End of a day







The rod in the above photos was centered in the shell. It slipped a bit for the photo. It is of a diameter that is the centerline of the shell. The seat tube slips in and touches. The rod is removed then the ST is marked for coping. The shell is tacked and will be inspected for true tomorrow.

Been a while indeed!







Back at it after a long hiatus.. and my brazing chops were found lacking ( thank you for the spell check T.E.) . For all you 'new to building' folks looking at this, here is a case study of the importance of doing every day! Everything went well until the brazing. Using what I learned from finishing the last two frames, I wanted to minimize the tool cutting effort to 'face and chase' and prep the head tube. So I cut to length plus a very little bit. What I did not remember until some flux was fried that A) I just need to tack and B) the centering cones holding the HT are a huge heat sink. flowing the ends of the HT and the lug face proved impossible... Until I removed the tubes from the setup and finished off. I am still using too much silver and pushing bad torch position. The heat is up so.. I got carried away. The joint is fully flowed and strong however and The copes spot on. so all in all, a time for remembering and moving on.. just a bit more cleanup than I wanted to do. Rookie mistakes but the assembly is tighter than the first two so for that I am glad. Moving on... Seat tube and BBshell next
