UUURG! Seems that whenever I get around to working on something I always run out of supplies. Today I got up early so I could start before it got too hot, and wouldn't you know: I run run out of mig wire. Now I have to make a trip all the way across town and lose prime working time.

I thought about buy the paint today since I have to go there anyway. Anybody have any suggestions as to what shade of silver I should use? Dave?

Wow pretty interesting thread! Can I ask you how you removed the tar flooring? I'm guessing heat gun and scraper?

Check out the car we just finished for our company....might be of interest for you!

Very kewl. Thanks for sharing. I have to do mine all myself at a rate of only about 5-10 hrs per week. I feel like I'm way behind, but I know once the cage is finished the rest should go pretty fast.

Yeah, the cage is the turning point then it starts going back together.

Contact Pete at peteywheat@d-zug.us or reaper@d-zug.us for info on paint color. If we can help out with info we'd be glad to!

good luck and keep up the excellent work!

Yep, just a scraper and heat gun. Usually comes up pretty easy. Doesn't take long, but its still a PITA.

Thanks! I have the heat gun and scraper, but I still am short a PITA. Still working on getting that put together!

Its been a while since I have updated this threat but I have a moment... Truth is I've been busy on other projects. Mostly I've had a deadline on a race motor for a customer, and I'm still trying to get the turbo back to the the customer. Its pretty much fighting me the whole way.

The last work I actually did on the car was about a month ago: I finished the rear section of the cage, and tacked in the sunroof filler panel.

I already have the next motor in the shop that needs a full rebuild and concourse restoration, and another motor coming in a few weeks. Also about to start an M96 (3.2 Boxster) project (will be for sale when finished).

My application for Rennsport Reunion was not accepted so the priority to finish my car has diminished. I will still be at Rennsport supporting a customer and his race.

This is the motor I just finished for a Carrera Panamerica race car.

Had the car out at the track this weekend for testing and breaking in the motor.

It been a while since I have been able to work on the car. Just too many other priorities getting in the way (like making a living). Today was the first time I touched the car since before Rennsport.

So I'm still working on the cage. The current challenge is to make the door hoops. The hard part here is that you have to make multiple bends with multiple angles (or twists). In many ways this is actually harder than the main hoop. I found this difficult to do with one piece so I broke t down into 2 pcs and machined a slug joint so I could twist it where I needed it. I bought a piece of 1-1/4" ID conduit (which is actually 1-1/2 OD) which is 80 cents a foot and allot cheaper to experiment with than dom at $8.00 per ft.

I bent the upper section and lower section till I got them where I needed and was able to join together with the slug. Now I have a jig I can use on both right and left sides.

Although I could have done this in with more bends, some clubs have limits on the number bends and total number of degrees so I limited it to two bends and it fits pretty good.

The main hoop parallels the B-pillar perfectly.

j911brick,

The way the hoop section is done is not legal for PCA or NASA and I suspect not for SCCA as well.

Scott

I know its not legal for Nasa, and I haven't checked SCCA (don't care either) in a while, but why is it not legal for PCA?

Pretty much everyone wants a diagonal from top left (above and behind driver's head) to bottom right of the main hoop. That piece should be solid. The horizontal cross bar is what should be cut.

Scott

PCA rules don't say that, and the diagonal is one pc.

"Also, the assembly must contain a diagonal (left to right side) brace from one upper side of the main hoop to a floor or unibody lower frame mounting point of a bar member on the other side to obtain the strength benefits of triangulation."

I did mine like the 935s had them.

Argue all you want and do what you want...it's your car.....but you really should build the cage the correct way so it can run with all organizations.

Scott

Actually that's probably not possible. Everybody's rules are a little different, sometimes contradictory and nonsensical. This car is being built for PCA so that is my first priority. This ain't my first rodeo; I've been doing this for 20 years.

Well, the side least likely to cave-in in a roll over is the side with the cross bar at the top. That's the side you really want behind your head...well, if you care about your head anyway.

I don't care how long you have been doing it...it doesn't make you right. You can build a cage that you can run with all organizations. The one you are building makes that unlikely.

Scott

.. all organizations? I don't know what the rules read now, but when when I was racing SCCA you couldn't build a cage that met the requirements of all classes in just SCCA.

As far as head protection goes: although your premise has merit, I'm sure the engineers at Porsche knew what they were doing on the 935, and the engineers at PCA also know what their doing.

That cage will be legal for SCCA when you convert the car to right hand drive. :rolleyes:
You could also weld in another diagonal to make an "X" and pass tech in any of the racing organizations.

Here is what he SCCA says (per 2011 GCR):

The brace shall either be in the plane of the main hoop, or extend from the top of one rear brace (described in 9.4.B.2.c) to the bottom of the opposite rear brace.

nothing about the requirement that the brace originate above the driver's head and no requirement for an X brace.
