I am quite handy with most things, but I dont have any welding equipment or any thing like that. I am just a beginner. I have used welding equipment 20 years ago.
I have seen the longer than standard bikes, are these specialist built. I would love to build my own.
Perhaps I should stick to looking on ebay?
If you're willing to make the investment in tooling, it can be done. Frame building isn't rocket science. But you're also more likely to spend much more on tooling than you would just buying a frame.
Other things you might consider include a technical school shop class that would give you access to welding equipment and tools, or a dedicated frame building class such as those offered by United Bicycle Institute or Doug Fattic (among others).
If you want some idea of what you might be getting into before spending any money, you may download an early version of Tim Paterek's Manual for Bicycle Framebuilders without charge from Tim's website HERE.
The most recent version of the manual is greatly improved, but it costs US$75.00. This way, you can get your feet wet without a financial commitment. He also has some excellent framebuilding "how to" videos.
