Interesting read on carbon fiber control arm manufacturing.

I think before anything CF should be used, have readily available titanium parts built or acquired.

 

If it's not being jumped, ti arms and swingarm will net you close to 10 pounds in savings alone.

 

Then, there are other things, like JT Machining carrier lightening.

 

Then, aluminum bolts..

 

In my honest, somewhat experienced opinion, CF is nearly pointless with all the titanium possibilities and other light weight parts.

Fair enough. Arms are built and are already light. Swinger needs to happen, but TT means jumps. Not big shit, but rollers, table tops, 20' doubles. Every guy that builds all the Ti stuff tell me chromoly.

 

None the less, sheerider11 you need this swinger?

When I rebuilt my hillclimb chassis, I shaved 11 pounds off that chassis, just by changing the front end.

 

The money you're trying to spend is better spent in the big stuff.

NVM, you don't want the truth.

 

I think CF sounds awesome!

It's amazing that each time you do anything, that is the only way to do something. Nothing wrong with a hybrid chassis. Plenty of them out there with minimal weight. Not trying to reinvent the wheel here. As I said, I just wanna replace Billit aluminum parts with machined carbon fiber parts. Use Ti hardware. Chromoly chassis parts (possibly CF uppers. And machine excess material where possible.

Yes, you are. Instead of taking several people's advice on serious weight loss, you're doing all this research and nonsense with CF.

 

Newsflash, hardly any 300' guys use CF. It's really not all that necessary.

 

The people here with experience with light weight parts/bikes are trying to help you get the weight down and save money doing it.

 

You're attempting to reinvent something that has already been reinvented and already has 73 newer/better/cheaper ways to do it.

 

We're just trying to help you be fast.

Tricked I'd have to say things here got mixed up because it was started with the idea to go super light and money isn't an issue...but then u are using components that have lighter options with plastic/aluminum/titanium/chromoly. I have all stk frames and set out to build super light stock frames. I also decided to use chromoly instead of titanium with certain components due to small weight savings and cost. But when u say money is no issue that's why u got the posts u did about light weight options etc

With all this material discussion i have to ask if anyone has a link to literature or formulas for figuring out what size/type material to use? I would love to learn about how to spec a material based on load but my hs education seems lacking.

If someone wants to share would 7/8od chromo .048 wall work for the main frame for tt? Or would it require to much bracing not to twist up after 1 heat?

All within reason. The vision is pretty much a short version of your stock frame. Now all of a sudden it's just stupid to have a hybrid. You should scrap that thing since the cool kids say full moly is the way to go now.

 

 

Aside from the frame, which components are in question? Already looking for a swinger. Rodger built the arms out of light weight chromoly. May just order a swinger tomorrow. Gotta get a box of stuff sent out to you to do some shaving as well.

I see how the front a arm set up can be lighter. That's one example. No one has built a stk frame to the level I have. There's a lot of components that can get things light...new machined components, machined lighter components, etc. I'd have no problem helping u but there's a lot to go over in a complete top notch build. It would almost be better to have me build it for u
