...hopefully you'll remember.

-- Would you have a good idea of the number of turns of the wheel, lock-to-lock? It looks to me to be at least one full turn each way. Maybe 1.1 turns to full lock? 1.2 ?

--Would you know the outside diameter of the steering wheel?

--Can you remember the shift pattern for the ZF box? I'll hazard a guess that first gear would be diagonally left and forward--perhaps like this?:

1--3-5

R--2-4

(BTW, I assume also that the upper four gears would have been in the main "H" (if there was one) so I've grouped them a bit closer here even if their actual "spacing" L, C, R might have been even...). Right? Or bad guess?

----

I realize it's been quite a while since you drove the car, but anything you do recall could help.

Thanks for pondering

[Doug Nye]

Christopher - sorry for the delay. I wrote a response and without my noticing it, the darned thing didn't post.

I just can't remember some of this detail at this range - I think the steering ratio was about one and a half turns lock to lock but next week I'll be going past Beaulieu so I'll try to drop in and check on the old lady herself. She'll remember...

Ok, thx Doug...and give her a nice hug too

[Darren Galpin]

Doug - a completely off topic question for you. A few years ago there was an evening on Channel 4 called "Racing Torque", which featured a series of films ("Sieg Heil Meisterschaft, Nine Days of Summer, the Jacky Stewart film by Roman Polansky) which were discussed by yourself, Nigel Roebuck, Alain de Cadenet and that journalist whose name escapes me. Any change of such a thing being done again?????

[2F-001]

Sorry to jump in here (!) - I taped the entire evening, as I'm sure many of you did, and often play back those intermission-chats. I especially enjoy Doug's remarks about de Cadenet's Dino...
Likewise, the name of the others escape me for now. I thought it was on ITV though? - to celebrate their acquisition of the broadcast contract from BBC? It did a C4 feel about it, though...

There was a later, broadly similar, evening called ''An evening with Stirling Moss'', with informal chats between the films.

I heard a rumour at Christmas, from someone reasonably well-connected, that Moss was not well. Anyone know? Or should I not be discussing such personal matters here? (Please censure me, someone, if appropriate.)

[2F-001]

I beg your pardon, Darren... Channel 4 it was.
Shame (for me) that my 200th post is an apology for getting something wrong...!
I hope that at least a few of my previous ramblings have been useful.

[2F-001]

Sorry - still haven't learned to avoid double-posting...

He looked as fit as a 30 year old when I was talking to him at the Australian GP three weeks ago. If he wasn't well, he's a damned good actor.

[2F-001]

Well that is good news, Barry. I'm glad to be wrong again!

[Doug Nye]

First - the important bit. SM did experience a minor problem which has been treated/sorted and he certainly appeared to be firing on his usual frenetic 14 cylinders out of 12 when I last spoke to him a couple of weeks ago (about the Spa question on another thread).

Second, the TV programmes mentioned were on Channel 4 - the first I thought was the better - the second was the evening with SM. They were shot in Nick Mason's collection garage at Ten Tenths Ltd in North London. None of us knew what we were doing which is perhaps why the first one was better than the second! The other journalist in part one was an impressively thoughtful chap named Richard Williams who wrote a book on Senna and another, recently published, on Mr Ferrari. In part two we were joined by Peter Windsor. Part one was sufficiently successful at attracting an audience for C4's commissioning editor to set-up Part two with SM. Part two's audience - I believe - was slightly smaller, hence immediate jumping out of window in tall building by C4 editor, and NO Part three...

The really nice part about it was that none of us - save possibly Alain de Cadanet - had (or has) any ambitions to become a TV person, and so it was just real enthusiasts pursuing their interest. And yes I really meant it when I made the comments I did about AdeC and his purple-painted Dino. Bloody Phillistine. Save possibly for the Alfa T33 Stradale the Dino 206S body has surely got to be the most sublime envelope shape ever applied to any motor car? It's only a special favourite of mine, mention a Dino 206S to Gordon Murray and he has to go away and lie down for a few minutes...

DCN

[Roger Clark]

As well as his books on Senna and Sig Ferrari, Richard Williams has also published a book on Phil Spector. THere are probably others, but I could die happy having covered those three.

At last some concrete information for Christopher - I have the broken and repaired John Love (and possibly before that Graham Hill) steering wheel here - and its outside dimension is 11 5/16-inches - 288mm near as dammit. The rim thickness by the way is almost precisely 1-inch - 25-26mm.

DCN

[Christopher Snow]

Haha, thx! A bit of gold for me after all this morning. And it had started out to be such a thoroughly rotten day too.

Thanks also for taking care with the measurement--it really does help to have a prominent known dimension common to so many photographs of the car.

These were great evenings - I still have the tapes with them both on. As I have most of the films that were shown on video, the best bits for me were the informal chats - if only those had been longer:)

Another one would be good - maybe C4 would go for a Ferrari evening? Plenty of material there!

[Doug Nye]

Christopher -

49 'R3's Steering is 1.5 turns lock-to-lock -

Gearchange pattern -we think 'cos we could not fire her up - is reverse towards the driver and forward in the nearest plane - straight back to bottom left slot for first gear, then forward, across to the right and forward again for 2nd - straight back into 3rd - forward across into the far right plane and forward again for 4th - then straight back into far right slot for 5th.

'Lottie' sends her regards.


OK?

DCN

[Christopher Snow]

Ok, Doug! Thank you so much. I'll pass this along to all concerned.

Must admit that the info about steering range surprises me--I was nearly certain from this photo that it had to be two full cranks. But now I know for sure.

The gearchange will probably require some rethinking too (should anyone but me be fanatic about getting it right), but at least that might be done with software only in the case of the commercial shifter.

I very much appreciate that you took the time to find out for me. Thank you.

[And if you ever need to know anything vital about an old rundown '80's SAAB, just ask!]


Christopher Snow

[Doug Nye]

Christopher - forgive my ignorance, but what exactly is it that you are trying to model? Has anybody computer-mimicked the Targa Florio course, or Pescara, or San Remo??? That cyber world is a mystery to me, but I am intrigued by the detailed approach you seem to be adopting?

DCN

PS - Mugello, Dundrod, and the short track at Crystal Palace would be fun too - what about the heyday of 500cc racing, Beveridge Park, Kirkcaldy, that would wake the players up ... or try Phoenix Park in Dublin where they used to protect the municipal statuary by parking a couple of concrete filled skips in front of them to 'absorb de impact...'.

Doug here is the grand prix legends free demo it is just watkins glen track
get the 1.2 upgrade and the over 1.4 G speed fix on the same page to start if your CPU is faster
sim can be played with just a keyboard or a joystick but is better with a pc wheel set up

full game has 11 tracks used in 67 points races excpt le-manz parking lot we got 66's rouen and with full game you can add extra tracks N-ring is at max size of lap so no T-F it is tooooo long

most F-1 tracks are made by fans and are free down loads from Avis to Zetwig plus F-2 and F-3 tracks over 50 now more coming all the time
also tracks like watkins have been up graded to 16 bit tex as have cars, skys

did any spares like different rollbars or springs come with your 49???????
how far could adjustments be made to caster/camber and front and rear toe in/out???

[Doug Nye]

Thanks for the gen - some of which, since I am computer illiterate is, I am sure very interesting but in a language I barely comprehend. Sorry.

Spares with 'R3' included a number of wheels and tyres, about 56 alternative DFV camshafts (all scrap), miscellaneous rods and pistons (all scrap), adaptor plates for a Climax FPF 4-cylinder engine nothing whatsoever to do with 'R3', two time-expired fire extinguishers - one empty in any case - a spare screen (knackered), nose and tail wings (battered) and a number - about 15 - of alternative anti-roll bars but only in, from memory, two or three different sizes and lengths.

The suspension was almost totally adjustable through a very wide range thanks to the long-shank threaded Rose joints on both ends of the lower front wishbones, and on the radius rods and on the rear suspension links. I cannot at this range recall what the adjustment range would have been, but it was considerable. I think we also had two alternative lengths of steering arm with the car, but the lengths were adjustable in any case, thanks to more Rose joint/long-shank track-rod ends.

[Christopher Snow]

...Well....since you write for "Motorsport"...and since I was told they sent out a complementary copy of "Grand Prix Legends" to subscribers a while back, I just assumed you had already seen GPL and knew all about it. Is that not the case then?

----

GPL is a 1967-based PC "sim-racing" program, and it is generally considered (still) to be the very best of the genre--not your typical "arcade game" race sim by any stretch of the imagination. It's the very best piece of software I ever bought for the PC.

I've been driving it for three years now, and I take it pretty seriously. Hence my cockpit building project. But it's not really a case of me building something for commercial consumption at all--the sim itself has been out there for quite a while now, and my own contribution, if I can work it out, will simply be to make available a "how-to" guide should someone want to try to drive with more realistically accurate controls.

[In my case I'm currently trying to adapt a commercial racing force-feedback wheel system to more closely emulate real-world practice. For economic reasons the typical "off-the-shelf" wheel and pedal system doesn't simulate what you find in a real car as well as I wish they did...but I'm a bit of a perfectionistrealist compared to most too (aka a "nut"). So I like to roll my own when I can to get it right....]

---

GPL's big claim to fame when it was released was that it had a very accurate internal "physics model" and I'd still say it's true even though we've discovered a few holes in it now. It's very difficult, too, to come to grips with, and unfortunately for the developer was a poor seller as a result (I seriously doubt we'll ever see anything like it again, and even if we do, I'd not expect it to focus on the 60's pre-wing era the way GPL does).

But for those who do stick with it, it's very rewarding indeed. There is a hard core group of several hundred drivers, many of whom can be found racing online every day 'round the clock (the highest rate of participation probably during evening hours in Europe). I'd be surprised if there aren't thirty leagues running championship seasons at any one moment. Real-time wheel-to-wheel racing with up to 20 cars at once. And free provided you have an internet connection (modem alone would suffice and it works surprisingly well).

A fairly high proportion of these drivers (certainly compared to any other sim) are or have been real-world racers. They've driven everything from karts and Formula Fords up to Formula Atlantics and F3 (maybe even F2, but I'm not sure as I write this). At least three fellows have had at least some FA experience--one of these has also had occasion to test a Porsche 962 (he's that left footed braker I mentioned in the other thread--he tells me he shifted clutchless in the Porsche).

We even have at two one-armed drivers among our number, and one of them is quite fast indeed both GPL and in his SCCA Formula Ford (US), where I believe he's won at least one regional championship.

The fact that so many real racers find it worthwhile tells me it's sufficiently challenging and not all that far removed from the real thing (JP Montoya and Dario Franchitti both seem to like it quite well too, although I'm not aware of having raced either personally--perhaps they are in from time to time under pseudonyms). These guys just wouldn't be giving it their own time if it weren't pretty good.

---

GPL's online community has also contributed (almost always for free) a huge library of improved graphics and well more than one hundred new circuits beyond the eleven originals included with the sim (the most worthwhile of those originals had to be the Nurburgring, which was worth the purchase price just by itself--still my favorite cirucuit, all 175 odd turns of it...).

Among the real-world British tracks are we drive are: Goodwood, Crystal Palace, Snetterton (two version), Castle Combe, Brands Hatch, Mallory Park (2 versions) and Croft (3 versions). Oulten Park, Thruxton, Donington and Isle of Man are rumored to be in the works.

Other non UK circuits would be: Solitude, Le Mans (Bugatti and the pre-chicane 67 "Le Sarthe" circuit both), BathurstMt. Panorama, Leipzig, Lime Rock...even Le Mas du Clos for the bike racing fan (very tight in a F1 car, but probably not so bad in GPL's two lower formulas, aka "F2" and "F3"). Several of the Tasman circuits are rumored to be under construction as well.

A complete list including track maps can be found here if you are curious:

http://magnust.d2g.com/

To get an idea of how one of the cars compares graphically to it's real-world counterpart, see this thread (Honda RA-300 in this case...we just got a new version in the last few days.

http://forum.racesim...&threadid=27252

I could go on and on of course, but it probably belongs in another forum to be honest. I do realize the sim is not the focus of the Nostalgia Forum, but it's not hard to see how one bleeds into the other too (thanks for the occasional "cross-subject" indulgence Atlas F1 Nostalgia buffs).

If you are interested at all in taking a look I'd be happy to send you a (free) copy myself--I only bought 16 of them!. Unfortunately however, mine would be the US version, and I think it might suit you better to have the UK version (they work just fine with one another). If you are interested and can't get one through someone at Motorsport, I can probably manage to get one into your hands there from an online source there in the UK. Just say the word.


Christopher Snow

[Doug Nye]

Blimey!

Very, very kind of you to offer Christopher but I doubt that I have the ability any more - and I am almost certain I would not have - or perhaps dare not have! - the time to indulge.

Thanks again - but if my kids front up perhaps I may come back to you???? They will pay, as would I.

DCN

[Christopher Snow]

Absolutely! Probably not necessary though after all--I'm told GPL is still available online there in the UK for something less than 10 pounds (although not always in stock).

http://www.amazon.co.uk/

(Search "software and games" for "Grand Prix Legends" I've tried to put up the direct link, but I continue to get an error.)

You are certainly right too in your guess about the demands it can make on your time....it can be very addictive if you aren't careful...

...and even if you ARE careful too.

----

If I can find a good link to a "GPL movie" I'll put it up here--you can then get an idea of what it looks like in action without having to bother with any sim installations. That would be too much just to get a look.

These would be simple ".mpeg" videos you just download and then watch with Real Player or Windows Media Player. As you would any other short film clip. I'm trying to find one with some nice classical music at the moment, which is a bit harder than it sounds....


CS

[Christopher Snow]

Ok..while most GPL "videos" do tend to sport "heavy-metal" music and constant carnage and mayhem, not all of them succumb to the temptation--you might download these two if you are curious (both set to classical or light pop music soundtracks rather than to engine sounds).

[Note: The picture quality may seem a bit "crude" but this is a concession made in order to shorten the download time and save the host's bandwidth--in practice, the picture is crystal clear in nearly all cases when running the sim].

http://www.grandprix....net/movies.htm

Sam Dobie has put together two experimental short "films" which can be viewed using "Windows Media Player" (andor "Real Player" too, I suspect) to give you an idea what we are up to in the world of GPL--neither requires any installation of the simulation itself or demo to get a peek.

The second, longer film is done somewhat in the style of the old John Frankenheimer film "Grand Prix," and even uses some of those familar split screen effects. It took me about an hour to download on my DSL line here. The shorter film took about half that time and is set to a more purely "classical" soundtrack....

If you are connecting to the net with a modem, the downloads might best be done overnight.

Hope you find them of some interest.

[Phil Lee]

Hi Doug, I run Racesim Central, one of the websites Christopher mentions. There is a huge following amongst PC racing sim enthusiasts for Grand Prix Legends. The screenshots Christhopher posted are of the latest Honda update. There is also a new team, the LEA (Lotus Editors Association), who are reworking the Lotus 49 for GPL. I know several people have been down to Beaulieu to take a lot of photos of the 49 there. The dash on the LEA front page is based on several of these photos.

We also hope to have a stand at the Festival of Speed where we'll be demonstrating GPL.

[Doug Nye]

Well goodness me....

[Ray Bell]

I don't think anyone picked up on this, but Rouen was from 1968... 1966 was Rheims.

Doug, if you have not tried GPL, I suggest you do some time, but if you're anything like me you'll recognise that you simply don't have enough hours in your day or enough life left to have it for yourself.

Yes, it's that good...

[AndreasNystrom]

Doug Nye: Do you know anything about the tirewear of the 1967-cars?.

How many sets of tires did they have to use under a raceweekend, and how badly worn was the tires after the race?, was there any grip at all under the last laps?.

I guess the brakes wasnt so good after 70laps at Monaco either?.


Btw. Rouen was choosed cause of legal reasons i think. The same thing with Honda is named Murasama, and Cooper -> Coventry in the game.

[Catalina Park]

Rouen was used in GPL because the Le Mans Bugatti Circuit is not how people want to remember 1967.

Andreas (check name, yes, it's the right one this time), I'll have to come back to you on tyre wear but there was no restriction upon tyre numbers used for a race weekend. Tyres were commonly feathered and worn but tread still remained - it was unusual to see any part of the tyre tread worn to slickness, unless there was some suspension geometry derangement. Cars of that period were generally so lacking in grip it was barely talked about, even though it would, obviously, be preferred! Handling - i.e. balance in the car while sliding - was the primary requirement. Monaco was always punishing on brakes, gearboxes, drivers, drivers' shoes and especially gloves and hands.

Perhaps these contemporary tyre notes might be of interest?

Dunlop really had their backs to the wall early in 1967 as the new Firestone 108 tyres offered better handling, better grip, better wear and enhanced lap times.

For the Belgian GP at Spa the H16 BRM was fitted with 27.35-inch diameter Dunlops and was geared to reach 198mph at 11,000rpm. On the dyno pre-race the engine used developed a maximum 388bhp. Firestone could only offer low-profile tyres which could not be fitted on either the H16-cylinder or V8-cylinder Tasman BRMs.

Goodyear offered a version of their 154 compound in suitable sizes, which would give a 27-inch overall diameter rear tyre. Dunlop offered their standard tyre in 006 compound (dry) or 970 compound (wet). With 15-inch wheels fitted to accommodate larger brakes the P261 Tasman BRM pulled only 9,600rpm as compared to 10,100 on smaller whels and tyres the previous year.

Stewart lapped at 3:35.9 on Dunlops, then on Godyears he ran out of fuel on his first lap so could not set a comparable time, but he commented as follows: “Breakaway on the Dunlops was sudden and vicious in the slow corners and I daren’t take risks in the fast 150mph curves…”.

On the Goodyears even his brief experience persuaded him that the car was faster on the straight – 11,000rpm and lifting off! – handling was “nicer and more predictable”. Photographers told the team the Dunlop tyres could be seen to be deforming on the long straights. Brabham reported that when he came up close behind Stewart he could actually see the tyre sidewalls pulled an inch clear of the rims. Dunlop admitted this type of tyre had NEVER been tested on their high-speed test rig. Both Jackie Stewart and Mike Spence said “Forget it” when asked about their willingness to use the Dunlops again. Next time out on Goodyears JYS clocked 3:34.9,

Any interest???

DCN

[AndreasNystrom]

Wow!. Thanks. That was a really nice story!.



So there was tire-war already then?

Actually I did a Grand Prix distance at Le Mans Bugatti during a bout of Insomnia the other night. Who knew! I thoroughly enjoyed it and made some great overtaking maneuvers during the course of the race. The track isn't half as bad as people say it is.
Pity the suspension on my Ferrari collapsed on the 3rd last lap while I was in 3rd behind Brabham & Hulme admittedly not challenging they were to far ahead.
Both Clark & Hill fell out with mechanical problems with their Lotus how is that for realism.

David you are 100% correct with what you say. But how can you have a English name of a French region and call it a different name than the French themselves. I choose to reject this ridiculous situation and use the correct French name.

If one is not using the umlaut over the first 'u' then 'Nuerburgring' seems at least halfway acceptable to me. What really gets up my nose - for self-evident reasons - is national newspapers referring to the place as 'The Nuremburgring'...

David make no mistake you are in the right here and I am in the wrong. I am just being idiosyncratic.

[Carlos Jalife]

The GPL is great, even though there's no Surtees and Stewart (not cheap enough I was told), but there's a Pedro there driving a Coventry (I gave them the picture too). And ray is right, not enough hours in the day to really master this thing.
Just adding to the name things. Pedro died at Nuremberg, and now a german find in other thread says its actually Nürnberg, the Nünberg 200. So if we are going to be geographically correct Which sounds like politically correct to me, please put the accents in México every time you mention it and please Pedro and Ricardo also had an accent in Rodríguez.

[Liam]

you can fix the names (and make the teams more representative) in GPL. Go to http://www.theuspits...les/gplseas.exe
to get a programme to help you do that.

Nürburg and Nuremburg are very different place's, the latter famous for alltogether different reasons.

[Fernando Deutsch]

Carlos,

Did not know that you provide the Pedro picture for GPL. I know Joaquin Solana gave some blue prints, maps and some photos from the Autodromo Hermanos Rodríguez to the Papy guys too. It seems they did a lot of research to create the tracks.

Honda was not in GPL supposed because they did not want to remember the death of Jo Schlesser at Rouen in 1968 with the RA302. About Cooper there was a misunderstanding in the agreement and John thought he have to give the name rights to Papy so said no too. Stewart, as you say, probably was to expensive $$$.

Yeah, not enough time to drive GPL, it is just an awesome thing. If you are interesting in joining an online league of Hispanics please let me know.

Cheers

[Christopher Snow]

I'm guessing Joaquin would be related to occasional Lotus 49 pilot Moises Solana? His son perhaps?

I do believe this is correct re: John Cooper and GPL. He was misleadconfused by the letter the Papy lawyers sent following up on his verbal agreement to have his cars in the sim. So he did not sign, and they were relabled as "Coventrys" instead (we all call them Coopers of course).

Paul Thurston did say JC was pleased later to hear of the "team patch" which put his cars back in as his cars.


CS

[Fernando Deutsch]

You are right Christopher, but I am not sure if Joaquin was Moises Solana son or nephew. Moises was a good driver, but I don't know how good he was at Formula 1 level. He did some races but not that much too give an opinion. Probably someone else here will illustrate.

Is nice to have the Cooper on GPL. The handling is great but it has very low top speed, seems to be an aero thing. Some people said it is too much slow from what it really was.

Try http://www.jsolana.com.mx/index2.html - it is in Spanish though.

El que primeramente incursiona en el AUTOMOVILISMO DEPORTIVO profesionalmente fue José Antonio Solana , mejor conocido como "el viejo Solana", piloto y constructor de autos con innovaciones y adelantos mecánicos para su época, Javier Solana (también diseñador y constructor de autos), Moisés Solana, (uno de los 4 Pilotos mexicanos que han llegado a la máxima categoría de FORMULA- 1), Hernán Solana (piloto de autos, preparador de autos de competencia y piloto de carreras de lanchas) y Pepe Solana, quien sigue los pasos de sus familiares con destacadas actuaciones dentro del mundo de la velocidad.

As far as I understand, Javier Solana was the father and built cars (further detailed on the rest of the site). The brothers Moises, Hernan and Pepe raced. Not sure what relation Joaquin was, but you could try emailing him on joaquin@jsolana.com.mx
