I thought 3L stood for 3 litre which was the F1 engine size introduced at the start of the 1966 season to replace the previous 1.5 litre formula1. The Lotus 25 (the first monocoque chassis F1), introduced in 1962 and 33 in 1964, were the last two 1.5L cars from lotus. Both were highly successful winning multiple GPs and the world championship for Jim Clark. They are very small and slim. The 3L cars were immediately much bigger so make better slot cars. Because the Lotus 43 (BRM H16 motor) was late, Lotus ran a 33 in the early part of the 66 season with a 2L version of the Coventry Climax engine, so it just scrapes in as a 3L. This was hopelessly outgunned, even with Jim Clark driving it and looked ugly with the bigger pannier fuel tanks which were needed in 1966.
Lotus 33 from Dave Jones Lotus 25 shell
Yesterday I began to think about building a late '60's F1 from the so called 3L period.
The only shell I had that would be appropriate was a Dave Jones Lotus 25, bought from him back in 2011 at Early Birds.
I have never really studied this period of cars so it took me a little research to understand the differences.
I had a hunt around my box and found much of what I needed:
Tyres, gears, motor, wheels, axles, body shell, driver body.
I've cut a brass sheet for a simple chassis but i'm worried that the motor will be too high in the cockpit if I sit it on top...... the body is really very low!

You've taken on quite a modification to Dave's original shell.
His shell represents the car when it was launched in 1962 and was at its most sleek, the gearbox cowling was discarded by Lotus after the gearbox overheated during the first couple of grands prix. The Lotus 33 that Lotus ran at times in 1966 and 1967 with stretched Coventry-Climax and BRM engines was the result of loads of modifications over the six years of racing it in 25, 25B and 33 specification.

My 1962 Lotus 25 built using Dave Jones original shell.

My 1965 Lotus 33 using a modified vintage Monogram bodyshell. The 1965 Lotus 33 looked pretty much the same as the 1966/67 version other than the wider tyres during the 3-litre formula.
I don't know what photos you are working from but the more you look at the two cars, the more subtle differences you will notice (I don't have to tell a talented model-maker like you that).
The nose is pencil slim on the original 25 but the nose deepened and the radiator intake was larger over the years, the windscreen was revised with the aero flip-up to the bodywork and the opening in the screen (Clark was always bothered by his head being buffeted by the wind and Chapman did as much as he could to make him comfortable), the rear suspension varied over the years from 1964 to 66 but the immediately apparent difference is the positioning of the rear radius arms into the side of the chassis and obviously the rear engine cover varied a lot which I can see you are already working on. Lotus used Firestone tyres instead of Dunlops during 66 and 67.
I hope you don't mind me sticking my nose in....

Andi,
I'm sure you've already found a score or more pictures of the Lotus 33s from 1966 and early 1967, but I thought I'd post a couple of photos of the two Team Lotus cars at Monaco in 1967:
![Lotus-33s-at-Monaco-1967.jpg]()
Clark drove #12 powered by a 2L Coventry Climax V8. Jim was on the 3rd row at the start of the race, and set the fastest race lap time, but his Lotus retired on lap 42 with suspension problems. Car #14 was Graham Hill's Lotus and was powered by a BRM 2.1L V8. Hlll started the race on the 4th row with Dan Gurney. With various retirements, including Bandini's terrible and fatal accident, Hill eventually finished second to Denny Hulme in the Brabham Repco BT20.
5 or 6 years ago, I modified a vintage Monogram Lotus 33 shell to replicate Hill's Monaco car by reducing the height of the side sills and extending the cowling behind the injection trumpets. Unfortunately my Lotus had a bad habit of shedding parts at an alarming rate during the proxy race series in which it was entered. Another poster on this forum can attest to its fragility (which was not intended to duplicate the original car!) My Lotus moved from race host to race host accompanied by a small bag of plastic, resin and metal parts; the number of shed parts increasing from race to race. It didn't take much time or effort to kit bash the car upon its return from series, as a fair number of the small pieces were already detached by that point.

The shell that remains in one of my spare parts boxes probably doesn't look a whole lot different from the model at its final race (with a banged up chassis underneath it of course) Although as I remember the reporting, the wheels may have been the only items that did not fall off my Lotus during the series.

Enough history and personal nostalgia from me.
Wishing you great success with your build. I am confident that your Lotus 33 will be both attractive AND sturdy.
Best regards,
Mark

The build has moved on and after numerous rounds of filler and sanding we have got some top coat on.
I tried a technique whereby I masked the steip and sprayed the green first. The thinking was that I wanted a deffinate yellow strip rather than using decals and I wanted both the yellow and green on the white undercoat.
it has more or less worked with a tiny bit of white edge showing in one place.
The engine and exhaust detail is from a Scalextric Lotus 49 which I had recently carved up to do one of my Policar conversions.

The chassis has been painted black so that it fades into the shadow under the car.

Progress is slow but constant, I suppose in reality I only began this about 3 weeks ago but it seems like ages....
Once the shell was painted I began decalling and immediately realsied that the roundels were not strong enoug white to work on top of the dark background. This was annoying as it set me back and meant I had to rethink on the hoof. In hindsight I should have reverted to another roundel with a stronger white but I decided to spray the roundels instead.
Cutting perfect circles and then expecting them to form a perfect round when the masking was removed was ambitious. Too ambitious as it turned out.
Anyway to cut the story short I trimmed a bit, sanded lightly and polished out some of the defects and from about 1m away it looks fine but of course shows up in the close ups!!
No time to start agin so on with the decals and tamiya top coat and the thing is starting to look like a car.
Clark (Immense Miniatures of course), is in the car and the windscreen is on. A host of tiny details to go but i'm confident I will make the start line in early December.
