I Checked OUT of Rehab !- Ferrari 312B

[gp-models]

Very nice restauration of this car, good job!

Small update - mainly for APJ01....

The number plate is from our Mountain Bike Relay - that is my team name, and since I have friends in high places...LOL.

More updates later today, as I have been working on the engine - not "power unit".

So many fragile brittle parts. It is a frustrating day. As there are some parts such as the fuel injection pump and other front of engine parts that aren’t even visible on this car with the engine installed-I am going to cheat. Those wires and fuel lines are crucial to actually positioning the engine FULLY in the chassis. The stack up in the front needs to clear the attachments. Now I see why I had such trouble getting all this stuff aligned 45 years ago.

Engine is ready for disassembly.

Engine is disassembled and ready for a rebuild.

First thing to do is chrome the intakes. This is not Alclad, but Rustoleum “metallic” paint over testors gloss black

Cam covers and injection were stripped – I couldn’t get the black paint off the cam covers, so we will paint over what is there. It was really resilient paint!

Since I couldn’t get the headers off, I hand painted the block and heads. Used Magnesium Buffing Metalizer for both. Looking much better and ready for re-assembly. I am comfortable with the “used worn” look. Then I added some panel line paint for some depth in places.

The exhaust were sanded down, white glue used in the joints and gaps and will get painted by brush with Tamiya X-2 white with some dulling X-21 mixed in in a 3:2 ratio.

I had to re wire the ignition completely. I drilled out the broken spark plugs, inserted wire into the original ignition cables and glued them on the backside of the cam covers. The wire gives nice structure to the ignition cables so now I can bend them how I want them.

Gear box was cleaned up and repainted with Tamiya acrylics. I am trying different materials as Testors Model Master is kaput. So I mixed the Tamiya Aluminum with a few drops of Copper to warm it up a bit. Detail was with Gold Leaf on the differential side plates. The ignition box I left alone, and may tone it down with dullcoat brushed on, as the replacement decals only came with one sticker and it needs two….

Here is the finished engine about ready to get gearbox installed. I plan to put the chrome intakes on after the engine is in the car. I need to check the radius rods’ clearance to these, since this was the issue last time it was built.

Nice work so far Steve !!

[steveracer]

I have moved on to a little bodywork. Chinamalc, I have taken in your suggestion and removed the inner fairing on the front wings. I had already painted them so had to be careful on material removal. Not perfect but better I suppose.

Then installation on the nose, should look good.

Rear wing is complete, had to do a lot of fiddling and pinning of the parts on this one.

And completed the rear oil cooler and fairing rebuild. That was a real mess, with broken parts and lots of pinning too. It all articulates like it should now, and will “straighten out” when attached to the car.

I had a bit of a setback, as my spray booth got evicted from the basement. Wife has allergic reaction to a lot of things and this was the last straw. So I had to move it out to the garage (separate building) but it is quite cold. I can get it to 55 degrees F if I work at it. So my plan is to get my other models prepped (I work on a few at a time) and spend a few hours just painting out there, which is going to be better, as I don’t have the stress of worrying about her conditions. I can take my time. This car is pretty well done with painting anyway, it is the others that will benefit.


The next trick will be making some replacement parts with silicone mold and resin….stay tuned.

[steveracer]

I made my first mold from silicone, and a few parts. Very easy to do, and mirrors came out pretty nice. I lost these mirrors somewhere, so I stole a set from the McLaren garage when the mechanics went to the pub. Emerson is gonna be in for a big surprise at first practice.


Sorry for the small pictures guys.

Hi,

Nice job and great rehab for the 313B!
Well done.

Pascal

[mazyen]

Your 312B is looking good so far. I, too been restoring my old 1:12 F1 builds & finding them very challenging due to all the "bio degraded" parts.

[steveracer]

Some modelers have asked me how I disassembled the original built kits successfully. None of the models have any super glue, so they all are either old Testors glue or the Tamiya cement that came in the kits back then. I can tell Tamiya cement was different and similiar in composition to what they have today because I recollect the smell. LOL.

I didn't use any form of chemical on the parts, just prying carefully with my hands first. If that did not work, I used an xacto to score where the parts were glued, and that seemed to help a lot. Then lightly wiggle the parts apart. Some parts didn't come apart so easliy mainly the rear bulkhead, that is because I used a lot of glue on it back in the first build! So it took some of the red bodywork with it, fortunately that was on the underside of the model and is not seen. If it were on the top, some scratch building with today's materials and tools would be relatively easy. As i mentioned the headers were REALLY on there and I did not remove them, so I again, scored around the cam covers with an xacto, and pried them loose. I then maneuvered them out of the block and cleared the exhaust. That was pretty easy.

Just take your time and it should work out. The tiny parts are not so easy, and you will have to be careful and plan to scratch build some of these parts.

Don't be afraid. Don't be shy. I had nothing to lose except perform a better model of something special or hard to find.

No on to progress…

The halfshafts were a bit of a mess at the u joints. I cleaned the glue off of these and drilled and pinned for easier assembly. As these parts will effectively be hidden, I plan to glue them in place and paint semi gloss black. The tires will NOT rotate when done.

https://i.postimg.cc/hjW5FfzT/IMG-4468.jpg

The engine and transmission were carefully installed into the chassis. I did not glue this in place, however I had to move and mess around with the fuel injection lines as the engine did not want to go all the way forward. Those are the hang up parts in regards to engine location. As it is, the assembly is maybe 2mm from going all the way in, but it appears that this will be acceptable to locate the suspension parts. I also installed the intake trumpets and the upper radius rod mounts, painted metallic gray.

https://i.postimg.cc/nVK6JY1z/IMG_4657.jpg

The front cover did not fit as it interfered with the front suspension. I filed off the bottom and somehow it fit again so it snaps in place.

I had to move my painting operations out to the garage. My wife Is allergic to most anything and this is the result of health issues. I can warm up the garage with a wood burner far from the paint booth. The location of the booth is a temporary item for now, and uses a charcoal medium to filter out the paint fumes and particles. It blows right back into the garage, but I must say it is pretty impressive. I had it vented outside while in the basement, but lingering fumes in a confined area near the air pickup for the house furnace was moving the fumes through the house. Even I can tell the better air quality in our house, so maybe this is a win for everyone. I paint with about 45 degrees F, and place the parts near a radiant heater, so far so good….. Here is my $1.99 cheap arse thermometer-looks like I already ruined the thing with paint....LOL
