Rear Derailleur Cable

I finally welded on 4 cable stops and 2 cable guide rings.  I've heard that the less overall cable housing you have, the less friction.  So I figured to eliminate the length up behind the seat back.  And on the underside of the rear fork.  Here are the photo segments starting at the rear wheel.

Notice the wire under the rear fork.

Here's the run paralleling the seat back.  I used a small length of cable housing to  bridge up to the rear fork.

The cable housing runs behind the idler pulley and through the 2 guide rings ... then up the right handlebar.

Here I'm attempting to show the full length of the cable run.  I think I've got it adjusted so it will shift the full run of the gears.  I need to bolt the seat back on, set the foam pieces on.  And test ride it up and down the street.  Once it is fully functional ... then it will be time to strip it all down and paint it.  sigh.  :-)
