Carbon Fiber shift rod (updated)
Sept 12th, 09 -
Now confident in NEW carbon material used. Much higher frequency and rated for actual torsional loads. the other "pultruded" style rod didn't seem, and clearly isn't up to torsional tasks. Also, doing away with safety pin, as I was told drilling hole will actually make it weaker and to trust the epoxy.. I do now that it's done.
Here's what the new stuff looks like. If you must have one, and you want to be a baller, just pm me... lol No one will ever see it though! Shame.
Heres the updated pics. MUCH better.. very confident.. way overbuilt at this point. I still wish people could actually see it when it's installed. But.. it does save me a couple pounds. and I got some great experience with this stuff.
Just to give you a peek at what going on in my head and what I've been working on for some time now.. Really, been waiting on.. just got some the last of cnc parts in. It is to be epoxied and smaller safety roll pins to go in. Saves a whopping 2 lbs. Cost about $200 in parts. It is really just an exercise in working with carbon and aluminum together. I have much larger parts Im going to be doing this with. intake manifold and Torque tube.

Cool idea. I re-did the stock one welding a larger tube to the end and utilizing a needle roller bearing, The result is NO play and an extremely short throw, much like my Tremec TKO2 in the stang. I also re designed the short shift block on the trans, the damned thing thing kept loosening up so I went a buddies mach shop and wire machined a new one that actually has a D shape hole in it that fits the shift shaft as opposed to an open hole with a bolt. It works alot better. I need to hold a up a rule and measure the actual shift throw but it's extremely short.

Keep up the good and interesting work. As far as I'm concerned I love that there are still guys out there doing new stuff for our cars. In this respect we're very lucky. Thanks.

so do you buy the tube then make the other bit's ?
I'm thinking about grafting FG and carbon to the cut down 944 S 2.5 manifold thinking of making a little hot water and vacume rig to make it clever

Correct. Depending on what epoxy, you will have minimum and maximum clearances for curing, along with different temps and times. But I might be thinking of overkill there as some epoxies are extremely strong. Just be sure they don't break down at certain temps. (250 at head flange). Sounds like you might be past that info at this point though. But yeah, I just bought the carbon tube, and had the aluminum parts cnc'd
