I've been looking at your stuff and it is very inspiring. I wonder how did you learn all this? Through school? Books? I study mechanical engineering and only a small part of the curriculum is dedicated to composites.
Any how, would you be able to point me in the right direction to get started?
keep it up!
First of all thanks!
Sure not through school, everything is just pure experimenting and collecting as much informations as possible. I have that luck that when I started with all this I get in contact with some people who work in some of our hi-tech composite industry. I get some material and slowly started working with it. Before that I made rocket fuels and of course also complete rockets. I made the tubes in quite similar principe and also working with some dangerous chemicals wasn't something new for me. Then I made a lot experiments. Really a lot. And slowly started with some bigger projects. Of course I was going step by step,..and I'm still going step by step,..and each step is better, improved,..
During all that time I get a lot of important informations, I also learned a lot. And after my third frame I'm prepared to do an even better frame. Something that will be really on a high level.,..I'll have to prepare more than 120 pieces of carbon for my PT4-NANO frame, also the materials that I use are now one of the most advanced. And as I mentioned, I get in contact with some people here in Slovenia who are working in the composite industry. We have quite a lot hi-tech composite companies (Akrapovič, Elan, PipiStrel, Seaway, etc.,..)
Berk, all very good stuff indeed.
Re the saddle, my vote goes to 2-wing, same as your decision. The lateral flexing forces are not that great to require any more. One drawback to this design (other than adjustability issue but there's no way around that) is the fact that the seat mast goes right into the center of the seat and takes out any suspension effect of saddle rails. Given the two wings are going to add a bit of weight, it MIGHT be useful to think about alternative structures that provide a bit more "give".
My manufacturer doesn't currently focus on seats etc, but I do have some thoughts in that regard.
It would sure be good if I would make it with some suspension, but then it wouldn't be that light and also the procedure would be much more complicated (already my procedure is quite complicated - carbon wings). But I'll make the combos now with only 2 wings, it should be a bit more comfortable. I rode with my PT3 for quite a lot kilometers without any probelms,..but it's true that I'm really quite used to a cycling saddle
