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.
