  1. At long last................

    The veil of secrecy has been lifted so here is the latest creation from the far reaches of the mind of David Cox. And his cluttered workbench. The long gestation period which has tried your patience was due to numerous factors; weather, illness, complexity and of course the incorporation of zany or quaint ideas.

    Yes it's a Rolls Royce and some of the bits were once in a Pocher box. But they have paid the heavy price of meeting David's saws, knives and gritty bits so that they are only recognizable by their ancestors.

    The original configuration was a Phantom II torpedo but not the way Pocher would have you believe it. As you saw in an earlier post, David's magic has created a straight eight cylinder engine – from two Pocher based sixes. Although the real Phantom IV was a straight eight, this is not a replica of that engine. It IS a viable, correctly engineered version as cast and machined by Rolls.

    Using mathematics known only to Archimedes, much hacking and joining of frame, body and drivetrain sections was perpetrated to accommodate the stout new addition. Not quite one of his 'Monsters', but surely a tour-de-force (again) about what skill and imagination can get out of a Pocher carton. Sit down, tighten belts and be prepared for the unexpected...

    Like making a Rolls straight 8 engine from a Pocher 6. Warning; extensive spare parts from a few kits needed for several areas of this build. Something very few of us have but David has gathered derelict kits for decades.

    The technique begins by inserting a shortened cylinder block (three cylinders cut down to two) between two stock 3-cylinder blocks. A spacer is spliced into the crankcase (the lower engine block).

    AIMG-0489.jpg

    Seen here is the extended crankcase with insert and the massive 9 main bearing crankshaft and 8 connecting rods. They were added for strength. For engine boffins like me some numbers; a standard Phantom II engine of 6 cylinders was 7.7 liters (468 cubic inches) with a 4.5” bore and 5.5” stroke(!) and compression was 4.75:1.

    But David's enlargement to 8 would have 10.2 liters (624 cubic inches) and low RPM torque approaching 400 lb/ft – needed to urge this 5000 pound fast touring car. By contrast, my Cobra's Ford V-8 has only a 3.78” stroke but its 4.23” bore allows much more power due to camshaft design and huge breathing. Indeed it produces 502 lb/ft torque at 4800 RPM. The Rolls was designed for fast touring and lumbering around town, not racing. Rather like an irrigation engine designed to run at low RPM all day under heavy load.

    Work progresses as detail is added but the size is clearly evident. It's as big as some complete 1/24 models.

    CIMG-0518.jpg

    Here David dived into his parts bin for much of what's needed. He has added spacers to the exhaust manifold and we had a small debate about that. I contended he would need two more exhaust runners to the manifold so each pair of cylinders would exhaust into one port. In his marvelous fiction-world and since this was a crossflow aluminum head, he was content to believe the exhaust routing would all take place in the casting. Well-it IS his model so who am I to nit-pick??

    DIMG-0523.jpg

    Moving ahead you can see that every bit of Rolls linkage, line, hose and plumbing on the real one is on David's. There are now 16 sparkplugs, one distributor (note Alfa 8 cylinder cap), one magneto and 16 h/t leads. In true fashion the linkage from the distributor goes forward, then traverses the head and runs aft on the other side to sync with the magneto which is driven by a lengthened shaft from the generator. Two cylinder heads and two valve covers were also mated. These things take time...

    Peeking ahead into the mock-up phase, we learn that the firewall must be displaced to accommodate the new big brother. Nothing cut or added at this point, just looking and head scratching.

    FIMG-0579.jpg

    A further peek at mock up shows how the engine elbows its way into its new home. To understand the enormity of what to come, note the gap from the leading edge of the hood side panel to the grille shell. Enough to make many of us duck under the covers.

    Having just described engine construction, I'll pause a bit and organize more photos for the major build details to come. But first a word of thanks to Dave Cox for freely sharing his advanced and creative techniques which we can enjoy here. Folks buy his books to see this but we are most fortunate. Possibly because I've hounded him incessantly about every facet of his work. And he loves knowing there are a few Pocher enthusiasts sprinkled across the Earth who enjoy this.

    Back soon as I have a beverage and a lie-down...........:phew:

    . The rear tires are actually hitting the inside of the interior before they come anywhere near the leaf springs. I may have another trick up my sleeve yet though as they are not on there permanently. 

    I'd caution you not to dismantle and hack the beautiful work you already did. The car looks great and I'm being far too anal.

    For your next drag legend car, mock-up like crazy 'cause kit manufacturers seldom pay attention to their subjects and are never expert on what's right or wrong...

  3. Mustang - (change your name to ;Maverick !) you have absolutely nailed the car's look as it sits today. Dyno would be pleased. Can't say more than that as praise.

     

    Being a race-tech geek, I have one concern however. Haven't looked at NHRA rule book from the day but I'm not sure the rear tires should exceed the bodywork. The 1:1 pix look like the tire shoulder is right there. I think if I were fortunate to build the model as well as you, I would narrow the rear end so the tires are level with the body edge.

     

    Forgive me being a nit picker  :mental: - but it takes nothing away from the character you've built into a great model.

  4. Great to see this back - you've lost no skills in your absence here.

    Beautiful, surgical assemblies created from tiny bits. This kit appears a very big project - not just for its amount of parts - but for the parts that REQUIRE re-engineering inadequate bits.

    This has now become the primary reference build of this big Tamiya project - well done and carry on...many F-1 builders can benefit from your sharing. :worthy:

    The tension is building.....

    Well I'm here to assure Poul and any other Pocher Rascals that I am not teasing to raise interest. I suspect that long-standing pinned topics become like furniture and we tend to not pay them attention after long periods. And I don't want any interested parties to miss this.

    But I have received the bulk of the build information and near all of the David's photos and am in the process of organizing all - that's after I get myself to understand all that he is presenting in this build.

    It looks to be the most altered Pocher Rolls overall (that includes the aero-engined cars and straight 12 cylinder cars seen earlier) that he has ever done. So no, not teasing. I'm hard at work assembling this material and one fact is evident; I must present it in a series of posts to bring it all to light, not just an 8 or 12 photo feature. That also gives you all a chance to ask questions, laugh or hurl invective.

    As evidence of the above, here's the dashboard and forward cockpit, on David's bench, sprinkled with sanding dust - a Cox build trademark. The astute will question the large chrome lever, switch, control rods and wires scrambled on the floor. Most of us would be thrilled to accomplish the veneer dash or perfect leather alone. Can you guess what's afoot here? :shrug:

    Yes, I'm teasing a tiny bit here but back soon with another full fantastic Cox journey. I doubt any can ridicule that statement when all is presented....

    Back to work...:devil:

  6. You have done excellent work and must have fine references. I'll add this one but you may have it:

    https://www.mecum.com/lots/FL0112-121252/1970-ford-maverick/

    After several owners I figured the car was restored with non-original parts. But this says no, only modified to make legal for track use now. So probably the cage and fuel lines and fittings.

    But I had questioned some things that made me look. Almost never see tubular intakes painted or coated black - they retain heat. All I've seen are cast ally (in the day) or modern fabricated and tigged ally (Hogans). Also, most SOHC's had valve covers that were beveled on one edge - this does not and it shows in the link pix.

    Those Holley 4500's by Future are excellent for such small scale and your treatment is just race-right.

    Great job - keep going.

    Thanks for coming back Codger. I might go for the Continental if I decide to go ahead as it will be much easier to remove a scale 2.5 inches from the chassis rather than lengthen it.  we will see!

    If I follow you Noel, that would require ,312" removed from the Pocher chassis to yield a scale 144" wheelbase Conti chassis. That can easily come out of the drive shaft and brake rods or possibly shortening the transmission. However the firewall must be moved back also, for engine clearance. But attention needs be paid to tire/fender openings / match and the trunk may require shortening. Not sure, I'd need the parts in my hands once more to fiddle.

    Well worth the effort  as this Gurney rendition shows. It's almost a catalog of all the Gurney trademarks - level louvers, flat hood and beautiful fenders, You'd need a Pocher Ambassador for those fenders or a set of MMC's resin ones - if you could find them:

    1931-Rolls-Royce-Phantom-IIContinental1.

    Hoping you post if you go ahead. :devil:

    OK, I'm taking a stab in the dark, but please follow my thinking. Zvezda released the C-130, a plane used internationally and quite popular, so sales of the model, given generally enthusiastic reviews, should be brisk. I have to wonder if Zvezda would consider a Constellation. Not likely we'd get one of the early models but one of the 1049 series, which was widely used by a large number of airlines and saw military use too. I'm confident model companies do, in fact, review modeling web sites from time to time and I suspect the interest shown here just might be cause for some consideration. My two cents worth.

    Well things happen fast! In response to SAT's post here I decided nothing ventured nothing gained so I went directly to Zvezda's web site and sent the following email:

    Dear Sirs,

    I am a member of a model building forum in the UK and many of us have expressed interest in a new tool model of the famous Lockheed 1049 Continental.

    Here is a link to my posting on that forum and the enthusiastic response by the membership:

    https://www.britmodeller.com/forums/index.php?/topic/235082656-l-1049-connie-where-are-they/

    Your company has been highly regarded for excellent models by our group. We hope you see enough interest to create and model in either 1/72, 1/48 or 1/32 scale such an aircraft. We have expert model builders here who can easily accomplish such large scales. To my knowledge, there is currently no other such model available by any other manufacturer.

    Sincere thanks and am looking forward to your response.

    And then I saw the Admiral's post !

    I hope you all are pleased with my presentation. So at least we have some irons in the fire. And I finally did something besides whine...........

    Will keep you posted.
