McLaren M19A, Denny Hulme, 1972 South African GP. MFH, 1/12

[pg265]

Good morning,
 
The Ferrari 312B on break, I’ve decided to start this beautiful 1972 McLaren M19A.
I love the car, but would have preferred an earlier version with McLaren colors: the wonderful Papaya Orange.
The 1972 South African Grand Prix winner, in the Yardley colours, will be in the hands of Denny Hulme: The Bear!

 

 

 

The kit is very nice and rather well studied, finely molded and made parts, both for resin and for White Metal.
The decals are sumptuous.
 
Start with the first assemblies on the engine: A DFV!

 

 

 

 

 

I made small blanking plates for the holes of the lower engine not used on this config.
They are made of very thin aluminum foil, drilled and fixed by machined BTR.
Of course, all this will be virtually invisible… 
The water plate is also installed and fixed in the same way

 

 

 

Many holes are made for subsequent assemblies.
A part of the accessories is installed on the left of the block.
Some parts are treated with browning.
The clutch is only installed for fun.

 

 

 

 

In order to ensure good alignments, the box is tested, its inking points on the block adjusted: Not too bad.

 

 

 

Well, it’s not all that, but I worked a little on housings/crankcase of all kinds.
Those from the waterfall at the front of the block and the friends who hide the camshafts.
 
First a few holes, of different diameters, very light sanding and polishing on the Ford logo and masking with  gum for artist.
Then a little prep.

 

 

 

 

 

 

The right side is equipped with its accessories.

 

The water pipe, in 2 parts, is welded and polished.

 

 

 

One of the fuel pumps (attached to the block and mechanically driven by the block) is modified, painted and equipped with a Banjo fitting and an angled AN fitting… both made of machined aluminum.

 

 

 

The transition of different shades to oil will give a little life to all this little world very soon.
 
I must admit that the assembly of this model requires a certain habit/ experience of kits of this type.
The plan shows pieces whose fixing points/pawns are missing from the physical parts. Many modifications and tricks must be used to achieve the “desired” result.
A good knowledge of the engine as well as a good documentation are also necessary to realize connections,
missing connections/hoses and other wiring.
For example, the pump I just installed is connected to the electrical pumps in the bulkhead and the tank, but not to the filter and the injection pump, both of which are present and detailed…
This is, I think, the first model from MFH that gives me these small inconveniences. 
But hey, we’re not gonna complain, right?
The kit is sublime, like this car that I particularly like!
If only an M7A showed the tip of their muzzle…

So, let’s close this parenthesis…
The Cosworth block is progressing.
I have made some details and quite a few changes.
The vast majority of cables and hoses are not those provided by MFH.
The entire power circuit is reproduced.
The assembly of the admission ramps is not so simple because of the high room through which the trumpets pass.
It must:
- pass all the trumpets,
- stick them on the guillotine ramp (taking care to properly align the injector openings)
- turn the assembly and center the upper piece on the trumpets and stick it inside the capillary openings on the trumpets… without burrs and other traces of cyano.
A very fluid glue was used for this.

 

 

 

 

 

 

 

 

Pretty good, even if I’m not more satisfied than that…
The DFV engine of the Lotus 49 at the same scale is really of another quality, at all levels.

For fun and because between the two my heart swings!

 

I started working on the hull.
It is a composite assembly of resin and White Metal, mainly screwed.
It’s more work than it seems.

 

 

 

It is therefore necessary to drill all the elements according to different diameters according to which the part must be threaded or only to let pass the screw... and therefore tap in 1.4mm mainly in metal and/ or resin.
The «bathtub» will also be welded once its parts polished and riveted.
We are still far from it!

I decided to bring the engine for an exhibition in Niort.
So it took, for fun and a better presentation, to finish it a little better.
- Front plate installation,
- Painting and treatment of the steering wheel/clutch assembly,
- Installation of yellow "plugs" on oil outlets.

 

 

 

 

 

 

The dark parts are treated with  Blaken'it, rubbed and passed in oil.
the «golden» part is painted with Humbrol Metal Cote, little pigmented to obtain a certain transparency of treated metal.
Two/three details and transplants, and zou!
It’s clean, it’s not too bad.
The set will go back into the rabiot box when assembling the gearbox.

In his box for transport.

 

 

More very soon,
Pascal

As always a superbly neat and clean work, will be a pleasure to follow!

[Vesa Jussila]

Extremely clean work. I am waiting your work with chassis. Looks really promising. 

[keefr22]

Another Pascal masterpiece in the making - looking forward to watching this one progress, that engine looks just gorgeous to me! And working on such nice metal pieces in this scale must be similar to building a real motor!

 

Great start to a model of a beautiful car! 

 

Keith

[Malc2]

This should be good.

[heloman1]

Exquisite! The engine alone makes a good model, the level of detail in the castings and moulded parts is unbelievable. I'll follow your build with great interest.

Hi,

 

Thanks a lot for all your kind comments and the warm welcome for this new build!

 

GEARBOX!

It is not spectacular in the photo, far from it, but it is the whole with the addition of what will be connected on or assembled around.

 

 

I also needed brass bolts/washers (ø1.5 and 2mm) for the Hewland box.
Of course… nothing!
So I machined them.
The picture is… Bad (!) to say the least, but I will try to make better ones in the situation on the box.

 

 

As I was in the DIY mood, I decided to redo the pump at the rear end of the gearbox.
It is turned into a remnant of aluminum log, then pierced.
It is 4x4mm.

 

 

 

 

 

Test fit of the machined brass parts on the box.
I took the opportunity to machine straight A/N fittings: to improve, but not too bad.

 

 

In order to be able to assemble and paint most of this set, a lot of preparation work, drilling, tapping… is necessary.
Once satisfied, the parts are primed.

 

 

Then painted in various shades of black.

 

 

The Hewland casings are given several shades of oil and the A/N fittings are partially painted.

 

 

 

 

I mounted a disc and made a tool to be able to install it on the lathe to finalize its appearance.
I’m starting to have a few tools as I make one for each model.
 
Other parts such as calipers and starter elements are treated with Black'it, rinsed and brushed.

Always many tests, adjustments, drilling…
Blank mounting to validate sub-assemblies.

 

 

I made the identification plate of the box in a very thin sheet of aluminum, Speed Tape in fact.
It’s a little more realistic than painting in aluminum the relief of the box end part.

 

 

 

 

I apologize in advance for the quality of the photos that follow: it is late!
 
The assembly of the gearbox continues.
It is a set that seems simple, but is not because of all the elements of the rear axle, brakes, transmission.
 
As I said before, preparing the elements takes time.
To illustrate my point, here is the image of a shock absorber being prepared next to a “raw”.

 

 

The first photo also shows the records… But, by mutual agreement with myself, it was decided to bring a little more detail.
So I drilled the internal flanges to install Allen hardware.

 

 

As long as one is engaged in the detailing, the calipers are equipped with their bleeders and fittings for the brake fluid lines.

 

 

All suspension elements, springs.. , were primed and painted in satin black.
The stabilizer bar and its rods are brushed and then chemically browned.
Everything is finally assembled.

 

 

 

 

It remains to refine some details with oils as usual.
The battery tray (photo-cut part to fold) is installed temporarily.

The exhausts are done.
A small weld is added as well as the tab that holds the 4 in 1 on the collector.
The outlet is only temporarily installed because it must be aligned with the support that will be installed on the box.

 

 

The printed parts are… awesomely stunning! The spectacular and splendid exits of the 256F1 had already left me speechless!
 
Here are the elements waiting for some black (satin, matte or a mix of the 2).

 

 

The exhausts are finished, the welds added.
The radiators are much better than other models: White metal for the filling and photo-etched grille.
The result is very satisfactory and should be quite realistic once the satin black is applied.
 
For more realism, I represented the welds on the oil tank.

Superb update Pascal - some really marvellous modelling (& micro-engineering!) going on here!

 

Lovely stuff!

Hi Pascal, I appreciate that English my not be your first language,  but you appear to have got the words very satisfactory and totally stunning mixed up 😁😅.  Thanks for sharing - Andy 

[pg265]

Good evening,
 
Thanks so much  for your comments.  
 
Progress on the gearbox is laborious but rewarding: we are starting to see the end of it!
 
The battery, its wiring and the starter are done. The gearbox oil circuit completed.
 

 

 
The oil radiators are assembled and equipped with the rear light.
 

 
I made a small part for the back of the rear light. It will later be equipped with its wiring.
 

 
The oil tank is installed, the recuperator is temporarily put in place: photo-etched collars to be formed should soon fix it and the clamps which hold the hose are on standby.
 

 
I made a little “oil” for the hose and the can got a bit of it.
 
The exhausts are painted.
 

 

 
More soon.
 
Pascal

[Vesa Jussila]

Masterpiece!

[pg265]

Good evening,
 
Thanks a lot!

 

The can straps are done, the Serflex in place and a Gulf sticker brightens up the oil tank.
 

 
I drilled a hole in the axis of the cap and slipped a little “oil” in for more consistency: it comes from the top, flows down the side of the can to the bottom.
 
A terminal, screws and cable: the rear light is ready to be connected.
 

 

Time to take care of the interior.
The first step is to start giving a little shine before riveting the aluminum sheets.

 

 

 
More soon.
 
Pascal

[keefr22]

Absolutely stunning modelling Pascal, superbly realistic work!

[Miko_Skye]

My goodness, this is next level amazing. Cant wait to see more. Thank you for sharing.

[pg265]

Good evening,
 
Thank you very much Gentlemen!
 
The “bathtub” is:
- Polished,
- riveted,
- assembled (welded)
 

 

 
The gearbox control linkage has been modified: the White Metal part is cut and replaced by a blued brass one.
The selector is detailed with the addition of welds, a bolt accompanied by its nut and washers.
It’s more coherent, pretty… and I like it!
 
The original knob is very good.
I told myself that rather than painting it in wood tones, I would make one… in wood.
I cut a “cube” from a piece given to me by a friend (stratospheric model maker!!), of a species that I don’t remember.
I then simply turned it and varnished it.
This type of wood is very hard, but very beautiful.
 

 
Not much image today (Las Vegas this morning, flight this afternoon), but work and lots of preparation and modifications which should quickly make progress in the cockpit.
Besides, since I like simplicity and think of everything…
I decided to drill the left side of the bathtub.
This is of course the thickest part, for a large diameter hole... with all my rivets next to it.
It was necessary to take out different diameters of drills and finish with the step drill.
 

 
Here is some of the prepared pieces.
 

 

 
I reproduced the appearance of the anti-slip engraving on the pedals; for what we will see… but it’s there!
 

 
And here is some of the painted pieces waiting for all their details.
 

 

 
That's it that's all.
 
Pascal

[keefr22]

It all looks fantastic Pascal, but that gear knob is something else - stunning!!

 

Keith

[Toftdale]

A totally inspiring build, thanks again for sharing - Andy 

[Malc2]

Looking great!

[pg265]

Good evening,

 

Thank you!

 

Work on the interior continues, particularly on the dashboard.
I started from the principle that, although pretty, it was possible to add 2 or 3 details.
 
Some modifications are made to the pressure gauges (pressure connections, specific cable for temperatures) the starter push button is turned, the switches and other indicator lights connected, the support for the small panel created...
 
The rev counter is on stand-by: the needles must be painted.
The glasses will finalize the assembly of the meters.

 

 

 

 

It's progressing slowly, but it's moving forward.

It might be slow Pascal, but it's extremely nice progress!

[PROPELLER]

And as usual... mind blowing!

You might want to check the orientation of the rev counter with photos. Most were aligned so that max revs were at the 12 o'clock position (easier to see for the driver). The red needle is the "telltale" that is mechanically driven by the rev counter needle, so should also be at max revs (or more if you're modelling a lunched engine!). These telltales were re-settable using a button on the back of the instrument.

[pg265]

Good evening,

 

Thank you very much guys!!

 

The Rev was installed straight and it was the same in the M23.

I was surprised as I also thought it was oriented.

 

Here is some progress again, still in the cabin.

 

Sewing workshop today!

The fabric straps provided in the kit went into the cabinet box.

New ones, made of lead sheet, are primed, painted, “sewn” and partly installed.

 

 

 

 

A few oils will finish the job.

 

 

The dashboard is completed and put in place.

 

 

 

 

The fire extinguisher bottle is the next step: need to paint it and turn a part to make it a little better and connect the pull cable to it.
 

More soon.

Pascal

[Jo NZ]

Good stuff! I see that the rev counter is installed straight, and conveniently max revs are at 12 o'clock 🙃.

 

The belts look very realistic too, great curves.

[keefr22]

More super progress Pascal, have to agree that the belts look very realistic - you did a great job with the sewing needles....!!

 

I really like the wiring you've done behind the instrument panel too (actually I really like everything you've done so far!)
