After having finished my GPdG-proxy-racer, I will continue with a car, that I had begun just before: the 1961 Ferguson P99. This car should complete my cloverleaf “early sixties formula cars with front steering”, consisting of Porsche 787, Ferrari 156 and the Lotus 18/21, that I had shown before. I started with a Betta&Classic shell, a SCX steering frontaxle, a small motor and a bit of soldering sheet. Now a bit detailing for the front axle: painted now, will get thicker springs! and the same started at the rear: The track (? -> the width of the axles) has to be smaller, I will start at the front axle. Progress will be shown.

Very nice Taffy. But when are you adding the 4 wheel drive? ;D

Very nicely done and I especially like the suspension additions. And of course the question of 2 or 4 wheel drive always looms with these cars doesn't it? Howard

One of the problems attached to being interested in many things is that posts are read, ideas are formed, and well, we will see.
It is all the fault of Howard, those tugboats have gone to his head.
4WD. Oh dear.
I have an MRRC chassis, I wonder if it will fit the P99? It did of course fit the Novi, was it a similar size?
A new guide would be needed of course. Yes, the original would do in cut down form, but after that?...
Time for a little thought...
Peter.

I claim Benzine for all my bad ideas!!!! Too many fumes for too many years. That is my excuse for causing trouble!!

Hmmm Peter - it'd be interesting wouldn't it. i've been thinking it through for about a year now....
I was thinking you'd really need to have 3 diff's in there. One on each axle and of course a central one to split the torque front and rear!
If you mount a diff such that the motor drives into one end (where one of the axles would normally be) and then run the rear axle from the second axle (in line as it were) and then use the main drive wheel to run drive to the front axle (stepping sideways around the motor) what happens? I just can't work it out but have some kind of gut feeling that it'd be an interesting experiment....
The problem with scale diff's is that they're not LSD's and that is what apparently you need and this car had mounted centrally. Any ideas how one could scale that?
I have that lovely 4wd book by Donington Press and it details quite a lot about the Ferguson.
I've found the diff parts - now I just need to get round to starting. I guess i'm using the Beardog_Rowland Lotus 63 as a sort of test bed for normal 4wd before launching on this one.
Looking forward to see what you do.
Andi

Andi, why have diffs? If power is limited, fair enough and of course tyre wear would suffer, but no more than on the average slot car. Thus no need for a limited slip either. The only time I have seen a slot car 'wound up' due to lack of a diff. was with one fitted with a magnet and sticky tyres combined. Fine in a straight line, but useless on even large radius bends.
Peter.

Peter - i'm shocked!!!!!!!!!!!!!! WHY? ? Surely you of all people would understand the 'why' have diffs question...... Wasn't it you posting that same picture with one of parallel link suspension at the end of my Vanwall thread and talking about the simple pleasures of engineering? If you don't understand i'm certainly not going to explain..... A very hurt Andi, signing off.

Taffy, I'm afraid I've taken the thread off topic. Apologies.
I've started a new thread to cover what might be described as 'prototypical chassis features'.
Peter.

No problem, Peter!
I have thought about a 4wd for this Ferguson, but I have given up the idea, because I wanted to use the SCX-steering axle, that I had in stock, to complete my cloverleaf of cars with steering axles.
Interesting discussion!

Sorry, it took a while, until I could find any time to continue with the Ferguson. But this weekend gave me time to progress. I had to make the front axle smaller, so I shortened the stub in both wheels and made new axles and bearings out of brass tube: Then I finished the rear axle. Unfortunately, left and right side look a little bit different, but with both sides coloured, its not to be seen so much… I continued with decaling and decided to make the #26, which was the car, that run in the British GP in Aintree in 1961, driven by Jack Fairman and later by Sir Stirling Moss. The roundels are a bit too small: Dashboard, shifter knob, exhaust, hood closers…. Chassis an body put together, in Germany we call it “the wedding” The difference of colours comes from photographing with and without flash. The darker colour is near to the real one. Driver is painted: …will be continued…. VBR, Taffy

This is excellent Taffy, I look forward to your next post.
Whilst the 1960's is not my period, I continue to be spellbound by the high quality of work, with the normal high quality of finish which most models achieve.
Apologies however, I still think Danny's 1906 Darracq will set an even higher standard.....

Peter, that is no problem. I think, if anyone says "scratchbuilding" to my childish efforts, how should we call Danny´s work? I think, "the art of scratchbuilding" would be the right designation...
Bst regards, Taffy

Taffy,
The Ferguson seems to be popular model for some of the more talented builders (which explains why I've never tried to build this car!).
The shifter on your car is such a fine detail. Call me crazy, but I really appreciate those small touches that you put into your builds.
VBR,

The P99 is an interesting build. I did one several years ago based on a Classic shell with a front mounted motor: The very narrow bit of body between the RH cockpit and the suspension cut out did not survive the trip back from England and, rather than patch it, I have decided to rebuild using a Dave Jones shell although it a ways down the build list!
