I got the dropouts brazed to the chainstays and seat tube to the bottom bracket. I like to leave some tube showing inside the bb. That way I can get a little fillet for additional strength even though it doesn't need it. When the frame is complete, I will dress the inside of the bb. You can see one of the dropout windows is almost done.

I'm caught up on repairs, so back to work on Tinas frame. The bottom bracket is set for 60.5 degrees between the down and seat tubes. But, because her frame is so small, the that angle has tightened up to 55.6, you can see the difference from the protractor. Using my primitive benders, I was able to close the angle considerably. I will complete the final fitment in the tacking fixture.

I brazed the chain stays yesterday under my new heat lamp and it was quite nice. With out the bb adapter I need to determine the cable routings, I probably shouldn't have, but I was on a roll and couldn't stop. I pre drilled the exit hole for the front derailer cable so that shouldn't be an issue. But the entry hole into the chain stay for the rear derailer might cause me problems. I'm going to hang it on the wall until the adapter shows up.

I went ahead and started fitting up the 410 mm chain stays last night, but had to quit early due to the poor lighting in the garage. I can put on the chain stays and still have access to the bb where I will put in the front derailer exit port. So now I'm thinking matte black with a gloss black logo.
