Just a "fun car" - no rules.

Which is about as true to the tradition as it gets!  Build on!

No rules cars are just the best

Well, you can't have a 6" wheel-to-wheel width, you ought to have a 1/16" chassis clearance front & rear.That's an old body, bet it came from AL. Paint it silver & white with fluorescent pink numbers, or send it to me & i will.  

 

A couple pre-build questions.

 

1.) Are you actually going to use that F1 interior with the McLaren Can Am body?

 

2.) Why do manufacturers put 4 endbell mounting holes in cans?    In case you strip 2 out?

 

Build on!

"No Rules" 60s style. I love it.

Hmmm, Bill, should I use an ugly F1 driver and paint it myself, or open up a drawer full of painted Noose interiors and pick one ?

That was "Run what ya brung" racing days days. If you got blown away some week, you came back with something faster next time. Anybody would build themselves a retro car & power it with a D or C-can. I'm betting this one will be an anglewinder.

Here's the answer to your dilema. Spray the body, including the windshield, with one color of paint. Cut  a round hole, about the size of a penny, wherever you want the interior to be.  Then you just have to paint the driver's helmet & stick it through the hole. See, simple yuh?

I love hearing those stories of racers building/rebuilding chassis and winding armatures in their hotel rooms back in the day. 

 

If you need a spur gear I have those Cobras you liked so much

[Pablo]

Here are the specs and history of the "gear-stripping powerful" motor:

24/26 Havlicek arm, Mura can/endbell, BB's on both ends, fully blueprinted, airgap 15 thou, modern "C" magnets, shunts, insulators, and buss bars.

I originally built it for my Batmobile.

 

Here is what I posted after track test #1:

"This motor absolutely blows away anything I've ever built - too much power - I didn't think I would ever say that.

The Havlicek/Pablo/Mura motor has been cleaned, inspected, tested, labeled and bagged. 

She is going to take a long nap in the vintage motor box of horrors until I build a lead sled chassis for it. 

Also need to order a bottle of Koford Heavy"

 

The time for this motor has come. The Batmobile weighed 135 grams, wonder what weight I should shoot for on this one ?

[Pablo]

I haven't looked at my gear box of horrors yet, Sam, but I guarantee you I won't be using one of those doggone Cobra spurs

The teeth can be cut off the hub and they make good jig axle gizmos

[Bill from NH]

I ran Cobra spur gears on my weekly race cars from 1970-75 because they ran truer than the Cox. So did most of the other  racers at Modelville Hobbies. We didn't experience any meshing problems with them. I'm wondering if today's pinions are using a different tooth profile than those of that era.

McLaren decals and a Jairus Watson painted driver

 

Cobra lead wire, .032 Bat Pans, 1 1/4" wide drop arm, Jet flag, Parma brass clips, Koford flag spacers,

Prime braid, Classic weight, Koford big head body pins, Koford rear axle, VXB non-shielded ball bearings, JK D4 donuts.

Plus, 1972 Aguirre front wheels, Steve Okeefe rear wheels, and 41T 64P factory sleeved 3/32 Faas spur gear, all gifted by Rick Thigpen

 

These 3 bad boys are going in the tumbler right now before they infect my other parts !!

[Pablo]

As long as I'm tumblin' stuff, might as well throw in some more brass laundry

 

[Pablo]

This time I got smart and soaked ALL my ball bearings in acetone, instead of one pair at a time

[Bill from NH]

Two of those droparms look to be Parma's, a Phaze III, a Cobra, & a REHCO.

[SlotStox#53]

Certainly alot of dirty laundry you got there Pablo ! All ready for plenty of no rule cars

Maybe even a few recreations

[Pablo]

Am I the only one who ensures my anglewinder motors are centered left/right to balance the weight ?

Before I can set up my jig, I need to know exactly where the motor will sit.

 

First I put the gears and jig motor in place exactly as they will end up with the "real" motor, and measure the angle.

In this case, looks like about 6.5 degrees

 

Then, as a visual reference and a balance checker, I bend a piece of wire at that angle

 

Photo doesn't show it but the centerline balance point more or less runs right through the middle of the (EB side) can hole

 

Now with that hole on the centerline of the jig with the gears in place at 6.5 degrees, I know it's balanced and it's right where I want it.

Knowledge is power

BB's out of the acetone bath, rinsed in lighter fluid, then sealed wet with WD-40. Except these 2 didn't get put away - they are soaking in Mobil 1

[SlotStox#53]

How long do you soak the BB's in acetone for Pablo?

[Pablo]

There is no science in it, Paul.

If you let them soak too long, the acetone evaporates and you'll never know where the factory grease ended up.

Not long enough, and the grease remains.

 

If it was possible to know exactly what grease was installed, that would be another story.

In this case, I didn't see a lot of dissolved grease. What I did see was different types and sizes of particulate matter.

 

I heard of an R/C guy in Japan who soaks his BB's in lighter fluid for 30 days.

On any given day, a good driver with a dirty car and misaligned worn out oilites could out-run me.

 

Was that too much info, Paul ?

[Zippity]

What is the purpose of soaking new BB in Acetone?

[Bill from NH]

You can cut the cleaning time way down if you use an ultrasonic cleaner. The $10 denture cleaners at Walmart may work too. Fill the cleaner tank with water, stick your bearings & favorite cleaning solution in a clean small glass jar, stick the jar in the cleaner's tank, & turn the unit on. Unshielded bearings will clean quicker than shielded ones. 

[Pablo]

Zippity, as a precautionary measure to remove any protective greases installed at the factory.

How do I know this stuff ? Because I actually read Slotblog, instead of just clicking on "View New Content"

 

Faas spur hub needed some narrowing. In the process, I shined it up with 2,000 grit wet/dry sandpaper

 

[Bill from NH]

Hey, I use [View New Content] & I know that stuff. 

 

How much has to come off the Fass hub? Enough to keep the setscrew location in place? Narrow up two gears so you'll have a spare, just in case. My Unimat is available.
