Okay, I must admit. A smile came over my face when I saw how that the middle chainring worked for you. I didn't think that it was possible to put it back but you certainly proved it!
That was pretty cool. Shows how much you can accomplish with determination. Bravo to you, ddac! I'm actually pretty excited to see how this bike goes through the changes. Please keep posting.
The only thing that got me a tad nervous was: Wear shoes when you work with flame and melting metals!!!!
Good on you, ddac!
