I may be old fashioned, but I thought best practice was to design a structure by calculating the forces applied and the resultant stresses, strains and deflections. Then build it, test it, optimise it for strength and weight, and then sell it.

Attaching a 1.5m section to the seat fixings(??) and adding a 70kg weight to the end does not seem very scientific to me, especially at this stage of the manufacturing process. Surely the main forces will be fed through the suspension system not the seat mounting? Also 70kg at 1.5m is about 760 ft.lbs in old money, what would you expect from a decent chassis, 3-4000 lbft/degree of twist maybe? Much higher would be better, even the old Lotus Elan had about 6000 lb.ft/degree if memory serves, for a 1600cc engine.

Surely a qualified and reputable engineer should be able to quote strength, stiffness and other design criteria for a chassis that he was producing and selling?

Finally, Autocad is a primarily a draughting package is it not? Does it have much in the way of finite element or similar stress analysis capability?

Graham,
We’ve both missed some of each others points. I’ve taken another look at a photo of Si’s chassis and see that you’re right in saying that there IS in fact a box-section member straddling the chassis. In this respect I was wrong and apologise to both you and Vince.

I still believe I’m correct on the ‘cancellation’ issue in that it is the difference in these forces that is the torsion load under descussion.

We all know that my fundamental problem is that I’m not happy with the claim that this chassis will handle better than the original (and excellent) Python. When the truth is that nobody (least of all Fib’s and Vince) are in a position to verify such a claim. Remember that this claim was being made almost two years ago (and consider why). As I’ve repeatedly said, and as I think has been accepted, my intention is to expose Which Kit?’s lack of integrity.

I don’t have a problem with Vince, although it seems that he has one with me that has been festering for years. I put that down to who he’s been talking to and believing.

WhichKit said:
. . . . a constant brainwashing misinformation process which unfortunately the gullible public will believe.
My reputation has been sullied in the eyes of Vince by such propaganda to the point that he’s never spoken to me.

Pity, me thinks .

I wonder where it goes to from here. Presumably Vince’s next complaint will be that I didn’t test it till after Which Kit?

it seem that my point was totaly missed ,den is saying that the suspetion dose not work and the loads donot cancel ,my "very basic test " was to show that the force in the suspention where acting in a way that stops body roll and there for maximises the contact with the black stuff !!
and i never said that i had no engenering qulifications ,so what do you have then den ???
HNC ONC degree ???
i have spoke to you but your selective memory seem to have forgot !! and it was a painfull experence then too!!
one reasion i did not want to do it again ,seems i am banging my head on the same wall as befor

,and as for all the computer stress tests and therory of stress it never stoped the sace shutle from falling out of the sky ,or merc "A" serises from rolling over ,only during use did the "tec" guys say oh that should not of happend ,
and as it gose i have HNC in engenering ! not bad for a Dyslexic!!!!!

and as for the braintree show i was the closesed manufacture and was never even told it was on ! guse this was so i did not say "HAY THATS THE SAME DAY AS KENPTION THAT I BOOKED MONTHS AGO " was it not or was it the case that you just forgot that i was there at all as you have since i started .
not sure this is a good idear as with my dyslexia i am going to say things that make sence to me but others take totaly wrong ,as unless you have the same as me you can only see things in 2D and not as a hole as i see thing in 3D with all the loads and stress directions in full 3d in my head ,that is why letters are so hard for me to see as my brain pics them up and looks at it from all angles . I know what i can and cannot do .
and i take it that not one of the people on this site has ever been in a car of mine??????????????

Vince,
I know that I goaded you to take part in discussions, but I had no idea that you are quite as embittered and ignorant as you’re making yourself look.

If you want my advice. Think about your posts. Say half as much and you’ll look twice as clever. As it is, I don’t think you’ve done yourself too many favours.

Putting it bluntly, you've confirmed my position on all my substantive points. I'd be interested to know what part of aeronautic design you've been involved with. Wouldn't be lead baloons, would it?

Den.

We've already established that the chassis will still be subject to upward shock loadings acting at the rocker arm pivot points. But as explained, with rocker arms these upward loadings will be far less than the upward loadings hitting the same bump would produce with outboard suspension, which in turn means the torsional loadings on the chassis will be far less.


No, absolutely wrong. Irrespective of where the shock absorber is mounted, the chassis will be subject to the same twisting forces if one wheel is raised further than the other. The only thing that would lessen twisting forces would be if the two front suspension units were linked together like e.g. a the Hyradagas system used on the metro so that as one wheel moves up the other moves down.

I was really hoping that Vince would apply some reasoned argument against Den's points rather than becomming personaly abusive. IMO this only shows that he has no answers to give. FWIW diasters such as the Shuttle were largely not caused by simple engineering issues, but far more by political issues. I also doubt they tested the shuttle by kicking the tyres and saying "yeah,...seems ok". Running a FEA on a chassis is not that expensive these days.

Mr2Mike,
Thanks, I’m heartened to see that someone else can follow the essence of my argument.

John,
I don’t think Vince is a troll. Sadly, I think he’s showing his true colours.

All,
Vince places a lot of emphasis on the Braintree show date clashing with that of Kempton park in 2000.

In late 1998 I’d issued a writ of summons upon Mr Filby because, curiously, he’d said my Sumo chassis “wasn’t up to it”. One result was that Fib’s barred me from the Stafford show in March 1999. He threatened to ban me from Donnington in September 1999 too. However, I cut a deal with Fib’s along the lines that he would not bar me PROVIDED I ran it’s advertisements. After I’d run those advertisements Fib’s changed his mind and barred both my companies after all.

I resolved that my only choice was to run shows of my own in 2000. I purchased the rights to run Harrogate and attempted to buy other shows but was unsuccessful. So I set up two new shows at Malvern and Braintree.

It’s difficult to get dates as well as venues. July and August had one show. It was initially held at Sandown Park in August the popularity of that event declined year on year and was moved to Kempton Park in 1998 for financial reasons, were it was run in August. The 1999 event was moved to run in July by John Cooke on behalf of the ASCM (its owners). It was a commercial flop. John said that it would probably not be run again but IF it were it was to revert back to its established date in August. John was adamant that the move from August to July was a big mistake which would be switched back IF the show was to run again.

Accordingly I booked the Braintree venue for July. Nearer the time of the event, when publicity was about to start, I telephoned Peter Bailey (spokesman/chairman of the ASCM, the owners of the Kempton Park show) to ask him IF the Kempton Park show was going ahead and IF SO on what date (such that it could be inserted in the Kit Car magazine show listing). Mr Bailey said that he didn’t know BUT that there was to be an ASCM meeting to discuss the issue 2 weeks hence. One week later the February 2000 issues of both Kit Car and Which Kit? were published. Both contained announcements to the effect that these shows were scheduled for the same weekend in July. Curiously the Kempton Park show was not simply being supported by, but was actually being run by Which Kit?

The argument used against me was that I’d ‘stolen’ the date without checking and was vilified for it.

Vince says that exactly the same thing happened the following year. That’s simply not true. There wasn’t another Kempton Park show.

I’m still barred from Fib’s two shows too!

I'm sorry Den but in the nicest possible way isn't that a bit 'pots and kettles'?

Jeez mate, if your posts were conversations I'd think you could talk underwater!!

I knew I'd regrett having a quick last look on here.

Like the man above says, pot calling kettle black.....

You have done nothing but try to enduce arguments on this forum (very successfully) you are also in the magazine publishing industry which makes you much more able than others at this mudslining.


How exactly is this helping the industry?.... Oh yeah advertising integrity.

So does this mean that all adverts in your mag will receive the same attention.... (even the ones you print without the manufacturers permision)... and do you amend any other manufacturers adverts that you print.

I'm especially interested as I got a broshure from one manufacture of a car they were developing and it contained claims like "0-60 is already under 4 seconds and if you get carried away with speed the XXXXXXXXXXXXX will stop from 100mph in around 2.5 seconds"
Very wild claims with no chance of achieving IMHO(except in dreams) thats 2 seconds quicker than the XTR2 and radical (which are similar).
Should you be gunning for this co as well? I personnelly don't think so as I would sure ask 'how did you test it', just like I'm sure potential Python owners would ask 'have you got a demo car?'


Makes me wonder if your other clients the advertisers are waiting to be next, after all which ones have we seen on here supporting what you are doing to RV (I don't have time to read everything)!

As far as I'm aware your major gripe is that the Python add implied it had been driven, but as you like to point out with your posts, it never stated one had.
Also you don't like that PF is involved, but exactly why does this matter if the end product is as promised to each customer?.
You also won't accept Vince's word about RV ownership, I have to ask why would he lie?

Finally your mag has written good things about the RV dynamics Nemesis... a car that was in fact the prototype with no chasis or body amendments i.e. the same as your first Sumo. surelly this counts for something and warrants a little more respect.

So why come back and fuel the arguments if you regret it?

And you think that printing blatant untruths is acceptable?

So, how exactly would you propose finding out that an all new design had superior performance and handling without actually testing it?

andycanam said:

Vince may well be a 100% genuine guy with awesome car designing and building skill who hasn't quite mastered the art of reasoned argument yet. Or he may be something else entirely. His outburst didn't impress me, at least not favourably.

Surely the point is not whether the manufacturers advertisements are 100% factual and correct, some artistic license is expected and taken into account by potential purchasers. The thing that would concern me is the added credibility given by supposed informed and impartial editorial coverage. Even more so when the praise relates to a product that at the time was not developed or available for test.

As I said before, whatever the rights and wrongs of bits of the arguement, surely the core point is indisputable?

The 'core point' being that Filby is not to be trusted?

Sounds about right.

Andy,
I thought you were credited with a better analytical mind than is evident in your outpouring above.

I thought that you’d be happy that the argument is finally settled, but instead you seem set on creating a new argument or ensuring this one doesn’t die.

If you want a new argument then take it to the Advertising Standards Authority.

www.asa.org.uk

They have a simple on-line complaints form where you can complain about overly optimistic acceleration or deceleration figures or anything else you think is wrong in an advertisement. I’ve looked through the most recent Kit Car magazine and don’t see anything that I’d want to complain about (much less argue with you about).

As to prolonging the present argument to cover the extent of Fib’s involvement/interest. Where would you like it to go? Isn’t it sufficient to see that Fib’s has advertised Python for 2 years, fed his readers with bullshit, compromised the integrity his magazine, biased its coverage against Python’s natural competitors and subjected himself to ridicule in the process? He’s done/been through all that so that you and I can hypothetically argue about why, has he?

Somehow, I don't think that was his motivation. I reckon he was motivated by an economic interest. You got another suggestion?

I don’t know why Vince is keeping Fib’s out of the frame. Don’t really care either. You may ponder that point yourself with yourself for as long as it brings you pleasure.

Me, I’m off to bed

Nite, nite Vince and all my other buddies

This is the last i will bother with this ,and yes you are all right "I am NOT good AT GETTING MY POINTS OVER" and if any of you had bothered to look at the site that i pointed out you mite of understood WHY!!

DEN you still have not said WHY you never wanted anything to do with my cars ????

YOU have never given a good reasion for messing around with all the shows (other than to get at filby )

YOU just keep on with your "Which HUNT" or should i say "WHICH KIT HUNT"
and we are all GUILTY untill proven INOCENT!!!

and if i dont like or trust you after all what you have said about me and my products then i think i have that right !!!

so i Will leave you guys to talk amoungst your selves and "Hang " all that you want!!

i think i have good reasion to feel a little mad at times !!

So as i said the proof is in the eating so you will all have to see once the car is on the road and the track !!! and then YOU CAN BURN IT AT THE STAKE FOR BEENING A "WHICH" or NOT what ever you want???

may still send Graham some more pictures as he is much better at getting it across.

Den - you have already said that dave Pepper was taken for a ride by PF , It has also been said that he whent out of his way to try and solve some of the problems (that was said by someone who was owed items ). Could it not be the same with vince . From my experiance people with dodgy ways of doing business often use people who have no intention of doing wrong to further their aims . With vince so far away & with his dyslexia
this would make him an ideal target . As far as I can see you have the advantage in right of reply & skills.
He has made a brave decission to move overseas - not something done lightly - but his promoter may used his skills to 'embelish the truth'(sic) I for one would like to see if it vince's fault of whether someone in the UK has been using his business to promote their own ends . (awaiting Dens brickbats)

I'm going to reiterate a lot of what Ozzie Dave said here;

Vince
Thank you for coming to the forum and offering your views etc. Good luck with the car. I hope it is all that you promise.
I know you don't think Den can be trusted , but from everything I have learned about the Kit Car industry, I would be very cautious of your dealings with Peter Filby. I believe he will have his own agenda.
Hopefully Graham Bell will keep us informed of your progress. This way I think we will get the truth about what is going on.

One question that has been bugging me is:
Why did you pick Filby as your promoter in the UK? There are many independent people that I believe could have done a much better job, advertising throughout the industry (mags and websites etc), keeping poeple better informed, carrying out surveys and promoting the car at various shows.
I have said previously, if it were me I would have advertised it initially as a development project, offering the first 5 customers a very good deal on the understanding it was in ongoing development. Hopefully these cuctomers would have some engineering knowledge and be able to offer feedback. But I'm not promoting it.

I trust there will be a demo car?
Who will be building it?
reason for asking: Did anyone see Top Gear last night? Clarkson was talking to the guy from the Kumars about driving in India. Made me think, do they ever scrap cars over there?
