Those hoops are .120 wall 2" dom 30" in diameter---so close to 30" outside

Had a good solo day yesterday---spent nearly 6 hours coping the two bars over the helment in the cage and making a pattern for the 1/4" plate that will sereve as the top and as gussetts for the frt and rear of the cage joint.---next I will cut it out and then get a 16# sledge hammer and try to "smarten up" that dumb metal plate to the curve of the front and rear hoops  lol

We got the "cross Member-modified hoop" at the rear axle in today. I spent  3 beers worth of beingineering time trying to get it to tell me what to to about torsional rigidity--- from the rear axle to the eng bay---I feel more beer will be needed---(I did not recieve a clear message!!) lol

Small technical detail you guys might have overlooked. I think the valve covers actually go on the heads.

See , now I understand that you were interrogating me with the help of the truth serum in the car park at the Peppermill......... Maybe if we'd had one more you might have extracted something useful for your build....that's not saying that there's anything there, that you may not have already weedled out of someone else......You are the undisputed king of the ground-up, hands-on special construction builders....and you don't get there with your fingers in your ears and your eyes closed.

You could do worse, It's been a long time since I could get our car to sit on four axle stands at once ....haven't found a floor flat enough....it'll carry a wheel getting out of the trailer.......triangulation and bulk, with the added bonus of weight.....a brutal solution.No doubt you'll come up with a solution and it won't be complicated but it will be clever........

Our electric rate chanages at 12:00 noon so I try to stop around noon and chill out and run errands in the afternoon..

I had a good morning working behind the rear axle. I measured everything many times.

One of the funnies that happend at SW---someone was ribbing me about getting my car finished and said that it didn't take me long to build something.  My reply was that "I was trying to take a little more time the first time and maybe not have to rebuild it so many times!"


  I used every clamp I had still unused and welded the back of the car that the chute tubes will go through, and installed the top tube and notched the back and centered every thing. This thing is going to be so over built in some areas it crazy--- but having changed and rebuilt the back of the old car 3 times for various reasons my knowledge base is SO much larger than before.

These LSR special construction cars are all about trade offs. Tom Burkland and I have mused several times about the trade offs--Dr. G and I were talking about what he gained by the shape they chose and what they gained--{ AERO}-- but they are very LIMITED in what other options they had about changing things around the eng, ect, ect!!

One of the reasons I decided to build and new car was the old one was limited in width for a NA car I could not clean up the headers if I wanted to.  The old car woud not have paid a very big price with log manifolds if I had decided to run turbos.  I have been looking at an old attic fan that I scronged in Texas as a floor fan and wondering if I can "Southern Eng." into a primitive
Wind Tunnel.  The area around the Axles to Body, and the Exhaust exit will be the areas with the most to be gained!!

I promise to get a camera that I can operate soon!!

Wow! Such an outstanding job, I see the judges already awarded a blue ribbon! :wink:
