Oh no, what have I done?
Possibly, it has something to do with limom and all his ruminations on buying a frame. I have felt some of the same pulls, similar urges, as he as expressed, but I also have thought a lot about building my own frame. Not because I think I could do a fantastic job by just reading a book, or a better job than someone who actually knows what they are doing, no. I'm pretty certain I would be lucky if the first one was even usable. Or didn't fly apart while I was riding it and spear me with a not-very-well-mitred tube joint. Even the second one may just be OK. And by the time I would invest in the tools and parts to build two not very good brazed lugged JRA frames, paid the emergency room bills, and considering some discounted but still somewhat market rate for the hours I would spend, I would probably be able to just pick up a nicer frame built by someone who knows what they're doing. So there's certainly nothing very reasonable about the idea, at least not if you look at it like that.
However. On the other hand. I would be riding something unique, something that I knew very thoroughly, something that I made. I could probably build it with Dura-Ace 10 speed downtube shifters if I felt so inclined. If I completed the project at all. Or if it held together. I have only skimmed the book so far, intending to give it a good read-thru over the long weekend ahead, but, for example, if you don't get the silver brazing just right, the thing can just fall apart, wrecking not only you if you happen to be riding it when it breaks, but also any sort of paint job you may have put on it, too, since at a minimum the separated joint will have to be cleaned back down to bare metal and re-brazed. One option he mentions is to rattle can it, and then ride test it hard for a few months to see if it holds together, then getting the spray paint abrasive blasted off, and having a proper paint job done, once you're reasonably sure the brazes are holding. Or else, after you finish, have someone who knows what they're doing inspect the joints. Come to think of it, I do know someone I could check with while doing it, someone who does know what they're doing. Time to give him a call if I go forward, I think. Or look into a training course of some sort.
Another aspect of the project, though, is that I lack a good space for working on building a frame for dozens of hours, including mounting jigs for mitering tubes, as well as the brazing process itself. Hmm, it seems like I bought another DIY book a couple years back that would come in handy. Let's see, where did I put that book....
