Bottom Bracket Takes Shape
Now Playing: A Journey Into Fresh Diggin - Quazimoto Meets Hisself
Here's the bottom bracket lug, about halfway done. The longer socket is where the downtube will slide in and be clamped. The tubing has been bored out for paint clearance for the first 2 cm of the socket, and the last 1 cm has an insert of smaller tubing brazed internally to act as a stop. Using a boring bar I squared off the end of the stop to remove any extra brass and provide a more precise location of the down tube . The socket will get a binder bolt and the front will be carved to look more elegant. The seat tube socket will also get carved to match the other lugs.

I also finished off the top seat tube lugh with brass too. I'll add some new pictures of that part soon.

I haven't work with brass for almost a year - I've been mostly welding - and it was a lot of fun to lay up that fillet.
