Have you read 'Zen and the art of motorcycle maintenance'? ;)
This book certainly influenced my approach to bike building (amongst other things). I have tried to include as many handmade components as possible. The best bit for me, was spending several hours stitching on the Elk-hide bar covering. It wont effect performance but it does (for me) illustrate the hand-made nature of the bike.
Have you read '[ame="http://www.amazon.com/Zinn-Art-Road-Bike-Maintenance/dp/1931382697/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1232544125&sr=8-1"]Zinn and the Art of Road Bike Maintenance[/ame]?' I learned a lot from that book (no joke).
