Skunkworks Model Shop - '67 Impala SS
Permalink  
 


Due to our little Covid-19 microbe buddy, work for me pretty much came to a standstill. My profession is considered "essential", but when your customer locations are shut down it doesn't matter.

Prior to Apr 6, my hours were dwindling down, and I was spending some free time at the model bench. Yesterday (April 6) I went on furlough... at least 2 weeks, maybe more. So, I'm able to devote a lot of time to this project.

My plans for this project is to build my 1st "real" diorama. I'm envisioning a garage scene, with a restored frame/powertrain off to one side, and a ratty/rusted (but solid) body off to the other side. Karl's "BisQwik" car was part of the inspiration... too bad the kit is a '67!

Enough yapping

This is what I'm after

Body01.jpg

Starting to scribe "cut lines" into areas that will be removed. I've got an assortment of dental picks that have been reground/shaped, and if you keep going over the same line...

Body02.jpg

The piece will eventually be thin enough to cut with a blade or just break free.

Body03.jpg

Same thing with the front door gap/seam. I repeatedly scribed it until it was nearly through, then hit the backside with a Dremel & sanding drum to separate it.

The cuts along the cowl and windshield were done with a razor saw, scribing, and a sharp blade (scary).

Body04.jpg

Body05.jpg

Now I had to create the ends of the firewall. They're not part of the kit (as they'd never be seen). The interior "tub" makes up the lower 1/3 of the firewall, and a separate piece is the firewall proper - and these parts mate to the cowl vent area of the body at final assembly. So whatever I do needs to be attached to the interior tub to be removeable. The firewall was glued to the interior tub, and the whole thing was taped in place. I use Post-It notes to make templates for sheet plastic. They work great, and the sticky side can be used to your advantage.

Body06.jpg

The paper template transferred to .003 sheet styrene. A little pre-bend shaping, and then glued to the firewall. The upper flat "tabs" are just butted under the cowl vent, but glued to the firewall.

Body07.jpg

Some side filler pieces were cut to close the gap on the ends. All the pieces will bonded and seams filled with my proprietary DDSSAPSAMBF mixture, then shaped and sanded.

(That's Doctor Duck's Super Secret All Purpose Sauce And Model Body Filler - a mixture of thick Super Glue and talcum powder).

During a model build, you can have several phases going on at the same time - because you're literally "waiting for paint to dry"!

(Another essential tool(s) is a TV, DVD player, and box-sets of your favorite shows razz)

While the firewall pieces were setting up, I was giving thought to the front wheelhouses. In the original form of the kit, the wheelhouses didn't need to go all the way out to the fenders... you wouldn't see it, so they didn't do it.

With the nose/front end of the car off, it's a different story. How to create/extend the plastic 1/2 wheelhouses to the fender. hmmmmm. Trying to cut/shape/bend sheet stock proved to be impossible and impractical. Enter my fall-back DDSSAPSAMBF and some aluminum foil.

Modellers use a technique call "foiling" to recreate the intricate chrome trim on cars. Two ways to do it - use a commercially available product such as "Bare Metal Foil", or a bonding agent and regular 'ol Reynolds Wrap.

Using Bare Metal Foil product (BMF) has drawbacks. It's expensive, comes in a 6 x 11 sheet, and the entire sheet has "sticky stuff" on the backside (it comes on a release-paper backer sheet). It sticks where you don't want it to, and after applying and burnishing down you have to cut along the edge and remove the waste. 

"Micro-Scale Industries" markets an adhesive product (liquid in a bottle) that you can brush on exactly where needed, then apply your own foil. There's very little waste, and the foil is only stuck down where you applied the glue. I also use the cheapest "Dollar Store/Dollar General" aluminum foil I can find. It's very thin and lousy for cooking, but great for model car trim!

Body08.jpg

Using MicroScale adhesive, I painted the edges of the plastic wheelhouses, and the edge of the fender. Then some foil strips were coaxed into place, roughly curving and shaping the remainder of the wheelhouse.

Body09.jpg

Then several batches of DDSSAPSAMBF (I need a shorter acronym) were mixed up, and buttered into the area. Once set up and hardened I can go back and contour this with the Dremel and shape it to blend to the plastic wheelhouse and fender.

As mentioned, there were other things going on. As the fenders were drying, I'd started on detailing the engine components.

Engine01.jpg

This kit has the Big Block, but with a late-model EFI setup on it, and HEI distributor with vacuum advance (??). The distributor was drilled for plug wires, a retainer cap/ring made from .003 sheet, and it was threaded with scale appropriate plug wires. (That is a toothpick holding the parts... just to give you a size reference).

Engine02.jpg

Another job was to go OCD on the alternator, crankshaft, and water pump pulley system. A company called Detail Master markets some really cool laser cut stuff for hyper-detailing. It's one of their fan blade pieces under a custom pulley I made.

pulleys01.jpg

One of the things that's always torqued me was the clunky and not-to-scale look of the combination crank/WP/alternator/belt "thing" that every model car kit engine has! Granted, it's an easy & cost effective way to represent a difficult bunch of parts, but it's ugly.

Now that I've got my mini Sherline lathe setup, I can finally make my own parts. Taking measurements from the plastic pieces, I chucked up a piece of 1/4" aluminum rod-stock, and re-created the three pulleys.

pulleys02.jpg

They were painted with semi-gloss black, and a gold mix (haven't found a good simulated cadmium color...) for the alternator.

Engine03.jpg

The engine block, bellhousing, and transmission were painted Chevy Orange and Flat Aluminum. Plug wire holes drilled in the heads, and totally scratch-built shifter linkage & arms on the transmission.

Wow, my head hurts just thinking about the patience and skill required to do this. I'll just go out in the shop and mount new summer tires for the wife's car.

New acronym for Doctor Ducks...how about CF, short for another Karl inspired term...chemical filler.

Remember, Craftsman use chemical filler, the other guys use "Bondo"

beers

John, I am incapable of having the patience to do most of the stuff you do!

Really neat effort, have fun!!!

Now thats what I’m talking about. Can’t wait to see the body on sawhorses. Keep leaking the intel.
