Hi

And the .8 ohm reading is "correct" for a 30s 65 turn.

Yes they are pretty Rick, no question.

Bah humbug...it's all well past the point where it even matters

First time in a week I've got home before 7 and you lot're already raggin' on me? <snif> Where's that inhaler...

Well, there's that point in our models, you're right. What I'm stressing is knowing where that point is, and how well your tools will deliver up to & past it. It's precisely the equivalent of getting in your new car & "Let's see what this baby'll do!"--you do a shakedown, learn the limits of both machine & operator, so on those occasions when you really need it you'll know what you got & what you can use. That's how you build with confidence, and the more you think on the level of every related thousandth (even when you can't do anything about some of 'em) the better the stackup of errors will be on the finished job.

Hmmmmmm..........this all sounds familiar. Duffy are you sure you're not really named Otto Shaffer ? He's the German Journeyman I trained under for the first 3 months of my apprenticeship .

[Hworth08]

Well Rick, I don't think the motors are that pretty. Naw, even better, they're TUFF lookin'!

Sort of funny now but back when I was a serious (though too young) racer my motors were about the same speed as the two Rick just put together. Technology.

I'm not a real German; I only play one on Slotblog...No, mostly by name, I'm more Brit genes than anything.

My first car ('70) was a '52 Beetle, bought for $150 from Leo's Foreign Cars in Orange County; split rear window & all--but, Leo, he was a real German; crewed for Hans Stuck & everything. I'll never forget him first showing the car: "Gooood, rrreliable trrransporrrtation, youvull like the carrr; A little rrrough, got gearrrbox like old whorrre" (illustrating this last by miming stirring with a broomstick in a bucket) but goood trrransporrrtation..."

Agreed, and that's "101" for about any trade I can think of, except with carpentry we don't go past a "heavy" 1/32" because wood just doesn't "roll that way". It even applies to target shooting...you wanna get good, you don't shoot at beer cans, you shoot at pencils and then dots. Still, when you get to the point where an armature and the lathe it's chucked-in are reading .001" runout, it's looong past "Miller Time".

PS...yeppers Rick, the motors have all kinds of shiny niceness. I still think they'll run as well as any Mabuchi EVER has!

[Duffy]

Can't resist this--when I was doing Crazy Wave Boatworks, the joke in the industry was "Carpenters build to the nearest 1/8"; cabinet makers build to the nearest 1/32"....boatbuilders build to the nearest--boat."

Duffy

[havlicek]

Well sort of Duffy...carpenters worth a damn build to the nearest 1/16" and cabinet makers to the nearest 1/32" and the either goes "heavy" or "light" if they really care and take pride in their work

[endbelldrive]

Now this discussion is all well and good and very informative but I think we're all missing the real point here......"AIN'T THEY PURDY!"

Mongo says, "motor purdy"... "fire hot"...

[Duffy]

Actually it was a joke, aimed not at all woodworkers but at modern boatbuilding & the jealousy and envy that passed as "cameraderie" among pro dabblers at the time.

My father was a cabinet maker; he taught me to tune up my planes to get translucent curls, then to fit boards within a single plane's pass. Again, a matter of knowing your tools, not a functional industry-standard.

Mongo, motor hot, too... go much fast!

Not to worry guys, I knows my tools....

HEAVY DUTY C-CLAMP

[dc-65x]

The roller is ready for the body. I’ve got both motors spinning CCW, front and rear wheels driving the car forward and the faster of the two motors up front….wheeew!





Lots-O-wires running all over! The lead wire retainers up front worked out great. The guide turns free and is self centering.

So, was heat shrink tube available in 1966? I don’t recall seeing it used on slot cars but could it have been? I sure like the stuff .

Bottoms up:



Time to mount and finish the body…………ONWARD!

[tonyp]

Interesting. Looks like a car now with the motors in it. Very nice.......

[TSR]

Guide setup is critical, a fine balance between contact and traction. The issue I can see is that the front wheel on the outside of a curve will have a tendency to want to pull the car out of the slot, a characteristic of the Russkit model when pushed... so for the Russkit model, the less front traction by setting the guide lower with guide washers, the better the car runs! The counteracting factor is of course the weight of the front motor that reduces understeer.

[Hworth08]

Beautiful chassis!! All the magazines would have wanted to feature that car in the day!

[endbelldrive]

Kool car! Whaddya think...maybe going up and down a tooth or two on the front crown gear could give you some funky handling characteristics.

[Regis4446]

Fabulous work

[dc-65x]

Thanks guys, I'm happy with the way it turned out. I just hope I can get it to be as much fun to drive as the 4WD Novi I showed earlier.

Whaddya think... maybe going up and down a tooth or two on the front crown gear could give you some funky handling characteristics.

To start out, I've got a faster sounding motor in the front and the current gearing is set to balance the different front and rear tire diameters. I will bring some extra gear sizes to the track to fiddle with .

Can't wait to run it .

[Pablo]

When is the track test ?

[dc-65x]

Hi Pablo,

The track test at my home "Dawn of Time Raceway" is imminent. The real test at Eddie's Slot Car World should be coming up soon. I want to get a few other cars ready to test there before I make the long trek.

In the mean time, the body is trimmed and mounted....with only a few extra pin holes to hide ......oh well, hide them I will





I cut the bottom of the seat off the interior to clear the two motors. I added a model car wheel to the spare tire and cut a hole in the rear window for the gas cap. The body and interior are ready for paint:



This is the point I usually loose interest and start another project . Hmmmm....start another project . That sounds like fun . I know, I'll say I'm not going to paint this car until I test it first. Yeah yeah sure sure, that's it I need to test it first .

New project time!

[Horsepower]

The projects done and I STILL haven't found that Tom Malone article. I'm on magazine number 28 as of now.

[dc-65x]

Thanks for your efforts Gary. The project has a ways to go yet. I still have paint and detailing. Then there's tuning at Eddie's .

[dc-65x]

GOOD NEWS!.........for me . My friend and artist Jairus Watson has agreed to turn his talents loose on my Iso Grifo. WEEEEEEEEEEEEE!!!!!!!!!!!! Now I can start building another car .

First I had to get some details on the interior made up before paint. I ditched the plastic Russkit gas cap. It is very nice but I wanted to make one up like we did in the day:



A little soldering:



A little cutting, filing and polishing:



And we have an old school gas cap. It doesn't look super scale realistic. It does look like it belongs on a 1966 scratch built slot car as I remember them .

Here's a shift lever, knob and boot made from a wheel retainer, pin and pin tube:



A roll bar from aluminum rod and a wire wheel from a model kit and it's ready for paint:



I'll "ZOOM" it your way tomorrow Jairus and THANKS!

[Tex]

Those little details make all the difference! Schweet!
