Some experimentation shows that there is a problem with air in the master cylinders not getting out of the exit ports. I had a peek down the inside of the master cylinder I’d nadgered and indeed the exit port is a pretty small hole at the top of the cylinder. Experimentally, I loosened off a couple of the master cylinders and jammed it in in a horizontal position, as in the photo.

Flame on…
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.
White stripes
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”
Brake, turn in and…
I’ve been pressing on, although I don’t seem to be making sufficient progress to make me feel comfortable. Still, some things are happening. I have, though, managed to completely finish the hydraulic side of the braking.
So, here’s a nice shiny picture of the final arrangement of the master cylinders, lurking at the bottom of the footwell.
Snowed in
OK, I’ll admit that I’ve been a bit remiss lately, but there’s a good reason for that in that we spent last week skiing in Switzerland. Of course, that means that next to nothing got done to the car.
However, here’s a picture of a few alps as taken last week. The only problem is, I want to go skiing again; although I smashed myself up skiing a few years ago it’s still fantastic when it works right.
Another day, another panel
I’ve nothing to say really, but posting things makes me think that things are moving forwards, and I can continue whining to you lot about the tedium of panelling.
I added another two of the little b*******s to the car today, the first being the “shoulder” panel in the photo. By the way, in the background you can see the Fury sitting there all unloved and neglected. However, I’m going to have to start re-invigorating it soon. I’m hoping to get the J15 to a rolling chassis versi0n fairly soon so as to facilitate that.
All on my ownsome…
There’s still no chassis here, so I’ve been getting on with other things. i did phone up the powder coating company on Friday afternoon when it became apparent that I might be able to get over to Soham. However, there was no answer so I guess they’d gone home early. Either that or they’ve gone out of business taking my chassis with them… 🙁
Here’s something though, in that I’ve finally finished the rear brakes. The new taps I ordered arrived and I was able to properly cut the threads. I did have an experiment using helicoils but, for some reason, I didn’t feel confident about it. All the same, I’ll keep the helicoiled part as a spare.
Bored, bored, bored
This is boring, really it is. I’ve got to that bit where I’m making the panels for the chassis. I haven’t sorted out the powder coating yet so I can’t actually rivet anything together but I am nonetheless making the panels.
And, it’s boring; did I say it was?
Just take a seat, will you?
A thing I’ve been concerned about for a while is whether the seat belt mountings are OK for use with the HANS device, which requires that the angle of dangle of the belts between the HANS and the mountings is within 20° of horizontal. So, I installed a seat (that is, the old blanket that I use for such things) and took a video of myself sitting down in the seat in various ways. The photo on the right is an image capture from this video, which I made with the video camera I inherited off my Dad.
Now I come to think about it
In the cold, hard, light of day there’s another possibility for the brakes. I could tap the caliper mounts in the uprights, as shown here, for say, M12x1.5 and I could then fasten the caliper mounting blocks directly into the upright without needing a bolt head on outside in the way of the disc. That way I could use the sort of discs that I’ve got on the back of the Fury and I’d be sure they’d fit under the wheels.
This is essentially how the front brakes on the Fury mount to the uprights (ex mk II Escort in that case) so it must be possible to make it work, especially with the addition of copious amounts of thread lock. Certainly seems a decent idea…
