Hi

For some years I have used some of the SCX models to produce 13uo frankenmotors as well. Nice endbell. The SCX motors are rebuildable while similar FKs aren't.

The powerplant is done. 13uo can, Di Mico can ball bearing, Falcon IV magnets/armature/endbell.
Thanks especially to The Dokktor for kind and korrect inspiration.
It is the coolest running little motor I have ever built.

Hi Pablo,

That sounds really neat! Got any pictures?

Pablo,
interestingly, those cheap FK motors run surprisingly fast compared to the old 517's or Mura "A"... and are a lot lighter!

[Pablo]

 

Airgap is now similar to stock F7; about 15 thou. Arm is centered. Endbell is easy to remove/replace. Hums just like a stock F7 and has LOTS of cooling to the comm

[havlicek]

Ha!...very cool Pablo. No doubt this setup will run rings around the old stock one. Can't wait to see the build!

Looks kind of "space age"!
Keep at it...

[Hworth08]

Pablo, you've out-done yourself!

If that motor had been around in 1966, it would have won every major race entered! And it looks straight from the factory!

[Pablo]

Thanks.

Next step : playing with old wheels

[Bill from NH]

Pablo, I would say it looks tamperproof, but we both know it isn't. Maybe if you use pintabs on your next one.

Tires & wheels next? Everyone is looking for chassis!

[Pablo]

I heard that if PdL suggests it, it's NOT tampering.

Bill, c'mon, you know I do things in stages. That's why I never have to "rework". The wheels, body, and powerplant mandate the chassis design, not the other way around

Gotta fiddle around with gears, too

[Howmet TX]

Hypoid gears, Pablo?

I use old brackets for this set-up by grinding out the top of the axle bearing holes and soldering a tube across. With plenty of bracing around and over the tube and the bracket arms it's as strong as necessary. Then that 13UO can snuggle right down, and there's room for a nice driver figure.
It may be difficult to find period korrect hypoids, but they were used at the time, so why not do it again?
Lovely project, by the way!

[munter]

I believe the slotit offset(hypoid)gear gives a benefit of 1mm lower for the motor postion.
The only other hypoid I've seen is a Strombecker and its huge.

[Pablo]

 

Just a fun build, nothing more.....made from parts on hand.....the modified vintage 13 uo will be up like a stinkbug in the rear, but sloped downward towards the front. Limitations of the bracket design, and all....I left it stock...Wheels are vintage, tires are modern rubber 750..... Cox vintage Crown......

Good opportunity to test the (D3) theory of the evil Doktor that says the motor riding up off ground zero a little is of no concern....we shall see....

I can hardly wait to see what the horsepower of the modified 13uo does to those skinny rears....may need some Koford Heavy .....or a rethink...tried to make it look like the real car, again, given the limitations of the bracket, body, etc.

I have a track to test on now, so I have no excuse for poor handling. I'll build a stiff, light wire frame and test.

FYI, I love critics, especially in the planning phase

Critics loved? OK!

This car really deserves reproduction Russit wheels! That's what most of the pro used in 1966 along with K&B rubber front tires and Tate's foam rear tires. I believe the "Vintage Police" will allow modern foam tires though.

[TSR]

Pablo, you can get Russkit repro wheels from Electric Dreams and proper Ferrari inserts from Al Penrose...

[Hworth08]

Philippe,

Do you know which K&B tires the pros used on the front? From what I see on ebay, K&B made many front tires.

[Prof. Fate]

Hi

I saw the movie Grand Prix in Cinerama opening day. From open to close living on popcorn!

When the Pactra version of the body came out that August, I bought the body. I still have the car. The way I hooked up with philippe was looking for spare parts to keep this and other oldies running.

Won a LOT of races with the car.

Anyway, the chassis looks a lot like a modern D3 chassis. 2x047 pianowire mainrails, sold brass sheet forward of the motor, hemi motor, simco Jet Flag, cox mag fronts with turned down solid rubber tires turned down to 750, 1/8th axles, cox crown, associated black rears.

Second race the motor lost the can bushing and I started doing "franken motor" stuff with it. These days for just RUNNING, it has a modern 30s 16d.

Hi Pablo,
Good to see you back at this project.

IMHO, since I'm being the critic. the rear wheels first selected I liked, wasn't crazy about the front wheels, they appear to be threaded axle style. While these latest ones are grub screw. What is correct? I don't have a clue build it for what looks nice instead of what's correct, that's my take on it.

[TSR]

Paul,
I think that if you use the standard rear wheel as a front and the extra-wide rear as a... rear, you will be better off. Russkit rear tires up front and K&B or Monogram slick on the rear.
Here is a pic of all four sizes:

Don,
I have several sets but they are loose. I have to figure out the actual stock number one of these days...

grub screw

What the heck is a "grub Screw" ? A new Bass fishing lure ?

J.P. Sarti, to Nino Barlini ( in the hotel hallway with two Japanese girls on his arms): Nino!! Two?!!

Barlini (lecherous smirk): They are very small...

[One_Track_Mind]

set screw.
either I heard of them called a grub screw or it's a made up name I came up with?

Let's not forget I was born a HillBilly in West Virginia! I'm fortunate to support the state thru Ohio

[Pablo]

grub screw

For a second there I thought maybe you were referring to my height

[Bill from NH]

I always thought "grub screws were the ones with slotted heads for use with a straight-bladed screwdriver. The ones with the 6-sided flat holes were Allen screws. Then you got Bristol Spline & Torx screws. All have been generically called set screws.
