Something sounds wrong with that statement???

  I've also found that either running a lag screw (long, with the head cut off, in an electric drill) with a similar thread in as a tap, or just forcing the sucker in cold with an impact driver, works pretty well too.

  A "cheap" way to help the screws in the pin block is a toilet bowl ring, made of bees wax. A little dab on each screw make it go is smooth. Averaging 5 - 8 pin blocks a year, I've had mine last up to 10 years,
