Tony, it's really marvelous that you bring your body of knowledge to LSR.

You do have the ability to apply previous experiences to this field.

It's a joy to see your progress.

Thanks, Tony. Interesting how the `Shred the car to dissipate energy`theory is certainly at work here. Certainly can`t argue with the result re driver safety, can you! I remember watching European Touring Car racing in New Zealand about a hundred years ago. The cars have changed a great deal since then..

This is the same direction we are leaning towards and will cut out some of the inner structure of the car and hang the body by the cage.  The hard part is anticipating all the scenarios and how the car will crumble in one of those scenarios. Tony

How about a capsule fabricated from the same material as the rest of the roll cage and covered inside and out with sheet steel. It would probably be easier to make for most as compared to a carbon fibre structure and in most cases probably better engineered for safety.

That is exactly what we are doing, but still haven't settled on aluminum or steel for the panels.  It needs to also come apart for cleaning, the salt is not forgiving. It will probably be held together like the REMR tub and will use the same style of bobbins. That way I can just make one run of the parts. The carbon is nice but is cost prohibitive to do, and besides where on earth would you find an autoclave big enough. Tony

You obviously need a friend really high up in the commercial aircraft fabrication industry.  grin grin evil

Almost finished with the in-car vent filter system. The whole thing from end to end came out at just under 6 1/2" and I am happy with the way they turned out even though I would probably change somethings around for ease of fabrication if I built another set.  I cant believe all the time it took to do this, but its worth it especially when the car runs at Elmo. That fine dust is a menace and nothing like clean air in the car.  shocked Tony



Buck for making the screens for the divers side vents.


The finished driver side of the clam shell.


High tech wood jig to get the tension correct for the latches.


Briggs and Stratton filter


One filter done and one more to go, the next part is to get the legs fitted.

Tony...You have me very interested in your Cage/Drivers Pod idea. I haven`t bent any tubing for the cage in my car yet, as I am waiting for my engineer pal to dimension the car internally so we can `build` everything on his computer. He did that for the Nash Healey Vintage Racecar he is working on, and it really worked out well. He could turn the car around on the screen, add or subtract tubing, body panels and even a `modeled` driver with helmet. I`m sure you have done all that already, but it was a new approach, and a great idea, to yours truly.....

Very nice, Tony! cheers

KP, It wouldn't be that hard to incorporate the tub into your build.  We are going to use the bottom pan of the car as the bottom of the tub and use steel and aluminum to build it out.  Just get your friend to do the FEA on the shape and where to place everything and you should be fine.  When ever I design a part of a car I remember what Jim Fueling (RIP) once told me "remember a fully loaded 747 takes off at about  185 MPH"  shocked

Buddy,  Nothing clever about the design on my part, I just copied the air cleaner housing on my truck (I have to thank the Ford engineers for the idea) grin .   Tony

Finally finished them! After fiddling around with adding individual legs I decided to take the easy way out.  There was no way I could get all four legs the same.  Depending on how they look in the car I may re do the legs a little shorter, but I will have to wait and see till then. Tony

Tony,
You need some belling dies!!! I make holes in every thing but always try to make sure I can form them with my belling dies. Just makes it look racy and it does stiffen the material. These are the belled holes on the rear crossmember of my modified.

Rex, I wanted to do that, but I didn't take the flare set with me to my friends place where I started the build last week and I didn't want to drive half hour each way to go and get the flare set. If I can get the tool to fit in the back  I will try and flare it, but its very small and tight and might not be possible.  Tony
