Thanks for the reply's chaps!

So John - you wouldn't recommend 531 for fillet brazing?

@ Andrew - the course is over 7 days and fillet brazing is the main skill to be taught along with fitting and geometry's. They offer different courses and this one seemed to be the most in depth. I was a pretty good mig welder in my day and I was hoping those skills would come in handy. Re: insurance, so there is insurance out there to cover for tricky customers? I'm just looking to build a few frames for friends at the moment, maybe just charge them for materials to begin with while I hone my skills.

The main purpose of my post was to enquire about what sort of frame/materials would be a good starting point so that I can understand more about what people may ask for in the future and what materials would provide the best foundation and be most forgiving. I will look into True Temper, Thanks!

I'm not really looking for a bike to use myself, I have the bikes I need and am not really in the market for another. I want to fit a bike for myself to learn more about the fitting process and build something that will help me learn the skills needed to build good bikes for other people.

Thanks again,

Lester
