Spark plug gap

Whats the safest and easiest way to make the gap smaller in my new NGK TR55IX spark plugs? and what size gap should I use?

0.035" should work fine. I just give the side electrode a little tap with the feeler gauges to close the gap up or pry it with the little tool that comes with the gauges.
