Marking the drilling hole pattern in an engine mount is an important task that, until now, was handled in a less-than-precise manner. When improperly drilled, the holes can over-stress the mount, cause the mounting bolts to bind as they are attaching the engine to the mount, or even worse, allow for destructive vibration. But with the Great Planes Dead Center Engine Mount Hole Locator, modellers can quickly, easily and accurately indicate the exact spots where the hole should be. And it's so affordable, it'll be a welcome addition to every flier's tool assortment!
