 It tastes great, too !

Tastes great, less filling

She passed the drivetrain test 100% perfect, sounds real strong, perfect gear mesh, no vibration.

Motor is soldered in 3 locations.

Mmmm shiny brass, anglewinder chassis with an Havlicek motor........ Heaven

Nice! Is that a Cox or a Cobra spur gear? What's the purpose of the big hole in the underside of the rear axle tube? Was it someone's attempt to allow oiling of the rear bearings & axle?

[tonyp]

That drop arm remind me of some cars jerry Brady built around the time of the Cobra Mura race that were suppose to revolutionize chassis design. They had a wide drop arm like that with the center section running inside the drop arm.

[tonyp]

Needless to say they were toads.

[Pablo]

Bill, the axle tube hole permits oils and fluids to escape, and allows for precise oiling and cleaning of the ball bearings.

It's big enough to allow a bent pipe cleaner to clean the BB's.  Also big enough to allow the ceramic media of the tumbling process to enter and exit at will.  I've see the insides of vintage axle tubes that were closed up tight after 40 years,and it ain't pretty 

 

The spur is a 34T Cox.  I don't know about the original genuine Cobra spurs back in the day, but the ones that are circulating today be they genuine or not, are non-meshing junk.  If you doubt that, look at all the Cobra spurs for sale on eBay constantly for about $3 apiece.  Nobody wants 'em.  Try searching for a 34T Cox set screw like that one; not so easy.  Been there done that got the TShirt and the crying towel.

 

Tony, no doubt they were toads or tilting piles, if the motors were positioned off center of balance point like this one was originally. That's been fixed on this one

I've seen Cukras & Schmid slot & drill holes for bearing maintenance on inline chassis, but I've not seen it done on anglewinders before. I know I've never done it. It must be my motor cutouts in the rear tube that served the same purpose.<G>

 

In the day, I used both Cox & Cobra spurs on my weekly Grp. 12 race car without problems, from 1970-75. Pinions were 7.8. & 9T brass ones from REHCO.  I found more Cox to be out of round or wobble than the Cobras back then. These conditions were both caused by attaching the gear hubs half-a$$ed. I don't know whether today's Cox & Cobra gears are leftover originals or if they're repros made by someone such as REHCO or another company. For open class cars during the same period, I used the Fass 64 pitch bronze spurs & steel pinions.

All done, ready for track test this Saturday at The Dungeon.

In the end, a Jet Flag worked after all, but I had to find my thinnest one

Junk test body is mounted and she is ready to go.

Very clean build Pablo. It looks like a winner! I saved enough of its photos if I ever get inspired enough to build my own version.  I've had this weird assymetrical design on paper for 5 or 6 years. I probably ought to build it first.

[SlotStox#53]

Shiny brass + blue sponge + red Havlicek/Mura = pure slot car heaven

That is really sweet Pablo, here's to a fast successful track test

[Pablo]

Bill, I don't recommend ever using a drop arm that wide, it creates a whole bunch of design problems.

If "Steve" ever surfaces, I'm sure he will agree 

[Bill from NH]

I'd have to hand-make those brass chassis parts if I ever decided to make a repro of that chassis.   Not totally out of the question, I have some .050 sheet stock. Does this thread contain the half rail & main rail piano wire sizes? If "Steve" ever surfaced, he'd be quite a popular guy. I wonder what country he'd surface in?

No.   PM me for an answer 

[Peter Horvath]

Beautiful.

 

I will weep if I wreck this one...

As will Pablo, I'm sure

I would say, "It's time to learn how to build brass/wire vintage chassis." if I bend this one.

 

Peter, do you know where, when, or under what circumstances, you got this particular chassis? Was it an ebay sale? from a friend? from a local estate sale? some other means?  I own a couple motors I have no idea how I acquired them, but all my old chassis. I know where they originated.

[Pablo]

"I will weep if I wreck this one....."

As will Pablo, I'm sure  

 

Nope.  There is no crying here at The Wolcott Ranch.  I built it and I can fix it.  Crashing is merely an opportunity to find design vulnerabilities and rebuild it better than before.   

[Bill from NH]

A blue spring steel version of this chassis would be nearly bullet-proof.

Just ask Steve Austin... 

 

Sure are a lot of Steve's in this thread - not that I'm complaining.

 

Nice work, Pablo.

[Peter Horvath]

Bill - This chassis came in an eBay lot of various and sundry slot parts. It was the only chassis of the lot that had any kind of maker's mark on it. The others were what appear to be Cobra or Phaze III chassis, I think?

[Pablo]

Peter, track test #1 of the "Steve's Racers" car today was a 100% home run. 

Didn't need to do a single thing to it.  Great power, easy to drive, no hopping or shimmy, smooth as silk.  Overcook a corner ?  No problem.  She digs in, plants her feet, and simply hangs the rear end out a little more.  After I drove it, Greg Gilbert tested 'er hard for about 20 laps - zero deslots.  Motor runs warm, not hot.  Mission accomplished.  Sending it to you on Monday. 

[SlotStox#53]

Great to hear your rebuild brought the car back to perfect Pablo

[havlicek]

...and Pablo does another one of his super-duper rescues!  Very cool man and an honor to have one of my motors running in your chassis Pablo.  Enjoy it Peter  (no wall shots though!)
