I love the curved top tube on this frame. It looks good and provides a more strength than the traditional top tube that connects to the seat tube much lower. This bike is looking great! Keep the pictures coming. Is it possible to get a picture of your dad on the bike when you are finished? We all like seeing bikes and bike projects come together, however, it is the your dad's reaction that is really the key. Of course, I am expecting that he will really like it.

Oh yea, that red bike in the background looks interesting.
