All being well it will be great to welcome Doug Nye back as interviewer, moderator. and presenter  of some of his recent  motor sport  finds and rarities.

this may have been mentioned here before (apologies) if so, on Autodiva from france, there is a thread on Francois Migault, driver of the Connew, with a number of photos I've not seen before. one has to register to see them, so cannot do a link.

We are making good progress with our DFV engine castings. I spent much of today drilling holes in the two cam covers and tapping threads into some of those holes.

Peter aims to make the engine indistinguishable from a real one although as aluminium castings shrink on cooling, the engine will be about 2% smaller than a real one, but probably just as heavy, despite the fact that it will have no crank, pistons, valves, ca shafts etc because the aluminium castings are very thick.

Sorry to say that we have made no progress towards obtaining a Hewland DG300 gearbox. Several people at Richard's film show expressed the fact that they might know someone who could help but nothing has come about yet.

Peter's son Chris shot a video of part of the film show and if you weren't there but want to see what it was all about, click this link to You Tube.



The sound quality is not great - the acoustics in the hall are probably the reason but it will give you a fair idea.

Very good presentation. Very well done and thanks to Peter and Barry. And Doug too.

the only disapointment was not actually seeing the car itself. 

I really hope that they can get it as a runner as Peter said. But a roller with dummy engine is a good way too display it.

Glad the "DFV" is coming on, just sorry I have been less succesful with a gearbox :confused:

Not sure if it'll be of any use, but it looks like someone (other than Hewland) is making parts for the DG300. not sure if they'd make prts for a dummy casing?

Well done Chris Connew making the film -The hall is a big space with a high vaulted ceiling with hard walls and floor the resulting echo  does make acoustics a trial - perhaps if you all came in foam rubber suits ?

 

Next time we will plug the camera sound feed in to the PA system to get  voices straight off the microphones - great effort and it does give those who have not been before some idea of what happens on the day.Even though it is just 40 mins out of  8 hours on a Saturday.

 

Next Film show for you diaries is Saturday 17th October 2015

 

PS they really do need some help finding an old Hewland DG300 gearbox casing if anyone can help at all- be so nice to see it of 4 wheels again.

Re. the gearbox. Would it be possible to borrow one, have it scanned and then "print" one.  You only need the outside. It would need to be painted the correct colour.

Has the date changed, Richard? You said 17th October in your email after the May event.

At a guess it would need to have enough function to support the car and driveshafts. So at least a crown wheel carrier and side hats.

I am surprised there is not a few around, ones that have been cracked or the cases just plain stretched. Big HP cars it seems flexed those cases out of shape with the inevitable cracking. If welded they are then harder and harder to set up the gears. But still perfectly useable to at least push the car around with no gears in the case, diff or gearbox sections.

I used to have a suitably knackered FG casing but it was never returned and I've lost track of it.

Have you tried Peter Smith (PDS, Hewland classic) he's apparently very helpful and must have replaced many casings, so might have something suitable lying around - or could be tempted into some form of sponsorship deal?

As it happens, we have been in touch with PDS. They were not able to help.

We keep getting the same answer. Any damaged boxes are repaired and re-used. Unusable ones are extremely rare. We have a list of Hewland repairers that Peter plans to contact when he returns from a holiday. This list is thanks to Richard.

It would have to be a DG300. The FG won't support our rear suspension.

We are very grateful for all the suggestions that TNEffers have been making about our project.

By the way, in order to get the car actually running, a new DG300 could be required, and they are currently priced at over £20,000!!

If a new one is 20 odd grand you can see why they repair them!
It was so much easier when Roger Hurst was around he'd have dug something up, nowadays most owners of similar cars just say who do I write the cheque to...

Might it be possible to make a wooden or fibreglass version?

Someone somewhere, must have a DG 300 gearbox not in use, however poor/broken /empty the casing ,however incomplete ,and /or with useless internal components.

They were in nearly all F1 cars of that period, in sportscars in F5000 cars and more - hundreds must be in circulation.

 

If anyone has any ideas at all .......do please follow it up and let us see if between us we can find them something at least they can start to work with  no matter where in the world it is .

Peter & Barry are pushing the rest of the car along nicely  but a DG300 gearbox holds the back end of the car on and without it they can go no further.

Initial aim is a car on 4 wheels that looks complete and original for display .

Beyond that the final ambition is a running car that for instance  could run and be demonstrated ( not raced) at such places as Goodwood, Cholmondley etc  and other  spectator  events.

 

So any ideas anyone ? Surely we must be able to help them !

I understand a plastic 3D printed model will not do the job since it needs to support the back of the car.  You could make one by additive manufacturing out of metal but that technology is probably not available and cheap enough to be practical.

 

But if you get a 3D scan of a gearbox (the accuracy is incredible--within a few ten thousandths of an inch), you can turn that into a solid model and then 5 axis mill one out of a chunk of aluminum since it doesn't need to be functional.  It shouldn't be too big a deal to do that if you can get someone on board with a 5 axis mill.

 

Could you get a local university or tech school interested in this as a project?  Where ever people are being trained to make 5 axis milled parts from solid models, they need to make something--why not your gearbox?
