Gunze Sangyo Ferrari 250GT SWB

Recommended Posts

I've been wanting to start on this kit for a while as it's one of those "once in a lifetime" builds. It's the Gunze Sangyo "High Tech" series Ferrari 250GT SWB and it's a really amazing kit with most of its components in white metal as well as a huge photoetch fret including the wire wheels. I plan to build it box-stock except for replacing the admittedly awful tires with nicer ones from a Fujimi 250GTO. Last night I started the process by building up the chassis and getting it into Mr Surfacer Black primer.

It's a great kit, which will produce a great looking result. I hope you won't think of this as a thread hijack, but I think you might find the following useful. The etched egg-crate grille looks great, but it's not straightforward...

The numbering and order of the etch pieces in the instructions is wrong. This is what I did to build it.

I built it on top of a ceramic tile, stuck down some masking tape double sided, and on top a piece onto which I'd copied the outline of the opening by tracing a "rubbing" through with a pencil. The vertical slats are reasonably obvious (you know which ones the biggest are); the horizontals, not so much...

I bent the ends of the slats with a hold n fold, and then just tried each one in different vertical slots until it matched the outline shape of the opening as best as possible, using only the centre pair of verticals.

Until I got to here. Then, I hit the cross overs with thin superglue. When it had set, I flipped the whole assembly over on the tape.

Then I dropped on the remaining verticals, which I'd sorted into matched pairs. They're symmetrical top to bottom, so you can just bend the ends both the same way, and flip them left and right to match up across the grille. When they were all done, I applied the thing superglue to the joints, and I had a solid unit.

Which fits into the frame like this.

And looks like this.

I'm adding this because that grille put me off building this kit for two years, and how to do it is probably the single most useful thing I've learned in ten years of car modelling, so I share it with the hope that it will flatten a potential bump in the road in what is otherwise a fantastic kit of arguably one of the coolest cars on the planet:

Enjoy!

Best bonding adhesive for white metal or die cast is epoxy from my own experience. A bit messy to use it not careful and needs support whist setting.

Looking forward to following your build Justin. That GS kit looks to be one of the best Ferrari kits around.

Matt Bacon's tips about the photo etched grille will save you a lot of aggravation I would imagine.

Reminds me that I have a Fujimi Enthusist Kit Ferrari Daytona to build that has been in my stash for years that I ought to see about building!

So got a bit of time at the bench and decided to tackle this kit's signature: those gorgeous photoetch wire wheels. Fortunately, they're not nearly so tricky as could be expected. The combination of my AK Photoetch Scissors, a good fine sanding stick, and Bob Smith purple cap CA meant that they genuinely went together well!

Chassis is all together. It's kind of a shame that the chassis is missing so much in terms of detail. The kit front suspension has no front sway bar, no steering linkage, no steering gearbox, just a representation of control arms, some spindles that exist solely to give the wheels somewhere to attach, and some admittedly very nice metal coil springs. The rear suspension comes off much better which is good since the stance of the car means it'll be much more visible. I masked off the floorboards and airbrushed the frame and suspension with semi-gloss black, then picked out the differential in C28 Steel and the control arms in C8 Silver. I chose to leave the brake rotors bare metal, with the calipers picked out in Vallejo Metal Color Gold. The Fujimi 250GTO Avon tires really do look so much nicer than the kit tires as shown in the mock-up, BUT they're at least a scale inch larger in diameter than the Gunze Sangyo wheels so I'm either going to have to wrap the rims in sheet styrene to bulk them up OR wave the white flag and use the Gunze tires. What a predicament!

Even dream projects using highly collectible kits aren't immune from bodywork. In this case Gunze Sangyo saw fit to bless the builder with a good host of fine but noticeable mold lines which were difficult to see before a coat of Tamiya Fine Gray Primer. On top of that, there's some genuinely awful sink marks around the rear license plate. Out came the Mr Dissolved Putty to fill in those!

Got the front inner fenders in place and that meant finally an opportunity for a true mock-up. After much deliberation, I decided that the Gunze Sangyo tires will be okay for the build particularly since the stance does look quite good. A little bit more sanding and on will go the next coat of primer.

This past Sunday at the Cleveland Model Show, I was finally able to address a big concern hanging over the project: the paint. The car I want to approximate - though not necessarily replicate - was painted an obscure Ferrari color named Rosso Bordeaux. Unfortunately, there wasn't a ready source for just that color. Thankfully, Mike of MCW Automotive Finishes took some time during the show to try and match against my reference photos and we settled on Royal Maroon from his lacquer line. 

This is the first color coat, sprayed straight from the jar and then backed up with a mist coat of Mr Leveling Thinner to level out the paint.
