Ya, I can post photos again!! :D

More pics of WIP progress

During cutting out of driver's door, upper window perimeter seal is reduced in thickness, to much to be reused & look proper

1459059_537454533014927_988959901_n.jpg

New upper window perimeter seal is created, and fitted to contour

1459059_537454526348261_375729085_n.jpg

Upper window perimeter seal fitted with smaller seal tab on inside edge, and formed tabs to each end, for realism of real production part once painted. Lower door seal created, and will be attached to final painted door, and also painted flat black

1459059_537454529681594_1296167452_n.jpg

Interior door frame built up to replicate production sheet metal, including forward door hinge pillar. New door sill kick-plate created, with photo-etch part created, Thank you Joseph! :) for realism of production stainless steel part which sits in the kick-plate

Further scribe work on the body shell, to add realism after being painted, by keeping edges and panel lines crisp

1391914_537466366347077_1226017576_n.jpg

Visible edge of front fender, because door will be in open position, is thinned for realism

1391914_537466359680411_165204705_n.jpg

Inner edge of each fender wheel well opening, is thinned by cutting inward at an angle, to create thinned edge

1391914_537466353013745_899509328_n.jpg

1391914_537466356347078_843772878_n.jpg

Stock kit body shell missing gap between roof A-pillars and front fender, new joint gap created here for proper realism

Drill out the rear bumper side markers, so new clear plastic pieces can be created and installed later

1467301_537472219679825_674469502_n.jpg

Stock kit body shell has deep molding scars at each of rear bumper corners, so must be filled to correct problem

1467301_537472223013158_816019528_n.jpg

With drivers door opening completed, interior panels must be trimmed to correct shapes for realism. Dash board edge created with styrene, for correct look and shapes, for realism, as will be visible in opening upon completion

Thanks Tom, Carl & Steve

More progress pics :)

The stock kit wheels and tires are only fair in quality, but the tire most specifically incorrect size being to large overall diameter, and bald sidewall
Originally donor tires from a C5 Corvette kit were considered, but though they had sidewall markings (Goodyear) they were to small in overall diameter

1476137_546419828785064_1216359788_n.jpg

Stock kit wheels are de-chromed in oven cleaner

1469882_546432548783792_1297395889_n.jpg

Stock kit wheels trimmed of ribs around outer drum surface, and sanded smooth, without distortion of front lip

1469882_546432545450459_1712910194_n.jpg

The stock kit wheels have noticeably rounded spokes, and center lug area closed in, so extra material removed to square shoulders of spokes and open center lug dish area

1476137_546419832118397_1359011912_n.jpg

To correct the tire issue, entirely new digitally designed tires developed (thank you Joseph), making a production correct Goodyear band tire, correct tread design, and correct dimensions (using the stock kit wheels dimensions I.D.)

1476137_546419842118396_461001974_n.jpg

First 3D print of the digitally designed tires, showing good tread and sidewall markings

1476137_546419838785063_1947721512_n.jpg

Final print of the digitally designed tires ready for use, shown compared to stock kit wheel & tire set

1476137_546419835451730_896725540_n.jpg

Painted of final version tire and modified wheels, ready for use

1486745_546420358785011_471197872_n.jpg

For realism, tires painted with flat black in tread blocks and inner wall, and satin black on outer sidewalls (simulates detailed/cleaned tires)

More progress pics! :)

Door is going to stay in an open position for display purposes, but the inner door frame & hinges are scratch built using photo etch bars & hard wire rod, to look like the production car, once all is painted, then the door pins allow it to slide down directly into pivots

1426745_544168295676884_139221125_n.jpg

Door hung in test fit, showing proper appearance, and articulation into the front fender

1426745_544168285676885_1892191424_n.jpg

Engine hood is modified with photo etch pivot bars also, bent and modified to sit flush, hard wire bent and placed inset of fender underside to connect and articulate hood, and pivot point(s) located as far back as possible, so hood opens up and clear of the cowl, while giving a much smaller volume than the plastic kit hinge arms

Underside of hood given some scratch built detailing around edges to simulate bracing, and under hood covering simulated using layers of tape, cut to shapes and until thickness enough for appearance, later will be painted in flat black, and glued to under side position of finished painted hood

1426745_544168289010218_699039334_n.jpg

With all priming and wet sanding done, final coat of fine white primer is sprayed & wet sanded (to 2K grit), then first coat of acrylic lacquer applied

1426745_544168299010217_1469375546_n.jpg

After first lacquer coat, each piece wet sanded (starting from 1K grit and up), then washed thoroughly and let to dry

Back to the engine bay, stock plastic parts being modified or enhanced for realism, like the coolant hose assemblies, made of thicker gauge line, and formed to shape, cast splitter housing enhanced with sensors and further detail

1454737_544170649009982_165393148_n.jpg

Test fit of upper coolant hose parts

1454737_544170655676648_1891746474_n.jpg

Basic engine being put together and modified for detail, styrene added to front of cylinder heads, so to fill in under valve covers properly, styrene strips scratch built and added over fuel injector ports, to simulate production car

1454737_544170659009981_1232786726_n.jpg

Stock plastic accessory belt parts modified, my method is to mark the face with ink, then scrape away the inside surfaces to thin the belt portions, cutting the inside corners alongside pulleys, leaving the backside of the belts slightly thicker for strength, but the face edge as thin possible for realistic appearance

1469861_544172682343112_1453606596_n.jpg

Upper coolant hose towers modified on engine block, adding second hose ports, for realism
After the first accessory belt part modified, painted and installed, the secondary belt part is also modified, painted and installed, because the lower half of these parts will be fairly hidden down in between the engine & radiator shroud, there isn't as much modification required

More progress pics! :)

Engine supercharger assembly and air box also modified and enhanced, sensors added, and ultra-thin copper wire used to create sensor wire leads, which once painted will integrate into chassis wire harness

1454737_544170652343315_522975236_n.jpg

1469861_544172692343111_368685114_n.jpg

Engine wiring harness(s) constructed, using thin wires, twisted around each other to hold shape, and provide braches like individual fuel injector plug ends

1469861_544172679009779_1259167088_n.jpg

With all individual parts painted, using various semi-gloss and flat paints + clears, to give complexity of surface colourings, are all assembled

Comparison of some stock plastic kit parts, to finished modified and painted assembly

1471297_544176185676095_283013016_n.jpg

Power steering fluid housing constructed, of clear plastic tube body, sanded for frosted white semi-transparent appearance, with fluid paint to be added after to hollowed interior for realism & semi-visible through frosted container
Lid portion cut off & new part scratch built, using photo etch turn cap, and ultra-fine copper wire as cap leash, to be painted and attached to reservoir after attached to engine front

1471297_544176189009428_1190491839_n.jpg

Coolant reservoirs modified, opaque lid sections cut from bottom, and new bottom portions constructed of clear plastic & clear resin filler, until correct shape, and sanded for semi-transparent appearance, with orange fluid paint added after to hollowed interior for realism & semi-visible through frosted container

1474436_544180522342328_1375334731_n.jpg

Assembled engine & other ancillary detailed components finished and set in dust free container for later final assembly into chassis
