factory has worn off. The cordless drill was also new last fall and hasn't been used for anything else. And when I use an AC powered drill I can tell it is taking more torque especially in the last few inches. Other factors could be friction in the winch and pulleys. And the angle of the tower - how far off it is from vertical. A dedicated motor would be convenient but that's another project. 73, Eric - K6EP At 05:59 PM 7/13/00 , Pete Smith wrote: >At 05:15 PM 7/13/00 -0700, Eric Pearson wrote: > >This might be a good time to ask my LPT question: I've had a low > >profile tower since last fall.
