1/12 MFH Ferrari GTO 250 - Finished

Recommended Posts

I have a major distraction from large scale planes going on, being this Ferrari GTO 250 from Model Factory Hiro. I think it does qualify as large scale, and the real thing costs more than a small aeroplane, with the last one going for around US $ 48 million. To my mind it is one of the most shapely and attractive cars ever made. There are not many WIPs of these examples, so I thought I'd give it a go. The kits themselves are horrendously expensive, but are incredibly well detailed. I also have a classic Pocher 1/8 Alfa Romeo in its box waiting to be built, but the MFH kit wins hands down in terms of accuracy and fit. I have got this to completion of the engine, but won't be taking it much further at this stage as we are relocating from Australia back to New Zealand shortly. 

 

The model comprises of the major body parts being formed in white resin, with the bulk of detail parts being in finely cast white metal. These are complemented by two large and one small etched stainless frets and a large number of very nice plated metal parts, wires, tubes etc. The spare wheel is made up from cast parts, whereas the main wheels all require building up with stainless spokes, turned hub parts and plated rims. The detail is nothing but stunning, although I am still not sure that I am Zen enough for the experience of building the wheels. I'll use the rest of the kit as practice.

 

My early lessons in my work on this so far are that the kit instructions must be studied extremely carefully and on any one part you need to be looking several stages ahead to check for any fit details. Unfortunately the instructions are not quite as clear as they could be, but that is more a reflection of the sheer complexity of the kit. The many hundreds of tiny white metal parts all need cleaning up and often require relatively minor work to fit perfectly as originally designed. Because of the amount of detail included, there is absolutely no wriggle room in terms of fitting all of the various assemblies together. If they do not fit perfectly, then there will be trouble later!

 

But, before even starting, delving into the big red box revealed all of the white metal parts wrapped in layers of plastic wrap in one bundle spread across the bottom of the box. Unfortunately I didn't photograph it - it had the appearance of a mass of metal cobwebs! What I did photograph is the end result of many evenings spent sorting the parts into small bags labelled with the relevant instruction step. None of the parts are numbered, and some were a real mystery until the process of elimination identified their place in the scheme of things. There are still a couple of pieces that I have yet to identify - and only one small missing part which was quickly set right by MFH. The only aftermarket I have got are seat belts, scale pipe clamps and some tiny pipe fittings for some of the oil pipes.

I had decided to build this as my representation of Chassis # 3757, which has belonged to Nick Mason of Pink Floyd fame since the late 70s. This choice is mainly because it is surely the most photographed example. I even have an entire book, almost all of which is devoted to this particular car. Plus I am a Pink Floyd fan. The kit includes markings for "White 22", but the model is a curious mix of the car as raced in 1962 and some later changes made to her. I will model the car as she appeared about the turn of this century. it will include the three cooling vents behind the front wheels and an oil cooler above the rear axle, but will be before the two rows of cooling slots were cut into the bonnet. This particular car also had the bolt on rear spoiler, as originally fitted, replaced by the later faired in version, so that also must be changed. 

 

One of the small number of inaccuracies in the kit which I have found are the cooling intakes below the nose. They are modelled too far back from the front and, as a consequence, are formed too shallow so as to avoid fouling the radiator as they sit directly beneath this. In fact they are located very close to the nose and direct air to the radiator.

 

So the first job was to take a wonderfully molded resin body and cut into it. The new intakes were formed from plastic card and then glued into a rectangle cutout made in the resin body. I made a template for the cutouts in paper as the shape was not a simple one to cut directly into plastic sheet. the gray area is where i hadn't managed to superglue the rectangular insert in perfect alignment with the body and had to use filler to smooth the join. GT 3757 has an L beam across the rear of this panel, presumably as a stiffener. I replicated this with a piece of brass L section. The cooling intakes are still not quite as close to the front of the bodywork as they are supposed to be, but to bring them any closer would have required a total rebuild of the nose, due to the way in which the piece has been formed. This I was not prepared to do as I would surely ruin a perfectly shaped nose.

The other body changes were smoothing in the rear spoiler with the surrounding body work, cutting an extra cooling slot behind each of the front wheels, rounding off the corners of the remaining cooling slots and extending the spar wheel storage shelf to the rear of the body shell. The cooling slots , which had squared off corners as provided, were rounded off using superglue gel, but will no doubt require further work when eventually primed. I think these also had panels behind them as "gills" which will need forming from plastic card.

I will post the work on the engine later, and then there will be a break until the model reappears across the Tasman.

I need this kit,  I just finished the Fujimi kit of this car last night.

 

My all time fav car,  I just don't have the 30+ million to buy one.

My favorite Ferrari of all time.

 

Nick Mason, the drummer from Pink Floyd, has one.

 

I'll be following this one closely!

Cool. I can watch you to see what to do with my 1/8 Porsche RSR Carerra

 

Not sure I'll be of too much help there. It would be great to see a large scale Porsche WIP though! Cars always seem much trickier to get looking right IMHO, but definitely the larger the better.

That Fujimi kit appears to be quite popular. Not quite the heft of the MFH one though. I'll do my best to do it justice.

The heart of this car is the 3l V12 which dates back to the end of the Second World War. Like the body, it's a very attractive piece of machinery. The scale version from MFH certainly does the engine justice, but what a lot of work! The kit includes all of the internals: crankshaft, bearings, connecting rods, pistons, timing gears, camshafts, valves, flywheel. All pinned together so that they move in unison. Dozens of tiny holes have to be drilled in almost as tiny white metal pieces and, provided you are absolutely fastidious in placing the superglue, it all hopefully moves with a satisfying smoothness. And then gets closed up never to be seen again. 

 

I spent weeks working on the engine block in the evenings and did manage to get the pistons to do their thing. The thought of a similar amount of work on the heads was too much, however, so all the little valves remained in the box. The few WIPs on line all are concentrated on the engine so I didn't take many photos of the building process. All of the facing edges needed smoothing off and holes needed to be drilled for all of the pins on the parts. Much time was spent temporarily assembling different sections of the engine to ensure everything fitted, taking them apart, tweaking the parts and reassembling. 

 

I used a brass brush in the Proxxon to clean up the pieces, except for the exterior surfaces of the engine block and gear box which were finished off with wire wool. The only painted parts are those finished in either black (Humbrol) or brass (Mr Color). All of the parts, with the exception of the hose clamps, are from the kit. The first two photos show the block internals.

The instructions direct the six Weber carburettors to be assembled and then placed as complete units on top of the engine between the cam covers. The risk of having the beautiful turned trumpets out of alignment when doing this is very high and the space to squeeze the bodies between the cam covers is very limited. I built them up in layers from the bases to the bodies and then the trumpets in place on the engine. I used dabs of white glue to position each in place and hold it once I was happy. Superglue was then applied using a needle to fix each part in place.

 

One inaccuracy noted was the kit providing venturi pipes for placing within the trumpets which are almost the height of the trumpets themselves. I used fine brass tubing cut to 3mm lengths. The tiny etched valves slip over these to nestle at the bottom of the trumpets, aligned in one of two different directions depending on which side the trumpet is on. Yay for white glue heavily diluted and applied with a 000 brush.

The second photo above also shows a problem encountered with the accelerator linkage to the carburettors. i had neglected to trial fit the series of rods and bell cranks which form the linkage and simply fixed them in place as I progressed from the left cam cover. The final rod ended up being misaligned. The proper fix is to trim the rod running across the rear of the cam covers by 1.5 - 2mm, but it was all permanently in place by then. I cut the misaligned rod from its ball joint and reset it. The fine tension spring required prestretching so as not to over stress the resulting glued bond.

 

The next photo shows one other minor curious error in the kit. MFH provide a very nice mechanical fuel pump which attaches to the bottom left hand side of the timing cover. In fact this was never fitted, but two electric fuel pumps were fitted near the fuel tank. The small blanking plate was made from kitchen foil covered plastic card and two micro bolt heads.

Another few photos of the finished engine. I did try to find oil filter markings more suited to the 21st Century, but was not successful, so this miniature carries an old stock filter from 1962.

The gearbox was soldered together to hide the seam between the halves. It waas my first time soldering white metal and made me wonder why I had put it off for so long.I struck it lucky and there was hardly any clean up required after joining the pieces. What was a beggar was aligning the gearbox with the engine, despite a brass rod running between the two. I used datum lines on a plate of glass to assist and it all worked out in the end.

Thank you for looking in. any comments welcome. I did notice that the left hand distributor had broken loose after taking the last photo!

Thanks for the comments! The detail is all MFH. Although complex, and very rewarding, this kit is really just an assembly process - for a change.

 

Chassis GT 3757 has been apparently raced and driven almost continuously since 1962. Under Nick Mason's ownership, the car has had two engines, with one kept solely for racing, so the engines are kept very clean. The car has had bodywork and repaints, but the chassis and interior carry a patina of age which is the challenge for this build. I gave the engine a few simple oil paint washes but there will be no further weathering on that. The drivetrain will be more weathered, reflecting consistent driving. The exterior body will be pristine, but the chassis and interior will need to be aged and present as "worn round the edges".

 

The kit chassis is largely resin with a lump of white metal at the front end. The white metal was soldered for strength. The frame was painted in semigloss black and matt aluminium before having layers of oils and pastels added.

 

I also soldered together the oil and fuel tanks. The oil tank received a coat of Mr Color brass but without any primer being used. I then rubbed off areas of the paint and added some pastels to match the prototype photos. The tank is only loosely fitted in the photo below. I see there are some rivets I forgot to restore, although they will not be visible on the final model.

The kit is now boxed up and awaiting a shipping container. Hopefully I will see it again in a couple of months' time

I love what you are doing with this kit

The are really nice kits

I'm looking forward to see more

And yes the wheels very nice but a challenge

I have the aserati 250f in the stash and the wheels are the same

Take your time and it comes nice tighter

I'm working on the lancia at the moment

 

Will follow your progress
