Just to finish up (hopefully) the subject of our mystery brake illness, it appears to have 3 possibly interconnected issues.
First, we believe that in the tube that connects the front brake cylinders which loops upwards over the stub axle, we had trapped air, despite all our bleeding efforts (pun intended smiling smiley ) Because air expands when heated, this was causing our brakes to gradually bind. Second, the new drums were not good - And had to be reground so they were true. This was causing some of the heat build up which led to the binding. The rear brakes needed work also - We had been leaving this till "later" - ie after we got the fronts sorted, but it turned out that they needed to be fixed first in order to get the front ones right.
All very interesting. It seems we now have good brakes to go along with our good horsepower, so hopefully we are ready for our shakedown rally out in Alice Spings in 2 weeks time. I will be towing the Healey out there next week so that, just in case we have any issues, we can get her home ! Only 3700 kms each way - Just round the corner !
The details of this next part of our Adventure will of course be on our blog, but if you want to read more about the COT (Classic Outback Trial) you can find details here COT

Stone the bleeding crows mate 3700 clicks is just down the road a bit . Was reading Noel Gorm's blog re driving his 100 from Perth to Bathurst in April for the annual rally where after fueling up in Midland WA he sets the sat nav for Norseman and the sat nav says to him " Travel for 541 kilometres , then turn right " .How many places on earth apart from Oz would such long straights exist , before changing direction and turning either left or right . Another bloke drove from Cairns and back , which was only a short 6500 k's round trip . Glad you've sorted the anchors on the flying machine for your little trip around the Alice .

smiling smiley Where are you in Sydney, Wayne ? I will be dropping an empty trailer off in Tennyson Point early next (not this) Friday afternoon, and then heading over to St Peters to load up the Healey so we can leave early Saturday 11th morning. Give us a holler if you are nearby.

Hello Giles

Would like to organise a test drive for the next Australian Austin-Healey magazine.

Can this be arranged?

Many thanks

Would think it would be no problem, Patrick. But since the car is currently with Ashton in Sydney (ie he has the keys !) I will cc him and you on an email to confirm.

Giles

PS My apologies to the Admin - I just inadvertantly replied to Patrick's above message thinking it was an email on my phone, so hope this doesn't "lock uo the Forum" !!

I will be leaving Qld on Thursday and will try to get to St Peters by about 10 am on Friday, or after the rush hour. I have to drop a trailer off in Tennyson point first. Will give you a call when I know my ETA for sure.

Having made it back from the Classic Outback Trial some 3 weeks ago, I am STILL cleaning Red Dust from every crevice ! I am surprised there is any left out in the desert !
Since we got back we have been working on a roll bar. We feel it is just too risky doing an event like the P2P travelling across 2 continents and half way round the world without some kind of protection in case of "the unforeseen". Many of the past P2P competitors who we met on the COT recommended it as well. The problem is that to make a fully CAMS (Australia's national motorsport governing body, affiliated to FIA etc) compliant unit would mean forward bracing into the foot wells, and would generally be very difficult to achieve given that we also need storage areas and we are running slightly larger (read "more comfortable" !) seats. There just isn't room to also enable us to live in the car all and every day for 36 days. So we came up with a compromise.

It is braced rearwards by 2 bars that go through the shroud but INSIDE the rear roof clips, and then mounted on large plates on the cross panel where the spare sits. (This panel is already reinforced underneath with 1" square steel tubing). The upper bar is curved the same as the rear roof stay, and that rear roof stay has been removed (it can be refitted if required). The convertible roof hinges have been replaced with slide-in sockets (visible in photo 5) so the roof can still be fitted, but is just slotted into place. When not in use, it will be strapped behind the roll bar. For final strengthening of the roll bar, we have diagonals, and also will have an extension rearwards from inside the rear shroud back down to the two chassis extensions at the rear of the boot.

Finally the entire roll bar is quickly removable courtesy of sleeved joined just below the rear shroud, and also on the supports mounted on the inside of the rear wheel arches.

The other benefit of the roll bar will be that we can fit a clear perspex screen across the back which will hopefully inhibit (or even prevent ?) the ingress of dust and sand over the back when we are travelling with the roof off, which will be most of the time. Will need to do some "wind tunnel tests" (ie drive on dusty roads) to see if this works !

Should be finished next week so we can get on with the other stuff we need to do !!
Attached pics show the roll bar taking shape (1 & 2), the position for the rear support bar (3), position for the rear stay supports (4), the mounting backets on the inner wheel arches (5), and the tacked bar in place (6).

And we are also changing the seats. The new "classic / retro" design seat that we had fitted just weren't working very well. Seat base too high, seat back too low, and not only uncomfortable as a result, but also not really very well made, even though they are Corbeau. They may be fine for an occasional jaunt on a sunny day, but for some serious work, they just didn't cut the mustard.
So we have been looking around - MX5 seats (Miata to some !) were touted, as well as others, but we ended up being offered some MGF Trophy 160 seats that were "surplus to requirements", and after some minor repairs we have been playing with these while the roll bar is being fitted. They do fit, but are a bit too wide to allow much "fore and aft" sliding, but this is kind of irrelevant because one always needs to be as far back as possible in a Healey (unless you are very short !), and Ashton and I are both over 6 ft. So we plan to bolt them directly to the floor, hinged at the front so we can easily tilt them to allow access behind the seats to the battery etc. They do have a seat back "tilt" function, but as this is operated by a more cumbersome wheel than just a lever, is more for comfort adjustment than access.

By removing the runners (a cumbersome job with an angle grinder because they are welded / multi-rivetted in place) we have got the height down to about 160 mm at the front, as compared to about 275 mm for the current seats. Even if we tilt the front up a little to provide more thigh support, the back will stay similar so this will provide us with considerably more headroom inside when the roof is up, as well as making sure we are below the level of the roll bar. More importantly it also means we are looking through the windscreen rather than at the chrome trim along the top !!

We will find out if they work shortly - Like everything else on this car, it is a case of experimentation for things not often done before !!
Pics show the seats side by side (with runners), height comparisons (without runners), and then a measurement of the height of the MGF seat vs the Corbeau.

Our roll bar is finished and looking good (photo attached) - Just a small hiccup is that one of the rear bars that go back to the chassis extension rail fouls the filler cap for the auxilliary fuel tank ! Bit of an oversight as we had the tank out while they were welding on the car - And it just never occurred to us that it wouldn't fit - Until I went to put the tank back in !
But we are getting there.
One question for those who race these cars, or otherwise stress them to their limits. There are left and right hand steering levers (see attached photo) that are bolted to the front stub axle and then connect to the side (steering) rods, and then the single centre (steering) rod. I understand that the steering levers are apparently cast steel, while the steering rods are steel tube. If cast, then my understanding is that the steering levers cannot be welded if they break.
During the rally out in Alice Springs in August we hit a (presumably) large rock with our left hand front wheel spinner - And since the spinner is as far outboard as you can get, the leverage forces on the steering when we hit the rock were much greater than if we had hit the rock with the wheel or any point further in board than the spinner. The resulting damage was that the toe out went quite extreme (30 + mm) - Something was obviously bent.
When we finished the stage and got a chance to inspect the damage, it was evident that the LH steering lever had been bent slightly, enough to throw the track out considerably. The two long steering rods and the longer centre steering rod were not bent - Just the cast (?) lever.
This really surprised us as we thought it would be the long rods that would have bent first. And it got us thinking - Is it normally these steering levers that bend first when the steering is hit ? Or do the longer straight rods normally bend first ? Has anyone ever broken one of the cast steering levers ? In other words, do we need to carry a spare, especially if they are "cast" and cannot be welded and mended if they break ? Or do they survivie pretty well ?
Opinions on which are the weak points of the steering would be much appreciated, especially if anyone has ever broken a steering lever rather than actually just bending it.
Appreciate your input.
Giles

Another technical question !
We are looking at carrying a Davies Craig electrical water pump with us as a spare in case of any water pump issues en route. The idea would be that we could just plumb it into the water hose if we need to.
We are looking at the EWP115 model which pumps up to 30.4 gals / 115 litres per minute. (Note, these are imperial gallons !!) Davies Craig Water Pumps
I have been trying to find out what the approximate flow rate is of a standard water pump but can't find anything. I realise that the output is dependent upon engine (and therefore pump) speed, but surely there should be a known flow rate at X or Y rpm ?
Anyone know what the standard water pump flow rate is ?
Thanks,
Giles

I know I'm not answering your question but one thing to consider which you may have already done.
The most likely failure of the water pump is of the seals of bearings.
If that happens you will have to remove and disassemble the pump try to block all the holes in the casting and refit it before the electric pump will do you any good.
Maybe you should install the electric one from the get go as the repro pumps, which is probably what you are using, do not have a great reputation for reliability.
