Hey guys. Interested in improving upon my carbon layup technique with small radius, small overall sized parts.

Here's my most recent bike -> http://dillerdesign.com/random/bike/fat_bamboo_v2/DSC_0185.JPG

...and my first one (yikes, what I know now...) -> http://dillerdesign.com/random/bike/bamboo_01.jpg

I'm doing experiments of late involving inflation membranes (vs a full inflation bladder) and any alternative to vacuum bagging, as my parts don't have any flat reference plane to tape to / is generally a big pain in the butt =)

Hoping to be building custom carbon and bamboo frames commercially in 2013!

Cool bikes.

What type of material have you used for your bladders?

I've been playing with making my own bladders, and I definitely see the appeal.

I didn't intend to, and I still have to work out a show stopper problem when going higher than 30 psi, but to answer your question:

Smooth-On's reusable vac bag silicone. I originally bought a test batch to do just that, vacuum bagging. It can stretch more than 200% in practice and remain in one piece. I used word "playing" seriously, as I don't have it working to what I'd call effectively yet. At any rate, I can see the potential.

I originally got interested in the stuff after experiencing some bridging in my most recent frame, of which I do not have any decent pictures out of embarrassment. I overheated a bamboo pole through too might infrared light. I also put the bottom bracket shell in backwards... ugh. I hunt it up in my garage as a monument to what happens when I get impatient.

ok, thanks.
This method seems interesting but I think I will start with tubular bag folded back on itself,
or latex bicycle inner tub.
