After spending some time the last week going thru the National Guidelines to ensure my Bucket complies with eveything applicable, It be came apparent that no where is it mentioned about "wooding" or "steeling" out bodies, be it orig or repro. As far as I'm aware, most new glass bodies come steeled out, but I'm sure some don't, ie buckets and some other styles. What is the ruling on this Obviously the engineer will have to sign it off so whatever he is happy with should suffice. Shame this wasn't addressed in the guidelines, does this leave us open to the inclusion of intrusion bars etc?

Cheers and beers
Jimbob

I think you may be creating your own problem there Jimbob.
They can't knock you back for not complying with something that isn't there.
Maybe they have done us all a big favour by omitting this area from the guidelines. After all I'm sure we would prefer them to be more implicit rather than too explicit.
If your body has sufficent steeling and the seat and seatbelt mounts are adequate then your engineer should be happy to sign off on it.

That is a good question Jim. I can't remember ever seeing anything about it in writing either.

I did mention this to an engineer a few years ago and was told if I wanted street rod rego then wood would be OK but steel with intrusion bars would be better for full rego. Rather vague I thought and there was no mention about sizes of the steel or where you put it.

I am currently steeling out my A roadster shell using the "about here looks right " method. I probably have enough steel in it to keep a tank at bay but it looks the part and is not all that different from the bodies that come fully steeled out.

Most buckets I have seen have a very light steel frame usually made from 12 or at the most 20 mm square tubing. It is more to stiffen the body than add any serious protection for the driver.

I have often wondered how Ford would build a highboy roadster today. I doubt if it would have a chassis although the bottom edge of the body might be shapped to look like it has one. One thing is for sure: it would be infinetly stronger than anything rodders build and there would not even be as much as one inch of RHS tube in it.

I agree with Brett. If the engineer is satisifed then leave it at that.

Probably too many styles and models to cover specifically – pickup – roadster – coupe –tudor – steel- fibreglass, all would have different methods of steeling out.

Replacing wood with square tube and adding some cross bracing would seem a good start. Engineer would look for adequate mounting points for seatbelts, seats and brake pedel.

I agree bcal. Just asking the question incase I'd missed something.

When I started with the bucket I was living in Sydney and the only rego available was club. I was told by the SRC that wood was enough so thats what went in. Now with the possibility of full reg under the national guidelines I'm wondering if I should have steeled it. A bit late now with the paint already done

Cheers and beers

my '23 buick(built on a '59 chrysler chassis)had the original body's wood redone before i bought, it so i figured "why change something that looks and works ok"?the engineer i used, didn't enquire about it, and it never came into the conversation with him.the only time he talked about introusion bars, was when i mentioned building a rod on a '80 model L300 chassis, and that was only because of the year of manufacture of the chassis.
