Posted 16 May 2007 - 05:23 PM

I was cleaning out my garage and found some fixtures that reminded me of yet another unfinished project that I need to finish.

The Cox Gurney Stocker has always been one of my favorite slot cars. It really has "The Look". Apparently lots of others agree because the price of an original piece in good shape was and still is quite high.

Almost 20 years ago I was a struggling apprentice machinist. I had access to machine tools and materials but very little extra money. But I was jonesing for Gurney Stocker. What to do? Why, make one from scratch of course! I borrowed an original from a friend for reference under the condition that I would make an extra chassis for him.

The first fixtures are simple aluminum blocks that I sandwiched six stacked-up pieces of 1/32" thick brass sheets between 1/8" thick brass backing plates. These were then drilled and end-milled into a flat pattern of the front and rear motor mounts. Here are the "consumed" fixtures and backing plates:

Posted Image

I machined another aluminum block the correct width to shape the flat patterns into motor mounts. Here is a left over set:

Posted Image

A steel tool was machined to form the "hump" in the drop arm gusset by placing a sheet of 1/32" brass in the tool and compressing the tool in a press:

Posted Image

The body mounts were also 1/32” sheets sandwiched between thick backing plates and drilled and milled. Here are the "consumed" backing plates:

Posted Image

The rest of the chassis is various sizes of brass tube that all needs to be soldered up to the brackets in the correct position and alignment. Another hunk of aluminum and a zillion dowel pins later and I had a soldering fixture:

Posted Image

Here's what my finished repop chassis looks like in the fixture. It's got some light corrosion here and there so I'll need to toss it in the tumbler for a few hours:

Posted Image

This is one of my more elaborate jigs I used to bend the main rails . . . hey, whatever works!

Posted Image

The end of the main rails had to be flattened out and bent around the axle tube with some round jaw needle nose pliers:

Posted Image

The drop arm tube was split down the middle with a cut-off wheel, flattened, and bent around the pivot tube with pliers:

Posted Image

A close up:

Posted Image

The drop arm gusset was cut with a Dremel cut off wheel and a hook bent with pliers for the guide's self-centering rubber band:

Posted Image

I added a screw hole in the front motor bracket to help secure the motor:

Posted Image

The finished chassis:

Posted Image

Posted Image

The front wheels are unique to the Gurney (I think!). I lathe-turned a pair of repops from aluminum bar stock:

Posted Image

The rest of the parts were picked up at EJ's Hobbies and REH (remember this was a long time ago!). My friend that loaned me the chassis kicked down the front axle and knock-offs. For a body I started with an old AMT 3 in 1 model kit. To get the little slots that the body mount tabs fit into cut in the right place I made another fixture. Hey, I was an apprentice machinist . . . I machined everything! Here's the body clamped into the fixture with the rear wheel wells located against a stop:

Posted Image

This is the resulting slot and the 1/32" diameter end mill I used to cut it. The cutter radius in the corners was removed with a jewelers file:

Posted Image

While the body was in the fixture I machined this cut-out for the quick-fill gas cap to go in:

Posted Image

I scraped all the molded in trim off the street car body until I came upon the windshield wipers the Cox car doesn't have. I could remove the wipers but the little grill vents wouldn't be "Korrect". What remains of the wipers would be blocking the vents. Maybe that's just how it has to be?

Posted Image

ARG! That's when I threw the project into a "Captain Rick Official Slot Car Storage Box" and moved on to something else. All the mechanical stuff was done and the modeling and painting remained. For me that meant the thrill was gone and I bailed.

Fast forward to today. I saw the beautiful Gurney Stockers on Slotblog done by Jarius Watson and Chris Clark. Then I happen upon a resin repop interior kit on eBay. I contacted Jarius and he's agreed to apply his magic to the modeling part of the project. Thank you, Jairus.

I love it when a plan comes together! More to come . . .

Gee! Rick, you make me sweat just by looking at the pictures . . . please give me a call, I will GIVE you an NOS chassis, for God's sake! :lol:
Incredible and splendid work. :)

It is actually possible to remove the wipers, and carve out the vent slots with an X-Acto knife. Go ahead, ask me how I know this. :shock: :x :wall: :roll:

Actually, removing the 427 logos, while leaving the body spears intact was probably at least as hard, if not harder.

The red roof turned blue from emotion or was there one painted like that driven by Turnis Curter? :)

Don't know the driver, but, there was indeed a blue roofed Galaxie. I think Dan even drove it at least once in this color combo. :shock:

Beautiful work and that attitude is worth its weight in gold. :clap: We need a few million more people thinking along those lines in this country.

What's more, it got you the prize from Dokk and you have a Gurney chassis jig and tooling worth $$$.

Nice job, Rick! Since you have all the jigs, when are you firing up the production line? :)

Holy Smokes! No, I'm not making any more of these :shock: . There is lots of hand and machine work involved . . . and I'm a lot older now ;) (and hopefully wiser!). The only easy and really fun part was soldering up everything in the jig. That jig worked really well.

Slitting a piece of 1/8" tube down the middle, flattening the pieces, and wrapping them around a 7/32" tube to form the drop arm is something to look back on with satisfaction and hopefully never to repeat :lol: . But I wouldn’t trade this chassis for a dozen Cox chassis. :) .

Hey, Dokk, could you help out with the Korrect driver figure ? :mrgreen: :?: :) It's a Cox #14025.

I hope you finish this, Rick - The chassis looks amazing !

Excellent post - more please. :)

Hey, Dokk, could you help out with the Korrect driver figure? It's a Cox #14025.

Sure thing Rick. But in fact it is exactly the same as the regular Chaparral/Dino driver, only with amputated feet to fit inside the cockpit . . .:)

I think I have sheets of the Cox "stock car" waterslide decals available if anyone is tackling this project.

I am sure we can work out a reasonable price if anyone is interested.

Please, Rick,
Forgive me for intruding on your outstanding thread (great build, great pictures as usual!!!) but, in a shameless display of vanity, I wanted to show off a poor man's Dan Gurney's (a fake one, can you believe it!).
Here is my (original copy) AMT Professor Motor Fairlane kit made up by Swissracer:

The chassis was tuned by Bruno Novarese, so it could be decently raced even by me in Turin's 18th Vintage meeting which took place last week:

Thanks, Philippe. :) I'll take care of that Chaparral/Dino driver's feet. :shock: :mrgreen: . I'll PM you my mailing address and thank you again.

Forgive me for intruding . . .

Hi Edo, thanks for sharing your neat car. I say everyone, show us your Gurney Stockers here!

Here's the link to Chris Clark's beauty: Gurney Stocker.

I can't find the post that shows the Jairus restoration or I'd put it here, too. 8) .

I'll get the running gear all polished up and assembled. I'll next round up all the bits and pieces I have for the body and interior and post pictures. I'm hoping between the Dokk's driver figure, resin repop interior, and the race car parts in the vintage AMT 3 in 1 model kit, Jarius can make it work. 8)

Thanks to everyone for your support. :up:

Gurney, the only driver that Jimmy Clark ever worried about . . .

Cool, stockers all the way around!

. . . Seriously, Edo, do you think I could miss them? :love: I must have them.

I would have much to say about those kind of comments but out of respect for the thread's subject I won't comment.
Rick, may you forgive those who don't know what they are talking about!
