31  Model Specific Discussions / Trans-Am Camaros / Re: Ideas to share concerning 1:18 '67-'69 GMP Penske Donohue Camaros. on: May 21, 2013, 12:05:11 PM
Greetings,

     Some further refinements to a 1:25 Jo-Han (John Hanley was the name of the original owner - and hence now you know) 1970 Mark Donohue Trans-Am Javelin with the Jimmy Flintstone resin bodyshell complete with flares.  Note that it has a scratch-built late-1970 season front spoiler intended to be aluminum with a pair of lexan extensions (note the split), whereas the brake cooling inlets are situated high up the assembly.  Viewed face-on they appear small of section top-to-bottom, although when viewed at an angle they make good sense for the inlet is positioned to route air down at an angle just below the bumper stamping headed rearward.

Other things attempted are both numerous and discreet.  A better front tire has been mastered utilizing a mid-'60's MPC kit release Goodyear Blue Streak Sports Car Special sidewall with the tread (such as it was) of a late'60's/early '70's MPC Goodyear Blue Streak NASCAR tire.  The tread of the latter was cut from a flexible vinyl kit tire, trimmed to reduce the outer diameter of such, and then glued fast to a round plug to which the better sidewall detail was glued.  Nice width, a good aspect ratio - a job well done.  

The rear tire is the late-season spec. '70's MPC Goodyear Blue Streak NASCAR fitment, albeit increased in width about 30%.  I'd ordered and contemplated the use of Perry's Resin Trans Am wheels and tires, but wasn't entirely sold on their use in 1:25th scale as contrasted to 1:24th.  Given this, what is seen here was worked up instead.  I intend to cast these in pliable two-part tinted resin, and employ the results across my 1:25 Jo-Han Javelin projects to-be.  Perhaps a '68 and '69 RKE Javelin someday?  A '69 entry would be especially fun given I've never seen such done in scale, whereas not so long ago there really weren't sufficient available photo images around to inform what needed to be replicated.  


...a nice Racemark seat employs two AMT NASCAR Matador assemblies to stretch out the bottom towards the knees.  The seat edge detail didn't strictly exist, nor did the headrest extend out as far as it might - hence these aspects were scratch-built.


...brass grille mesh then.  Inner wing/inner fender detail to be entirely redone from scratch, for not so much can be salvaged from what was afforded.  Surely the most labor-intensive aspects of this project.  The 'fiberglass' air cleaner housing is a resin casting of something scratch-built from before.  The center 'hardware' is new, whereas a flexible soda straw will be cast, bent to shape, and sanded to reproduce the duct work needed heading away from the firewall to feed said housing.  

A dimensionally shorter Jo-Han AMC engine was created for reducing the overall height of the block, flattening the base of the intake, and shortening the mains girdle area.  Jo-Han economized when tooling the later AMC V8 for revising some aspects of an older tool without wholly committing to starting anew.  Given this, the heads were wrong, the water pump and timing chain housing/casting are mounted far too low, and the intake as-delivered comes through with a noticeable dip visible front and back to fill in and disguise the use of an incorrect block.  Worse - to house this too-tall assembly, all Jo-Han Javelins/AMX/Javelin-AMX tools have front crossmembers dropped to accommodate such.  The use of the original tool engine results in a model that cannot be set at the proper ride height given the strange engine dimensions and everything done to disguise the use of it.  Here most everything is fixed.  


...note the Panhard rod chassis mount taking shape, as well as the larger-piston/outer body KONI double adjustable shocks taking form behind two pair of stock '69 Jo-Han S/C Rambler kit parts.  A bit longer, thicker across the top then.  Though very easy to miss, the cast-in rear bumper has been removed entirely, with a two-piece plug now substituting for it.  

A short, compressed wrap up then.  Underside view depicts a 1:25 Jo-Han '70 Rebel Machine front suspension grafted onto their '70 Javelin Trans-Am chassis, with a '69 S/C Rambler rear axle 'hump' and trunk floor, plus overlaid leaf springs.  The rear diff. is indeed an AMC Model 20 humorously afforded and supplied within a Jo-Han funny car kit (with keyed-axles - um-mm, I don't think so!). The leaf spring shackles are '69 S/C Rambler (one each from two kits given the shocks are staggered on the S/C Rambler, and not on this application), whereas I hope there will be enough room for the anti-roll bar (especially the odd clamped pickup points) and Panhard rod assembly in anticipation of creating like-assemblies for other (and usually larger of scale) projects.  

The rear bumper seen has been narrowed as have been the rear indicator/brake light clusters for as-delivered the whole assembly is wider then it should be.  Although puttied up and looking a bit strange, lastly one will notice the rear spoiler which employs the '71 and on ends which extend down a bit with late-season fueling inlet detail.  As the '70 Mark Donohue kit comes through, the rear spoiler is entirely flat of profile across the rear base; i.e. not what was desired.  Thanks...

With kind thanks to Justin McCutcheon for bringing this to my attention,

Previously I'd posted a link to the David Friedman Collection maintained by the Benson Ford Research Center at The Henry Ford.  Then it had just been launched, with but a rudimentary taste afforded concerning just what might be sampled - presumably on-site or via correspondence with archivists on the scene.  The later is still very much possible of course, but I didn't monitor matters to fully understand and/or appreciate how much is now simply up and accessible for little effort made.  Now a very enviable and powerful resource - a very mature and web-friendly archive waiting for you to inspect in detail.  Do see:

P.S. Afford them feedback consistent with correcting errors of classification and identification made to help sort matters out.  As this was written, the '69 Mission Bell 250 file was actually from '68.  Also say THANK YOU!

Greetings,

Something slightly beyond the fringe, but likely of interest anyhow.  Film capturing the press roll out of the '72 Penske Matador, four-wheel disc brakes hidden beneath less than svelte panel work, with SCCA Trans Am-derived road race know-how applied to the feverish unknown in sum and in total.  Be on the lookout for terrible period dress and gruesome wind-swept hairstyles, although both Penske and Donohue acquit themselves well in this regard.  See:

Greetings,

The discovery of a cheaper and more-effective means to reproduce machined lip detail for the wheels of topics that require such prompts me to update my '69 Welly/GMP Shelby Racing Co. BOSS 302.  Brutally tough on the hands to cut these down to size, but enough of an improvement afforded to merit the effort.




...before



...and after.  The opportunity was taken to refinish the wheel spiders with Model Master Stainless Steel overlaid with a dusting of Tamiya Pearlescent Clear - seemingly the way to 'do magnesium' given experimentation and comparison with my real Minilites.

Greetings,

A modest update - minor tweaking then.  The straight profile of the front bumper seemed off, looking particularly lifeless.  Others commented about the same, and while I didn't think I had sufficient material to do it, for reintroducing the profile I was simultaneously called upon to narrow the entire bumper assembly.  This effort had the effect of tucking in the ends and is consistent with cleaning up the frontal profile in a way that seems believable.  The mods. whisper 'factory car' to this enthusiast, although in truth I'm not sure if there was so very much done to the 1:1 vehicle in this respect.  So - narrower, pulled inward slightly, as well as upward and bending down slightly for how it is mounted.  Better I do believe.




Not breathtaking, but a new air filter element and base is in place, taken from the 1:18 ERTL Authentic's 1967 Camaro Z/28.  The height of the entire induction system including the cold air seal and cold air seal base has been reduced and is far better than before.  The photo images are not of sufficient quality to detect much has been done.



Oh, and a bit of latter-day forced perspective fun - pretending if you will that the smaller resin 1:25th version and the larger 1:18th rendition are equal in size.  The aqua-painted wheels reflect a later season spec., whereas the hood tachometer pod will have to be pulled.  Oh, and yes - the radiator support does tilt a bit inward from the bottom, although a touch exaggerated on the 1:25th model at present which features revised radiator and oil cooler detail.  Thanks...

Greetings,

A happy discovery here and update of something I felt settled, done, finished, etc.  Some firm known as Pegasus Model Accessories also does turned aluminum wheels in scale, whereas product #2399 23" Aluminum Stepped Sleeves replace the previous aluminum wheel lips employed.  Such feature a less fussy lip design, are agreeably tapered, and may have been fabricated from harder stock in point of fact.  

The previous effort cost about $45 spread across two applications/models and largely extinct on the market, whereas these are $9.99 the set and gasp, are available! Further, the slightly oversized diameter issue suggesting I'd 'upgraded' (not desired this) to 16" rims vanishes for the replacements are incrementally smaller in diameter - this judged good too.  Yes - the 'beak job' is coming - I promise!  Examining the final Mid-Ohio image suggests a very non-stock angle, hence all will be corrected and/or seen to.  Thanks...





Very subtle front bumper mount work, witnessing the further tucking in of the assembly relative to the panelwork.  





For near-endless revision of the 1:18th wheel arches, the shortcomings of the 1:25th resin-bodied version suddenly came into focus resulting in this update.  Taller and wider openings now both front and rear, and given the materials work quickly, this done in about forty minutes total.  So soon from now I'll attend a local club meeting where plastic is extolled and diecast is loathed, hence I sense that both projects should be displayed to quell quibbles.  The fueling port on the resin model is approximately right, whereas the 1:18th effort clearly needs to grow.  Thanks...

Greetings,

A website best negotiated with French language skills at the ready, with focus on St. Jovite, some BOSS 302 material, and modest focus upon a racer identified as Richard (Dick) Brown.  Some unexpected images, one a '69 backdated T/G Firebird wearing atypical ARE CP-200/Tran Am wheels and yet not the MIS Tunnel Port 303 paddock conversation piece.  See:

Thanks for the kind interest,

An attempt here to reproduce some detail seen on the 1:25th plastic version of the Gray Ghost a while back, for I've created a mold of the grille sans identification, creating two in total, and have flattened the profile of the front bumper (as opposed to the 'vee' as per stock).  Further, the opening witnessed within and across the front bumper ought to have continued both straight and flat where the license plate mount is seen, and hence what additional material rose above this opening has since been trimmed back.  

A bit of a muddle at present for the result appears as menacing as a slow-moving nurse shark.  Clearly the bumper needs to be both raised and pulled further back into the panel work, but strangely meek it appears in total.  I'm sure it was the right choice to make, whereas filing off and rebuilding the Pontiac 'beak' on a slight diminishing angle will help consolidate matters visually.  It seems Trans-Action (the official name of the team then) had an eye on the Holman and Moody Torino Talledegas to the extent of discreetly cleaning up the profile up front.  

In other news, the resin intake was added, further refinement of the upper control arm mounts and blending of the chassis to the added GMP '70 GTO items is in process, while an incongruous Orbit Orange painted hood tachometer pod replaces the Lane '68 Firebird part.  Kind regards to the community with much appreciation...

...before, and such will look better for the front bumper is body color and the grilles reflect back a chrome finish.  The standard grilles are in fact stamped aluminum, hence no profound worry that I'll not be able to strictly see to this via the use of Alclad lacquer.



...slightly underwhelming, if not slightly dumpy.  The bumper will move up a bit, and further back surely.  The 'loss' of finishes detracts from what work was in point of fact done, while looking at now-prominent 'beak' suggests a nose job is surely in the offing...



...still requiring some work to clean up the side indicator pockets wish bear evidence of unneeded extra material.  The headrest is too wide as well - this slated to shrink from side-to-side.  The resin intake pokes through, while yes - I do have to reduce the height of everything to ensure the hood may close, etc.

Greetings,

I haven't ordered materials online from them, although the website is clean and their 1:43rd footprint within the scene a longstanding one.  If there were issues in relation to poor reputation, I suspect such would have surfaced long ago.  The models I've seen displayed at shows impress, with brief notes of such to follow. 

Many of the Trans Am tools employed are now quite old, although for many years indeed such constituted the only game in town but for larger unassembled plastic kits and independently pursued kit mods.  The finish quality of the models is high, whereas odd to note in a sense that 1:43rd hand-built factory releases are commonly produced to a standard that well exceeds what is seen in 1:18th.  I would recommend that modest caution be displayed in relation to the secondhand market for I'm not sure how sensitive the decals and artwork is to sunlight, etc., although recent builds based upon the old tools shouldn't worry you.  Some fine photo-etch work won't respond well to handling, hence wise it is to keep the model within the display case and atop the factory plinth the item is delivered upon. 

Kits exist of the same range, but personally I'd recommend spending the money for a high-quality factory build and simply honor the expense required to afford what is on offer ready-made.  These are jewel-like, and hardly the stuff of mindless mass production absent sensitivity to the topic.  One word of caution though!  I have vague memories of the '70 Penske Donohue Javelin coming through factory finished sporting the wrong shade of blue (too dark I believe - and a metallic finish too!), so in this discreet albeit important respect one is forced to consider the building of 1:43rd kit so that this detail might be attended to.   

I suspect as the new-tool Chinese-manufactured 1:43rd SCCA Trans Am topics continue to emerge on the market that the demand for the older tools will slacken still further, but also know that these earlier tools are in the main not hateful even as they are (and always were) a bit pricey.  Some topics likely will not be revisited, hence for some items, perhaps best it is to celebrate that a firm has decided to replicate the topic and spend the money if so-moved.  Kind regards...

Greetings,

A link guiding you to a thread current on another board, this being The Roaring Season.  Contributions from 'our own' Bruce 302, with lovely color images of the T/G Firebirds as seen in 1971 (I could be wrong here, although I believe a lighter body color with either green or yellow numerals would identify them as late '70 season images), in addition to an image of one of the T/G Firebirds that was converted into a Camaro bearing evidence of an unfortunate off.  See:

Thanks for the kind notice,

... the intake is well underway.  Mounting flanges and base recycled from 1:18th GMP '70 GTO, whereas the individual levels of the two-plane design constitute two layers of plastic sheet shaped to suit.  A base for the water inlet was taken from the 1:18th ERTL Authentics '67 Impala SS and reused here, whereas most everything else was blended together for the use of putty.  Though a bit muddy in the photo image provided, the cast-in manifold heat passage has been added, while 'burning it' together via the use of clear lacquer discolored matters a bit.  When a mold is made of this, all should blend together in an agreeable fashion.

The carburetor base combines two castings formerly scratchbuilt to reproduce a fair Hurst S/S AMX cross ram intake.  The rear of the manifold flanges required sectioning in of material to reproduce the solid contour seen in the photo atop the model, whereas other discreet additions will in all likelihood bring it to life.  I may cover the part with a dusting of baking soda scattered atop a layer of clear to afford the entire assembly a bit of surface texture.  

This prototype is a bit raw, whereas modest additional detail will be added including attachment points for hardware, linkages, etc.  For use on the '70-'71 season Pontiacs then, hence one for the '70 T/G Firebird (with hack and slash mods. for the first race if I so choose given they tried to slip a short deck block past tech.), one for the Gray Ghost, and perhaps one for a B.F. Goodrich Radial 'Tirebird' if such is ever attempted.  Proceeding ahead then.

Thanks for the link, Mike. Some really great photos there and I was surprised to see me in there as well (green arrow) as well as my parents and younger brother.

...how neat!  The photo collection was referenced by others on another messageboard visited, and if anything I was slow to post it here.  I so wish I could have experienced the road racing scene much earlier in life 'live' if you will, whereas there you are on a family outing no less - wonderful!  Thanks, and sorry so slow to respond...

Greetings,

Perhaps not enthrallling, but how engine setback is accommodated in 1:18th scale.  Plastic sheet in two thicknesses, with the weld bead clear nail polish applied thin on the edges that meet, and rather thick consistent with pushing the material out from behind.  The heater core cover is also new (it seemed fabricated rather than a delete plate), whereas left of the cowl seal is where fuel is routed to the carburetor.  Concerning the firewall - more exciting seams and bumps to follow.

Though not witnessed here, the accessory drive configuration has been altered to the extent that the alternator has been repositioned to the left and down, while I'm trying to source fanbelts both small and large enough to suit the application.  Odd setup in use whereby the top pulley and bottom run in tandem for the use of a single belt, whereas a second pulley 'row' is employed on the bottom to run the alternator without 'involving' the top pulley at all.  Well - that's how I discern matters in the period photo seen above!  Pushing the bottom pullies outward required some analysis, such which revealed that no harmonic balancer was present on the scale representation of the Pontiac V8 employed.  For scratchbuilding the same, problem solved...  

I've gathered material to scratchbuilt a Edelbrock R4B intake which is a dual-plane design appearing very much like a squashed octopus when viewed from above.  As contrasted to the intake seen on the '72 Adams/Milt Minter Firebird which appears very modern by way of contrast, this earlier design is and will be very 'old school'.  At first the GMP intake seemed something I could use, then something I could modify, whereas now it will serve as a dimensional template.  Why all the fuss?  This I cannot tell you.  Thanks...

Greetings,

Only modest changes will be noticed even for the considerable labor required to afford such.  The foam cold air seal ring was trimmed to reflect the revisions made to the 1:1 item for use on the Gray Ghost, but pity I misjudged and cut carelessly.  Further, I could not determine how to reduce the height of the seal which needed to be at best one-third as tall as the stock seal.  Perplexed, I opted to create a mold of the seal, to latter sand and shape the result pulled from it for use here.  The casting was mounted on a round plug to stabilize it as I went about the process of both thinning the part top to bottom and shaping with care the areas the otherwise would be the two smaller circles that blend into the cold air seal as per stock.  A good result achieved, but very very tedious...

The original firewall structure has been reintroduced to the work after first sanding off the face of the same and filing in the opening necessary for the home-brewed cowl induction setup.  What was an empty void behind the fabricated firewall is no longer.  For reemploying the structure, the forward end of the roof assembly can be positively sited, as can be the dashboard that now reappears on the work.  A seal is further seen on the firewall, as well as structure to support the brake master cylinder.  The black box to the top right of the firewall is a wiper motor.  Thanks...

Hello,

Modest update depicting fabricated inner wings being shaped and sized.  Full-length top-to-bottom nearest the radiator support, tapering a bit towards the rear, plus slightly stylized control arm cutouts for each side.  The opening for the hinges will be enlarged, while the bend nearest the firewall on each inner wing will be fabricated and added soon.  Not terrible as a baseline.  One notices four holes drilled atop each assembly, these positioned well forward.  It is my understanding that one could remove spark plugs and situate them within these holes as needed.  Thanks...
