Greetings,

Again, quite a bit of work - albeit largely invisible.  '71 Gray Ghost hood has been laboriously worked over to render its origins invisible - ha! The '64 GTO hood features twin faux hood scoops that had first to be ground down, and then attacked with a sanding block set on edge to comprehensively reduce the remaining 'hills' that formed the raised portion of each, blending the same to the surrounding panel work, etc. A vile task and not for the faint of heart.  Other additions are new resin grilles (cleaner these, better shape, zero warpage, etc.), a new coolant overflow bottle, and rough decal mock up work that, if nothing else, raises my spirits slightly.   

Back to the '70 Titus Firebird - an interior starts to take form.  Much floor detail (contours, stiffening braces stamped-in, etc.) remains to be added.  I must start somewhere though, and hence all the awful cast-in carpeting 'detail' has mercifully been deep-sixed.  No more pedals or pads, whereas a 'consoledectomy' was performed to erase the presence of an undesired detail. Material from a spare chassis was substituted into the hole where the hideous console formerly resided, whereas block sanding again saved matters for it generally looks the business.  A bit too thick of section and too tall though, with the panel work dimensions distorted looking back; i.e. T/G replaced the trans. tunnel body with sheet aluminum rather in the fashion of some gruesome stateside mid-eighties Pro-Stock racer.  A CDI ignition unit is seen forward on the trans tunnel, whereas the rudiments of a roll cage are starting to take form.  Thanks and kind regards...

Mike, that '71 Gray Ghost model is really starting to look good. The hard work is paying off. Nice job!

The Titus Firebird is looking a bit like some sort of sand buggy in that state. I'm looking forward to seeing that one take shape. Thanks for posting the updates.

Greetings,

A more substantive update of the 1:18 Sun Star-based 1964 Pontiac Tempest/1971 SCCA Trans-Am season Gray Ghost this time Ďround.  Glacial pace, yes Ė but hey Ė this isnít just a few parts added plus livery.  

Here a complete roll cage has been fabricated, though fairly simple of shape as can be noted.  An odd design to the extent that no tubes extend rearward past the main hoop.  For careful inspection one might also discern that a rear package shelf has been added complete with shoulder harness pick up points (two), the interior trim panels have been substantially trimmed and narrowed (i.e. necessary to afford clearance for the extent of the roll cage, whereas the dashboard still requires fitting), while GMP Trans-Am Camaro disc brakes have been added complete with dust cap (1:25 oil breathers) and axle end detail (GM-specific and scratch built).  Looking a bit meek in the style of early spot/single piston caliper/solid discs, Iíve doubled them up (these having been reproduced in resin) and hope soon to add ventilation detail for use of a tiny rectangular section file.  Proper caliper mounts and calipers to come.  Track has been increased front and rear for adjustment facilitated for the redesign of how everything is mounted.  A 1:18 Lane B.O.P. (Buick/Oldsmobile/Pontiac) differential housing is poised to be clayed up in anticipation of fitting the same to the chassis.  At this point precious little has been done underneath but for a fuel cell housing, hence much to do there.

The bend upward of the cross bar situated just back of the front windshield is reproduced in a manner slightly less pronounced than what is seen on the 1:1 ĎGhost, although this reflects the fact that Iím working with plastic castings versus scale-thinness stampings and such must be accommodated.  Given that the roof must be slightly smashed down even absent the roll cage to properly fit into place along the firewall, know that the dimensions tighten up further when modest pressure is applied forward.  The bars penetrating the floorboards forward will eventually be mated to the frame members consistent with tying the structure together entire.  Know too that the shifter housing/platform is indeed offset a bit  if not bent a bit (versus prim and mounted strictly straight) on the 1:1 racer, the pedal configuration isnít final, whereas the seat rails/mount hasnít yet been fabricated (this being a mock up).  Much floor work Ė especially looking behind the main roll hoop, remains to be done.

All-but-invisible is a new scratch built dual oil filter remote mount situated on the firewall (fifteen parts in total), an odd wet sump oil pan reflecting the choice by Team Trans-Action to recycle select T-G Firebird team parts (here a design used to accommodate 180 degree headers tested in Ď70), as well as revisions done to the fuel cell and fuel delivery system categorically unseen in the trunk.  The seat headrest is now sited with brass rod, while all I had to go on with regards to the configuration of the same is the old Motor Trend image roughly suggesting such.  Lastly, the beginnings of a large Harrison oil cooler to replace the somewhat mousey original GMP Trans-Am Camaro rendition of the same may be viewed resting apart from the model in some photos.  Top and bottom detail needs to be added, whereas the flange/mounting detail is an easy matter to create and yet isnít present within photos.

Fabrication takes time, whereas rendering additions consistent with affording the entire work an organic appearance is a challenge.  Many modifications work best when they canít be strictly detected, whereas configuring a first prototype involves pain.  Kind thanks...

Mike K.

Nice work, Mike. I like that miniature Harrison oil cooler. I am stunned and never picked up on the fact that there are no rearward support bars for the roll cage on that car. Very surprising.

Thanks for your continued interest,

Indeed - an odd cage configuration.  Perhaps Donohue's mulling about how it would seem a torsionally flexible chassis can perform wonders in the rain (and as mentioned within the space of The Unfair Advantage) is rooted in a faint remembrance of this effort?  

Seen below is the dashboard in place, as well as the seat mount fabricated from sheet plastic and brass wire.  The fiberglass sheet used to plug up corrosion in evidence on the passenger's side floorpan has been roughly created, while the obviously funky angle the pedal assemblies needs to be seen to.  Now the track appears a bit wide front and rear (to be shrunk a bit then), whereas adding a bit of negative camber to the rear suspension will come with the fitting of a better differential assembly complete with the camber adjusting flanges employed for each side.  The fuel inlet is too small, and is slated to be enlarged, etc.  Kind thanks...

Looking good, Mike. How are you planning to replicate the unique pattern on the metal dash face?

Thanks Jon,

Some items on the model will be used to form patterns on other material prior to finishing and fitting the same, with the dash cluster chief among these.  I'm hoping to cut or trim some reasonably thin hobby aluminum sheet for the cluster overlay, while for carefully drawing out the checkered pattern and further consultation with regards to photos, mask out and paint over the resultant panel with some appropriately frosted aluminum shade.  It's nice to finally focus on smaller matters versus endlessly mulling how I'll not be able to achieve some satisfying final result without the right rolling stock, the right flare contour reproduction or an appropriately fitted cage. 

...and now for some vintage Trans-Am History Detectives (ala the PBS series mind you)

Although perhaps to be followed up upon with a neat story/photo feature, a fun local discovery was made in relation to the G.G. days ago.  There exist various local sites that have historical interest to the vintage SCCA Trans-Am crowd here across SE Michigan, whereas the most well known might be the original buildings that constitute the Kar Kraft facilities in nearby Brighton, MI.  Of course, if one is sensitive to where the factory Trans-Am Mustangs were first fabricated, this is an important site and worthy of a pilgrimage if you will.  Anyhow, some curiosity existed within myself to seek out the residential property depicted in the period Motor Trend article where the Gray Ghost is being serviced/overhauled between race dates.  Just some suburban split-level in the middle of who knows where, children's bikes scattered about on the lawn up front, etc., while in total the very epitome of a low-buck effort/factory engineers on holiday.  Perhaps not the gates of Ferrari in Modena this, but given what I'm doing, significant enough.  Ownership of the topic on the part of this enthusiast? Check! 

Anyhow, closely reviewing odd copies Competition Press and AUTOWEEK (sorry to shout!) from late '71 I came across a classified advertisement relating that sponsorship would preclude fielding of the west coast races by Team Trans-Action, and that immediately after the MIS contest the Gray Ghost would be available for sale.  A Waterford, MI. address was afforded, while a small photo and telephone number rounded out the ad.  Hmm - was this the old Herb Adams residence, and might this be the property seen in the aforementioned Motor Trend feature story?  A quick visit to the library and research on the property revealed that address particulars had evolved and shifted (town and postal code in particular), whereas apparently the house itself was constructed in 1968 - so far, so good...

Wishing to respect the privacy of others and definitely not intending to telegraph as some confirmed Certified Web Creep, I nevertheless generated some typically scattered and all-but-incoherent MapQuest directions to the property under analysis - this approximately an hour away from where I'm based.  Fun it was to discover an address approximately half a mile away from Waterford Hills Road Racing proper - one could almost (almost) scurry a racing vehicle with open exhaust to the track sans trailer if the dare or wager was sufficient to prompt an attempt, whereas for allowing for the foliage growth, revisions to the property, etc., here indeed was the place.  Within the MT feature photograph the outline and pattern of the chimney seems to constitute the most obvious marker, while this matched exactly... 

Determined not to make a human spectacle of myself, scare children, etc. I did not linger long, although I do believe it would be worth it to compile a small packet of material to afford the current owner insight into some otherwise obscure history while also politely asking permission to reproduce the image, this to be done on some otherwise quiet Waterford Hills race weekend with my model set upon a platform in the foreground.  No strictly high hopes maintained if you will, but hopefully they'd recognize the request as being good natured and construe cooperation as harmless enough.  We'll see then...
