I've had this happen; I spent a lot of time and money on a new vintage build, partly motivated by the idea that once finished I can show it to the world (well, the Bikeforum world to be precise). Then after I posted some pictures one not so nice comment completely popped my thrill... It can be painful but it is still just an opinion.
Unfortunately the OP picked the wrong forum to post his Colnago recreation. That doesn't make the people on this forum bad or negative, just not what you want to hear.
Well, at least no chopping was involved...
