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.



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 hallucinating finesse and precision! 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.



More soon.

Pascal.

Very nice looking engine

Very nice looking little engine and drivetrain

[pg265]

Good evening,

Thank you 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

[Johnj]

That engine is sublime. You could be forgiven for thinking it was the real thimg
True modelers kits

[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

[Twokidsnosleep]

Holy shoot this is excellent
What grade of engine oil does this need??
Certainly will follow along

[pg265]

Good evening,

Thank you very much!

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

[BigWall]

That's a lot! The knob is amazing! How was Vegas?

[pg265]

Hi,

Thanks a lot Joe!
Vegas was… on TV!
The GP was pretty cool.

Pascal

[Twokidsnosleep]

Oh I love this all so much
The real wood shifter is the icing on the cake so to speak
Just lovely modelling here, lovely

[BigWall]

Hi,

Thanks a lot Joe!
Vegas was… on TV!
The GP was pretty cool.

Pascal

Yes! I watched it. I hope you had a good time!

[pg265]

Good evening,

Thank you!
Yep, I enjoyed the GP. That was a great race.

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.

Pascal

[cor]

Its very nice work. The last pic of the guages look like the real thing

[pg265]

Good evening,

Thank you!

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: you need to paint it and turn a part to make it a little better and connect the pull cable to it.

More soon.

Pascal

[digger303]

Excellent.

[pg265]

Good evening,

Thank you so much!

As usual, a lot of research work, preparation/modification and assembly.
The front of the chassis is assembled, its photo-etched upper part is drilled, installed and riveted.
Everything is masked for the painting phases.





The upper suspension arms made up of 4 parts are assembled by welding: it's stronger and more fun.
They are drilled and tapped to receive 1.4x3 screws.

The majority of parts intended for the front axle are awaiting the primer coat…



...with which they are now adorned.

The fire extinguisher was painted and varnished yesterday and received its decal this morning: Classic chronology!

However, in my opinion, details were lacking; I tweaked 2-3 things.

I turned the tip and a small gauge then assembled them.





The Mano is 2.4mm with a small shoulder of 1/10th to center and give a little depth to the dial.

Serflexs are added, equipped with cruciform screws.
The decal is deliberately placed forward (as if the cylinder was turned), and the Serflex slightly offset to give a little dynamism.





Of course, you can't see much once everything is installed, but it's there and it was fun to make!







The fire extinguisher handle cable is held using a small photo-etched Top Studio part.

The shock absorbers are assembled and decorated.



The previously prepared parts, painted varnished... allowed the front train to progress.
The whole thing is riveted where it seems necessary.









The pedal assembly is installed and the accelerator pedal is equipped with its control for the cable (clevis, nut, bolt, washers.)



Let’s go to the lathe for the discs and hubs.
They are equipped with their spindles and installed on their hub carrier. The calipers are temporarily positioned, awaiting bleeding and fittings for the braided brake fluid lines.





More soon.

Pascal.

[cor]

That is looking very nice. Good work on the extra detailing.

[digger303]

What he said.

[pg265]

Good evening everyone,

Thank you so much!

The build continues peacefully, slowly, much more than I would like...

The two front half axles are almost finished, the brake connections are installed and the calipers are just waiting for their bleeding.



The steering bellows will be painted later, the discs patinated to follow.

The front rims are finished, balanced, center polished.
I preferred machined valves to those from the kit.



One of the tires is mounted on the other rim. It is lightly sanded and will be detailed soon.



And here is the wheel shown on its half train.



I was also finally able to complete the rear calipers by fitting them with the missing bleeds.

The engine should cool much better: The braided hoses connect the tank to the oil radiators.
The whole thing will of course be connected to the engine a bit later.











More soon.

Pascal

[DRUMS01]

So when are we going to hear it run? (smile)

As I said before, just because there are detail sets available and MFH makes a museum quality model, you still have to have the modeling chops to properly build it and you are doing just that. Wonderful modeling skills, keep it up!

[pg265]

Good evening,

It’s time to get back to work on the M19.
Thanks a lot for all kind comments and for being so patient!

The body parts have been prepared for the first phase of painting: the primer.

The rear hull bulkhead was riveted and masked.



The various parts of the rear wing
If they are also prepared, the main horizontal plane is drilled to receive the rivets.



The front fin locations are drilled, the muzzle support bar on the frame frame is made of a brass round.
It is turned to drill the ends at 0.8 in order to make it solidly attached to the fins.



The lower part of the anchor points and air-vents are fixed.



As usual, a lot of work in preparation of the White Metal parts to get what I want.

Some job needed on the radiator frame: drilling, alignment, filing...
Followed by the primer on the frame and the rear bulkhead.





The radiator was fitted with its pipes which had been prepared at the same time as the armature parts.
So we get the iron, flux and solder.






Checking the appearance of the previously glued scoops, I changed my mind about the nose attachment axis.
Out the brass piece. I installed the originally intended steel part (which I could not find...) and modified the fins for a solid, horizontal fixation.





Necessary job on the hull to adjust the hatch to its opening which was too small.
Easier said than done to keep a straight opening... but the Dymo tape helped me.





After the primer it’s Paint time.
The white has sprayed on the partition.
More a veil than a full coverage on the sides, but it is not worse for the layer that follows.



Papaya Orange



There is a quick touch-up to do, no need for masking.

The radiator frame is painted black.



I had to make a small repair on the lip of the air inlet: a little primer validates the good condition of it.
Same thing for the scoops.





More soon.

Pascal

[pg265]

Good evening,

The radiator frame is made.







Test fit on the front part.





The white touch-up is done on the rear bulkhead, all that remains is to add the white rivets (not installed to facilitate masking) and varnish.



All the body parts, the horizontal planes of the rear wing, the scoop, the “whiskers”… have been prepared.
Long-term work, to say the least!
And primer.





The primer revealed some very limited surface defects that will need to be repaired.

The vertical fins of the two fins and the rear fin partitions have been prepared for blank assembly and will be primed later.
The fit check of this assembly is complicated, acrobatic and requires a lot of attention for the positioning and drilling of the upper plane.
But it is better to have checked everything before the final assembly of the painted and varnished parts.

Pascal

[pg265]

Good evening,


A small session of sanding and refinishing certain elements, re-priming, then painting.
White is White!









Masking to follow before the Papaya Orange and a saving for the numbered circles.

The rear partition, now varnished, we can start working on it.



This is only the beginning of the (light) stage of highlighting this partition stuck to the engine.

More soon.

Pascal

[pg265]

Good evening,


Work continues on the rear bulkhead.
A little satin black and some aluminum fixings.



This is also the start of the detailing of the fuel pump with coloring: polishing wax for the brass of the upper part, chemical burnisher for the lower part.
The part had been prepared and drilled yesterday.
She's waiting for her Banjo fittings.



Here it is temporarily mounted on the bulkhead.



The radiator and its support also benefit from some additional details and some oil nuances.



I made some masks for the roundels and the body sides.
I plan to mix the rivets on the hull according to the places to be treated.

More soon.

Pascal

[pg265]

Hi,

The sides are masked before receiving the McLaren color.



They should now receive the line of rivets located at the rear.
Once the tails of the rivets were cut, I decided to cover this area with a thin aluminum sheet for a better finish.



The aluminum is quickly primed.
McLaren Orange is then sprayed on.





Pascal

[digger303]

Lovely colour.

[Twokidsnosleep]

Glad to see this back on the bench

[pg265]

Good evening,

Thank you very much!

The thermoformed rhodoid windshield is cut.
It is then installed (forced) onto the hull to be drilled.
Pins allow it to be held in place for final adjustments.



The different parts of the rollbar are prepared, presented on the hull and then welded.







The electric pump is detailed with a banjo fitting equipped with its washers, as well as an A/N fitting.





Some details and appearance/cosmetic defects have been taken up on the hull which should soon receive a new coat of white.

Pascal

My favourite era of F1, I was a very young lad at the time, good to see you building another F1 car
