That sounds really good. I can't get all the details from your post.
Can you please explain the steps in details or draw a simple diagram?
Thanks.

I want to play around with small wind turbine. I want to buy a 1 inch
ball bearing from RadioShack and use a 1 inch pvc pipe as the shaft. I
can slide the pipe into the bearing, but I can't figure out what I can
use to prevent it from sliding up and down. I want it to be as
frictionless as possible. I can just screw in a nut or something, but
that would have lots of friction and wear my bearing quickly.


If you can get a bearing that fits PVC pipe, the best way I can think of to
positively locate the bearing on the pipe OD is to get a 1" pipe joint (straight
piece you butt 2 PVC pipes into to join them lengthwise) and saw it in half,
then trim out the inside step the pipe would butt up against so the thing will
slide over the OD of the pipe, decide where you want your bearing and use PVC
glue to put this closely-fitting PVC collar where you want it permanently, then
put on your bearing, then glue the other collar on the other side. No rust, no
muss, no fuss.
