Carbon for the forks, and both the seat stays and tube.  It's still got the alloy seat post that came with the frame set at the moment.

I have an. Extra cf seat post.. pm me if interested..

Loving this thread by the way..

Getting everything back together....

So very nice!

If you don't mind me asking. Where did you get the foam to shape the mold for the tail?

You can buy the foam at Lowes or Home Depot that comes in 4x8 sheets and is 2 inches thick, it's about $25. I cut it into blocks and glued it together to make a block the size I needed. I used a hand saw to get the basic shape and then used the wifes electric knife for most of the carving This stuff sands pretty smooth once you get the shape you want.
  Next I covered the foam with fiberglass and epoxy resin to make the mold. Don't use polyester resin, it will melt the foam.

   Here's a pic in the shaping process. As you can tell I made some changes along the way. The neat thing is that if you cut too much off, you can just glue a new piece back on and keep going. I'm sure there are some better techniques out there but this worked pretty well for me.

I was exactly thinking about using that material. It's like panel insulation foam, but I'm sure theyre all about the same.

Thank you

You can also paint the foam with a few coats of surfacing primer, then sand smooth, wax, and make a negative mold with fibreglass.

I've used the blue foam for that kind of project, but it gouges really easily.

That looks like the pink foam, I recall someone telling me that the pink foam shaped better.

I think the difference is one is eps the other is xps.

Eps is like a bunch of little balls glued together. The xps is extruded as a sheet and doesn't have a grain structure

  Ti tail light bracket:

This is beyond sick. I am super jealous of your impressive fab skills. Great work man.

Thanks!  Started out building resturant equipment Built a ton of Pizza Hut's kitchen stuff. All of those sneeze guards over salad bars...kind of like a trellis frame.....

Very impressive work, I love everything that is over engineered or made as good as it can be, but I think the lisenceplate and lights would be securily attached if the bracket was made in aluminum

  I think the only aluminum I have in the shop is some small pieces used for backing plates. I never did really like building things with aluminum.....no real reason. I do like the fact that aluminum can be anodized different colors. Ti can be anodized also...but you're limited on colors.
  Aluminum would sure be easier to drill and tap...

Beautiful work.
