There's been a lot of talk about these lately. They're 12 gauge steel making them difficult to fabricate, unfortunately they're no longer available from Porsche, and tragically, nobody makes a replacement for them. So let's figure out what can be done.

The outer/longer one's fabrication seems well covered here: http://www.performanceforum.com/wesvann/91.../rd-9-1-08.html
But the inner/shorter one is another matter. Cary and his father-in-law created one out of a single piece, which seems to be the best method in order to maintain structural integrity since you're tying the two sides together. I'm currently working a scheme for a 2 piecer, but am thinking the 12 gauge will be super difficult to work with the weird curves. I really don't know how Cary's Superman did it! So here's an interesting question: I have me some 12 gauge sheet, but couldn't find any 14 (to cheat), do you think it has to be 12? Or do you think I could get away with 16? I'm confident I can get the bigger tie done in 12, so would the little one need to equal it, or could we get away with a little less? Also, do you think a 2 piecer for the little will work? (I'll post cardboard pics of my idea when I get them done) Don't hold back on your opinion. Thanks. |

If you know how to triangulate the curves then you can do what he does. Half skill and art. My 02. |

Here's where we're at while I'm getting ready for my career change. Super In Law is still working on repairing the rust on the cut out long first (pattern base) . Sorry to say the four that I've cut open have had rust damage. After he finishes that he'll start the hammer work on the ties. When we're happy with what we've created we'll hand it off to an ME at church and he'll do the 3D thing. They'll see if they can manufacture them and at what cost. They manufacture crop picking machines, primarily tomatoes. All I hope to get of that is the drawings. Then we'll hand them to Mark and see what his metal folks can do.
If that hits a dead end. I'll see if my new boss, Mr. Gamroth can get us into contact with one of his manufacturing folks. At the end of the day I hope Pete and his family at RD can do them. But it sounds like the entire next year is all scheduled out. My plan is to have Super In Law prepare both the left and right suspension pieces. Build two or three of each. Then maybe ship the long pieces to RD with one of each that we've created. We'll get this done ............ Off to a PCA autocross ................. |

After multiple cardboard experiments and a test with 20 gauge, I actually think the single piece is the way to go...

I went with thicker steel, made individual pieces and welded them together. I may still have the poster board templates. Let me know if they would be any help in development of these parts.
Process starts on post 130: http://www.914world.com/bbs2/index.php?sho...3957&st=120 |

I went with the 12 gauge and found that it really wasn't too bad. Formed in one piece with a vice, torch, and BFH. The first picture shows my multiple cardboard forms and the 20 gauge sample/practice pieces.

Some more pics. For the bigger tie I used the method as seen in the link.

Is this the right thread to lodge a complaint regarding the rear suspension design?
Nice job so far, keep it up! |

Yup, this is very helpful for me. I've been avoiding this task and focusing on other things.
Nice work, and thanks for sharing. |

Is it my imagination or does it look like seam welding could help the overall strength of this assembly?

(IMG:style_emoticons/default/agree.gif) This has been on my "to do" list for some time.
Nice work. |

Any interest in creating a PDF file of the templates?

I can see what I can do. I still have them, but it's going to be a long and busy week at work.

No rush, I still have a lot of work to do before I get back to the rear suspension.
If you're done with them and don't have a scanner handy, mail them to me and I'll scan them and post the scan. |

Is it my imagination or does it look like seam welding could help the overall strength of this assembly? I think you're absolutely right, I'm going to see what's up this weekend. I'm also thinking about adding a little triangular piece in this area: And an apology to mbseto, I should have known that as the early phone watcher I'd have nothing better to do at work this morning and should have brought the templates in to scan (I'll have to do them here at work anyways...). I'll try and see if I can trade an opening duty with somebody for later this week. |

Not trying to be a dick, but your seam welds look like they didn't penetrate the metal.
The spot welds looks right on! PS: great design/work! |
