1984 Minardi M184 Alfa-Romeo by D'Alessio. This car never raced, as the engine deal with Alfa Romeo fell through and was replaced by Motori Moderni.

Perhaps another trip down memory lane for Tony -- Lotus 24 by Allington. Tony, what about the angle on this one? The roll bar is not really visible.

BTW, I recently got to heft a square 4 Ariel cylinder head: LOTS of weight! Big lump of engine indeed.


...egad! Looks like something out of Kafka's "The penal colony."

“It’s a remarkable apparatus,” said the Officer to the Explorer and gazed with a certain look of admiration at the device, with which he was, of course, thoroughly familiar. It appeared that the Traveller had responded to the invitation of the Commandant only out of politeness, when he had been asked to attend the execution of a soldier condemned for disobeying and insulting his superior. Interest in this execution was not really very high even in the penal colony itself. At least, here in the small, deep, sandy valley, closed in on all sides by barren slopes, apart from the Officer and the Traveller there were present only the Condemned, a vacant-looking man with a broad mouth and dilapidated hair and face, and the Soldier, who held the heavy chain to which were connected the small chains which bound the Condemned Man by his feet and wrist bones, as well as by his neck, and which were also linked to each other by connecting chains. The Condemned Man, incidentally, had an expression of such dog-like resignation that it looked as if one could set him free to roam around the slopes and would only have to whistle at the start of the execution for him to return.

45° right (clockwise), and all will be well. Thank you for posting these, I am not certain the Tom West hasn't beaten you to it, but you know what? I don't mind seeing them again!

Edited to change 90° to 45°! I'm not sure that even that is precise, but I don't have any fancy software for turning images through a specific angle.

There you go! If I was to be really picky I would say it need another 2° clockwise, but there is no guarantee that Jim drew it with 'vertical verticals'! We used to have long discussions about how to present cutaways with a bit of difference, and I remember specifically cajolling Jim into drawing the Cooper with the front wheels on full lock. I thought it worked, but Jim wasn't so sure, and although he did, I think, one more with a bit of lock, he reverted to 'straight ahead'. I never did it, thanks to Jim finding out on my behalf, he he, that straight ahead is probably best.

PS. If you remember that these illustrations were done on board that was, I think, 21"x31" ( 530mmx790mm), later to become 20"x30", the rule of thumb was to draw the cutaway as big as possible in that ratio. There were exceptions, but as we know, it is the exceptions that prove the rule.

Thanks for the comments -- the Lotus and Cooper are from "High-Performance Cars 1962-1963", the angles are the original published ones. They do look much better nearly horizontal, rather than pointed skyward!

I try to not duplicate earlier posts unless I find a higher-resolution version, so Ibsen's index is essential! Sorry if I do repost something inadvertently.

There are still many more cutaways tucked away in the corners of books & magazines that have not made it onto this thread.

I believe you!

This reminds me of another, legendary, 'lost' cutaway once mentioned by a member. It was believed to be of the Fergusson Formula Junior (front drive, DKW engine)?

I'm crossing my fingers, that you may actually be the one to stumble across it sooner or later. :up:

Thanks for the comments -- the Lotus and Cooper are from "High-Performance Cars 1962-1963", the angles are the original published ones.

That is fairly common, I am not sure why a cutaway is seen as fair game when it comes to orientation, but portraits of people are not. However, page size and format does sometimes make it difficult to print a drawing the right way up, and there is no real problem with turning the book 90°, as long as it is pointed out to the reader that this should be done. Another common problem is printing across two pages and losing a chunk of the illustration in the gutter. With the Ferrari F2000 book I tried to get the illustrations printed as gate-folds, but this was probably an expense too far.

They do look much better nearly horizontal, rather than pointed skyward!


Sometimes when they are printed in an incorrect orientation, they look only slightly wrong, and you can't immediately put your finger on what the problem is!

Tony, I actually had the same thought, but checked and didn't find either in my modified files. Fall on either side, but not on these, so thanks for all the great new additions. Someone must be on vacations, or has recently been declared redundant (much more of a personal valuation than being "laid off" in my opinion ...). Whatever, keep it going.

These are usually surrounded by a few of those 'Piola' like non-'cutaway sketches'? little bits and pieces (modifications applied to car throughout the season). I have a stack of those little bits and pieces by D'Alessio, McLaren, Ferrari, Jordan etc, but I'm never really sure what to do with them.

In the meantime, could someone let me know what's going on at the outer ends of this gem - I can't work out how the 4 grouped pushrods get to actuate the valves.

(yes, please and I might have more luck with a different format; for some strange reason my Mac wouldn't swallow that even converted to jpg.)

onelung, how does that compare to the Rotax-s?

(i have a thing for boxers - the citroen/bmw end of the spectrum, so far)

thank you Tim,
i must admit while as the article says the arrangement is one of the oldest ("Contra" engine ... first installed in buses by Benz in 1889 and later on in passenger cars as well ...')
- 1946 was a surprise, as was the caption to the cutaway;
'THE functional details of the Jameson F-F engine are laid bare in this special "Flight" drawing by Max Millar. It has not been thought necessary to annotate the drawing as
the composition of the engine is so very simple, and the train of drives and geometry of motion can readilv be followed.'
however, on the next page ...

It is a very nice drawing, just a shame that the rocker-cover was not cut to show how the pushrods operated the valves. I wonder if there was a reason for that - although I can't see that it can have been seriously considered a worthwhile 'secret'! So near and yet so far... Thanks Tim for filling in the gaps. My GN has a similar cam-and-rocker system, just no pushrods in between them!

Tony,
Sorry, I did my normal vague reference, but was talking about all the recent rush of posts of some great new additions to this groups' collection. Didn't really note a change in your intensity here, which has always consisted of some wonderful contributions, whether visual or mental.
I tend to take blocks of time and will scan from the Cavara book, or the Haynes covers in bunches, but certainly can't keep going with the continuous submissions that are now coming. My deep appreciation for those who can.

Great! Thanks Tim - I should have delved a bit further into Flight Global which is, of course, where I scored the drawing.
Frank - thanks for the lead to the larger Lago drawing, and .. fnqvmuch: my boxer only has two gloves - it's a 2CV.
Werks - that system for the rear suspension is not at all uncommon for veteran era cars. It certainly makes a lot of work for the spring companies, though - and just imagine the weight of all that spring steel!

That's right.

I returned to the original article, and in the case of the Silver Ghost, the following specification is given:

Susupension: Front, dead forged axle and 10-leaf springs; rear, fully floating axle and 13-leaf springs. Transverse 11-leaf spring anchored to two diagonal chassis members and ends of leaf springs.

Apparently, it was great on the 'trial courses' of 1907.

I especially like the work of 2 of the illustrators that we see regularly work of. One of them is of course our very own and the Master of this Art, Tony Mathews and the other is Bruno Betti.
We know a fair bit about Tony but I was just wondering if anybody knows what Bruno is up to these days. Where does he live ? Is he still working ?
Thanks.
