Problem with putting a hole in the interior without being able to view the entire underside of the roof should be pretty obvious. For one, where do you think someone would put a thicker piece of plastic or tape? Exactly, right where the hole lines up with the interior. Second, without being able to see the bottom of roof, you cant tell whether something like that is there, or if they sanded the body everywhere but that spot. SMH

I certainly took in consideration the scenario of a racer trying to build up that measuring area.

 

But in my IMO, at least with this body, you can easily spot if the area has been built up in that small area.

 

And if there is a question, that interior can be partially detached to access the whole inner roof.

 

I just don't think you'll ever need to do it.

 

Not with Noose and his hyersonic eyes, anyway. Lol

 

I would just hate to have a racer suck in his interior, in the race, after hastily refastening it in the tech area.

Never need to do it? You havent been to many Retro races have you Mike? What is that, a Cyclone body? I cant remember the last Cyclone body I saw being raced. Irregardless, we are where we are because a precident was never set early on in regards to body thickness. In fact, I can say Ive never seen the roof measured period, probably because nobody ever had an accurate way to do it. The racers know this, and have taken complete advantage of that fact.

Not never needing to measure the roof.

 

"Never need to do it" as in having to unfasten the interior to measure it..

 

IMO, the tech person could easily see if the measuring area in the middle of the roof was tampered with to make thickness.

 

Looking through the side windows I can see the whole underside of the roof in the area of the Noose painted "85" that dominates the roof area.

A simple push test on the roof or hood by an experienced tech inspector (rhymes with moose) would reveal whether more inspection  with a caliper is needed. No need to delay the race by testing every car.

You said I just dont think you will ever need to do it. Meaning removing one side of the interior to be able to see the entire underside of the roof. I totally disagree with you, in fact, if there is any retro class where you should allow the interior to be mounted to the chassis its Stockcar just for that simple fact. You absolutely need to see the underside of the roof. Slot racers are pretty crafty when it comes to making you think its all good rule wise, when in reality nothing could be farther from it.

Is this body legal? How is it not measuring .015 anywhere if that is supposedly the original thickness of the lexan before pulling it? And Im expecting that this was an off the parts wall body

Chris:

The vacuum forming process will always produce a thinner body than the original material thickness it was made from due to the heating and stretching inherent in the process.  The areas that stretch the least (the roof) will be thicker and the ones that stretch the most (the sides) thinner, hence the different thickness' allowed on different parts of the body.

I get that. But an .015 body should be .015 somewhere.

Go grab a RTR charger body of a parts wall. Itll measure.015

I doubt it.

 

Maybe if RTR started with something like .016" - .017" material (oversize .015")

Not busting chops Swiss. A RTR Charger is noticeable because he starts with .015. It may be the only SC body thats meets the spirit of the body thickness rule

 I'm not sure what you are getting at.

 

Does it say anywhere in the rules that a particular part of the body has to measure  .015" ?

 

Did my 5 year old  VFC Charger, that Noose and Edsel gifted me for staying at my house at the Sano, that measures .0135", somehow offend you?

Geez Swiss, no. I said Im not busting chops. Im saying that for years SC bodies seemed to be getting thinner. IRRA has been around for a long time. RTR got his body approved and have been not only consistently thick but most similar to the SC body thickness of 10 years ago.

Did my asking if you could compare your VFC gift to an RTR offend you? You demonstrated that you had a useful tool at the ready.

Sorry to ask for your cooperation in comparison of two bodies of similar type

As I said in post #27 it is not the bodies hanging on the wall that are the problem in most cases.

Chris:

There is always a tolerance on raw materials, as Mike said RTR might have a supplier that delivers material on the high side of the tolerance.  Even starting with slightly thicker material you might still not get .015 on the roof, much less anywhere else on the body.   it really depends on a lot of factors in the vacuum forming process.

Hook up bodies are my favorite.

The RTR Stocker has to be one of the thickest bodies out there, they feel like rental car bodies.

I told you I didn't have an RTR Charger in stock.

I am sorry but because a racer has a thin body does not mean they are cheating. 

It means they found the thin one.

 

The problem is where did the thin ones come from, my kitchen oven or an approved supplier.

If it their oven then they are cheating throw them out. 1. they did not get that body approved. 2. They knew what thickness they were using.

 

It an approved supplier made thin bodies then un-approve their bodies. They know what the market is for these bodies. They know what they got approved. They did it to help their friend/racers run better. They cheated the system. Throw them out of IRRA or what ever group that approved a thicker body than what they make for some.

Why I quit selling clear bodies about 2 years ago (other than my CR007 M7, mostly to distributors)

 

I don't have the time or patience, anymore, to deal with the "pick me a thin one" requests.

 

PS - sincere apologies to CD for being snippy with him. I had a lot of packages to get out.

 

I should of never got involved in that conversation considering that was the situation. 

 

Again, apologies.

And I just bought a bunch from your wall last week! I included one which I knew to be thick but wanted to check it out. A few other parts from your well stocked place as well.

Just as I asked you in the Retro East FB forum, what happens when Company A's body is backpoured and pulled by Company X or Individual Z ?

 

Who do we throw out since it will most likely not be publicized?

How much weight is being shaved off these stock car bodies?
