Who are you hurting? No one. Does it make you happy to find a cool bike, fix it up and find the correct parts to make it right? If the answer is yes, then keep on keeping on. Let your heirs worry about what to do with them after you are gone. I am new to this hobby, just stripped and rebuilt my first bike. I didn't get everything right, and I know I have a lot to learn. But I can honestly say, the time I have spent working on and polishing that bike is some of the most peaceful and relaxing time I have spent in a long time.
