Thanks Larry. I'm glad I didn't have to abandon a second project I wanted to put this motor in.  

 

I really added lots of braces to the rear axle to try to avoid that "bunny hopping" Bob. But

every angle winder GP I've built so far has been afflicted to some extent. We'll see what happens.

 

The finished chassis.......I HOPE!

It always works on paper, doesn't it?

I've gathered up all the parts to get this roller built. It's going to roll on repop

Russkit front wheels and K&B hard vinyl tires ground down to 13/16" diameter:

 

 

In the rear I've using repop Russkit "mythical" super wide rear wheels. I going to try out 

Paul's Slot Car Tires urethane tires for Parma "pencil" wheels:

 

 

Gears are vintage Weldon spur and modern Sonic pinion:

 

 

The guide is the ubiquitous Cox:

 

 

I wanted to use Cox Superflex lead wire but they weren't long enough for this

4 3/8" wheel base "long dog" F1. I'm going with Marklln train wire. It's the

slightly thicker wire on the bottom:

 

 

Time to get everything assembled........

Got the roller finished:

 

 

 

I kept the lead wires down low so they don't tend to lift the body

in its floating body mounts:

 

 

A couple of shots of the all important rear end:

 

 

 

The body is mounted and rattles around freely. The mounted body

worked out even better than I'd hoped.....which is sure nice for a change:

 

 

Everything fitting into a Slimline Ferrari body:

 

 

Track test is next.

 

 

[dc-65x]

Track tested the car on my Gary Gerding track:

 

 

1.  The track was wiped clean with Naptha

 

2.  Track surface clean with no tire buildup or glue

 

3.  Power supply voltage set to 12V

 

4.  Paul's urethane tires polished smooth with 600 grit:

 

 

 

5.  I ran just 21 laps as shown:

 

 

6.  Tires worked great for the first couple of laps but after 20 they look like this:

 

 

7.  I give up with cars more powerful than say a 1966 R&C cars with urethanes and no glue on the track.

 

8.  If more powerful cars with urethane or fish rubber tires without glue are working for others that's great.  

 

9.  I'm going back to a "dot" of glue before each turn and running a "rental" car around until the glue is spread super thin around the track.

I can't believe it's been a month since my tire test debacle. The snow, rain and cold kept the body out of paint for weeks. But that change this past week or so.

 

The first thing painted were these cool Ferrari wheel inserts:

 

 

 

New rear wheels with Alpha donuts:

 

 

The body, interior, Lorenzo's head, roll bar, velocity stacks and decals are all ready:

 

 

Finally time to put it all together.

[Pablo]

Love it 

Sir, what is the latest greatest spray for old waterslide decals, please. I would love a refresher course ......

[dc-65x]

Thanks Pablo,

 

Jairus taught me that a light coat of Testors clear gloss lacquer helps to prevent the old

decals from cracking.

[Pablo]

Thank you 

[dc-65x]

The car is all in one lump and I hope the late and great Lorenzo Bandini would have approved:

 

 

 

 

 

I'm still suprised that I got it to fit inside the Dynamic Slim Line Ferrari GP body:

 

 

To track test the car..............

 

 

..............I've added a mondo hunk of 1/16" thick lead that is as big as the drop arm will allow:

 

 

I also cut down (shown on the right) some fresh modern wheels and tires to 7/8" diameter by 5/8" wide per the 1967/8 rules:

 

 

 

Now I have to clean and lightly glue my track.........arg...........

[Bill from NH]

Rick, be glad your track isn't 220'.    '

 

The car looks nice, as usual.

[dc-65x]

You've got a point there Bill.   

 

I think I still have one of these "rental cars" in a drawer somewhere. It's going to be my "gluemobile":

 

 

I'm going to use it to lightly spread the glue around just the orange lane. 

 

When I first got the track I spray glued the whole surface and it performed just like the

the commercial tracks I was used to. But since I am the only one running, treating

just one lane should be much less upkeep.

 

 

[old & gray]

I remember my last bout of wing car racing. I would go to the track to test on a weeknight when the weekly races weren't running. I'd glue up a lane, run my test laps for an hour or so, then wipe the mess up with the track's preferred cleaner and rags.

[Pablo]

I'll guess the fish rubber wheels will work better than the soft wonders. I'll be watching .....

Hi, As I recall I cut down an inline chassis to build this car. And yes, many of the early angle winders hopped badly. That was part of the impetus in building the Puzzle Pan. It seems that it was important to put a brace on the back of the motor opposite the gears. Sandy

[Pablo]

A true pioneer has spoken. My ears are standing straight up 

 

The infamous bunny hop. If the motor is allowed to climb the spur it starts a hop.

It won't stop until it's braced

Hi Sandy,

 

Below is a link to Steve Okeefe's recreation of your fantastic "Puzzle Pan" chassis you referenced. 

 

It's a 5 part build and a great read:

 

Sandy Gross Puzzle Pan

 

[Tex]

from what I read a few years back, this chassis was very successful. why didn't EVERYONE copy it back then?

[dc-65x]

Hi Tex,

 

Yes it was successful. I know building one is more than a bit intimidating to me.        Steve Okeefe certainly gave good step by step instructions in his 5 threads. He even graciously supplied me with a "parts kit" to assemble one of my own. But I pull out the parts kit, look at the instructions, and put the parts kit away. With all that help I'm still reluctant to build one.

 

And to think Sandy Gross not only built it, he invented it in the first place.
