That's the ticket! Getting the experienced guys to take the newbies under their wings. Nobody is so good that they don't have to "pay it forward."

 

We were all newbies once.

Anybody have any feedback for my build on the rear wingie pans?

Seems like unless braced real well, they'd be breaking off like a potato chip every time the rear ends takes hits.

 

I'm considering 3 options:

-do them exactly as the article shows

-extend the plumber wires back and make the pans longer, with another Tony P. type "U" hinge back there

-make them separate but give them their own Tony P. type "U" hinges

 

Keeping in mind no one has expressed any desire to buy the car so I will be playing with it myself.

In fact, I'll be running it hard.

If I am understanding your question. The stationary part of the pan has a butt joint and you are worried about its strength correct?

 

My feelings are it is very well protected by the wheel and the pan extension wires that keeps the body of this stationary part of the pan. So why the concern? It was good enough at the time in the heat of battle for Bob and others that used split pans.

 

My question is what is the effect and theory of split pan and what is the dates it was used? Does seemed to be short lived.

[Pablo]

Whatever you call it, this type joint has little strength in actual practice.

A hinged pan can move and flex and even bend.

Here's what I mean:

 

 

Snapped it right off with my fingers like a potato chip.

The leverage it provides causes it's own demise

 

 

Not arguing, and I can appreciate it if you don't agree.

Doing it Bob's way is one of my options, but I'd be remiss in my duty if I didn't see a weak spot.

 

Bob had lots of good strengthening ideas to preclude damage. If he was here today, would he agree with this change?

Just put some small L braces on top that will hold them on.

Thanks Tony, that sounds like a perfect solution, will do

[tonyp]

That's what we started to do as they tended to fall off. Lol.

[Pablo]

Yup. I think Bob would be OK with that so I'm good now.

Thanks Tony

I do agree it is a week joint,  I have not seen that L brace before, It will help for sure. Are you using sliver solder at that connection?

 

I  still have this question,

My question is what is the effect and theory of split pan and what is the dates it was used? Does seemed to be short lived. maybe it was more trouble that it was worth.

For reference, below is one of the last, if not the last chassis, Bob built.

 

He gifted it to me in about 2011.

 

If I would of decided to race it seriously, I would of added some bracing, including wire wrapping the axle, for sure.

 This beautiful chassis, I'm sure it is a treasure of yours and a great reminder of your meeting with the late great Bob Emott.

[Martin]

Now I have seen L bracing. Thanks to Jairus.

Martin the split pans were a way to keep more weight in the back of the chassis in the corners when the body would unload the main pans.

I can, but silver solder alone isn't going to prevent breakage the way it's designed.

I'll add some braces like Tony said, and everybody will be happy

[Martin]

Thanks Tony, the split pans seem like a good idea, how long were they used and what date were they discarded by the pros?

Do you know the reason they were discarded? were they getting knocked off or were they more trouble than they were worth?

Thanks for your time and sharing your knowledge.

[tonyp]

Martin. I would think we used the split pans for about a year or less. They, after much use were decided they did not do much especially as the glue got thicker and the chassis went to more forward weight. To compensate for the stickier tracks.

Mike, that is one very nice chassis you got a hold of. Emott's builds were always something to admire and learn from.

Tony, thanks for the reply. I am very interested in the dates of that split pan use, it will help us date chassis with split pans for historical accuracy.
