Greetings,

I am now in the process of mocking up what will hopefully be a shorter build than the last one. Experience and a little less complex (I hope) but even to get to this point has not been easy. In my case this is sort of a monocoque riding on another chassis and it has to function a bit like a supporting skeleton. I had a McAlistar Nissan GTP 90 body that I modified to be more like a Kremer K8 Porsche. It worked pretty well on my old chassis but doesn't fit the new one and so I started in thinking what could I do to modify it further and more to my liking. I love this particular version of the 1970 Ferrari 512 S so I thought I'd give it a go since the body is not worth anything to anybody but me. I've gathered lots of images, including blue prints and such and went about mapping things and pondering how I will do it. The body will be a mix of the front portion of the polycarbonate body and fabricated out of various things for the remaining 2/3's. I'll have to paint the outer side of the poly body so that the finish will be even in texture and shine between the mixed materials and I really do not want to try and remove the paint underneath.

Here's the aspiration and inspiration.

I finally cut away the center section of the body and started experimenting with materials as to what will work best for the body behind the front clamshell. My original vision was for it to be aluminum for everything but the rear fenders but styrene is so much easier to work with and so I will run with that...for now. The original rear fenders were spliced together pieces of RC plane wheel fairings/wheel pants. Great Planes makes styrene versions in two pieces and they come in a variety of sizes if you can still find them (they quit making this particular product a while ago.) Smaller versions made up the flares on my Jag project. The ones I found for this one are much larger - 11.5" long. I finally decided to yous to top side of the pieces because I don't want to have to fill seams and sand that much. The reinforcement and filler adds weight and I'm trying to keep that down as much as I can. I have to work one side and shape it and figure out where to cut to get the best shape. Once I figure out one side I can work the other. Slow progress, but progress nonetheless.

I took shots along with my "blueprints" to give an idea of where I am going with this.

My version might have slightly larger hips than the original.

The door has the radiator intake slope as part of its shape so this is a mock up out of aluminum flashing to help me get and idea of size and fit. It will actually have to be 2 pieces to make the full shape and I will use thicker aluminum sheet or styrene for the complete piece.

I would love to have wheels and tires closer to the original but will work with what I have. This back end will be rather complicated and I still haven't determined how I will join it all into one piece. That will come to me in time Lord willing.

That's coming along great! Wheel pants are a slick solution for the fenders. Why do i get the feeling hhere isn't going to be any nissan body in it when you're done?

Why am i seeing you getting the ferarri body made, then making a final 'racing' display one MetalMasher-style over it, with aluminum tooling foil?

Thanks - There won'y be much Nissan left to be sure. As for a racing display out of aluminum tooling foil, I'm not sure I am up to the task. I just want to get it done and move on to the two other body ideas kicking around in my head - Lord willing.

Fashioning the back end is surprisingly difficult in part because I'm approximating everything and my chassis is used for my other bodies so there are compromises. Ideally I should be using smaller front wheels and a slightly longer wheelbase so the challenge comes in making is still look nearly as sleek as the real thing - a sort of "Does this outfit make me look fat?" deal where a tweak here and there can still capture the right proportions visually even if they aren't exactly to scale. Another challenge is that the dash is really supposed to be further under the front windshield which in my case means splitting the front bulkhead so that is an engineering problem for the future to work out. My focus is to sort out the back end so here's the latest developments. The sides are now aluminum as planned and I will work on attaching the rear clamshell to them at sometime in the not too distant future. I traced the rear blueprint pic onto some opaque plastic sheet and that is very helpful because I can see contact points with the rear fenders and see where I might need to re-shape the bottom part of the fenders at the very back. The slope of the rear window actually ends just aft of the rear axle so I moved my temporary shell back a bit to see the proportions. So much tape holding this together. The green masking tape doesn't quite stick as well so I am using gaffers tape - a tape used in theatrical productions which has very good adhesion but leaves no residue. That's the black tape you see. I mocked up some of the rear winglets but and far from settled on how this will go because the real ones are pretty complex and sort of emerge out of the rear fenders in a more organic manner than I can currently produce. Here's the shots so far. i will be off for a bit as I have other things that need my attention, but I wanted to get as much of the rear sorted as possible while I have a moment or two.

Putting it in "H"
I really enjoy watching your builds come together. It takes a special mind to be able to repurpose things like you do. Super impressed.

Repurposing things is what seems to work for me - hence the moniker JunkGTZ since most of mine start as wrecks, discards, clearance, discontinued, or things not worth much to anybody. It certainly keeps the cost down for me.

Here's the latest. Still rough fitting, but refining as I go and getting closer to fleshed out. The rear clamshell will be all styrene with an aluminum sheet underneath to tie it all together. Screws into the sheet and then glueing all the seams of the styrene pieces and filling them. The rear canopy will be styrene too but aluminum flashing is in it's place at the moment. It cuts and shapes easily and can serve as a template for the styrene. This is turning out to be a bit more complicated than planned, but I am happy with the progress. I've got a busy couple of weeks ahead, and then the start of school and will have to lay off a bit and wait until later in February or March to do much.

The rear plate is cut but needs lots of refinement and a few more things added to it.
IMG_3087.jpg

The proportions are starting to get closer to looking right. I will thin the monocoque sills by 1/8" and the side panel by the same amount to visually lengthen things a little. It's a little heavy looking in the mid section from a side view.

Mad skills Sir!!!

Thanks very much. Means a lot coming from a prolific builder like you Joe.

I had a bit of a challenge fleshing out details on the rear spoiler because all my shots and drawings don't really show that in the best detail so I went to Youtube and found a number of shots in frames of paddock videos from this past year's Monza Historics and I paused and grabbed screen shots of some of the details I needed to render the rear spoiler and flaps and then went to work. It was hit or miss but I think I got something very workable.

The real deal

I'm at the point where I have to clean my table up so I can use my measurement map and rework the structure that serves as the backbone of the body. I am going to remake it for a final version that will allow me to more accurately proportion and size things. I need to narrow it slightly and lower the bulkheads slightly and workout the front bulkhead clearance issue with the battery. The table is a mess right now so I'll have to grab and evening and clean up rather than build anymore.

Worked on the rear clamshell a little more today. I added the bottom to the very back. I have no smaller model or photos of that part to go on so I am just making something that works with the chassis I built. I also started gluing a few things in place because it's time to move on from green tape. I cut the radiator exit vents and the real car they are louvered but I am not sure if I will do that. I can certainly do a screen piece by cutting a negative of the hole and pressing it into the hole with the screen but I might try a louvered cover on it. I just have to figure out how to make it.

The rear vents aft of the canopy are smaller than on the real car because I have a mounting brace for the rear part of the body. Compromises have to be made to fit and existing chassis.

It's slowly taking shape.

An overhead view. Most of my work ahead will be the middle section - doors and sides too will all need adjustments once I make some changes underneath.

The rear clamshell from the underside. I still have some of the aluminum sheet in there, but hope to replace it with styrene. Once the body is finished, only the mid- section (doors, sides, and roll bar arch) will be aluminum.

The elves were busy. Built a new skeleton underneath out of black corrugated plastic with some styrene reinforcements because the screws used to hold some of the parts together will not hold well enough without it. It more or less serves as a laminate to stiffen the pieces. I also narrowed it a bit to capture a little more of the stance of the real car which tends to look like the rear tires are just a little too wide - very aggressive. I also lowered the sides by 1/8" and will adjust the doors accordingly. I continued working on the back clamshell and tried my hand at making the back window and intake section out of styrene. It turned out better than expected, but there is still more work to be done. I also put in the backing where the rear lights will go. It is impossible for me to make this exactly to scale dimensions of the real car without building a separate chassis and I am not going to do that, so compromises have to come here and there, but I am pleased it is capturing some of the overall shape and stance of the real car. I will paint the skeleton all black and then finalize it gluing the pieces together with epoxy and making sure it is square. That has proved to be one of the single biggest challenges - getting both sides exactly even - in part because the wheel pants used for the back fenders are not perfectly even. We'll make it work!

How did you manage to get those wonderful compound curves in the rear fenders? Are the tops one piece? Did you heat them? Really nice.

i wish i had the skills to make them. i used some very large wheel pants for an RC plane made by Great Planes. They make a lot of different ones but they made various sizes of 2 piece plain styrene ones in 3 different sizes and i used some smaller ones in my Fatcat Speedster project that were about 7" long. The ones used for this Ferrari project were nearly 12" long so that's where my compound curve come from. you'll have to search a bit to find them because as far as i know they stopped making this particular one.
