This should give you a better idea of what I was talking about.
|
|
 |
The bottom adapter goes through the large
gear, through the spacer, then the small gear locates at the end and the bolt holds everything
together.
|
|
 |
With the bolt tightened down, everything fits nice and works like
it should. Next up is some wiring.

Running The Wire
I used this old cord I had laying around and cut off one end. This
cord is about nine feet long and will be perfect for this project.
|
|
 |
|
Now I have to come up with a way to run the wire out the
bottom. The adapter that you see below rests against the smaller gear.
What I plan on doing is putting a hole through the adapter, then running
the wire though that hole and through one of the widows of the gear.
However, the wire is going to need to make an 'S' turn before it runs
though this adapter.
|
|
 |
|
I plan on making a slot in the end of the cam for the
wire to make this 'S' turn. I'll use a small end mill to make the slot,
which will run from the center of the hole in the cam (threaded area) to
the center of the scribed lines. Those lines represent the window of the
gear, just like you saw above.
|
|
 |
I placed my drilling fixture back on the milling machine and used a 3/16" end
mill to make my slot. The depth is about 5/16" deep, which should be
plenty for my lamp cord.
|
|
 |
I used my Dremel to round over all the sharp edges so nothing rubs a
hole in the cord. Just looking ahead here so bad things don't happen
later.
|
|
 |
Here you can see I also milled a slot in the adapter and now I'm ready to try
it. Yes this could have been a hole but this will give the wire a little
more clearance.

How about that, it worked the first time!!
