No such thing as what??? Did I miss something here????

yeah, you missed the S in FD3S when you posted the thread. he was just picking on you.

Sounds really cool. Can't wait for some pics!

how much does a carbon drive shaft run?? Im sure there kind of heavy.

Originally posted by RX Steve If anyone can copy my unobtanium steel sleeves in Titanium or if Jim reads this I am interested. I have a lathe but no source for the Ti. If anyone can reccomend a good source I'm interested. As for your carbon fiber... be aware that those who are producing "copies" of other vendor's parts are providing people with the carbon fiber look, but that their production process is probably the same as that for fiberglass (wet lay-up), so the weight is probably very similar also. For true lightweight carbon fiber components, you'll need to find someone who uses an autoclave to cure the components at high temperature and pressure, and uses "pre-preg" material. Pre-preg carbon fiber is pre-impregnated with resin at a production facility, rolled onto spools, and then frozen to prevent it from curing. The resulting material has a precisely controlled resin volume (unlike wet lay-up, where fiber is layed into the mold and then resin is applied) and will be 20-30% stiffer and stronger than an equivalent thickness wet laminate. Panels made from pre-preg can be significantly thinner because of the increased strength, and are therefore lighter. |

Originally posted by RX Steve The wiring is going well. I am eliminating miles of this stuff. The ABS and air bag take a huge amount of support systems! I am scrapping it all. In the upper left corner of the picture below, you can see the huge amount of wiring and parts that I eliminated from my engine bay harness alone. Compare the thickness of the remaining harness to a stock one, and you'll see where 20+ lbs. of my weight reduction came from. :) https://www.rx7club.com/forum/attach...postid=1041449 |

Thats a lot of work there Jim!. Can I send you my TII harness for a rebuild/refurb?

must be nice to have money to burn on a negative return investment
some people are apparently not suffering in this economy.... |
hey Jim,
you must have a VERY understanding wife who is ok with you filling the house with old RX-7 wiring harnesses :) |

Jim,
Prepreg aint what it's cracked up to be. We have some resins that are Rom temp cure that work just as well or better than the prepreg. I have produced carbon parts before and know quite a lot about it. I have the ability and the facility to vacume bag every part. If done right it is just as efficiant as any carbon system can be. Mosler uses it on the MT-900 right next door to my wharehouse and they are very helpfull. I will be using a couple of tricks these guys spent years learning. In return I have some for them as well. I have a system they say won't work and they want proof. So trading is working well. The PPF seems to be well made with little excess weight. I think I have a solution for it too though. The driveshaft is not a part I want to try myself. I will however be doing lots of other parts along the way. I am doing the titanium suspension parts as well. I need lexan or something better if it is made. FAL was supposed to be doing a kit but all they did was the rear glass. If anyone can help here I would really apreciate it. The car comes down (It's been stored in my loft) this week so that I can begin reassembly. I'll keep you all posted. Steve |
