Rick use my turbo drops. It will make that thing fly...

...You can squeeze a TURBO???.....

Hi

Duffy, just because you are newly married, I am guessing you have lost the grip needed to do this!

It's my professional opinion that the equipment needed to apply pressure to a standard trumpet, sufficient to render usable quantities of the resultant oil, is beyond most of us hobbyists.

I hear ya, dood. Same with Nauga's; do you know how MANY Nauga's you have to catch/kill to make one decent Naugahyde? Believe me, you don't wanna know!

Poor Rick's excellent post seem to be caught in a continious loop of drift. And it's spreading.

[Duffy]

You can't always expect us to be sane, dull, and dry. Especially when our hands are dripping with turbo viscera.

Hey guys I like all appreciate all these kind of fun comments. It keeps the thread alive. I only have time to build on the weekends.......two days to go

[dc-65x]

I modified these motor brackets in the upper right.....



like so.......



Now the motor can be slid out of the chassis:



I also "Duffied" my rear axle tube. Although I bet Sir Duffster will cringe at my setup :



It turned out great though. The guys in the 60's magazines were always drilling holes in things. I think it looks very period Korrect:



So it's jigged up and ready to go but.....



.....if I could just stay on task . I got an idea for the motor to use in a "Lost Cause" Chaparral I body that John "The Viceroy of Vacuum" Dilworth made for me.

Must stay on task. Must stay on task. Maybe I could just build the motor for the Chappy....

Ohhhhhhh man oh man, did you ever get Lucky. Y'know that PINGing sound, the one when you clamp tubing the wrong way in a vise and try to machine it? Yah, that sound. You didn't hear it, huh? Try this again. You'll hear it.

This is such fun to watch. I GOT one o those chasses, and a Strommie Defribrillator to go on it, AND a big nasty VANWALL to wrap over the top like a green tortilla!! I WANNA DO THIS CAR!!...right after I finish a nice tame little 1/32 Ferrari P3...

Yes, I have to admit I know the sound . But hey, it's not as bad as the guy at a drill press trying to drill an 1 3/8" hole in a hand held, foot square piece of sheet metal with a blacksmith drill . I have to admit I left the shop so as not to witness the potential carnage.

Anywho, I made up a bunch of pieces, parts:



Looks like an old angle winder chassis kit .

I got all 8 main rails bent, trimmed to length and deburred. I think it looks so much cleaner to have all the rails deburred where they attach to the front axle tube instead of just cutting them off with a Dremel.

4 rails:



8 rails:

Superb, Rick. Can't wait to see it 'dressed'.

Inspiring no

I think my whole youth just flashed before my eyes, including a midnight double bill of "It's a Mad, Mad, Mad, Mad World" and "What's new Pussycat?", with my unrequited high-school crush by my side...

Maybe you should change that chassis design Captain Rick....

[Hworth08]

IIRC, there's a treasure buried under the W palm trees. Maybe a stash of slot parts from a '60s bankrupt slot company?

Oh yeah... fear the big "Doub'yuh"!

Only if he puts a red Cord convertible over it. ( "...a red SPORTS CAR??" Jeez, somebody should've slipped Woody Allen a copy of R&T...)

My "inspiration" for the chassis came from a 1965 article by Mike Morrissey:



Mikes rails are very slightly splayed:



I tried to R&C morph it into what it might have looked like at the end of the 1966 season with the heavier cars. Or I might just be "searching for the dolphin in the sea"......... .

[Tex]

Looks good, Rick; straightforward and functional.

[Prof. Fate]

Hi

Back then, I saw a lot of variants of "splayed" rails and other similar approaches. One related to it was that of having a narrower REAR track. What the word was was that somehow this would work better when accelerating out of the corner. Cars then with the tires and surfaces then often had troubles "hooking up" and you would see them wiggling from side to side down the straight. The discussion was that this movement ate energy, and splayed rails and narrow rear tracks were both an effort to straighten out the car.

For me, tried once and then decided on the Colin Chapman rule "just tell me how wide it is allowed".

Hi Rocky,

At my local SoCal raceway (Grand Prix Raceway) in late 65 to early 66 the hot cars were lightweight GP’s with rewound 16D Mabuchi’s. I distinctly remember we had power but lacked traction. The tracks were a small oval with a gloss surface we tried to keep the nub’s on and a flat road course with a flat black surface.

I’m not sure if we were still running “Germans” or the new foam tires like VC’s or Tiny’s. But, to gain more traction in the turns (and probably stop the fish tailing you talked about down the straights) we would narrow up the rear track maybe a half inch narrower than the front. I didn’t like doing this as the cars looked stupid but if you wanted to keep up you had to.

[tonyp]

Same out here in NJ. Later on I always built my 1/12th RC cars that way. More forward bite exiting the turns.. No one ever figured it out..

[dc-65x]

Hi Tony,

I wondered if it had something to do with the outside rear tire having a greater distance to travel around a turn than the inside rear ? Maybe the less that variation is the more bite? Or maybe it’s just slot car black magic!

[Hworth08]

Check the old drag racers, always the rear track about as narrow as they could get it.

We did the same with pulling trucks and tractors.

I can't remember the exact reason a narrow track goes straighter but it has to do with the lever principal. The closer the tires are together the less force the tire that is gripping more has to push the vechile sideways.

And that may qualify as the worst way to explain it in history!

Way off topic but when I saw the reference to the "Dolphin in the sea" this immediately came to mind. One of my favorite movies of my youth. Check out about 1 minute in. VA-VA-VOOM
