 Here is the Di2 battery mount and cable port on the left chainstay. The port is barely large enough to get the zip ties through.  It is 7mm x 8mm, the Shimano requirement, but I might have to go to 7mm x 9mm to accommodate for paint millage.  Don't want to chip it.
An old Cinelli brake bridge and a new Paragon that we will use on Dans frame.  Uncut and undrilled, the Paragon is 10 gms. lighter while retaining the traditional look of the Cinelli.  Chasing those grams!

The blogger is finally back on line.  This is the pic I took this morning.  With the exception of the brake bridge, the frame is completely brazed, weighing in at 3lbs. 13 oz.  Since this photo, I have been working on the shore lines and smoothing out the lugs and bottom bracket.  These new pieces from Dazza have more surface irregularities than his other lines and require considerable more filing and sanding.  They are beautiful though and worth the extra effort.

After some birthdays, Mothers day, and other social obligations, I'll be able to get back to work on Dans frame.  All the braze-ons are on.  Here is the battery mount and cable port.  The hole still needs to be enlarged to 8mm to allow the zip ties to pass through.  Also, I will go over every edge inside the bottom bracket with detail files and sand paper to ensure there are no sharp edges to catch the wiring on.

I'm very low on oxygen, so I decided to finish the tank off with some of the braze-ons.  I use the Henry James Braze-on Gadget, but find that it allows the cable stops to rotate during brazing.  So this is how I set it up to assure a good alignment.
The chain stays are in and required very little post brazing alignment.  They are per drawing.  I weighed it again with the seat stays, and it is at 3lbs. 14oz.  I'm still shooting for 3lbs. 12oz. once the head and seat tubes are trimmed.  Need to run some errands, hope to get back to it today.
The easy stay is brazed.  Cool it, soak it, check the alignment, then start on the drive side stay.

Mitered, cleaned, sanded, fuxed, and ready to braze.  After brazing, I will do a preliminary polish on the dropouts as it's easier when they have the chainstay as a handle.  I need to lace the Powertap/Zipp in the back ground this week.  Anticipate brazing the chainstays to the front triangle on Thursday before Zimmys birthday party.
