James,
We've all been there, one step forward, 1 back , 2 forward,etc. Sometimes the bikes fights you and you have to hang in until it surrenders. I've often wanted to "fix" it with a larger f'n hammer only to cover it up, walk away, come back in the morning and keep going. I was whining heavily to a friend and he sent me this. I posted over my workbench.
Keep going, you'll be glad you did when you're riding it and somebody says to you "NICE BIKE!" when you're parked somewhere.

People who do what you do, to the degree that you do, deserve a great deal of accolades for your work. It is very tough for people to complete such tasks but even a greater talent to have a vision of the finished product and make the hands do what the mind's eye sees. The only way to complete this kind of undertaking is exactly the way you are.
