Servo update

More about servo's you ask? yes.  I wanted to finish off a couple things - tweaks, re-designs, things like that.  

I had a flash of insight the other day to make things even easier for the servo / switch movement.  If you recall the motion is different between the switch and the servo - circular versus linear.  I solved that with some bends and such to the wire... BUT... I've gone and changed it up again.  This time I mounted the servo up and down, versus upside down.  picture to come later.  This allows the arm to swing like a pendulum (a controlled one but none the less) and moves the switch arm in a perfect linear fashion.  The tweaks aren't needed and installations are a bit easier (ok a lot).

Facing the servo.  Up and down like a tortoise.  I didn't bend the wire around the arm too much and its still ok

From the side.  Notice the horrible job I did on the bending.

Seriously bad bending job.

Here's another one that I bent better.  Oh and used a lot of glue !

Here's a better shot.  The wire is piano wire and very stiff.

The switch and the servo wire poking out.  I usually put a bit of clear plastic around the hole.


I've gone and converted 4 previously installed servo's and two net new to this new methodology and am very happy with the results. 

Besides that, I haven't done much.  Entered some info into JMRI so I can start the automation, tweaked a couple of the loco's, still haven't speed matched my damn C-630's.
