and tensioning the chain. There’s another one of these, exactly like this, on the other side of the diff. Continue reading “White stripes”
Still flushed with success from the weekend, it was back to the J15. What’s more, I’ve managed to actually do a couple of small things which is a relief. In particular I decided to finish off a couple of things at the back of the car.
Yet another odd weekend; one step forward, two steps back, two steps forward. Whatever, I haven’t accomplished what I set out to do. Ho hum.
Everything was all going so well too. I assembled the left rear suspension, using all those bearings I made a while ago, and assembled the upright using the nice shiny new driveshaft. Continue reading “Txing”
Nothing to do with the estimable Georg Kantor or his spectacularly clever bit of mathematics that shares the name of this post, but a comment on some additional tubing in the engine mounts.
Phew! I have finished as much of the panelling that I’m doing at the moment, leaving the car looking like the photo here which, I’m sure you’ll agree is not one of my better photographic efforts. Still, it’s the best I could find without venturing back to the (bloody freezing) garage. All of the panels are there now, apart from the seat back and above the driver’s legs. The former’s not there because I want to retain easy access to the engine compartment and the latter because I need to finish the steering column first.
If you remember, I said I was bored with panelling. Well, I am so again. However, before moaning about that, here’s another picture of the diff assembly.
The only difference between this and the previous ones, is that I’ve made one of the spacers that hold the plates in the right position. Of the other two apices of the triangle, one will bolt to the rear engine mounting and the other will have another spacer, but one with a connection to one (or two, I haven’t decided yet) turnbuckles for getting tension in the chain.
