    I have had this HS-1500 mkII screwdriver for a few years now and I am getting ready to sell the system. Lately I have noticed a slight slowdown near the bottom of the tube. Its not large or deep indentation but enough to make it noticeable when extending of lowering the antenna.
    I have looked at techniques used to remove dents in musical instruments and telescopes. During the cleaning, I have removed the motor and coil assy and have tried to kneed the dent out with a PVC collar on the end of a water pipe. The indentation is a little less than half way in the tube on one side. I have also tried to massage the area with non-marking connector pliers while the internal coil sleeve is position under the area. I have stopped short of heating the spot. I have seen metal rollers that may work while smaller metal pipe is inside. Then I have seen comments regarding tail pipe exhaust expansion tools that may work.
    The tube appears to be a pretty high grade aluminum with some tensile strength. The inside is a polished glossy finish that allows the coil assy to smoothly in one direction or another. There is a close tolerance between the coil assy and the tube interior walls.
    Has anyone addressed a similar challenge? I am willing to give it another go before putting it up for sale. It works, but just trying to make things work properly. The exhaust pipe expander would probably work but I am not willing to spend the $$ for a one time fix.
    This has been a awesome antenna that will handle 800w. If you have a method or idea, I would like to hear it.
    Thank you in advance.

    Tubes are available from Tarheel if you want to replace it. Or... Take it to a muffler shop, and have them use a pipe expander just enough to fix the dent.

    I agree with Alan; take it to a muffler shop. They shouldn't charge you an arm and a leg to remove the dent.
