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.  :-)

Cabling 2

I watched TV today more than working on the cables.  With the shift levers on the front of the handlebars, I had to turn them way inward so they wouldn't hit the tires.  And then they were running into the frame and hitting my leg on tight turns.  So, I turned the brake levers outward.  I mounted the brake cables.  Then adjusted the front shifter cable.  Still pondering how I am going to mount the rear shifter cable.

Here's a topview with the levers positioned and the cables mounted.

Here's a bottom view showing how I routed the cabling.

This is showing how I ran the cabling up to the front shifter.  I didn't have a handy cable stop to weld on so the cable would clamp.  So I took this ring that does the same thing off of another bicycle.  It works fine.

This is showing that the brake levers clear the tires by about 3/4".  You'll notice that I ran the brake cable over the top of the right arm.  I found that if I attempted to attached it to the bottom of the arm, the loop tended to push into the spokes.

This is showing the left bar all the way forward.

This is the right bar all the way forward.

Here's a top view showing a hard left turn.  All cables functioned without problems in neutral and extreme positions ... no binding.  Tomorrow I need to pull the seat and the rear pulley off so I can weld on some chain stops and cable guides.

Cabling 1

I've got to look at  some other trikes to see how they are doing their cabling.  I'm kind of stymied at the moment.  I put on one cable to the front shifter.  So I now have 3 gears up front.  But still only one in the back.  And no brakes.

Here's the one cable for the front shifter.

Here's the shift lever ... and the brake lever below it.

I did ride it up and down the street a couple of times while changing the gears up front.  Got some pretty good speed.  Particularly since I can only use the smallest gear in the back.
