The Homestretch.

Model Car Building, What's new with me

There’s been a lot of new work and re-work on my 1:8 scale 1962 Briggs & Cunningham Jaguar E-Type Racing Coupe since my last blog. Test fitting of the front bonnet revealed fender well panels and the oil circulation port on one of the headcovers were preventing proper closure. It’s always painful when you have to tear apart nicely painted work. I accidentally popped the windshield wiper fluid reservoir loose while wrestling the oil hoses loose. Good thing is, I like the new circulation hoses better (even though I got the port angle backwards.)

The fabrication of a reasonably authentic roll bar was a real pain. What you see here is the fifth version I attempted. Getting the curvature right was the big challenge. I couldn’t get aluminum or brass tubing to bend right, and my 3D printer just couldn’t get the curves right. I ended up combining the 3D printed elbows with styrene tubes and a lot of putty to smooth things out.

Installing the roll bar system meant joining body assemblies in a different way than the stock kit was designed to join. I had to fabricate a semi-flexible flap and hinges to join the rear underside with the front underside so that there was a little give when it comes time to join the top with both sections of undercarriage.

The exhaust system had to be redone as well. The primer I used on the first iteration did not work well with the PLA 3D printed pipes. When I sprayed the silver topcoat, it warped the pipes. Once again though, I like the second versions better.

Next, it was time to paint the racing stripes. I took me awhile to find the right metallic blue color, but I located a great Tamiya match on eBay. Getting the masking straight was very challenging. I didn’t quite match the front bonnet to the body. My wife printed the circles and numbers on her vinyl cutter. I used masking tape to create a carrier mask to apply them.

The underside of the front bonnet needed some aging to look real, so I mixed a little cream-colored acrylic paint with Futura and airbrushed it to get that effect. Adding dirt was handled the same way: brownish acrylic paint mixed with Futura.

Foglight covers were especially challenging to fabricate. I found some bowlish-shaped parts from another model kit and adapted them for that.

Lastly, I modeled a wheel knock off nut in Blender and 3d printed four of them. It’s going to take a lot of work to smooth them out, but I think they will work.

Exhausting.

Model Car Building, What's new with me

I’m scratch-building an exhaust system to replace the stock piece that, I’m guessing because I have no reference photos, is not accurate for the real race car. Plus, there would be no mufflers to impede that exhaust! The stock kit exhaust chambers are right, so I will integrate them at the end of the new pipes. I have no idea what the real mounting brackets look like, so I made something up. To me, painting exhaust is always fun. I love the challenge of getting an aged, burnt look with a little bit of rust in some joints.

More Details.

Here are a couple more things added to the engine compartment: an air ventilation intake receptacle on the firewall that connects with the air intake pipe that runs from the front grill to the back edge of the bonnet, and a protective skirt in the wheel well.

Progress.

Model Car Building, What's new with me

It’s been awhile since my last update on my 1/8 scale 1962 Briggs & Cunningham Jaguar E-Type Le Mans Racing Coupe model build, so here’s some photos of what I’ve been working on. I’m almost done with the engine compartment, but I have switched to body work, which is very tricky. The stock kit seems to be designed for beginners who are not going to paint it. If, like me, you’re going to paint the body inside and out, you can’t assemble the monocoque following the instructions. I’ve had to plan out the sub-assemblies and how I’m going to join them in the end. I’m painting each of the seven body pieces separately. Thankfully, the real car has body seams showing.

I’m using Rustoleum 2x Ultra Cover Flat Gray Primer for the first time and I’m really pleased with how easy it goes on. The final coat will be Dupli-Color Super White II.

The real car has a British Racing Green interior color. I’m guessing the original Jaguar was that color inside and out before the Briggs & Cunningham livery was applied. I custom mixed my own acrylic craft paint to get close to the right green. It’s applied with an airbrush.

 

A Big Fan.

Model Car Building

The stock 1:8 scale Revell Jaguar XKE kit does not include the electric fan that cools the radiator. As I said in a previous post, this is for the most part a great kit, but is almost toy-like in a great many details. So, I scratch-built one. I didn’t get the scale right, but what’s new. I couldn’t find any reference photos of a Briggs & Cunningham Jag that showed the fan, so I referred to street car photos.

Under the Bonnet.

Model Car Building

I’m adding all the sheet metal work under the bonnet that is not in the stock kit. This will include custom fabrications for the race car, such as duct work for brake cooling and interior ventilation.

 

Details, Details.

I’ve made a correction to the break system: I had left off the dedicated rear master cylinder (I couldn’t see it in the reference photos I had), so I had to scratch-build another one and add it the assembly. Accelerator linkage has also been added, along with what I think is a fuel filter and a break fluid overflow canister. On the other side of the engine compartment I’ve installed the windshield wiper fluid reservoir and pump.

Making a Break For It.

Model Car Building

This is the scratch-built competition brake master cylinder assembly I just completed for my 1/8 scale 1962 Briggs & Cunningham Jaguar E-Type Le Mans Racing Coupe model car. Next, I’ll add a little black-washing for grime, then attach break lines. Once the assembly is glued into place, I’ll have to fish the lines through the car and attach them to clips with fittings where the hard lines connect to soft lines that go to the wheels.

S.O.B

Model Car Building

Some aspects of model building are a son of a bitch. Take for instance this dry sump oil system on my 1/8 scale Briggs & Cunningham 1962 Jaguar E-Type Le Mans Racing Coupe model car. I didn’t even know what a dry sump oil system was until I was trying to figure out what this huge aluminum tank was in the real race car. After a lot of research online, part of which was trying to find photos where I could actually see where all these hose go and what they do, I figured it out enough to model it somewhat accurately. In photos of the actual race car, I cannot find a scavenger pump, so I’m leaving it out. I also can’t see where the return hoses come from or go, so I’m leaving them out.

That’s just part of the S.O.B. Finding a reasonable facsimile of those hoses coming from the top head cover–to scale, and something that could be easily bent into a particular shape–was especially challenging. Rubber hose material wouldn’t keep its shape. I tried pieces of house wiring, but it was so hard to bend into shape. I had two pieces that I wrestled with for an hour or so. I gave up in frustration and went shopping for something else. I could’t find any soft wire that was the right gauge to mimic the hoses. I finally found some rubber-wrapped flexible wire cable ties at Home Depot. Even then, it was challenging to get the shapes and lengths just right.

The wire clamps, elbows, and rubber hose were difficult, but not terribly so. I know the brass wire is not terribly accurate, but I do like the look of it.

What you see here is where I’m at prior to adding some black-washing to the nooks and crannies for aging and post-race realism.

The next S.O.B. will be the heavy-duty breaking system on the driver’s side. I’ve been able to find pretty decent reference photos, but scratch-building it out of styrene will be tough. Then there is the matter of running the break lines. Wish me luck.

Back-tracking Again.

Model Car Building

This is what you have to do when you realize too late that the stock kit had a very unauthentic frame assembly and you have to scratch-build the missing components after you already have the engine and suspension in place. I did experiment with building and the subframe before mounting the engine (like a real car!), but the engine wouldn’t clear the firewall.

For those of you considering modifying the Revell or Monogram 1/8 scale Jaguar, talk to me! For the most part, it’s a pretty good kit, but many of the parts and subassemblies are toylike in design. I’m really becoming a proponent of building a kit twice, especially if you’re planning mods–once without painting to familiarize yourself with the stock models idiosyncrasies so that you can plan your build, and then the actual painted build. For this build, I had to really go against the order of assembly laid out in the instructions.

One other recommendation: Don’t be like me, and make it up as you go! Settle on the car you want to model and the level of detail you want include, then stick to the plan. I’ve always been impatient and too in a hurry to dive into a project, and I pay for it with a lot of rework.

It’s the Details.

Model Car Building

Here’s a side-by-side comparison of my 1/8 scale Briggs & Cunningham Jaguar E-Type Le Mans Racing Coupe model interior and the actual car which is in a museum in Venice, Florida. Still a few things to add. Not happy with the steering wheel. I worked with the kit wheel by filling in the holes in the spokes, but I keep getting seams, and it cracked, and the spokes are too big. I’m debating about scratch building a new one.

Overhaul.

Model Car Building

Here’s the Lucas Fuel Injection system I’ve been working on. As I mentioned in my last post, I started this model with a vague sense of the level of detail I would add toward modeling the 1963ish Briggs & Cunningham Jaguar E-Type Le Mans Racing Coupe. Well, I went all in! That meant re-work on the engine. So, here you see the 3D printed manifold, carbs, and trumpets installed, and the progress on the fuel meter. As you can see, there will be individual fuel lines going from the meter to the manifold.
