Goirish, have you ever heard the term "wood butcher" ? Well a wood butcher's two favorite tools are a hammer and a pair of vice grips. I'am not saying that Airplanes 400 might be a wood butcher because he never mentioned using a hammer, only the vice grips! You already have the inch reamer, go ahead and get the metric one too. For those of you that may wonder where the hammer might be used......after the wood butcher rounds off all the wood screw heads with the vice grips, he then drives in the screws like they are nails with the hammer!!!!
