The internal wiring looms are here, so let's get busy.  Here is the down tube port with the grommet installed just to see how it looks.  The 7 X 8 mm hole was perfect.  The reinforcement is stainless, so Dan can opt to either polish or paint it.

The front triangle is ready for final sanding and cleaning for silver brazing tomorrow.  When I'm done brazing and the flux is soaked off, I'll weigh it with the uncut S3 seat stays, chain stays, and dropouts to get a rough estimate of final weight.
