That is one thing I was wondering about.  Also if the graphite would actually function at RF.

Part of why I would like to homebrew a screwdriver....get rid of the fingerstock........

Idea is to wind the coil on a PVC core from flattened copper pipe. Then, use large copper 
tube over that for the vertical connection. Hope to add cap to the system to try for 160-10 
and allow for a longer coil. Another benefit is that another motor could be used to raise the 
whole thing up on a telescoped tube and double the length when parked.

May not work, but think it is worth a try....
