The boys here at Redstone have been working hard to get the EG ready for our first HC race of 2005! Brent Bertsch will be driving our B18C powered EG Hatch. Here are some quick pictures of the cage progess..

I like the plate on the shocktower though it looks like it could use some more welding.

 

Brent Bertch? Brent, what happened with Quan's old car? I thought you bought it. That car had a GOTO:Racing cage in it...hehehe

 

Brent still has Quan's old yellow coupe, but its not finished yet. (engine, suspension and misc. other stuff still need to started or finished. it should running soon.

 

looking good, like the progress

 

WOW, that thing looks awsome ....wish that way my car ........

 

almost stopped by on the way home from work.... looks good.

 

small preview of what the will look like..

 

very pretty...

 

The bar that goes from the intersection of the main hoop diagonal & horizontal to the passenger side front leg bottom, what is the purpose of it?

I can't see it supporting the main hoop or front leg. Is it for extra side protection?

 

it is a half petty bar. Real petty bars extend from the top of the main hoop to the front of the car and greatly increase the stability of the main hoop. In some apps they can be used instead of rear braces. The downside is that they impare visibility, so this is comprimise, not as strong, but does not impare vision.

 

Disclaimer: Not a fabricator. Just asking questions.

Rear shock plates look awesome. Wouldn't you want to weld them as much as possible though? Possibly sand down or maybe even cut into the body to kind of sandwich them better?

Would there be a benefit in extending the front of the cage as far forward as possible and following the A-Pillars and running right down the firewall?

I like the idea of some kind of petty bar and like the mounting location on the cross bar. Is it really even feasible to run a real petty bar in a Honda without obstructing vision or causing more harm then good?

Thanks. Cage install coming VERY soon. Doing lots of research.

 

First off I would like to thank Redstone Motors and all our sponsors for supporting our team for this season. The team is currently working on preparing 2 cars for H1 this season. The team will only be going to selected races this year. We will be doing allot of testing and preparing for the 2006 season, which we are planning on running 3 H1 cars. The team is also not ruling out the possibility of running with Honda Cup.

Redstone will be having a meet and FREE BBQ this Saturday March 5 to show the progress of our Eg Hatch and possibly showing our K series 2dr coupe (the old taxi with a face lift). There will be GT4 race off and prizes. Please come by. It starts around 3.

Now to your fabrication questions.
As far as the welding on the back plates, welders call this stitch welding. It is done so that you do not weaken the material that you are welding to. Most likely you would not weaken the shock tower, but this method is proven to be strong, so it was applied.

Yes it is a half Petty bar. It will act as extra support for side and roll over impact.

Thanks to all for the Honda Tech support especially Mike L and Mike Q (Come by any time)

whats going on there is called stich welding. I know a few cage builders who like to do it. As far as they say it just as strong as a full weld but in a violent crash it is less likely for the plate to be ripped out or ripped threw.

 

Thanks to everyone that helped with the cage....especially Brent and Andrew. I will have the finished pics up soon.....just got some more goodies in to put on the car so that will be next......dont forget about the meet here on the 5th ......

I'd like it further just a tad more (2") but you don't want to go all the way forward or else you'll loose alot of vertical strenght in the cage, the span just gets too long.

 

19crxHC & slammed_93_hatch,

Thanks for answering my questions about the rear plates. For some reason I had a COMPLETELY obscured view of what stitch welding was.

That was my thinking as well Dave. I see so many cages that end before the dash. I always thought it would be structurally sound to try and tie into the four suspension points. Ala rear mounts which is pretty common and penetration of the firewall which is not so common. I wasn't sure if people just didn't want to hack their dash up or the rules prohibited it or it wasn't the best answer.

So as you were saying about loosing vertical strength, is a Petty bar the answer there? As I asked earlier is it even feasible to run a Petty bar in a Honda, or I guess any production type car with out being a safety issue and/or obstructing vision? Any other ways to do this? Is a half petty bar worth it in most applications? I know it's not much weight.

Kinda off the wall, but has there been any discussion on gusseting and its legality in HC or IT? I'm well aware of the structural advantages. Mainly on the A-Pillars and possibly B-Pillars. I guess focusing mainly on HC rules. It doesn't really specify (at least from what I've found by reading) about them. So I guess I'm left to assume it is illegal? Although David has A-Pillar gusseting on his H2 ITR and I asked him about them and was told he got a 30lb weight penalty. Was that something that was decided by a director? And is it 30lbs and I can gusset whatever I want or is it 30lbs per pillar or per pair or what? The only weight penalty I found was 30lbs for penetrating the firewall. If I can gusset the A & B pillar's and only take a 30lb penalty I will do it in a second.

Sorry for the thread hi jack. If necessary I will start a new thread, unless someone has old links that I haven't been able to find while searching.

Thanks.

Yeah I'm with you on that. Also the area from the A-piliar to the halo around the drivers head would not work for me. I'm just tall. I'm jealous of you people who are short enough not to worry about that stuff.

 

i'm not sold on the "stitch" welding or whatever its called... the meeting joint where the horizontal plate and the vertical plate meet should be welded to prevent it from ripping under repeated stress. if the area rips in a hard impact the theory for doing this type of welding is out the window.

btw - i love the speakers in the doors...

I also like the idea of extending the forward down-tubes to the front of the door opening. It makes it a little easier to tuck firewall braces in there too. These pictures of my car and Jeremy's car shows the additional vertical support our cage builder added to the driver side to strengthen it.

Car looks good. Nice meeting you Graham and Mark! Good luck this season. Just stay behind me

 

Hahahahaa........Hey Andrie a deals a deals you said you'd go easy on us !!!! lol

the cage is not completed yet there is allot of touch up work that needs to be done before it gets our stamp of approval. Thanks for all the input and the finished product will be up soon. New Motor is going in tonight so now we'll have some more power...... keep an eye posted for the Dyno numbers !!

 

I'm always amused when I see a gutted Civic with speakers still in the door frames .

But seriously. That's hot .

the stich welding is going to PREVENT riping from occuring under all conditions. At least that is what i have been told, again im no cage builder but i know 2 cage builders who do it and one that doesn't. One of the cage builders cages has been around for 5 or 6 season at least and there is no riping at all and everything is fine.

can't wait to see what's going in here

 

cage looks good but are you adding any foot protection?
