    An Update!!!

    A lot have been going on behind the curtains. First the driveshafts. I never fitted them with the body off because at that stage we were too keen to get the body and chassis mated. I didn't worry much because it only takes 4 bolts on the flanges each side of the g/box and 4 bolts at the wheel ends. What can go wrong? Or how hard could that be? Three days of my annual leave, that's how hard. First I stripped them and pressed the u-joints out, wire brushed them cleaned and sprayed them. Then pressed new u-joints on, 4 of them because there is no CV joints. The side ways movement is taken care of by a sliding spline. Fitting them I started on the LH sideand jacked the car up. 4 bolts on the gearbox side, now 4 bolts on the wheel side. All good but the wheel does not turn. The u-joints bind against there bodies. The problem? too much travel in the rear suspension. Why I don't know. If it was like that I don't know either because it only happens with the suspension travel out to max. It could work like that but not to my liking. I then made up special shock mounts to lessen the travel. 13mm was enough to give free rotation. Now these mounts need to be 4 off because there are double springs and shocks on each wheel. That done the LH side was fine. Now the RH side. I fitted the new shock mounts and started on the shafts. That brought the next problem. The shaft can't reach the wheel end because it lies on the chassis before the bolts at the wheel end aligns. To solve that problem I had to fit a 9mm spacer where the cross member bolts to the block. So the engine is slightly higher on the mount on the RH side. At last that was enough and now the shaft fitted, but only the one way. The thinner way to the gearbox side. So Murphy stepped in once more and yes the LH side one was fitted differently. Although it didn't matter I didn't like it so out with the LH side shaft and turn it around so that they look the same. I don't know who would have ever noticed it but that is why I am my own worst enemy.

    Now the wiring started. I sorted all the wires as far as possible by starting from the front earths. I moved away from standard and mounted 3 earth bars (brass blocks with plenty holes and screws) in the front middle and rear and made sure that they each had a decent earth with a heavy gauge wire because of the fiber glass body. Then I started at the head lights dim, bright and parks, electric fan, fog lights, fuel gauge windscreen wiper washers. Then the dash got its turn and eventually the engine compartment. Now we have the majority working. Outstanding in the electrical side is the Rev counter, no spark if it is connected, oil temp gauge (need to remove the sump and weld a bung on to it because I forgot that when I did the engine), Fuel gauge is not working. Mounting the windscreen washer and fitting horns. Wiring for that is complete. Even the cab light is working on its own switch and on the door switch. It is the round ones that were used in the Dauphines.

    Still to be done? Plenty. All glass can now be done, brakes, accelerator and cable, cubby hole and lid, interior vent system etc.

    The clutch is bled and works fine. Happy with that because I had to make the assembly from a picture.

    Today I completed the cooling system, bled it and left the engine to run a while until the fan came on and went off again. All good. Now I can attend to the alternator connection and go to bed early tonight.

    Frans,
    I know what you mean, there's always something that don't fit as expected. But with your experience, ability and attitude, I would always put money on you finding a solution.

    Fixing problems caused by other people is so much fun! Good to hear progress Frans.

    Funny about the rear suspension travel. You'll know that there are two different shocker lengths for the front of the R8, with two different mounts to match.

    Despite your modesty, I think you can be quite proud of "own worst enemy"!

    Do you now have spark AND rev counter?

    Cheers

    Hi All,

    The Matra has reached a milestone today. From tracing all previous owners, right to the guy that bought it new, and tracing the travels of the Matra I am almost sure that today was the first day in 36 years that it moved on its own power!!

    I could get in start it and drive it out of my garage. This doesn't mean that it is almost complete, there are plenty still to do.

    I will post pictures again when there is significant changes in the appearance.

    Regards, Frans.

    Now look at the pics! Finally everything is operational. The car was idling with the water bled and controlling at thermostat temperature with the fan coming on and off.

    The sump was removed and I welded a bung into it (same as those used by PitStop to replace the O2 sensors when they remove Cats.) and the oil temp is now working as well.

    Finally managed to repair one of two rev counters, so that is working as well.

    Next step is to bleed the brakes. At the moment I can drive it out of my garage which is steep uphill, to return it I put it in reverse and then slip the clutch to stop. Windows are high on the list now as well and we have the new windscreen and a new Lexan scratch resistant rear was made for us as well. Then carpets and thats that.

    Hi All,

    A milestone has been reached on Saturday. The Matra was taken out on the road and driven around the block. First my son took it out with me as passenger and on return the smile on his face was limited by his ears, or else it would've gone right around. It pulls really strong. He lost traction going to second and yes I know it is old and hard 15" tyres, but it was without trying hard.

    Then I took it out and he took a video of it. Apart from grating the gears going to second (damn lefthand gearboxes) I was just as pleased. Thinking back, I realised that the engine is running with a substantially higher compression than my Gordini and the car is 200kg lighter than my car. No wonder it gives you a kick in the back.

    All that said, it is not what the car was built for. It is supposed to be a nice driving car to take out on weekends and to shows etc. All that is left to do is the interior and side windows. Some fine tuning on the carbs, valve clearances and so on.

    I will tell him to put the video on YouTube and post the link. He did put it on Face Book and we were honored with good luck wishes by no other than Rene Bonnet himself (designer and builder of the Jet).

    Regards, Frans.

    Great news Frans! And a message from M. Bonnet too. We've been away or I'd have responded sooner.

    Best wishes

    Hi Al,

    Another milestone has been reached, in fact a 44 mile milestone. Being a public holiday here by us and the show on Sunday, my son decided that it will be driven there this time.

    With 5 new tyres, fitted and balanced we took to the open road that turned into a country road eventually and he drove it to a specific coffee shop some 22 miles away. We had a coffee and exchanged some info (I followed in another car for incase) and then I drove it home again. It pulls like a stubborn mule with a Cancer Rose under its tail and all temps and pressures are fine. Slowing down for traffic and cruising behind them is a pleasure with plenty of torque at revs as low as 2k in top gear. Obviously there hasn't been any tuning done yet and it is just as I assembled it for first time start up. The car is very pleasant on the road with a soft but firm feel to it and hobbles and ditches are amazingly and pleasantly absorbed. It is stable and very directional and with the characteristic light steering you feel at ease. I had it up to 75mph and felt no different as the 50 mph. It outdrags my Holden Cruze with ease.

    It is a pleasant relieve for me because the car was in a thousand and plenty pieces and for its maiden run there were only the stop lights that didn't work. That is now fixed with 2 new lugs crimped to the stop light pressure switch.

    The wheels are standard at this stage with 5 new 165/65 r15s on and he will keep it that way for a while because there is still work in future to do before he gets the alloys from MecaParts or similar suppliers. Even with the thin 15" wheels you can see that the wheels are sitting at the outer edges of the body. So Rene Bonnet used all the width that was available to give the car the fitting look with no unnecessary body overhang.

    Hi All,

    We had our Concourse show today and it was the worst day weather wise. It was raining all day from about 10:30. Nevertheless we did it and spent most of the time indoors at the big hall drinking coffee and eating meatpies to justify our seats.

    At the end of the day, cold and wet we returned and I got a text from my son, "We made it into the newspaper"





    That made the day a tiny bit more bearable.

    Regards, Frans.

    Nice to hear.

    I reckon 165/65 is a good choice for the 4.5" wheels. What tyre type did you choose? (Very limited choice in 0z - basically only the Kumho ES01.) Curiously for a mid-engined car, I ended up having 6 psi more pressure in the fronts; mind you, I like a mobile rear. As I've remarked before, Djets are almost ridiculously controllable at the limit.

    With my Djet V (new synchro rings thoughout) I have found double de-clutching from 1st to 2nd (obviously without the rev in the middle) smooths things remarkably.

    cheers! Peter

    Those warning lights are really nice.
    Its thrue that they are sold for silly prices but can be found a lot cheaper if you know where to look.Voyant rouge tableau de bord
    Don't know what they charge for the postage though.

    Besides that I love your work and the (D)Jet is one of my favourites. I remember when the A110 prices started to go through the roof I thought of the Matra as a good alternative. To late again..

    A somewhat extended hiatus in reports.

    How have you (&/or your son) liked playing on windy roads (preferably wet)?

    For me, this is the Djet's total raison d'Ítre.

    Hi Peter,

    The answer is no, the car has only seen motorways so far. Rego is ongoing and the side window ally extrusions remains a problem at this stage.

    It will be a while before we will take it out for long runs into the country side's winding roads but rest assure, I'm looking forward to it!

    Thanks Frans. I doubt that you'll be disappointed!

    Have you contacted Club Djet re bits? I have found them to be extremely co-operative & supportive.

    cheers! Peter

    Hi exocet,

    Did I do the video yet? No not yet but just wondering, did I say I would?

    I was hoping you'd offer, to show all the admiring fans out there what a wonderful job you've done.

    Enjoy!
