    Take your time...

    #1 - Wear safety glasses
    #2 - Practice on scrap pieces.
    #3 - Use the right size/type blade for the job.
    #4 - The shoe is meant to be a guide for leveling and stability. Hold the shoe tight to the pipe. Lock your arm against your body for stability. When you start to cut while keeping the shoe against the pipe, let the tool do the work. Eventually, you'll get a feel for when to apply more/less pressure. Just like welding/soldering it's always good to practice on scrap pieces to build confidence.

    Galvanized is not so hard to cut. Use a new metal cutting blade. Are you sure it's not cast iron? That's different!

    The lennox gold will do the cast iron too... Recently I used the same blade
    1 1/2 days on a job cutting cast and galv.

    Try a Milwaukee "Torch" blade.
    Lennox is the name I usually get for hole saws and blades, but the Torch's are fantastic.

    cut

    wrap a paper strip around the pipe and mark a straight line. The cut to the line.
