      Not Supported Restoration Scratch Built

      Inspired by some nice work on this site and other places recently, I rescued a couple of long-forgotten very old, very sad Pocher kits from my mothers house.

      They were both built very badly by an incompetent idiot. I know this to be true, as the builder was a younger version of me, to the tune of about 25 years.

      anyhow, the items in question are a mostly completed Mercedes 540 and the Ferrari F-40 engine I'm currently rambling on about.

      The Mercedes is parked for now.

      So to the F-40 motor.

      Having recently finished my MFH Brough Superior, I've been a bit spoiled regarding what a decent multimedia Ferrari F-40 engine scratchbuild kit can look like in 2020. I also had a look at sourcing an autograph F-40 engine transkit with little success, plus I'm not really willing to pay the crazy money the last few in the world would command.

      So bearing those two things in mind, I set about the old motor, which looked a bit like this when I started



      Pretty grim.


      So having striped it down and removed all the paint and other goo, standby for some modelling heresy - Pocher models are a bit rubbish. OK, actually really rubbish IMHO. there, I said it.



      OK so I know I'm looking at this with through modern eyes, but I never understood what they were supposed to be even at the time - expensive, terrible fit, often inappropriate materials, screw together, easy assembly, not intended to be painted in some cases, so I don't believe they were ever actually aimed at modellers.


      I was planning on replacing some of the worst bits with various scratch-built and turned items. To cut a long story short, apart from maybe the gearbox, it's all the worst bits.


      So I rolled my sleeves up and got stuck in with something 'easy' to start with. I give you the Delco Remy 105A Alternator as fitted to the venerable Ferrari F40.




      So armed with my trusty PC, iPad pro, apple pencil, shapr3D, fusion 360, resin printer, and mini lathe I set forth.







      So far so good. A steep learning curve involving CAD and resin printing supports then ensued.

      Some time later...





      Add primer ...


      And finally paint ...







      Compared to the Pocher part ...



      So although this is one small piece, it does prove my workflow which is now repeatable for the rest of it. I've learnt a load of new skills including CAD and how to get good results from my cheap little resin Ferrari F-40 engine scratchbuild printer. Which BTW I'm absolutely delighted with (Elegoo Mars) if you want to google it.

      This is my new go-to modelling tool.

      Thanks for looking.

      Regards,

      Nick

    There’s more to it of course.

    When you start out object modelling, you need to choose between inside out or outside in.

    I didn’t fully grasp how important this concept was.

    So outside in means you care about the look of something, the internals are secondary.

    If you were designing a real engine, it would be the opposite. So the crank shaft, con rods, pistons etc would be your starting point and they eventually would dictate the shape of the block, cylinder heads etc.

    In my head, this is a model, so by definition cosmetic - if it looks OK, job done, right? So outside in is for me.

    Only later did I realise that actually inside out makes more sense. All the Seemingly random bumps and humps on various castings are dead obvious when the internals are considered.

    So I learnt the unseen but easily derived ( eg cylinder/valve spacing) informs external shapes much more readily than guessing ever could.

    For example, the pent angle on the combustion chambers is driven by where the valve stems emerge on the top of the cylinder heads.

    OK bad example as the whole thing is hidden, but it all informs the various geometry of this thing.

    Sorry if this is a bit rambling, but it might help somebody.

    Regards

    Nick

    Yes I understand. Models are about the exterior but without the internals the bones if you will. The flesh would sag.... good to know the internals. You need to know what a machine is supposed to do before you can work on it. Your explanations make sense to me. By the flag next to your avatar I take it you are in U.K. I lived in mildenhall for three years. I know the cost of living there. In the U.S. some things are a lot less expensive like fuel for example. Holler if you need anything. I had started a 1:1 Ferrari F-40 engine scratchbuild triumph spitfire restoration and sold it when I left.

    Really? that's very strange I still have 1977 Spitfire in the garage at my mothers house, it has a fully blueprinted engine twin Weber DCOEs etc and I spent so much money on it at the time (back in the 80s) that I could never bring myself to sell it.

    Terrible thing now I look back, truly awful transverse leaf spring rear suspension, super-weak three bearing block overbored and overstroked to get to 'enormous' 1500CC capacity!

    I worked in the US for a while in West Chester PA so yes, things are a lot cheaper, I know.

    regards,

    Cool. Here's an example. I picked up some batteries the other day for one of my builds on the super cheap. Check out my current builds by the way. Only one person has commented on them. People must be busy or Pontiac's are getting no love. Say you wanted to do a L.E.D. lighting kit for your build. I scored some 18650 batteries to power electronics and will will utilize an arduino in a simple circuit to do sequential light kit on my 1/8th. The example I forgot to add pictureFerrari F-40 engine scratchbuild-20200817_103216-jpgme charging my cell phone batteries. They can be used if you need to conserve space. I just noticed that circuit board attached has a neat little push button on it. Gotta save that for my electronic parts bin. The ugly pink batteries came from NEW laptop battery pack. Who knew laptop batteries had a reset switch.... not this guy. My spitfire was a red convertable unsure of specs or even year model. Many projects ago. I remember that the parts were sky high I had to custom order a fender, when they were made the panels were hand made not stamped out like most are today. Today my skill level would have allowed me to repair the old one. The guy I sold it to lived in mildenhall. New fender was in the back seat. All original garage kept. The military would have shipped it here for me if i changed out some parts like glass or bumper or some such for free. Import regulations. Now that I think about it now..... I probably could have took those parts off and shipped them separately. They probably thought of that.....Import regulations probably required the tempered glass and reinforced bumper be installed before shipping.... been so long ago I don't remember. That car would have netted me a small fortune here. Hindsight is 20/20. It would have been a good investment. Find someone in the military going to ship back stateside and you can probably sell it to em for enough to build your dream car. They have to be married with their family there to qualify for the free car shipping. That is of you do the mods I have described. That is if you have lost the love for a project car. You may just want to hold onto her. They are rare here to be sure. Sold it instead.... Both my current builds are 1977. Works in reverse too. Married with family get to ship a car to the U.K. for free. As customs or import regulations are not as strict going your way... anything goes. So..... be nice to us damn yanks especially if they are married in the military. The single ex military ones like me are a bunch of w_____rs. So feel free to cuss us out as we are d___ks. Lol. Find you a military friend over there and take him or her under your wing. Sell the car to them.... plus they can buy cheap alcohol Ferrari F-40 engine scratchbuild and cigarettes. Nasty habit I know. I would buy a carton of smokes for my ex's mom that was in a generic white box that said cigarettes on it. It cost her less than she would pay for one pack. If you don't smoke, well good on you. I am great at quitting. Not so good at staying quit. Sounds like the plan maliciously grinning evil yank. My plans for world domination have been postponed due to the two current builds I am working on.... ok I give it a rest on this novel.

    So I've mostly been working on cams and belts today.

    Got the first belt modelled (they're not the same unfortunately, so I need to do it all again for the other side.)




    And printed out the upper pulleys as well reworking all the waterways to better looking finish than I had originally.

    Such nice work! Your renderings and actual built assemblies, side by side, are a very effective way to demonstrate your techniques!

    Again, thank you for sharing!

    I noticed pocher parts are going on sale new threads popping up. Great work by the way. They make very small lithium batteries by the way that make this1 look big.

    Could sculpt one up for you into a pocher part so stock original look could still be achieved..... hmmmmn

    Wireless charging is also an option. When you put her in her parking space she charge herself up on the supercheep. Tech just keeps getting better and better.

    Keep an eye out for red convertible spitfire she may still be in country. Small world. She was running like a top when I left her behind. Nothing like yours tho. I didn't have a garage then...... really digging your build.

    She lived under a car cover for a short time in her life. Shame to cover something that has curves like that on her. CarPorn. Lol.

    A real push at the weekend to get all the CAD bits I’ve been avoiding done. So I completed the throttle bodies on Sunday, and the three intake plenums done today. There’s very few straight lines on any of these things!
